Latest / Thinking Transportation: Engaging Conversations about Transportation Innovations / Policy, Priorities, and Possibilities. What might we see from new leadership at USDOT?
Transcript
- 0:14Bernie Fette (host): Hello again.
- 0:16Bernie Fette (host): This is Thinking Transportation, a podcast about how we get ourselves and our stuff from one place to another, and all the implications of what happens in between those places.
- 0:28Bernie Fette (host): I'm your host, Bernie Fette, editor-at-large at the Texas A&M Transportation Institute.
- 0:33Bernie Fette (host): And today, I'm delighted to be visiting with my boss.
- 0:38Bernie Fette (host): Greg Winfree is the agency director here at TTI.
- 0:41Bernie Fette (host): He's also a former U.S.
- 0:42Bernie Fette (host): assistant secretary of transportation.
- 0:45Bernie Fette (host): Having worked in those very different, but closely related fields-- the world of public policy and transportation and then in research-- he probably has some unique observations to share, especially with the changing of the guard that we're still adjusting to.
- 0:59Bernie Fette (host): Greg, we know you're a pretty busy guy without a lot of spare time.
- 1:03Bernie Fette (host): So thanks for sharing some of that with us today.
- 1:05Greg Winfree (guest): Well, thanks so much, Bernie.
- 1:07Greg Winfree (guest): It's a great pleasure to be here with you.
- 1:09Bernie Fette: By the way, happy birthday.
- 1:10Greg Winfree: I appreciate that as well.
- 1:13Greg Winfree: The years keep flying by.
- 1:14Bernie Fette: One more trip around the sun, and if it was on social media, it must be true.
- 1:19Bernie Fette: Right?
- 1:19Greg Winfree: Well, you know, that's where all of the best information comes from.
- 1:24Bernie Fette: Okay.
- 1:26Bernie Fette: So it's been about four years now, since you finished your last gig before your current one, when you were at USDOT, assistant secretary of transportation.
- 1:37Bernie Fette: What do you think has changed the most in terms of transportation policy and practice?
- 1:44Greg Winfree: You know, many things have changed; many haven't.
- 1:49Greg Winfree: One thing I think that kind of lost steam or at least lost direction was a focus on investment in infrastructure.
- 1:59Greg Winfree: You remember in the previous administration put out their infrastructure plan, it had a lot of non-infrastructure elements to it.
- 2:09Greg Winfree: So it wasn't a truly dedicated infrastructure plan.
- 2:12Greg Winfree: And that caused a lot of consternation in Washington about how to get that right.
- 2:16Greg Winfree: And I think the roads and bridges aspect kind of got put on the side burner, although they remained important.
- 2:25Greg Winfree: So, uh, there's still an undercurrent of an effort to resuscitate that in Washington, I remain hopeful that we'll see some legislation coming out of Washington that puts significant investment into transportation infrastructure.
- 2:39Greg Winfree: 'Cause I think that really is an area that is in need of attention.
- 2:44Greg Winfree: What, with the declining revenues being generated by the highway trust fund from the gas tax, et cetera.
- 2:50Greg Winfree: Another area that has changed dramatically at the department of transportation has to do with connected vehicle technologies.
- 2:59Greg Winfree: When I was in Washington, connected vehicles were the technologies that allowed vehicles to talk to one another so that you had better situational awareness in order to avoid crashes and conflict between vehicles, as well as getting a convenience and road weather advanced warnings or advanced notice.
- 3:20Greg Winfree: But the radio frequency allocation from the FCC that was allotted to allow for connected vehicle technologies has been under threat largely since 2014, when Google came out with the self-driving car and had statements that they wouldn't need to rely upon connected vehicle technologies; that their rolling computer would have all of the answers in every driving scenario.
- 3:47Greg Winfree: As the years went on, self-driving technology developers realized that having the ability to be connected with others in the flow of transportation where in traffic would be of benefit.
- 3:59Greg Winfree: It was a sensor that they could add that would improve the operational capabilities of their vehicles.
- 4:05Greg Winfree: So that argument went away.
- 4:07Greg Winfree: But the threats against the spectrum that had been allocated continued as the Wi-Fi industry were seeking more real estate on the radio frequency spectrum, so that they could have a contiguous pathway for the throughput of data that wireless devices utilize and capitalize upon.
- 4:31Greg Winfree: So literally, they wanted you to get your Hulu faster.
- 4:34Greg Winfree: They wanted you to get your Netflix faster.
- 4:37Greg Winfree: When I was at DOT, we used to say, we don't want people being entertained to death, but that's where we are.
- 4:43Greg Winfree: It remains a contentious issue in Washington and it looks as if you're figuring out which horse is winning the race thus far, I would say it's certainly leaning toward Wi- Fi getting their wishes and getting 45 of the 75 megahertz that had been allocated to transportation safety.
- 5:04Bernie Fette: Okay.
- 5:04Bernie Fette: On the other side of that coin, does anything come to mind in terms of what seems to have not changed at all since you were there?
- 5:12Greg Winfree: So things that haven't changed--I would certainly say the mission of the department remains strong.
- 5:20Greg Winfree: A way to think about particularly DOT is there is a strong cadre of career employees, and those are the folks who by definition spend their careers at agencies like DOT, but they're also the custodians of the corporate history and knowledge and the ability to pass that information from generation to generation.
- 5:46Greg Winfree: And then you have the political appointees who come in almost episodically, they're attached to an administration.
- 5:53Greg Winfree: So they're going to be there at a max eight years.
- 5:57Greg Winfree: So they're the ones who need to rely upon the expertise that the career staff has built.
- 6:04Greg Winfree: So the mission that's carried forward by the career folks that at USDOT remains the same.
- 6:13Greg Winfree: They remain committed to what they do to ensure the safest and most efficient transportation systems for the American traveling public.
- 6:23Greg Winfree: So certainly that mission and that dedication for the organizational mission hasn't changed.
- 6:29Bernie Fette: What hasn't changed, it sounds like, is the stability of the organization in general.
- 6:34Greg Winfree: I would say that that's a definite yes.
- 6:37Greg Winfree: You do get some when the political appointees come on board, they of course are aligned with the priorities of the administration.
- 6:45Greg Winfree: So there'll be some tweaking around the edges, but it's fair to say that the mission of Federal Highways is well-defined, the mission of FAA, the mission of the Maritime Administration, Federal Motor Carrier Safety Administration, NHTSA-- those mission areas have been well-defined and are the province of those operating administrations.
- 7:09Bernie Fette: So it sounds like we can at least count on some measure of continuity.
- 7:12Greg Winfree: Absolutely.
- 7:12Bernie Fette: Fair to say?
- 7:14Greg Winfree: For sure.
- 7:15Bernie Fette: When I was getting ready for our conversation today, Greg, I did just a little bit of online searching and noticed that first time that we had the appointment of a secretary of transportation was in 1967.
- 7:28Bernie Fette: And since then, the department's been led by a fairly diverse collection of people--both men and women, African-American, Asian, Hispanic, Japanese heritage, and now the first LGBT American.
- 7:43Bernie Fette: And I'm just wondering, does that distinction tell us anything?
- 7:46Bernie Fette: Is diversity somehow more relevant in the context of transportation?
- 7:51Greg Winfree: You know, that's a keen observation and a great question.
- 7:57Greg Winfree: You know, you've probably heard me say out on the speaking circuit, that transportation is the circulatory system of, really, our economy and our American way of life.
- 8:08Greg Winfree: And it, you know, much like the circulatory system in the human body, if you get an occlusion on any particular artery, you have a problem, right?
- 8:19Greg Winfree: So these are issues that hit the American public at all levels, regardless of if you're a personal vehicle owner or if you're a transit rider, these issues matter.
- 8:33Greg Winfree: And these are literally where the rubber hits the road.
- 8:36Greg Winfree: Now, when I worked at DOT, Deputy Secretary John Porcari, he used to always say, there are no Republican or Democratic potholes.
- 8:45Greg Winfree: People call their legislator's office; they want solutions.
- 8:51Greg Winfree: They want them now.
- 8:52Greg Winfree: And those are the kinds of low-hanging fruit that politicians should be able or expected to deliver on.
- 8:59Greg Winfree: Right?
- 8:59Greg Winfree: So these are fundamental matters for the movement of people, data and goods in the U.S.
- 9:07Greg Winfree: And there's no particular group that owns it any greater than any other.
- 9:12Greg Winfree: So since that's the case, and since the need to connect with constituents and constituencies around the country, on these issues, you need to be reflective of who you're representing in this moment, most fundamental of agencies.
- 9:28Greg Winfree: So I think that's why you see such a widespread talent that has led the department.
- 9:34Greg Winfree: To a person, they're all recognized as motivational leaders.
- 9:38Greg Winfree: They may not be transportation experts.
- 9:40Greg Winfree: They will be by the time they leave.
- 9:42Greg Winfree: But more importantly, they're able to coalition-build, not just internally at DOT, but across government with organizations like TRB and ITS America and ITE.
- 9:55Greg Winfree: So it really is almost a pastoral kind of leadership approach to the department and its mission and its ability to bring parties together for a common goal and common good.
- 10:07Bernie Fette: And I know we're talking about things at the federal level, but it sounds like what you're saying can easily be applied to state, local in the context of transportation, too, right?
- 10:18Greg Winfree: It can, but state and local tends to get a bit more targeted or there may be issues that are important to the state that have not migrated to the federal level, or maybe even anathema to the federal level.
- 10:34Greg Winfree: You know, some of the pushback on bike and ped access and complete streets thinking, you hear some criticisms.
- 10:44Greg Winfree: I even testified before the[Texas] Senate yesterday and received a question about whether or not there has been any analysis into the cost-benefit ratio of Toward Zero Deaths.
- 10:57Greg Winfree: There was a recognition that it started as a federal initiative that migrated down to the states.
- 11:02Greg Winfree: And there was a question that while we certainly don't want anyone to die on our roadways, at what economic expense is this being undertaken?
- 11:12Greg Winfree: So again, it depends on the state.
- 11:13Greg Winfree: Depends on the legislatures.
- 11:15Greg Winfree: It depends on what their constituents are feeding back.
- 11:18Greg Winfree: So...
- 11:19Greg Winfree: so the perspectives of the individual states will reflect their individual realities.
- 11:26Bernie Fette: What about diversity in terms of transportation?
- 11:29Bernie Fette: Wondering about your thoughts on what that topic has come to mean, what it's come to encompass since the days when transportation was basically highway only, and maybe how you see that evolution unfolding more in the years ahead.
- 11:45Greg Winfree: Well, it's probably a two-part answer to that question.
- 11:50Greg Winfree: The first part would be, there is more of a focus in transportation decision-making impacting disadvantaged or minority communities.
- 12:01Greg Winfree: There's a great book called The Big Roads that talks about how highway interstate placement decisions were made back in the Fifties when you literally had interstates going through the middle of Black and Brown neighborhoods, and bisecting them with no way to get from one side to the other; these are communities that have been historic.
- 12:22Greg Winfree: So it caused community collapse.
- 12:24Greg Winfree: So you're hearing more about equity in transportation now, and it's important that that conversation is going on, and not just from the infrastructure-building perspective, but as we look at the rollout of advanced technologies to improve mobility, because really that's what the term is nowadays.
- 12:43Greg Winfree: Transportation is a bit of an anachronism that focuses on the 10 operating administrations, but it is a seamless as possible, cohesive system of systems, and they all interconnect and interrelate.
- 12:58Greg Winfree: So that's why it's now one that focuses on mobility.
- 13:01Greg Winfree: But looking at mobility, particularly with respect to electrification and personal mobility vehicles being more available and the shared economy, the equity questions become well, why is Uber circulating in the more affluent neighborhood and difficult to get service in disadvantaged communities?
- 13:24Greg Winfree: You know, who's making the decisions on where bike share goes or scooter share?
- 13:29Greg Winfree: You know, who's paying attention to the unique issues in urban environments with respect to accommodating pedestrians and bikes.
- 13:38Greg Winfree: And how does that work in disadvantaged communities and those sorts of things.
- 13:42Greg Winfree: How do...
- 13:42Greg Winfree: how do you improve transit service for those that don't have the ability or the means or the wherewithal to have their own vehicles to get back and forth and to and fro to work and grocery, et cetera.
- 13:54Greg Winfree: So from a diversity perspective on how transportation impacts communities, that's a conversation that has grown significantly over time with respect to the diversity of the mix of operating administration thought...
- 14:10Greg Winfree: that's a great question because there was a challenge, certainly when I was at DOT of where does bike/ped fall?
- 14:17Greg Winfree: Is that a NHTSA responsibility?
- 14:19Greg Winfree: Is that a Federal Highways responsibility?
- 14:22Greg Winfree: Do we need to create a new office that focuses on personal mobility in light mobility for short-distance travel?
- 14:31Greg Winfree: So we looked at, you know, since it was the highway, only years, a lot has moved around.
- 14:36Greg Winfree: Although the docket at DOT hasn't changed, the issues with Federal Motor Carrier and NHTSA haven't changed; organizations have been created to specially focus on those that were born out of Federal Highway's mission as it became more specialized.
- 14:51Greg Winfree: So I think we'll continue to see that.
- 14:53Greg Winfree: Where you're going to need to figure out...
- 14:55Greg Winfree: where does low-altitude transportation fit?
- 14:57Greg Winfree: Is it within the FAA mission, or is there a need for a separate focus?
- 15:04Bernie Fette: And when you say low-elevation, you're talking about unmanned vehicles, drones?
- 15:10Greg Winfree: Yes, drones.
- 15:11Greg Winfree: Delivery drones.
- 15:12Greg Winfree: And even the people-mover drones that companies like Uber Elevate and others are exploring from an FAA perspective.
- 15:21Greg Winfree: You know, they control access to the national airspace of course, in partnership with the military, but national airspace starts at about 500 feet.
- 15:32Greg Winfree: So from 499 down, who's really responsible for that?
- 15:37Greg Winfree: There's going to be a need for a complex traffic management system.
- 15:41Greg Winfree: You know, what's that gonna look like to have four- dimensional traffic management?
- 15:45Greg Winfree: So those are challenges that are near-term as we start to look at Amazon and others chomping at the bit to get drone deliveries, right?
- 15:55Greg Winfree: Others looking at how do I move people from point A to point B in that same airspace, along with general aviation that already operates there along with medevac helicopters, news helicopters, you know...
- 16:07Greg Winfree: there's a lot of activity already in the 499 feet and down space, and it needs to be deconflicted before you turn on the switch and allow access to, you know, what otherwise looks like just open sky.
- 16:22Bernie Fette: We've come a pretty long way since the highway-only days, right?
- 16:25Greg Winfree: We have.
- 16:26Bernie Fette: You mentioned a little while ago, how there's no such thing as a partisan pothole.
- 16:33Greg Winfree: Mm-hmm.
- 16:33Bernie Fette: Of course, depending on who you talk to, some people believe--a lot of people believe--that our nation has become very divided.
- 16:40Greg Winfree: Mm-hmm.
- 16:42Bernie Fette: So, I'm wondering to what extent, if any, can transportation be one of those rare areas of public policy that might offer a path to common purpose and shared aspirations?
- 16:56Greg Winfree: You know, that's an interesting way to look at it, and I would like to say that the answer is, yes, it would be kind of a load stone where those ideas could carry forward.
- 17:08Greg Winfree: But I think the truth of the matter is, Issues in and around transportation that have common goal, common purpose are going to be limited to that realm.
- 17:17Greg Winfree: And issues that fall in other areas or with under other agencies that have historically or recently been contentious will remain so.
- 17:28Greg Winfree: So it's a bit disappointing to have to admit that, but I really think that's where this will fall out.
- 17:36Greg Winfree: And there's not always unanimity in the execution of the transportation mission.
- 17:41Greg Winfree: You know, there's still a lot of not-in-my-backyard.
- 17:44Greg Winfree: There's still a lot of, what are the environmental impacts for decisions that are made?
- 17:52Greg Winfree: Don't get me wrong; there is still controversy in how the transportation mission is executed, but more often than not, there's commonality because the constituents and their legislators understand that getting from point A to point B is extraordinarily important.
- 18:09Greg Winfree: And in order to accommodate that, you know, we need to shake hands across the aisle and move the agenda forward.
- 18:16Bernie Fette: The American Society of Civil Engineers report card on America's infrastructure came out recently.
- 18:22Bernie Fette: Now and then, we have a big wake-up call when it comes to transportation infrastructure like we had when the I-35 bridge collapsed in Minnesota 13 years ago.
- 18:34Bernie Fette: When you look at our current conditions and the trends related to America's transportation infrastructure, is there anything that keeps you up at night?
- 18:43Greg Winfree: You know, state of good repair writ large remains problematic.
- 18:48Greg Winfree: So the grade won't fluctuate much.
- 18:50Greg Winfree: Y'all will remember this from when you were in formative school.
- 18:55Greg Winfree: One teacher's B may be another teacher's D.
- 18:58Greg Winfree: So, so we're failing our nation.
- 19:02Greg Winfree: We're failing to keep up the basic infrastructure that was put in in the fifties that's already over-taxed to keep it in a state of good repair.
- 19:12Greg Winfree: So in I-35 is a catastrophic event.
- 19:18Greg Winfree: It's what happens when the dollars and cents aren't allocated for routine maintenance.
- 19:25Greg Winfree: You know, you don't get to the catastrophic problems unless routine maintenance has been overlooked.
- 19:31Greg Winfree: So the problems that we're seeing only get worse over time, and now we're four more years in without a significant infusion of cash to focus on it, or a significant technological improvement.
- 19:43Greg Winfree: So it's...
- 19:44Greg Winfree: it's a big problem.
- 19:45Bernie Fette: And it's a big problem in a suite of big problems.
- 19:50Greg Winfree: Right.
- 19:50Bernie Fette: Especially considering being a little over a year into a pandemic, for instance.
- 19:56Greg Winfree: That's right.
- 19:57Greg Winfree: But if anything keeps me up at night, it's the fact that the system, top to bottom, has not received the attention that it needs--not deserves--that it needs over time.
- 20:08Greg Winfree: And those underlying issues are only getting worse.
- 20:12Bernie Fette: My last question for you though, I have to preface by telling listeners that Greg is somebody who appreciates motorcycle riding, and he also appreciates his Chihuahua.
- 20:25Greg Winfree: For sure.
- 20:25Bernie Fette: Yeah.
- 20:26Bernie Fette: Who is named Maya.
- 20:28Bernie Fette: Shortly after Greg came to work at TTI, I saw a delightful photo of him on his motorcycle with a sling over his shoulders that has a pouch just big enough for Maya to fit into.
- 20:40Bernie Fette: That photo of you, Greg-- your hog and your dog...
- 20:43Greg Winfree: Yeah, that's right.
- 20:46Bernie Fette: Yeah, made me think of how transportation it's always had an element to it that was more than just the practical task of showing up someplace on time out of obligation or need.
- 20:58Bernie Fette: And that's something that a lot of us have felt, especially during a pandemic when...
- 21:02Bernie Fette: when we just felt the need to get out and about for nothing more than that, just getting out and about.
- 21:09Bernie Fette: I wonder if that's something you've thought about and how we need to prepare for and incorporate that element in how we think about transportation.
- 21:17Greg Winfree: Well, there's a certain tension there.
- 21:21Greg Winfree: We're blessed to live in a country where we've got significant automotive choices that you can align and match to your personality as well as the basic transportation needs.
- 21:35Greg Winfree: That's not necessarily the case in other countries around the world.
- 21:39Greg Winfree: In the Eighties, when I was in college, I lived in Budapest, Hungary, and there was an awful Soviet car called the Trabant.
- 21:48Greg Winfree: It was a two-stroke, blue-smoke-blowing...
- 21:51Greg Winfree: It looked like an Animal Cracker box with wheels.
- 21:54Bernie Fette: Wow.
- 21:54Greg Winfree: And you couldn't tell model years other than vehicle color, you probably couldn't find your car in a lineup.
- 22:02Greg Winfree: So it was at least from the spoiled American perspective, a drab and uninviting means of transportation.
- 22:10Greg Winfree: But again, it met the basic need for many of the citizens of that country.
- 22:16Greg Winfree: So we're also blessed with open roads, traffic congestion not withstanding.
- 22:22Greg Winfree: And then we've got the here in Texas cultural driver of one man, one truck.
- 22:29Greg Winfree: So we have a lot of folks who have grown accustomed to having their vehicle with their music.
- 22:34Greg Winfree: So it becomes an extension of comfort expectations.
- 22:39Greg Winfree: And that's why you never really saw a significant uptake.
- 22:43Greg Winfree: You heard a lot of talk about carpooling, but other than examples, that are somewhat scattered thinking of Washington, D.C., with the slug lines where people will carpool in order to avoid sitting in a substantial traffic around the beltway.
- 22:58Greg Winfree: But those kinds of shared experiences are rare.
- 23:02Greg Winfree: And I would even point out that Uber and Lyft started as a means of democratizing transportation, where, Bernie, you would say,"Hey, I'm heading to the Trader Joe's.
- 23:11Greg Winfree: I live here.
- 23:12Greg Winfree: This is the path we have taken.
- 23:13Greg Winfree: Anybody want to catch a ride and chip in for the gas?" And presumably two or three other folks would say, yeah, I'll join you.
- 23:20Greg Winfree: But it turned into single-occupant with a driver, but it didn't do much to improve traffic congestion or really encourage true sharing in this so-called shared economy.
- 23:34Greg Winfree: So all of those cultural factors and comfort factors conspired to keep a lot of cars on the road.
- 23:41Greg Winfree: Even if we're talking about an automated-vehicle future 20 years from now, when you can go to your dealer and buy a self-driving car, we need to start thinking about what incentives can be built in so that people will indeed"share the ride" and cut down on roadway congestion, and all of the attendant factors that idling vehicles create from a climate change perspective.
- 24:04Greg Winfree: So that's why I'm saying there's a lot of impact, and we're at a tension point where giving up what we've grown accustomed to and find culturally desirable can match what the future will dictate from a congestion management, climate change, state of good repair and a bunch of other factors that transportation is considering now, but has not yet come up with policy solutions.
- 24:33Bernie Fette: And I remember from another conversation that we had some months ago talking about the eventual proliferation of self-driving cars--connected cars--and the point that you were making was even whenever those vehicles come to dominate the highway landscape for us, you're still going to have a lot of people who want to drive their'57 Chevys.
- 24:52Greg Winfree: Yeah.
- 24:53Greg Winfree: And you know, you may recall, I used to call it the mosh pit, when you've got'57 Chevys and cars from the Eighties and Nineties.
- 25:01Greg Winfree: And so you'll have analog cars merging and interacting with digital cars in, we need to figure out a communications platform that can de-conflict that or other policies that can de-conflict it.
- 25:16Greg Winfree: So that's why you hear things about dedicated lanes for automated vehicles and other travel pathways, where they can traverse without the inattentive human causing an issue.
- 25:29Bernie Fette: Kind of brings us back to the concept of diversity.
- 25:30Greg Winfree: It does.
- 25:32Bernie Fette: A whole additional level of diversity, just in terms of the mix on the roads.
- 25:36Greg Winfree: That's for sure.
- 25:36Bernie Fette: Greg Winfree--agency director at the Texas A&M Transportation Institute.
- 25:44Bernie Fette: Thank you, sir.
- 25:44Bernie Fette: This has been fun.
- 25:46Greg Winfree: Well, it's been a great pleasure and I appreciate the opportunity to sit and visit and have a nice fireside chat.
- 25:51Bernie Fette: Thank you, sir.
- 25:52Greg Winfree: Take care, now.
- 25:55Bernie Fette: In the policy and practice of transportation in America, some things have changed since the USDOT was established half a century ago.
- 26:03Bernie Fette: Others have remained constant, as Greg Winfree just helped us understand.
- 26:06Bernie Fette: Our need for safe and reliable transportation is simple, and it's immutable.
- 26:13Bernie Fette: But the ways in which we go about providing it are not.
- 26:17Bernie Fette: Whether we're talking modal, cultural, environmental, technological, or some other context, moving people and goods--and all the data that goes with them--is increasingly complex and constantly evolving.
- 26:33Bernie Fette: More than ever, transportation truly touches every aspect of our lives.
- 26:39Bernie Fette: Thank you for listening to Thinking Transportation.
- 26:42Bernie Fette: We hope you'll subscribe and share, and we hope you'll check in with us again next time, when we talk with Edith Arambula-Mercado and Charles Gurganus--both civil engineers at TTI and experts in transportation infrastructure--the same infrastructure that recently got some rather unflattering grades from the American Society of Civil Engineers.
