Latest / Thinking Transportation: Engaging Conversations about Transportation Innovations / Uncommonly Deadly: Wrong-way crashes are small in number, immense in devastation.
Transcript
- 0:14Bernie Fette (host): Hello.
- 0:15Bernie Fette (host): This is Thinking Transportation-- conversations about how we get ourselves and the things we need from one place to another and what may happen along the way.
- 0:27Bernie Fette (host): I'm Bernie Fette with the Texas A&M Transportation Institute.
- 0:32Bernie Fette (host): Wrong way driving occurs on all types of roadways.
- 0:35Bernie Fette (host): Wrong way crashes are somewhat rare, but when they happen on high speed freeway exit and entrance ramps, those collisions are almost always serious or fatal.
- 0:48Bernie Fette (host): More than 200 instances of wrong way driving are reported on Texas freeways every year.
- 0:55Bernie Fette (host): Most of them involving a driver who's impaired.
- 0:59Bernie Fette (host): Understanding those crashes and figuring out how to prevent them is the focus of one team's work at TTI, led by Melisa Finley, a senior research engineer at the agency.
- 1:12Bernie Fette (host): I know you've been super busy, Melisa.
- 1:14Bernie Fette (host): There have been a number of things getting in the way of us getting this scheduled, so thanks so much for taking time to join us.
- 1:20Melisa Finley (guest): Sure.
- 1:20Bernie Fette: And if we can, Melisa, let's begin by trying to frame this issue of wrong way driving.
- 1:28Bernie Fette: What is it exactly and how widespread is it?
- 1:33Melisa Finley: So when we talk about wrong way driving, we're talking about people that either intentionally or unintentionally end up going in the wrong direction of travel.
- 1:42Melisa Finley: So this can be from confusion, it can be caused by geometry, it can be caused by other behaviors.
- 1:49Melisa Finley: But yes, we definitely want to define it as someone going in the opposite direction of the normal cars on the roadway.
- 1:57Bernie Fette: And that could be the wrong way up a one way street, I guess technically, but you focus on something a little more narrow.
- 2:04Melisa Finley: We do.
- 2:05Melisa Finley: A lot of times wrong way driving is focused on freeways or what we call limited access roadways, where we just have exit and entrance ramps because those are higher speed and unfortunately those crashes tend to be fatal.
- 2:19Melisa Finley: But wrong way driving happens on all types of roadways from city streets to divided highways all the way up to freeways.
- 2:27Bernie Fette: Okay.
- 2:28Bernie Fette: And can you talk about how widespread it is?
- 2:30Bernie Fette: I mean, how many of these incidents do we typically have in Texas and elsewhere in a given year?
- 2:35Melisa Finley: So for many years we were running between about three and 400 wrong way driving crashes a year in Texas we did top over 400 in 2021.
- 2:46Melisa Finley: We do see coming out of the pandemic time period, a lot more risky behavior across the board.
- 2:51Melisa Finley: And we're obviously seeing that in wrong way of driving incidents as well.
- 2:56Melisa Finley: But we do remain less than 1 percent of the overall crashes that happen in Texas.
- 3:01Melisa Finley: So it's a small number, but as I mentioned, a lot of those crashes end up being fatalities because they happen on high speed roadways where you have two vehicles coming together typically head on.
- 3:13Bernie Fette: Right.
- 3:13Bernie Fette: And do you have a sense of how common the problem is beyond Texas?
- 3:18Bernie Fette: I know Texas is your focus.
- 3:20Melisa Finley: It happens everywhere.
- 3:21Melisa Finley: We know in all states we have some wrong way driving crashes.
- 3:24Melisa Finley: A lot of times in the bigger states that have more lane miles, you're gonna see a higher number of wrong way driving crashes than others.
- 3:30Melisa Finley: But it does happen everywhere.
- 3:32Melisa Finley: It just also depends on the types of facilities those states have.
- 3:35Melisa Finley: You know, some smaller states have less highway miles, maybe it's more urban streets, but again, they're, they're happening everywhere and our crashes show that.
- 3:43Melisa Finley: But again, a lot of the focus to date from the research standpoint has been on freeways or those high speed divided roadways.
- 3:51Bernie Fette: And how are the numbers trending?
- 3:53Bernie Fette: Are they getting worse staying about the same?
- 3:56Melisa Finley: Percentage wise?
- 3:57Melisa Finley: I'd say they're staying about the same.
- 3:58Melisa Finley: If you just look at raw numbers, you may be seeing some increases.
- 4:01Melisa Finley: But when we factor in things like vehicle miles traveled and volume and we look at the overall crash picture, they're staying, I would say at least Texas, they're staying about the same percentage of the overall number of crashes.
- 4:13Bernie Fette: Okay.
- 4:14Bernie Fette: I'm guessing that there are some people, and I certainly count myself in this group, who are at least somewhat surprised by the extent of this problem, a little surprised that any driver could find a way to come up the wrong way on a freeway exit ramp, given all the warning signs-- wrong way, do not enter-- these big red sign.
- 4:36Bernie Fette: Many of them lighted.
- 4:37Bernie Fette: They almost seemed to scream out at people coming in that wrong direction.
- 4:42Bernie Fette: Not to mention the fact that it's so nonsensical.
- 4:45Bernie Fette: And I can certainly admit that there have been times when I was in a very unfamiliar downtown in another city and for a block or so went the wrong way down a one way street scares the heck out of a person.
- 4:56Bernie Fette: But can you help us understand why this happens?
- 5:00Melisa Finley: Yeah.
- 5:00Melisa Finley: So let me just point out, it's interesting when I do presentations on wrong way driving, one of my first kind of things I always ask the room is how many people have seen a wrong way driver?
- 5:09Melisa Finley: And you'd be surprised that at least more than half the majority of the time raise their hand.
- 5:14Melisa Finley: Yeah.
- 5:14Melisa Finley: So something that we know is the crashes are small, but we know the events happen a lot more than translate into crashes, which is good.
- 5:22Melisa Finley: But we still know that the problem really as we define it typically with crashes, is underestimated when we start looking at the number of events and you talk to people and you start looking at some other types of data besides crashes.
- 5:35Melisa Finley: And so I always like to ask that question and everybody kinda looks around the room surprised right.
- 5:39Melisa Finley: That that many people have seen wrong way drivers.
- 5:41Bernie Fette: Do you also ask, okay, now that I've answered that question, how many of you have actually done this?
- 5:47Melisa Finley: I do.
- 5:48Melisa Finley: I ask that question too.
- 5:49Melisa Finley: And usually it's a smaller percentage, but I have to raise my hand for both.
- 5:53Melisa Finley: Okay.
- 5:53Melisa Finley: I like you have gotten confused on a small collector, you know, street in an urban urban area where you're not familiar, but there's a lot of cues there.
- 6:00Melisa Finley: Right?
- 6:00Melisa Finley: As soon as you turn, there's cars maybe parked facing you, there's one way signs, there's, you know, some vehicles coming maybe at you at a very low speed.
- 6:08Melisa Finley: You can kind of put your hand up and be like, wait a second.
- 6:11Melisa Finley: And you do your three point turn and you kind of get out of the way.
- 6:14Melisa Finley: Yeah.
- 6:14Melisa Finley: Um, that's not as easily corrected or as recognized sometimes on high speed roadways.
- 6:19Melisa Finley: Especially because a lot of these types of events do happen at night where we have less visual cues to be able to tell us that we're going in the wrong direction.
- 6:29Melisa Finley: And then we also have impairment that comes into play with wrong way driving.
- 6:33Melisa Finley: And so, you know, you mentioned signs, pavement markings at our exit ramps.
- 6:38Melisa Finley: Those are there to help tell a driver that they're going the wrong way, especially if they accidentally get confused because they're an unfamiliar motorist.
- 6:46Melisa Finley: But sometimes those traditional low cost signs and pavement markings do not catch the attention of someone maybe that's impaired, and it can be impaired from alcohol or some kind of drug, but it can also be an impairment from a medical condition.
- 7:02Melisa Finley: Mm-hmm.
- 7:02Melisa Finley: , We've seen those before in the data where someone is just confused cuz maybe they're in diabetic shock or there's some other reason why their body is not functioning normally and they may not realize that.
- 7:13Melisa Finley: And so there's a variety of reasons that you may be impaired and not make a correct decision and turn the wrong way.
- 7:20Bernie Fette: Okay.
- 7:20Bernie Fette: You mentioned impairment, you mentioned a lot of these happen at night when our vision might not be as sharp and reliable as it is in broad daylight.
- 7:30Bernie Fette: I was waiting for you to mention another factor that I was kind of curious about and that was age.
- 7:35Bernie Fette: Does age factor into your data very much?
- 7:38Melisa Finley: It does.
- 7:39Melisa Finley: Age does factor in.
- 7:40Melisa Finley: So we do see, compare to some other types of crashes.
- 7:44Melisa Finley: In some states we do see an over representation of older adults depending on the years you look at in Texas, sometimes that's held true, sometimes it hasn't.
- 7:53Melisa Finley: But we do want to make sure that we're looking at older adults when we're talking about this issue.
- 7:58Melisa Finley: A lot of times what we see is those tend to be more of the daytime crashes.
- 8:03Melisa Finley: You know, a lot of older adults already regulate themselves maybe to stop driving at night so they're not as a big a proportion of those types of crashes at night.
- 8:11Melisa Finley: But during the day we do see some confusion and some of those can be overrepresented with an elderly population.
- 8:18Melisa Finley: Just being aware of when it might be your time to stop driving or if you're a a child of an elderly adult, just to have those candid conversations and to watch so that they don't become confused.
- 8:28Melisa Finley: You know?
- 8:29Melisa Finley: Cuz that's usually what happens.
- 8:31Melisa Finley: I have witnessed four wrong way drivers since I've started studying this
- 8:36Bernie Fette: Just, just not doing research.
- 8:38Melisa Finley: Not doing research.
- 8:39Bernie Fette: You were just, you were just out driving and this is what you saw.
- 8:42Melisa Finley: Just, just out driving of which several have been on city streets here in the Bryan- College Station area where we're located and a couple of those have been apparently elderly drivers, but it's like a boulevard, a divided roadway where they've just turned from a signal maybe into the wrong side of the roadway fairly quickly self-correct.
- 8:59Melisa Finley: But those are common.
- 9:00Melisa Finley: Yeah.
- 9:01Bernie Fette: I'm curious about what it was that prompted you and your colleagues to start focusing on this, which I know you've been doing for a number of years now, but somewhere along the line, I wonder if someone or some agency just decided that this was a big enough problem to warrant some research.
- 9:17Melisa Finley: So as I mentioned before, the crash data, you know, it's really random and it's really rare.
- 9:23Melisa Finley: So when you start looking at this data, there's, you have to look at a large sample of years.
- 9:28Melisa Finley: They again can be very horrific kind of crashes, right?
- 9:33Melisa Finley: And newsworthy.
- 9:33Melisa Finley: And so a lot of times it just happens that if one happens and there's news around it, we just started seeing it coming up more and more.
- 9:42Melisa Finley: And then a lot of times what happens in a local area is someone will end up in a crash.
- 9:49Melisa Finley: For instance, in San Antonio, it was a police person.
- 9:52Melisa Finley: Mm-hmm.
- 9:52Melisa Finley: .
- 9:52Melisa Finley: So there was a police lady there in San Antonio that ended up in a wrong way crash.
- 9:57Melisa Finley: And that kind of elevated it.
- 9:58Melisa Finley: Not to say that other people shouldn't be worthy of it being elevated, but sometimes it takes that one special kind of crash for it to elevate in a community to where people start digging into the data, start looking at the issue, and as we look past crashes and start looking at events, we can start to see more of a trend of maybe where they're happening, how they're happening, and then dive into the reasons and start to look at how to circumvent those from happening.
- 10:24Bernie Fette: And on the subject of circumventing them, can you walk us through the progression of solutions that you and your team have come up with over the years, some of the earliest counter measures and how those might have led to other more current ideas that you've put into use?
- 10:40Melisa Finley: Yeah, I think the first thing for everyone to know is it's just really important if you are a transportation agency, just to check what you have out there.
- 10:48Melisa Finley: Obviously we use signs and pavement markings, they're a critical piece on how we talk to the drivers and they have to be maintained, right?
- 10:55Melisa Finley: So just making sure that your signs are still retroreflective, your payment markings are retroreflective, everything's present.
- 11:01Melisa Finley: You know, things do get knocked down and need to be maintained.
- 11:05Bernie Fette: I have to stop you just for a moment there whenever you said retroreflective.
- 11:08Bernie Fette: What's the difference between simply reflective and retroreflective for our non-engineers in the audience?
- 11:15Melisa Finley: No, great question.
- 11:16Melisa Finley: So reflective just means like a standard surface.
- 11:19Melisa Finley: Think of a paint wall, we're gonna get some reflection of light off that wall, but if you were to turn off the lights and just hold a candle, you still aren't gonna be able to necessarily see that wall and it's not gonna stand out.
- 11:29Melisa Finley: When we're retroreflective, we put special materials inside pavement markings and signs so that your headlights on your car actually retro reflect, which means they bounce off the sign and come back to your eyes of the driver so that you can read or see that device instead of the lights scattering like it would on a more diffused surface, like say the the wall.
- 11:50Bernie Fette: And those are the treatments that every typical sign on the freeways get before they go up in their placement, right?
- 11:57Melisa Finley: That's correct.
- 11:57Melisa Finley: All signs and pavement markings that are out there on the roadway are retroreflective so that you can see them at night in your vehicle.
- 12:04Bernie Fette: Okay.
- 12:04Bernie Fette: I interrupted you to get that clarification and you were talking about that quality, the retroreflective quality.
- 12:10Bernie Fette: What else were you going to mention about the countermeasures?
- 12:13Melisa Finley: Right, so as we look to more extensive countermeasures, maybe that we are using the data to see areas that may be more prone to wrong way, driving, whether it's because of the geometry of the ramp or maybe the surrounding area environment.
- 12:27Melisa Finley: We want to look at things that we call conspicuity elements, which just the big word for saying we wanna make sure you see this device, this traffic control device.
- 12:36Melisa Finley: So we add an element to draw your attention to that device.
- 12:40Melisa Finley: Those could be beacons, those can be lights embedded in the sign.
- 12:44Melisa Finley: Those can be rapid rectangular flashing beacons that we put above or below the sign.
- 12:50Melisa Finley: And that just draws your attention.
- 12:51Melisa Finley: So if you're driving, we know there's a lot to be looking at, right?
- 12:54Melisa Finley: There's the roadway, you're controlling your vehicle, but say there's a sign, like a wrong way sign that we wanna draw your attention to because you've turned in the incorrect direction, we can use those lights to do that.
- 13:06Melisa Finley: We also put sometimes retroflective striping on the pole so that it just pops more in the in the environment.
- 13:13Bernie Fette: Okay.
- 13:13Melisa Finley: And those types of things are kind of a step up to be able to say, hey, you know what?
- 13:19Melisa Finley: We wanna make sure if somebody turns the right way, we can draw their attention.
- 13:23Melisa Finley: But then you've gotta have someone that can read them, right?
- 13:26Melisa Finley: So if we're in our normal state of driving, a lot of times those kind of systems will help us turn around and we see that a lot.
- 13:32Melisa Finley: So as these systems are installed and transportation agencies have also cameras and devices that kind of coexist with those types of traffic control device systems, we can actually see people turning around and correcting, which is great, right?
- 13:47Melisa Finley: So we know they don't proceed onto the system, but sometimes people, again, are impaired for a variety of reasons and they don't necessarily get to be able to read those signs.
- 14:00Melisa Finley: Mm-hmm.
- 14:00Melisa Finley: .
- 14:00Melisa Finley: Um, so we do use color also, just so you know, if you ever see red on the roadway, on the pavement, if you see a red sign like a do not enter a wrong way sign, that's your first indication as a driver that you're going the wrong way.
- 14:12Melisa Finley: So make sure and look at that color as well.
- 14:16Melisa Finley: But sometimes all those devices aren't interpreted by the driver correctly and they do proceed onto the system the wrong way.
- 14:24Bernie Fette: Yeah.
- 14:25Bernie Fette: And you were talking to the driver there for just a moment.
- 14:27Bernie Fette: I wonder if you could just continue down that path a little bit.
- 14:31Bernie Fette: If a person realizes, oh my gosh, I'm going the wrong way, what should they do?
- 14:37Bernie Fette: You mentioned a three point turn a little while ago that I guess would be great if the traffic isn't moving very fast, but under various conditions, if a driver notices that they are going the wrong way, what should they do?
- 14:52Melisa Finley: Pull over and stop as soon as you can.
- 14:54Melisa Finley: You know, the best thing to do is to try to get out of the path of oncoming traffic as quickly as possible and then as safely as you can, try to turn your vehicle around.
- 15:03Melisa Finley: If you need assistance, call law enforcement.
- 15:06Melisa Finley: Just explain, I got on going the wrong way, I was confused on where I was going.
- 15:10Melisa Finley: I need some assistance out here to safely turn around.
- 15:12Melisa Finley: You know, there's a lot of traffic say on a freeway and you can't make that turn safely.
- 15:16Melisa Finley: I would err on the side of caution and just make sure again, that you pull off and be able to safely correct as soon as possible.
- 15:23Bernie Fette: Okay, great.
- 15:24Bernie Fette: Let's talk a little bit about technology advancements in the area of countermeasures, particularly those that we don't know about yet.
- 15:32Bernie Fette: We hear a lot about the prospect of self-driving cars, and I love the comment that Jeff Paniati made in our last episode, which was"self-driving cars have been five years away for the past 10 years," but they are still on the way-- at least, so we are told.
- 15:50Bernie Fette: And the prospect of self-driving cars is built largely on the promise that they will improve safety.
- 15:55Bernie Fette: How might advancements associated with those autonomous vehicles help to create solutions for the wrong way driving problem, if at all?
- 16:04Bernie Fette: I'm making an assumption there, but is there a potential benefit there?
- 16:08Melisa Finley: Yes, I think there is, and I think there's actually a benefit even as we progress to that endpoint, right?
- 16:14Melisa Finley: So we're putting a lot more sensors on our cars, we're putting a lot more assistance devices on our cars, and I think as we do that, we build in maps, we do other things, we're going to be able to help people more immediately recognize via whether the car just won't let you turn that way or the car gives you some kind of alarm, knowing that you're going in the wrong direction.
- 16:33Melisa Finley: Ultimately, self-driving cars, as long as they realize what the system, how it's supposed to function and the direction of travel, you know, in theory, again, like you said, that will help reduce wrong way driving.
- 16:44Melisa Finley: But we do have to make sure the information fed to those vehicles or the information they obtain from the roadway themselves is correct for that to happen.
- 16:52Melisa Finley: Mm-hmm.
- 16:52Melisa Finley: , you know, we do go in and and change roads temporarily.
- 16:55Melisa Finley: We have to maintain and construct new facilities.
- 16:58Melisa Finley: And so sometimes I'm thinking of construction where we push people onto the other side of the roadway.
- 17:03Melisa Finley: Well, technically I'm on the wrong direction of travel, but it's okay because you physically put me on the other side of the roadway.
- 17:10Melisa Finley: But we're gonna have to think through those kind of things for the car to understand this is an okay situation to be going the wrong way.
- 17:16Melisa Finley: This is not an okay situation to be going the wrong way.
- 17:19Melisa Finley: So I think it's exciting.
- 17:20Melisa Finley: I think it's definitely the way that we'll be able to help those motorists that are confused and other things, and hopefully with those that even though they shouldn't maybe choose to drive impaired, you know, I think at some point in our conversation we wanna make sure and touch on the fact that this does have a driver behavior element to it.
- 17:42Melisa Finley: That we can't solve everything with the vehicle.
- 17:44Melisa Finley: We can't solve everything with the traffic control devices.
- 17:47Melisa Finley: We can't solve everything with the geometry of the roadway drivers.
- 17:52Melisa Finley: At least for right now.
- 17:53Melisa Finley: Like you said, we're not all driving around in automated vehicles yet.
- 17:56Melisa Finley: We have to take some responsibility when we get behind the wheel to try to drive to the best of our ability.
- 18:01Melisa Finley: And that means that if you're impaired, you should choose not to drive.
- 18:05Melisa Finley: So I think that's a big message that we miss a lot of times with wrong way driving.
- 18:09Melisa Finley: A lot of people want to focus on what was or wasn't present at an exit ramp as far as infrastructure, but we have to remember that the driver has some responsibility as well.
- 18:19Bernie Fette: And that very thing is exactly where I was hoping that we could take our conversation next.
- 18:26Bernie Fette: You've made some considerable progress with the countermeasures that you've talked about, but as with any other traffic safety problem, you're somewhat limited in what you can do as an engineer.
- 18:36Bernie Fette: Meaning you can engineer a lot of things that are within your control, or at least within your realm of influence, but you can't engineer human behavior.
- 18:48Bernie Fette: So where do you see this going?
- 18:50Bernie Fette: What might be the next ways to bring the wrong way driving numbers down even farther?
- 18:56Melisa Finley: So I think sometimes, I mean, we've always, as engineers looked at the human factor side of issues, especially when it comes to traffic control device, but also with design, right?
- 19:05Melisa Finley: So there are some historic infrastructure that's out there that as we rebuild and reconstruct, we have to think about ways that we're designing ramps and interchanges to minimize those types of maneuvers so that we can say, hey, how could a human get confused here and how can I mitigate that?
- 19:21Melisa Finley: And we can do the same with traffic control devices, you know, how we place them, how we angle them, how many we put out there.
- 19:27Melisa Finley: But again, like you mentioned, there's only so much we can do as far as engineering to solve this problem.
- 19:33Melisa Finley: And so I think coming in with advanced vehicle information and the driving ability of the car also notifying other drivers is an important piece to this.
- 19:44Melisa Finley: And that will come as we also have more advanced information systems in vehicles, those dynamic message signs that are in locations, but they're fixed, right?
- 19:54Melisa Finley: I don't have a dynamic message sign on every mile of roadway.
- 19:56Melisa Finley: We try to use communication methods that we can, but there's apps, there's abilities to geofence certain areas now.
- 20:04Melisa Finley: So there's ways that we can communicate out to folks as well that are going the right way to let them know there's an issue on the roadway that they're on so they can be more prepared and use caution.
- 20:16Melisa Finley: So I think that's an important piece as well.
- 20:18Melisa Finley: Communication, obviously knowing that the driver is on the system is important.
- 20:23Melisa Finley: So detection, uh, the way we can use infrastructure like cameras or other types of radar, LIDAR, sensors that we have out there at ramps and along the main lanes just to be able to notify us when a wrong way driver is there so that hopefully we can get law enforcement present quick enough to stop that vehicle before it turns into a crash.
- 20:46Bernie Fette: You can't engineer their behavior, but it's obvious that you're doing a lot to at least help them.
- 20:51Melisa Finley: We try to help the driver as much as possible.
- 20:53Melisa Finley: I will mention that there is a small number of wrong way drivers that are intentional, and there's two types of those.
- 21:01Melisa Finley: One type is I just wanna get from A to B in the shortest route, so maybe it's not convenient for me to go down a road and make a U-turn, so I'm just gonna go a couple hundred foot down this road and turn because that's the closest route for me.
- 21:14Melisa Finley: I would just say to drivers, please don't do that.
- 21:17Melisa Finley: You know, that's your choice to do that, but that's a behavior that can lead to something devastating for yourself or someone else's family.
- 21:25Melisa Finley: So take an extra minute, go down, go the correct way.
- 21:29Melisa Finley: We all have time to be safe.
- 21:31Melisa Finley: There is a small segment of those intentional folks that unfortunately have decided that they maybe want to end their life.
- 21:38Melisa Finley: And so we do hear that some with wrong way driving.
- 21:41Melisa Finley: We hear that some with our commercial motor vehicle folks that we interview and talk to about wrong way driving.
- 21:48Melisa Finley: And unfortunately those are again a small segment, but those are ones again that you really can't engineer for, right?
- 21:54Melisa Finley: That's a, that's a choice that they're making, unfortunately.
- 21:57Bernie Fette: Well, and as you said very early in our conversation, these crashes might be rare, but they are almost always severe and fatal.
- 22:04Melisa Finley: Correct.
- 22:05Melisa Finley: And unfortunately, yes.
- 22:07Bernie Fette: What have I not asked you about that you would've liked me to ask you about?
- 22:13Bernie Fette: Any closing thoughts that you'd like to bring together and wrap up?
- 22:17Melisa Finley: It's just important that we realize that if we're all going toward Vision Zero or whatever it is, maybe your transportation agency or state has with respect to fatal and serious crashes, that we have to look at every type of crash and that involves wrong way driving crashes.
- 22:33Melisa Finley: And we have to look at all the types of data that we have available to try to better continue to understand why it's happening, where it's happening.
- 22:41Melisa Finley: But unfortunately, again, it's rare and random.
- 22:43Melisa Finley: And so a lot of folks are always asking, why can't we put a lot of tech devices at every ramp?
- 22:49Melisa Finley: There are thousands of exit ramps alone in the state of Texas.
- 22:53Melisa Finley: And so that type of device isn't maybe applicable to every single ramp.
- 22:59Melisa Finley: And so we do have to balance safety and operations and funding.
- 23:03Melisa Finley: And so I think just the more that we can have people realize, let's make good decisions when we're driving.
- 23:09Melisa Finley: If we're impaired, let's not drive.
- 23:12Melisa Finley: If I'm just inconvenienced, let's go ahead and take that extra time.
- 23:16Melisa Finley: Be aware of your surroundings when you're that right way driver.
- 23:19Bernie Fette: I think you bring up another really important point that we really haven't talked about up to this stage, which is the fact that building and operating a transportation system is a costly endeavor.
- 23:32Bernie Fette: And I remember 30 years ago when I was first starting out at TTI and one of the traffic safety experts at the agency told me, he said, I could pretty much eliminate traffic fatalities as a problem in America almost overnight if you would just give me a blank check.
- 23:54Bernie Fette: And I could basically fix and prevent every sort of, or just about every sort of crash, or maybe not every sort, but possibly prevent quite a few of the different types of crashes from happening.
- 24:07Bernie Fette: You can't put these signs, these signals necessarily at every single spot where someone may think they may do some good.
- 24:15Bernie Fette: You have to really take care to measure how severe the problem is in a given spot, et cetera.
- 24:21Melisa Finley: That's correct.
- 24:22Melisa Finley: We do a lot of data analysis and help transportation agencies with looking at where is the most, you know, appropriate place maybe to use what we call higher cost measures.
- 24:33Bernie Fette: Right.
- 24:33Melisa Finley: Uh, the low cost measures are pretty much everywhere, the signs and markings.
- 24:37Melisa Finley: Um, but yeah, when we're looking at more detection systems, more conspicuity elements, like I mentioned earlier, like the lights, we want to make sure that we're using them in appropriate locations.
- 24:48Melisa Finley: So we try to make that be a data driven approach.
- 24:51Bernie Fette: Okay.
- 24:51Bernie Fette: Last question.
- 24:52Bernie Fette: What is it more than anything else that makes you eager and excited to show up for work every day?
- 25:00Melisa Finley: Something new.
- 25:01Melisa Finley: There's never anything old.
- 25:03Melisa Finley: I do a lot of work with K through 12 students as well, and I always tell them that engineering, especially transportation, there's always something new.
- 25:11Melisa Finley: And that doesn't mean it's not an issue I haven't looked at before, but because of technology and advancements in materials, there's so much that you may be able to answer a problem today that I couldn't answer 10 years ago the same way, right?
- 25:24Melisa Finley: That I did I answered it to the best of my ability 10 years ago with what I had.
- 25:28Melisa Finley: But now with all the technology and the cars, the technology and infrastructure, maybe I can answer it differently and improve upon it.
- 25:36Melisa Finley: And so I think engineering is that way.
- 25:37Melisa Finley: It may be a similar question that you've approached before, but there's so many new ways to answer it.
- 25:43Melisa Finley: It's teamwork.
- 25:44Melisa Finley: I just, I've been at TTI almost 25 years and I just never have had a dull moment.
- 25:51Bernie Fette: Melisa Finley, senior research engineer at the Texas A&M Transportation Institute.
- 25:57Bernie Fette: Melisa, this has been really informative.

- 26:04Melisa Finley: Sure.
- 26:04Melisa Finley: I appreciate it.
- 26:05Melisa Finley: Thank you.
- 26:08Bernie Fette: Wrong way crashes make up fewer than 1 percent of all roadway collisions, but when they happen, those crashes can be devastating, often resulting in serious injury or death.
- 26:21Bernie Fette: That's why the research focus in Texas has concentrated on high speed freeways, where the worst wrong way crashes tend to occur.
- 26:30Bernie Fette: Experts at TTI are developing new countermeasures and refining more established ones to help drivers avoid or escape a rare but perilous roadway hazard.
- 26:44Bernie Fette: Thank you for listening.
