  Bernie Fette (host): Hello once again.
• 0:16
  Bernie Fette (host): This is Thinking Transportation-- conversations about how we get ourselves and the things we need from one place to another, and what can happen along the way.
• 0:28
  Bernie Fette (host): I'm Bernie Fette with the Texas A&M Transportation Institute.
• 0:33
  Bernie Fette (host): The US- Mexico border stretches almost 2,000 miles, includes four American states, and sees more than 4 million truck crossings every year.
• 0:45
  Bernie Fette (host): The operations involve a wide range of institutions and government agencies-- both public and private sectors-- representing both countries.
• 0:54
  Bernie Fette (host): And of course, cultural differences come into play, as well.
• 1:00
  Bernie Fette (host): With that kind of complexity, there's a lot that can go awry.
• 1:06
  Bernie Fette (host): Here to help us understand how things keep running smoothly, and why that's so important, is Rafael Aldrete, a senior research scientist for TTI and Director of the Center for International Intelligent Transportation Research.
• 1:21
  Bernie Fette (host): Thank you Rafa, for joining us today.
• 1:25
  Rafael Aldrete (guest): Oh, thank you, Bernie.
• 1:25
  Rafael Aldrete (guest): I'm very glad to be here and I'm looking forward to a chat.
• 1:29
  Bernie Fette: I was thinking we might begin with kind of a big picture description of the US-Mexico border, based on the very limited amount of web searching that I did.
• 1:40
  Bernie Fette: Just a few factoids that popped up for me.
• 1:43
  Bernie Fette: It's almost 2,000 miles long.
• 1:46
  Bernie Fette: It involves four American states.
• 1:49
  Bernie Fette: It's the busiest border in the world, which I didn't know until I read that yesterday, based in part on the fact that there are more than 4 million truck crossings across the US-Mexico border each year, and more than half of the cross-border trade comes through entry ports in Texas.
• 2:07
  Bernie Fette: Did I miss anything important there?
• 2:09
  Rafael Aldrete: No, no.
• 2:10
  Rafael Aldrete: That is correct.
• 2:11
  Bernie Fette: Okay.
• 2:12
  Bernie Fette: Then could you help us by painting a picture?
• 2:15
  Bernie Fette: Maybe describe for us how the border is important on a macro scale first.
• 2:21
  Bernie Fette: Economy, jobs, gross domestic product, any other meaningful measurements that you might use whenever you're explaining this to people.
• 2:29
  Rafael Aldrete: Well, you described that 2,000-mile long border, and along those 2,000 miles of border, we have 24 commercial crossings, commercial ports of entry from California to Texas.
• 2:42
  Rafael Aldrete: Mm-hmm.
• 2:42
  Rafael Aldrete: We have 43 passenger vehicle crossings.
• 2:45
  Rafael Aldrete: We have 36 pedestrian vehicle crossings and 18 for buses.
• 2:51
  Rafael Aldrete: And then we also have nine really important crossings for rail.
• 2:55
  Rafael Aldrete: So it's a massive set of infrastructure that we have at the border, and its impact is felt throughout the US economy.
• 3:03
  Rafael Aldrete: So just to give you an idea, in 2021, the US goods that were traded with Mexico reached$661.1 billion.
• 3:13
  Bernie Fette: Billion with a B.
• 3:14
  Rafael Aldrete: Billion with a B.
• 3:17
  Rafael Aldrete: 276 billion were exported from the US to Mexico, and almost 385 billion were imported from Mexico.
• 3:24
  Bernie Fette: That's a lot.
• 3:25
  Rafael Aldrete: About 82 percent of this merchandise is crossing the border by truck and rail.
• 3:31
  Rafael Aldrete: So it's a big chunk.
• 3:33
  Rafael Aldrete: Okay.
• 3:33
  Rafael Aldrete: And like you said, Texas has the largest share of trade with Mexico.
• 3:38
  Rafael Aldrete: So for Texas it is even a bigger deal.
• 3:42
  Rafael Aldrete: To put this into a different kind of perspective, I can also tell you that in numbers of trucks you mentioned how many trucks were crossing per day.
• 3:49
  Rafael Aldrete: So to give you an idea, in 2021, we had about 7 million trucks crossing the border.
• 3:56
  Rafael Aldrete: This figure 7 million is a, an increase of 47 percent in the last 11 years.
• 4:02
  Rafael Aldrete: So since 2010, the number of trucks have grown by about 47 percent.
• 4:06
  Rafael Aldrete: So it's almost by half.
• 4:08
  Rafael Aldrete: Mm-hmm.
• 4:08
  Rafael Aldrete: So the, the growth is very significant.
• 4:12
  Rafael Aldrete: Other figures that put in perspective how important is the border is when you put the amount of trade in US dollars that crosses every day.
• 4:19
  Rafael Aldrete: We are talking about one and a half billion in goods trade with Mexico every single day.
• 4:25
  Rafael Aldrete: So that's a huge amount.
• 4:26
  Rafael Aldrete: And at the same time, just in one single year, let's take for example 2021, we had over 340,000 people crossing the border every day, pedestrians or by vehicle.
• 4:37
  Rafael Aldrete: That's in both directions.
• 4:39
  Rafael Aldrete: So it's a, a staggering amount.
• 4:41
  Rafael Aldrete: Also, I think the other part that gets lost, this trade with Mexico is not only important for the border states, for California, New Mexico, Arizona, and of course Texas.
• 4:51
  Rafael Aldrete: This is very important for states across the union.
• 4:55
  Rafael Aldrete: So you have states all over every single state trades to some extent, and jobs in that state from trade with Mexico are not the same on the Mexican side.
• 5:04
  Rafael Aldrete: Almost every Mexican state depends in one way or another on this trade relationship.
• 5:09
  Bernie Fette: And I think you're getting closer to the next thing I wanted to ask about, which is if you would help us understand on a micro scale, for the typical American citizen or the typical American family in terms of consumer products that we need and any other meaningful metrics, why is the border so important at that personal level?
• 5:30
  Rafael Aldrete: Well, the supply chains that allow us to access all the goods in the big warehouses or that we buy in the grocery store, all, all of that depends on a long chain of transportation and logistics networks that cross the border.
• 5:48
  Rafael Aldrete: So from all the steps that take from the production to the consumption of those products, crossing the border is one of the most complex parts of the, the trip.
• 5:58
  Rafael Aldrete: And it's not only one of the most complex, but it's a process where, you know, some amount of delay and cost in the transportation takes place.
• 6:07
  Rafael Aldrete: Mm-hmm.
• 6:07
  Rafael Aldrete: So anything that disrupts that supply chain is going to result by default in, in a change in the prices, a delay would result in an increased price.
• 6:17
  Rafael Aldrete: Right.
• 6:17
  Rafael Aldrete: For consumer goods, it impacts everything that we buy from vehicles to avocados.
• 6:24
  Rafael Aldrete: So the impact is felt in terms of dollars and prices.
• 6:27
  Rafael Aldrete: So especially in circumstances where price increases are being, uh, something that has been talked about a lot.
• 6:33
  Bernie Fette: With all the news about inflation rates in recent months.
• 6:36
  Bernie Fette: And so what I think I hear you saying is that what happens in a relatively isolated space on the border can have ramifications for what people pay for televisions way up in Wisconsin.
• 6:49
  Rafael Aldrete: Everywhere.
• 6:50
  Rafael Aldrete: That's right.
• 6:51
  Rafael Aldrete: Okay.
• 6:53
  Rafael Aldrete: Your work covers a lot of different aspects and we could easily spend a few hours on talking about all of it, but if we could focus on just a few areas for our visit.
• 7:05
  Rafael Aldrete: One that quickly comes to mind for me is your work in measuring border crossing wait times and how to reduce delays associated with those crossings.
• 7:13
  Rafael Aldrete: Can you tell us a little about what you've been doing on that front?
• 7:18
  Rafael Aldrete: Well, yeah, like you say, this demand that I spoke about, all these people who daily commute across the border, all these trucks that commute across the border delivering goods and services in either side, this demand has often overwhelmed the port of entry system, the border crossings, which in turn gets translated into higher costs.
• 7:39
  Rafael Aldrete: So having a good understanding of what those border crossing times are, knowing what they are occurring at what moment are they taking place when the system gets stressed, is very important for the shippers who are sending their products across the border.
• 7:55
  Rafael Aldrete: It's very important for the individuals who cross the border.
• 7:57
  Rafael Aldrete: So since the opening of the TTI presence here in El Paso with the Center for International Intelligent Transportation Research, we've been looking at ways of estimating and communicating to the traveling public those crossing times.
• 8:13
  Rafael Aldrete: So a big part of the work that TTI my colleagues at TTI have done since 2008, has included developing technologies that allow us to measure in an objective way in real time border crossing times and communicate those crossing times to the public.
• 8:30
  Rafael Aldrete: We started when there were no reliable systems to measure border crossing times anywhere along the border.
• 8:35
  Rafael Aldrete: We started with some pilots here in El Paso using technology that was identified by our researchers at TTI, and that pilot ended up working very well.
• 8:45
  Rafael Aldrete: So the pilot was adopted for implementation in other ports of entry along the Texas Mexico border first.
• 8:53
  Rafael Aldrete: Mm-hmm.
• 8:53
  Rafael Aldrete: .
• 8:53
  Rafael Aldrete: So after El Paso there, other locations in Laredo and the Rio Grande Valley where my colleagues have been implementing the same systems.
• 9:02
  Rafael Aldrete: Not only that, then other states started to request having the same system.
• 9:06
  Rafael Aldrete: So all these systems that we have been deploying, we have been working jointly with the Texas Department Transportation, TxDOT, and with the Federal Highway Administration, FHWA, in making happen after we conducted, you know, some of the pilots here, part of it was funded by TTI right through our Center, and then the bulk of the funding later on came from the Federal Highway Administration and from Texas.
• 9:30
  Rafael Aldrete: Now TTI is operating for these agencies, the system from Brownsville all the way to Otay Mesa, where TTI is working with departments of transportation in California, Arizona, and New Mexico.
• 9:43
  Bernie Fette: So almost that entire 2,000 mile stretch.
• 9:46
  Rafael Aldrete: Correct.
• 9:47
  Rafael Aldrete: Mm-hmm.
• 9:47
  Rafael Aldrete: And now TTI is assisting TxDOT in expanding that system to other ports of entry in Texas where the system is not deployed yet.
• 9:55
  Bernie Fette: And the system that you're talking about that estimates crossing wait times and then communicates those estimates to travelers, to shippers.
• 10:04
  Bernie Fette: Help us understand why that's so important.
• 10:07
  Bernie Fette: I take it at least part of it is that it helps them in planning their shipments, and can you maybe elaborate on that just a bit?
• 10:13
  Rafael Aldrete: Yeah, that's correct.
• 10:14
  Rafael Aldrete: So when you look at the border community on both the Mexican and the US side, very often what you have is several international crossings.
• 10:24
  Rafael Aldrete: There's not only one, right?
• 10:26
  Rafael Aldrete: So it's difficult sometimes for those crossings to cope with the demand and then ensure, for example, that customs has enough officers manning the customs booths to enter the country.
• 10:38
  Rafael Aldrete: So what if you don't have information about what is the level of congestion in one of the ports of entry, it becomes very difficult to make good decisions because all of a sudden what you may see is you may be overwhelming one of those border crossings when there may be more capacity to cross in a different border crossing, which may just be a few miles away.
• 11:00
  Rafael Aldrete: So the intention of the system is to provide information for shippers so that they can know in advance of the truck leaving the departure point, they know which border crossing is likely to provide the fastest way of crossing the border.
• 11:16
  Rafael Aldrete: So it's very important because it ends up, uh, helping make good decisions not only for shippers or for commuters, but it also helps the agencies at the port of entry like Customs and Border Protection to understand what the demand is on each particular port and help them make decisions to deploy less or more customs officers so that they can process the cargo faster.
• 11:40
  Bernie Fette: So everyone concerned can see a benefit here, it sounds like if they have better information on all of the different conditions along that several hundred mile stretch, then you can distribute the demand, distribute the number of vehicles crossing across the full range of crossing facilities, right?
• 12:00
  Rafael Aldrete: Yeah, that's one of the benefits.
• 12:01
  Rafael Aldrete: The other big benefit too is that if you don't have good data, if you don't have objective data that allows you to make an argument to make more investments for new infrastructure or additional capacity at the border, you really have nothing to make that argument.
• 12:15
  Rafael Aldrete: Right?
• 12:16
  Rafael Aldrete: So the other benefit of this information is that once you have compounded historical information enough of it, you can use that information to document what is the cost of delay that is being added to the goods that are crossing the border.
• 12:30
  Rafael Aldrete: What is the inconvenience for fleet operators and therefore what the potential impact is on the cost of the goods that are being shipped across the border zone.
• 12:38
  Bernie Fette: So you're looking at the economics there, and I know that it's also in those border crossing wait times that we typically see the overlap, the intersection, I guess, in sometimes conflict of sorts between efficiency and security or speed of crossing and security, which sounds like a very delicate balancing act.
• 12:58
  Bernie Fette: How do you approach striking that balance between security and efficiency?
• 13:03
  Rafael Aldrete: Yes.
• 13:03
  Rafael Aldrete: So that's also extremely important.
• 13:05
  Rafael Aldrete: The primary mission of Customs and Border Protection, which is part of the US Department of Homeland Security, is to protect the border.
• 13:14
  Rafael Aldrete: But are also charged with the very important task of facilitating trade.
• 13:18
  Rafael Aldrete: So it is, like you say, a balancing act where you need to ensure that freight is moving while at the same time making sure that that freight that is crossing the border is free of contraband or drugs and other things that you don't want crossing the border.
• 13:34
  Rafael Aldrete: And basically it involves a very delicate operation that includes risk analysis, the use of x-ray machines and other techniques to, to ensure that the cargo is safe.
• 13:45
  Rafael Aldrete: So for that same reason, having a better idea of where the demand is, where the delays are, allows you to better deploy, say additional infrastructure that you can use for scanning the trucks that are crossing the border.
• 13:59
  Rafael Aldrete: It also allows you to better deploy officers in those places where there is more demand.
• 14:05
  Rafael Aldrete: So the intersection of facilitating trade and maintaining it, keeping it secure is also one of the beneficiaries I think, of having additional information.
• 14:14
  Rafael Aldrete: It provides additional visibility for border agencies like CBP to understand what is coming at them at the port so they can better accomplish that mission.
• 14:23
  Bernie Fette: Which brings us back to the whole objective of trying to get more accurate border crossing wait time estimates.
• 14:30
  Rafael Aldrete: Yes, that's right.
• 14:32
  Bernie Fette: In discussions about the future of transportation, seems that topics like automated vehicles get a lot of attention in such discussions in part because of the amazing things that artificial intelligence can enable.
• 14:48
  Bernie Fette: But you're using artificial intelligence for other applications specifically to improve border transportation.
• 14:55
  Bernie Fette: Can you give us a sense of what you're doing there?
• 14:58
  Rafael Aldrete: Yeah.
• 14:58
  Rafael Aldrete: So we are taking advantage of artificial intelligence in many ways when looking at having a better understanding how traffic moves across the border and how we can make it more efficient.
• 15:07
  Rafael Aldrete: So we have several examples of that.
• 15:10
  Rafael Aldrete: One of them is we have been using a combination of satellite and aerial imagery with artificial intelligence to understand how traffic moves in those occasions when we have, due to manmade or natural events, the queues grow extreme.
• 15:29
  Rafael Aldrete: Basically, you know, when you have queues that reach five miles of length, we have had instances of that happening over the last four or five years.
• 15:37
  Rafael Aldrete: Different political or natural events have taken place where the throughput across the border has decreased significantly, creating what we call extreme border queues.
• 15:51
  Rafael Aldrete: So when that happens, the, the hardware that we have deployed to estimate those crossing times is insufficient because we cannot cover five miles.
• 15:59
  Rafael Aldrete: Then you need other tools.
• 16:00
  Rafael Aldrete: So we started researching the application of satellite imagery, a high-resolution satellite imagery for that purpose with advances in satellite imagery.
• 16:10
  Rafael Aldrete: Now, we are at the stage where it is easier to get those images in a relatively short amount of time, where you can actually take action by looking at those images.
• 16:19
  Rafael Aldrete: But even with the high-resolution satellite images that are available by commercial satellite providers, I'm talking about a resolution where each pixel in an image is 50 centimeters.
• 16:31
  Rafael Aldrete: So that will be, you know, about less than two feet.
• 16:34
  Rafael Aldrete: So each pixel represents two feet.
• 16:36
  Rafael Aldrete: That resolution is still not good enough for identifying an individual vehicle.
• 16:41
  Bernie Fette: It's a good start, but it's not really what you need.
• 16:43
  Rafael Aldrete: Exactly.
• 16:45
  Rafael Aldrete: So what we are doing is we're using artificial intelligence to enhance those images and therefore increasing the resolution of those images.
• 16:53
  Rafael Aldrete: Once we have been able to increase that resolution, then we can also run artificial intelligence algorithms to identify the vehicles and identify how fast they are moving in a queue.
• 17:03
  Bernie Fette: Right.
• 17:04
  Bernie Fette: It sounds like you're creating a simulation of sorts between the use of the satellite imagery and your artificial intelligence applications.
• 17:12
  Rafael Aldrete: Well, rather than a simulation, what we are using is we're taking advantage of artificial intelligence to process much faster the information than you would by having somebody trying to do it manually.
• 17:24
  Rafael Aldrete: You know, these are satellite images that are 25 square kilometers.
• 17:27
  Rafael Aldrete: So they are huge, and if you want to enhance and identify vehicles in that enormous image, in a relatively short amount of time, a human cannot do it.
• 17:38
  Rafael Aldrete: So we are allowing the artificial intelligence first to enhance the image to a degree that is enough so that it can also count the vehicles in the queue.
• 17:46
  Rafael Aldrete: Okay.
• 17:47
  Rafael Aldrete: If we have an extreme queue starting today, we ordered a picture tomorrow, that queue's gonna continue most likely the next day, because we're talking about queues of 18 hours, which you can imagine those are really bad for the cost of goods, right?
• 17:59
  Rafael Aldrete: When you have, uh, an avocado truck that is waiting 18 hours to cross the border, it's having impact because the avacados may not make it fresh, you know, to the shelves.
• 18:08
  Bernie Fette: Right.
• 18:08
  Bernie Fette: You could lose a great deal of time and therefore lose a great deal of money just in the value of the, for instance, produce that you're shipping across.
• 18:17
  Rafael Aldrete: That is correct.
• 18:18
  Rafael Aldrete: And so the important part here is that it's not so much that today we cannot do it in real time.
• 18:23
  Rafael Aldrete: It is that very soon we will be able to do it in real time and we will have the tools to do it.
• 18:27
  Rafael Aldrete: So right now what we're doing is developing those tools so that tomorrow, in the next couple of years, we're able to actually do that in a much shorter time, maybe in real time.
• 18:37
  Bernie Fette: You're developing the tools now and you're just waiting for the technology to catch up.
• 18:41
  Rafael Aldrete: Exactly.
• 18:43
  Bernie Fette: I know that from conversations we've had before, that border operations involve a pretty wide range of institutions, government agencies, public and private sectors, uh, state, local, federal government on both sides of the border.
• 18:59
  Bernie Fette: And of course, you've got myriad cultural differences that come into play as well.
• 19:04
  Bernie Fette: That sounds like an incredibly complicated picture that you and your colleagues have to operate within every day.
• 19:13
  Bernie Fette: I'm curious what you do to manage all of that at once, and maybe you might have an example of just how complex it can get and how you work within that complexity.
• 19:23
  Rafael Aldrete: Yeah, no, it, it is really complex just simply improving the mobility of people and goods in a non-border environment.
• 19:30
  Rafael Aldrete: It's already a very complex area that requires a multidisciplinary approach and, and knowledge of all the stakeholders involved.
• 19:38
  Rafael Aldrete: When you move to a cross-border environment, this complexity gets compounded significantly.
• 19:44
  Rafael Aldrete: So you not only need these multidisciplinary approach, you know, having, uh, engineers, economists, computer scientists, and the traffic engineers, uh, eh, customs specialists.
• 19:55
  Rafael Aldrete: You, you also have the challenge of the cultural dimension of the border, the different cultures on both sides of the border, the international jurisdictions, because whereas in a domestic environment, you have traditional department of transportation, your local governments, and then your federal jurisdictions.
• 20:11
  Rafael Aldrete: In an international border environment, then you have the addition of, uh, Customs and Border Protection and their counterparts on the other side of the border.
• 20:19
  Rafael Aldrete: You also have authorities at the same level, state, local and national level on the other side.
• 20:26
  Rafael Aldrete: So you need to have an understanding of how the transportation system is looked at on both sides of the border, how the border crossing is looked at on both sides of the border.
• 20:35
  Rafael Aldrete: So some of the examples that I could mention of working in that environment, a few years ago, we were involved in a World Bank-funded project with the municipality of Ciudad Juarez, helping them to develop a regulatory plan for freight movement within the city.
• 20:54
  Rafael Aldrete: But being a border city that is next to El Paso, having an understanding of how that system integrates into the US ports of entry was very important of that study.
• 21:04
  Rafael Aldrete: And at the same time, we have to be able to see the problem from two points of view, from the local point of view, the municipality in Ciudad Juarez, but also from the point of view of the international side and how it integrates.
• 21:17
  Rafael Aldrete: Because the same way that that these ports of entry and border crossings are so important for the US side is the mirror image on the Mexican side.
• 21:26
  Rafael Aldrete: So that was a challenge because we had to basically consider both sides of the border and the complexities of that.
• 21:33
  Rafael Aldrete: Another example that I had the opportunity to be a part of was the recent Texas border master plan.
• 21:39
  Rafael Aldrete: I was part of the Border Trade Advisory Committee that was overseeing that study for TxDOT.
• 21:45
  Rafael Aldrete: It was a years-long effort where TxDOT was working with different stakeholders on the US side, but also with the stakeholders on the Mexican side.
• 21:53
  Rafael Aldrete: And whenever we had an opportunity to look at what the study output was being and when we provided feedback into that study, it was very interesting, but at the same time, very rewarding to see that we were able to document such a complex process in conducting this plan along with TxDOT, ensuring that we were looking at both sides of the border in developing that plan and that we had the priorities from agencies on both sides of the border.
• 22:17
  Rafael Aldrete: So anyway, that's another example, too, of how complex it is to develop something, anything, any transportation project in the context of border crossings.
• 22:28
  Bernie Fette: So what you do has a heavy involvement in science of course, but it sounds like it has a pretty significant piece of it that has to do simply with human relations.
• 22:39
  Rafael Aldrete: Yes.
• 22:40
  Rafael Aldrete: Yeah, it's very important.
• 22:41
  Bernie Fette: Where do you think that you and your colleagues have made biggest impact through your work since you've joined TTI?
• 22:48
  Rafael Aldrete: Well, our center here in El Paso, we just considered border crossings or, or activities around the border.
• 22:54
  Rafael Aldrete: I think our biggest contribution has been, and that's by default because of our mission at the center, is to develop those cutting-edge technologies that are going to take us to the next level.
• 23:05
  Rafael Aldrete: So like I mentioned 10 years ago, we started doing some of the basic research that then translated into our colleagues developing, uh, this border crossing information system that provides information on border crossing times using Bluetooth and wifi technology.
• 23:21
  Rafael Aldrete: So it was Center-funded research that conducted the first tests to understand the visibility of using that technology to conduct it here.
• 23:29
  Rafael Aldrete: Then later on, we have developed other technology that is based, I gave you a couple of examples of artificial intelligence, but we have done others also aimed that solving challenges that we've identified in terms of being able to get the information you want and that you need in order to make border crossing transportation more efficient.
• 23:48
  Rafael Aldrete: Just to give you an example, when you're looking at something that may seem as basic as obtaining real-time counts of vehicle crossing the border, five years ago, there was no commercial product available in the traffic hardware market that would allow you to do that.
• 24:04
  Rafael Aldrete: Every commercial hardware available, traffic counter available was not designed to operate in conditions that are like a border crossing where you have stop-and-go traffic with significant amounts of traffic with trucks that are standing in a single spot for many minutes.
• 24:21
  Rafael Aldrete: So what we did over five years, we tested pretty much any commercial traffic counter in the market at the border crossings, and none of them worked.
• 24:31
  Rafael Aldrete: So we ended up developing our own.
• 24:33
  Rafael Aldrete: Our researchers successfully developed a vehicle counter that uses LIDAR technology.
• 24:39
  Rafael Aldrete: It's basically light-based technology to count the vehicles that across the board with we are talking about precisions of 99.5 percent of the actual volumes.
• 24:50
  Bernie Fette: Far better than the human counters that probably handled that task in the past.
• 24:54
  Rafael Aldrete: Right, exactly.
• 24:56
  Rafael Aldrete: That's actually one of the findings.
• 24:57
  Rafael Aldrete: So we have now deployed several of those counters here in the El Paso region, and now what we are doing, again, using artificial intelligence is combining the crossing times that we are producing with those volume counts and with other information to provide what we call a short-term forecast of border crossings.
• 25:16
  Rafael Aldrete: So we developed the technology not only to count the vehicles, we also developing the technology to provide a short-term forecast, which is very important when you're looking at border crossings because the information that we currently, normally you would have access to in a border crossing information system, it's a little bit delayed, which doesn't give you the exact time is gonna take you if you're starting your trip now.
• 25:40
  Rafael Aldrete: So what we did using this LIDAR technology and artificial intelligence, we were able to produce a short-term forecast that allows us to say vehicle data just joined the queue.
• 25:53
  Rafael Aldrete: It's gonna take you this many minutes to cross.
• 25:56
  Rafael Aldrete: So the information is more current.
• 25:59
  Bernie Fette: Very important, whether you're shipping televisions or especially if you're shipping pineapple and bananas.
• 26:05
  Rafael Aldrete: Yes.
• 26:06
  Rafael Aldrete: Uh, huh.
• 26:08
  Bernie Fette: Okay.
• 26:08
  Bernie Fette: You've been at TTI for about 15 years?
• 26:11
  Bernie Fette: A little more than 15 years.
• 26:12
  Rafael Aldrete: Yes.
• 26:13
  Rafael Aldrete: 16
• 26:14
  Bernie Fette: Years.
• 26:14
  Bernie Fette: Okay.
• 26:14
  Bernie Fette: 16 years.
• 26:15
  Bernie Fette: And you've been studying border transportation issues for that entire time, along with other things, of course.
• 26:20
  Bernie Fette: What's the biggest change that you have seen on the border in the time that you've been doing this work?
• 26:29
  Rafael Aldrete: I think that what has changed the most since we started working here has been the degree of cooperation that stakeholders on both sides of the borders have.
• 26:39
  Rafael Aldrete: That level of cooperation has increased significantly.
• 26:43
  Rafael Aldrete: So that has allowed some things that were, I think about 15 years ago to start happening.
• 26:48
  Rafael Aldrete: Some of them, I would say, for example, uh, well of course the border crossing times, right?
• 26:53
  Rafael Aldrete: That was one thing that didn't exist before.
• 26:56
  Rafael Aldrete: But also the concept of pre-inspection that now Customs and Border Protection is able to conduct inspections of shipments on the Mexican side in some locations so that the trucks don't have to stop at the border.
• 27:09
  Rafael Aldrete: That is already happening in Laredo, but here in Santa Teresa on the New Mexico border, that's happening.
• 27:15
  Rafael Aldrete: So that's a huge change, and the way it directly impacts the border crossing time because then you don't have those trucks that are getting inspected.
• 27:23
  Rafael Aldrete: Those for sure are not stopping at the border for a long time.
• 27:26
  Rafael Aldrete: So that's a big change, and it involves the cooperation of all the stakeholders, federal, state, and local, and national, international.
• 27:33
  Bernie Fette: So you're bringing it back to the stakeholder change.
• 27:36
  Rafael Aldrete: To the people factor.
• 27:36
  Bernie Fette: Mm-hmm.
• 27:37
  Bernie Fette: , the people factor, and I wonder what it was that motivated that change for those stakeholders to improve their interagency relationships and their interagency workings over those years?
• 27:50
  Bernie Fette: Well, I'll just ask you, what do you think brought that about?
• 27:53
  Rafael Aldrete: Well, I think it's been a push and a pull.
• 27:55
  Rafael Aldrete: The push has been from the local agencies that are, you know, the, let's say your municipalities, your bridge owners, the people who are closer to those individuals who drive across border on a day-to-day basis, the shippers, the traveling public, the bridge operators, they've been pushing for improving cross border cooperation to improve cross-border times because they feel the impact immediately.
• 28:21
  Rafael Aldrete: Mm-hmm.
• 28:21
  Rafael Aldrete: , and then the pull also the microscopic trend of increasing trade relationship between Mexico and the US.
• 28:28
  Rafael Aldrete: The amount of trade that has been increasing, and that has been the two things, have made this possible, this increasing cooperation, because there are rewards on both sides.
• 28:37
  Rafael Aldrete: So at the same time, there have been stakeholders and the federal government have developed ways that allow local communities to now directly cooperate with, say for example, Customs and Border Protection by helping pay for overtime of customs officers so they can expand the hours of operation and help open the border crossings for more hours or add more officers at big times and so on.
• 29:00
  Rafael Aldrete: So that's been made possible because trade is important for the entire nation, but also you have the local perspective of those individuals who get directly impacted by those border delays every day.
• 29:11
  Bernie Fette: At the risk of oversimplifying, it sounds like part of the reason is that the many, many stakeholder groups have clearly just started to see more obviously, that there's something for each party to gain here.
• 29:25
  Rafael Aldrete: Yes.
• 29:25
  Rafael Aldrete: And especially now.
• 29:26
  Rafael Aldrete: Bernie, you know, I don't know if you've heard of the term near-shoring and friend-shoring.
• 29:31
  Bernie Fette: Yes.
• 29:31
  Bernie Fette: Yes.
• 29:32
  Rafael Aldrete: As a result of the COVID 19 pandemic, we all know that the supply chains reconfigure significantly, and they are continuing to reconfigure.
• 29:40
  Rafael Aldrete: And so now you're having a lot of companies that are looking at reshoring, bringing back some of the production to the US, the manufacturing or bringing it nearby, like, you know, say for example, Mexico or Canada.
• 29:53
  Bernie Fette: When you say moving it, we're talking about moving it primarily from China, from
• 29:56
  Rafael Aldrete: Asia, from China, from
• 29:57
  Bernie Fette: Asia, closer to home.
• 29:59
  Rafael Aldrete: Closer to home, so that, uh, when you have a disruption, you know, it's easier to deal with it in the future.
• 30:05
  Rafael Aldrete: They're also using the term friend-shoring for that specific purpose because you, you want to make sure you're trading with friends.
• 30:11
  Rafael Aldrete: That's also another term that is being used, but at the end, it's the same, the same reason.
• 30:14
  Rafael Aldrete: There is a lot of manufacturing that is moving back to the US and to the vicinity of the US including Mexico, and that only means one thing, that this trade is going to continue growing and it's probably gonna grow at a faster pace.
• 30:28
  Bernie Fette: Hmm.
• 30:28
  Bernie Fette: Also, in reference to your 16-year tenure that we were just talking about, I'll ask you what I ask in each of the conversations that we have with our guests.
• 30:38
  Bernie Fette: What is it more than anything else that makes you excited to come to work every day?
• 30:46
  Rafael Aldrete: What excites me the most about my job really is the ability to work on something different every day in a new challenge and learning and using new tools, new concepts every day.
• 30:58
  Rafael Aldrete: The challenge that that brings is just a challenge that keeps you very interested and engaged and, and working with the people that I work with here.
• 31:05
  Rafael Aldrete: That's also something that makes me want to come to the office every day, especially during the COVID time.
• 31:10
  Rafael Aldrete: I was missing being in the office, but I think now you know where things are returning to a more normal or new normal, and being able to discuss, to exchange ideas with my colleagues here and with sponsors.
• 31:23
  Rafael Aldrete: I think that's really one of the things that keeps me engaged.
• 31:26
  Bernie Fette: Certainly a good thing that you enjoy challenges because you most certainly do not have a shortage of them, it seems.
• 31:34
  Rafael Aldrete: Thank you.
• 31:35
  Rafael Aldrete: Yeah.
• 31:36
  Bernie Fette: Rafael Aldrete, senior research scientist for TTI and Director of the Center for International Intelligent Transportation Research.
• 31:47
  Bernie Fette: Rafa, thank you so much for your time.
• 31:48
  Bernie Fette: We're really fortunate to have you on our team.
• 31:51
  Rafael Aldrete: Thank you, Bernie.
• 31:51
  Rafael Aldrete: It was my pleasure.
• 31:52
  Rafael Aldrete: I appreciate the invitation.
• 31:56
  Bernie Fette: In discussions and news reports about the US-Mexico border, immigration tends to be the central topic, but there's a huge amount of activity at those land ports of entry that has little to do with people crossing in either direction.
• 32:11
  Bernie Fette: Trade between the two nations, imports and exports combined, totals more than$660 billion each year.
• 32:20
  Bernie Fette: Cross-border commercial activity is central to the health of both countries on an enormous scale.
• 32:28
  Bernie Fette: And on a more personal scale, too, because what happens along those international entry points can influence what we pay for everything from avocados to televisions.
• 32:42
  Bernie Fette: Thanks for listening.
• 32:44
  Bernie Fette: Next time, we'll visit with TTI's Beverly Kuhn and Jeff Paniati, the outgoing president and the current CEO of the Institute of Transportation Engineers.
• 32:56
  Bernie Fette: We hope you'll take time to join us for that conversation, and that you'll take time also to give us a review, subscribe, and share this episode, Thinking Transportation is a production of the Texas A&M Transportation Institute, a member of the Texas A&M University System.
• 33:16
  Bernie Fette: The show is edited and produced by Chris Pourteau.
