The Portland State University Bike Hub has received funding to purchase 25 electric bikes via a new grant from Portland General Electric.

The Bike Hub is a full-service retail bike shop on campus, opened in 2010. The shop offers long-term bike rental through its VikeBike program, a fleet of over 140 bikes offered at low cost (or no cost, based on need). The program’s existing fleet was assembled by collecting and refurbishing abandoned bikes on campus and made available to students for long-term rentals.

PSU will use this funding to purchase 25 Batch Bicycles e-bikes, to supplement the rental fleet and provide greater access to those living further from campus or those with physical barriers to cycling, and serve as a pilot program toward the eventual full replacement of the rental fleet with e-bikes.

Two national research centers at Portland State University have been awarded a new contract from the National Academies of Science (NAS): TCRP J-11/Task 40: Homelessness: A Guide for Public Transportation. We interviewed the two principal investigators to learn more about this new collaboration:

Could you share with us the background and objectives of this new project?

JOHN MACARTHUR, Sustainable Transportation Manager, Transportation Research and Education Center (TREC) at Portland State University

Five years ago the NAS completed TCRP Synthesis 121 report– a synthesis of transit agency practices in interacting with people who are experiencing homelessness. They want to take another look to find out what has changed. Originally, the work was focused on the operational side of things. We’re expanding that scope to look at, not only how are people who are experiencing homelessness impacting the transit system, but also, how can the transit system help that community. 

Transit agencies are looking for best practices– ways to address the issue, both in internal operations but also through partnerships. The project is a combination of a literature review, survey scan, and case study development to elevate some of those lessons learned to a national dialogue.

DR. MARISA ZAPATA, Associate Professor of Land-Use Planning at Portland State University and Director of PSU's Homelessness Research & Action Collaborative (HRAC)

Homelessness is a reflection of dramatic societal failure from multiple systems. And it is both the failure of those systems, but now also the responsibility of those and other systems, to respond and address what homelessness produces. And obviously, the people who are experiencing homelessness are the people who are most impacted by the existence of homelessness. But by continuing to allow homelessness in our society, we also have to recognize that there are additional impacts being felt across other systems - particularly in our public assets around land, transit, public infrastructure. 

What we're really trying to do here is to highlight places that have found innovative ways to engage in supporting people experiencing homelessness. And also to identify solutions such as fare-free transit. 

Why do you think it is so critical to be looking at transit when discussing barriers and opportunities that people experiencing homelessness face?

MARISA

There are a couple of ways in which transit agencies are both impacted by and implicated in homelessness. They also have opportunities to help resolve it. We have seen increases in unsheltered homelessness, particularly on the West Coast. We've got people who are looking for any kind of shelter: living in subway tunnels, sleeping at bus stops, riding rail lines just to stay warm. So you've got people who are experiencing homelessness, which is a critical issue in itself, and it can also be distressing to other passengers.

Looking at the prevention side, how can we ensure that people who are low-wage earners are able to access transportation to jobs and opportunities? If we can keep people at least making minimum wage, then we can often keep people housed by augmenting that minimum wage salary with housing assistance. 

People experiencing homelessness need to be able to access work, health care systems, benefit offices...and the best way to do that is on transit. And so we need to think about how people who are in low-income situations or experiencing homelessness use transit systems to better their lives, but then also understand the impacts of homelessness on our transit systems. 

JOHN

I think transit agencies can no longer look at themselves as just providing transit. Their role in the way a community functions is so much bigger than that. Transit is the connection that gets a lot of people to essential services that will improve their lives. Transit agencies need to rethink how they are serving all riders, including people experiencing homelessness, and how they can - more humanely and with attention - make the system more usable for all riders. Both for the people who are homeless, but also for riders who are interacting with people using the system.

What unique strengths do PSU researchers bring to the table that will deepen our understanding of transit and houselessness?

JOHN

At PSU we have two national research centers that focus on both sides of this coin, and it's exciting that this is the first project for us to work on collaboratively on such an important and timely topic. 

MARISA

Yes, it's the first project of what, we hope, will become a portfolio of work. We've got John, who has an incredible research history with transit agencies and understanding how they function, and is part of TREC, which is one of our national leaders in transportation research. And you've got me. I lead the Homelessness Research and Action Collaborative – one of the few national research centers that is looking specifically at homelessness as an issue. 

There is a history of people who study homelessness avoiding research about unsheltered homelessness. And there's a reason for that. Historically, people will use focusing on sheltered homelessness to avoid talking about the actual solution to homelessness, which is housing and support services to maintain housing. So there is a concern that when you look at other things, you're allowing society to ignore what the real solution is. As a research center, we have been willing to engage in a way that other scholars are hesitant to do so. 

One of the things that meant a lot to me in this study was the inclusion of the prevention side. So it's understanding and accepting responsibility for where you, as a system, might not have been working as the best actor in helping to prevent homelessness, while also asking for assistance to figure out how to be a part of the solution.

What aspect of this project are you most excited about? What do you expect to be most challenging?

MARISA

The two things I am most excited about, one is to build the continued partnership and relationship with TREC. And then secondly, I think, to bring a unique perspective and sensitivity to this work. To avoid this idea of, 'Get rid of the people, or do the minimum so they don't bother the other people.' There is also a security component of transportation. This is an opportunity, particularly at this moment in history, to think about policing in relationship to people of color, many of whom are experiencing homelessness in these communities.

Working on issues in homlessness is some of the most challenging public policy work you can do right now. It is our responsibility to give as much context as possible to understand what the findings really mean. It’s easy for someone to pull a stat from a survey and make a headline in the paper or use it for arguments that were not at all intended. 

JOHN

That attention is both exciting and challenging. But that demonstrates how important the topic is, and how there are widely varying beliefs on how we approach it. This is really that initial step to doing a longer-range research portfolio on this topic area.

This is also an opportunity to not frame this as a situation where you're pitting riders against other riders who are homeless. A big issue for transit agencies is that if some of their riders are complaining and if it’s negatively impacting how often they ride, it hits the agencies’ bottom line. It’s important for those agencies to publicly address safety concerns, while also dismantling negative perceptions of their other riders. That's a tricky path to walk on both sides, but I think that's one of the things we'll be looking at. 

Have you noticed promising approaches in the first six case studies that you hope to revisit?

MARISA

It's really promising to see people bringing in social service organizations to do outreach. That is something we're seeing across a number of public agencies, recognizing that not everyone needs to build out their own social service wing. There are lots of different ways in which people are experiencing homelessness, and reasons why. There is also the stigma around it. If you have a sign up saying "If you are homeless, stop here for help," a lot of people might walk past this. If Instead you're setting up coffee chats, and you've got experienced nonprofits involved and you're asking, are you experiencing stress in your life? That can reach people. 

The other thing that people really don't fully understand about homelessness is that some people experiencing homelessness are really ill and they need intensive health care support. Those tend to be the people who get the most attention, in terms of people reacting and being afraid of them. And so those folks need a very specific kind of outreach. Having people who are there to build the relationships and to really establish trust – which is what one of the cases talked about, that trust development – is so essential to being able to help someone move into housing and be willing to trust service providers again. The agencies that are looking for those partnerships, and are able to effectively implement them, are what I'm most excited to follow up on. 

JOHN

In addition to these promising approaches – like providing crisis support with trained staff and acknowledging how to deal with this in humane and appropriate ways – I think it will be really interesting coming back to these agencies after five years and saying, this is what was written up about you; how have things changed? What worked, what didn't work? The case studies cover different sized cities and geographic areas, so this really is a national approach. Our ultimate goal is to create a guidebook for agencies who are looking to build these types of programs, as well as understand where the network is. What other agencies can they talk to that are already doing that work? So the outcome is a very practical, practitioner-oriented guide.

Since 2013, local transportation activist group Better Block PDX has developed partnerships with organizations across the Portland Metro area. Most notable were the connections that emerged between the communities’ needs for tactical urbanism solutions and the expertise of Portland State University (PSU) transportation students.

Over the last few years, that collaboration evolved and formalized into Better Block PSU, a pathway program that integrates tactical urbanism into the engineering and planning curriculum at PSU. Now led by PSU’s Transportation Research and Education Center, the latest project to advance through the program is Re-imagining a Safer Route to the César Chávez School: N. Willis Blvd. & N. Portsmouth Ave.

A number of teams worked with PSU Urban Planning students in the Fall of 2020, and this project from the César Chávez K-8 School community and the Community Cycling Center was chosen to move onto the second phase with the Spring 2021 PSU Civil Engineering course.

César Chávez PE teacher and project lead Sam Balto shared more about the motivation behind the project, “Not only is this intersection incredibly uninviting for the students and families walking to school, it’s just plain dangerous. A César Chávez student was recently hit by a driver in this intersection. The lighting is poor at night, and drivers on N. Portsmouth are regularly speeding and ignoring pedestrians. This is a key route to our school and something has to change.”

Sam, a self proclaimed "tactical urbanist," is most excited for his students to see firsthand how they can effect change. "Tactical urbanism is incredibly empowering and addictive. Having my students be the ones changing the built environment for themselves will be a learning experience in community action and civic engagement they will never forget."

Two community members give feedback on safety improvements they would like to see at the N. Willis Blvd and N. Portsmouth Ave intersection.

This isn’t Sam’s first time engaging with the parents and students on improving the safety and connectedness of the school’s walking routes. Over the past three years he’s been working closely with Community Cycling Center’s Safe Routes to School Coordinator William Francis who organizes Walk n’ Roll to School Days, bike clubs, and youth bike camps with César Chávez. “The North Portland neighborhood around the school is incredibly walkable, with the exception of a few problematic intersections," shared Francis. "The cumulative impact of these small hurdles creates the perception that walking to school is dangerous.”

The project team submitted their proposal to the Better Block PSU program looking for a tactical urbanism solution in the short-term, as well as to be better equipped with the technical know-how to advocate for larger, permanent changes through the city and solicit grant funding.

“In the summer of 2019 we worked with the City Repair Project and our César Chávez students and their families to paint the school’s parking lot using the students’ designs. Sam and I didn’t touch the paint. The community did it all,” shared Francis. “The parents are coming up with great ideas to improve walkability to the school, and we hope we can keep that momentum and enthusiasm going despite the impacts from COVID-19 closures.”

The school’s interest in transportation did not come to a complete standstill this summer, as Balto worked with volunteers to create an interactive “traffic garden” in an unused corner of the playground at the César Chávez School.

“We're always striving to center and empower our parents and students to support the changes they want to see. We’re their partners,” emphasized Francis. “By joining this Better Block PSU program, we want to facilitate the families’ connection to the university.”

Balto and Francis have gathered a lot of ideas from the students, parents and surrounding community on how this intersection could be improved. Many people liked the idea of a traffic circle, raised crosswalks, or curb bump-outs as potential traffic calming ideas. The community has the solutions, but the next step is removing the barriers to achieving them.

Subcontract: NCHRP 15-73 Design Options to Reduce Turning Motor Vehicle – Bicycle Conflicts at Controlled Intersections

Sponsor: National Cooperative Highway Research Program (NCHRP)

Research Team Lead: Christina Fink, Toole Design Group

Portland State Investigators: Christopher Monsere, Nathan McNeil and Sirisha Kothuri

One of the most common locations for motor vehicle-bicyclist crashes is at controlled intersections. Particularly dangerous is the conflict between through bicyclists and turning drivers (either left or right). Despite widespread acknowledgement of this problem, transportation engineers and planners still lack definitive guidance on how to safely and effectively design for bicyclists at intersections in the United States.

In a newly contracted project, awarded to Toole Design Group by the National Cooperative Highway Research Program (NCHRP), a team of researchers will identify design best practices to reduce conflicts at intersections. In addition to Toole, the team includes researchers from Portland State University, Oregon State University (David Hurwitz), and Safe Streets Research & Consulting (Rebecca Sanders). Christopher Monsere, Nathan McNeil and Sirisha Kothuri are the PSU team members.

Check out a related research project led by Monsere: Contextual Guidance at Intersections for Protected Bicycle Lanes.

Relatedly, this same team of PSU researchers has joined a second contract lead by TTI: NCHRP 15-74 Safety Evaluation of On-Street Bicycle Facility Design Features.

THE ISSUE

Design practices that simply drop bicycle pavement markings and signs at intersections, providing no positioning guidance for motorists or bicyclists, can lead to confusion over who has the right-of-way. Some jurisdictions continue bicycle lane markings all the way through intersections; in others, the lanes are dashed. Moreover, a variety of innovative treatments including bike boxes, the use of color, bicycle signals, and separated crossings are being used in different combinations and applications across the country. The variability of intersection design has resulted in design guidance which does not provide specific thresholds for selecting bikeway treatments. 

This project seeks to remedy that by coming up with specific design guidance for transportation practitioners to use in reducing turning conflicts between motor vehicles and bicycles at controlled intersections.

THE RESEARCH PLAN

After reviewing existing literature to synthesize the current state of the practice, the research team will interview practitioners to gain additional insight into current practices, and the criteria used to select design treatments for bicycle facilities at intersections. The team will then select a set of intersections to analyze more closely in terms of safety and operations. 

The researchers plan to use three methods—crash analysis, conflict analysis, and human factors analysis (using a driving simulator)— in a tiered approach to examine bicycle safety. This will help clarify the relationship between key risk factors and various bicycle facility designs in varying intersection contexts, and ultimately disentangle these relationships in order to provide substantive guidance to practitioners.

The team will use their findings to develop a decision tool and design guidance, and will also create training materials to help practitioners make informed decisions.

TIMELINE

The research is just getting off the ground as of October 2020, and is expected to conclude in October 2023. To stay updated about its progress and learn findings from other PSU transportation research, subscribe to our monthly TREC newsletter.

Effect of Residential Street Speed Limit Reduction from 25 to 20 mi/hr on Driving Speeds in Portland, Oregon

Christopher Monsere, Sirisha Kothuri, and Jason Anderson; Portland State University

In 2015, the City of Portland adopted Vision Zero's objective of eliminating transportation-related fatalities and serious injuries. Speed, through analysis of crash data, was determined to be a contributing factor in 47% of the fatal crashes observed in Portland. Thus, one of the pillars in the Vision Zero Action Plan is reductions in motor vehicle speeds. The Portland City Council approved an ordinance reducing the speed limit on all residential streets to 20 miles per hour (mph) in January 2018.

This research project, funded by the Portland Bureau of Transportation and conducted at Portland State University, looked at 58 locations before and after the speed limit change and found that the change likely reduced driving speeds by small but significant amounts.

While Christopher Monsere of PSU Civil Engineering served as the Principal Investigator on the project, the bulk of the analysis was completed by civil engineering professor Jason Anderson. Overall, the analysis suggests that the reduction of posted speed limits to 20 mph has resulted in lower observed vehicle speeds and fewer vehicles traveling at higher speeds (over 30 mph). It is most noteworthy that the reduction in the percentage of vehicles faster than 30 mph and 35 mph are larger in magnitude than the other changes. These changes are more meaningful for the Vision Zero speed reduction efforts, given the link to crash severity for vulnerable road users.

Subcontract: NCHRP 15-74 Safety Evaluation of On-Street Bicycle Facility Design Features

Sponsor: National Cooperative Highway Research Program (NCHRP)

Research Team Lead: Dr. Bahar Dadashova, Texas A&M Transportation Institute

Investigators: Christopher Monsere, Sirisha Kothuri and Nathan McNeil of Portland State University; and Toole Design Group

In recent years, there have been over 600 bicyclist fatalities annually in the United States. This sobering statistic has motivated a number of recent studies, including the recently released National Transportation Safety Board study, “Bicyclist Safety on US Roadways: Crash Risks and Countermeasures (PDF). ” That report notes that midblock crashes account for a disproportionate number of bicyclist fatalities and severe crashes, and that separated on-street bicycle facilities may reduce the likelihood of these crashes. However, there are only limited data on the safety outcomes of separated on-street bikeways in the U.S., despite their increasing popularity compared to non-separated alternatives.

On-street bicycle facilities provide exclusive travel lanes for bicyclists within the roadway. Non-separated on-street bicycle facilities are horizontally delineated from motor vehicle traffic by pavement markings, such as a painted buffer or striping. Some non-separated facilities are colored either over their entire length or through conflict areas. Separated on-street bicycle facilities are separated from motor vehicle traffic both horizontally and vertically by flexible delineators, curbs, parking lanes, or other barriers.

In a newly contracted project funded by the National Cooperative Highway Research Program (NCHRP), Texas A&M Transportation Institute with support from Portland State University and Toole Design Group will work to provide practitioners at state departments of transportation (DOTs) and other transportation agencies with data-driven guidelines for selecting context-appropriate bikeway design features. This will support the implementation of safety improvements to existing separated and non-separated on-street bicycle facilities, as well as the planning of new facilities. The guidelines will be based on an up-to-date, quantitative analysis of crash patterns as well as an evaluation of the roadway characteristics, land use patterns, and human factors that increase conflicts and the risk and severity of midblock crashes that involve bicyclists.

Seeking to address safety concerns and promote bicycling in their communities, many state and local DOTs have already installed separated bicycle facilities. Many more agencies are exploring the potential of doing the same, but need more detailed information on anticipated safety improvements of specific design features for a range of sites and contexts. The new guidance from this project will deepen our understanding of the relationship between design features and the risk of midblock (non-intersection) bicycle-involved crashes and conflicts. The research team will also identify implementation pathways that will allow practitioners to put the results of this project into practice, and directly disseminate the project results with practitioners and state DOTs.

Relatedly, this same team of PSU researchers has joined a second contract lead by Toole Design Group: NCHRP 15-73 Design Options to Reduce Turning Motor Vehicle – Bicycle Conflicts at Controlled Intersections.

The project began in September 2020, and is expected to conclude in August 2023. To stay updated about its progress and to hear about findings from other PSU transportation research, subscribe to our monthly TREC newsletter.

A national non-motorized count data archive, BikePed Portal provides a centralized standard count database for public agencies, researchers, educators, and other curious members of the public to view and download bicycle and pedestrian count data. It includes automated and manual counts from across the country, and supports screenline and turning movement counts.

BikePed Portal was established in 2015 by Transportation Research and Education Center (TREC) researchers at Portland State University through a pooled fund grant administered by the National Institute for Transportation and Communities (NITC). Other project partners include the Federal Highway Administration, Oregon Department of Transportation, Metro, Lane Council of Governments, Central Lane MPO, Bend MPO, Mid Willamette Valley Council of Governments, Rogue Valley Council of Governments, City of Boulder, City of Austin, Cycle Oregon, and Oregon Community Foundation.

If you’re interested in using BikePed Portal for archiving bicycle and pedestrian counts for your community, please contact us at bikepedportal@pdx.edu.

Hau Hagedorn, associate director of TREC, has been a driving force behind BikePed Portal since its conception. In early 2018 data scientist Tammy Lee joined TREC to manage our transportation data program. A primary focus of her role at TREC is the continued development and implementation of BikePed Portal, and she’s written quite a few case study blogs using BPP. Celebrating the launch of the new dashboard, we interviewed Hau and Tammy to learn more.

Before we jump into discussing BikePed Portal, could you share why access to better quality bike and ped data is so important for the transportation industry?

HAU HAGEDORN (ASSOCIATE DIRECTOR, TREC at PORTLAND STATE)

In general, data is powerful in decision-making. Agencies need to know how many people are biking and walking. How many trips happen per year? Per facility? What does that look like over time? Site by site, trail by trail, system by system. Accurate, centralized data (or, lack of it) can make or break the case for building or enhancing bike and walk facilities. Right now, the lack of significant data is a barrier. One thing that we hear a lot in pedestrian studies is ‘people don't actually walk there, we never see them.’ When you actually do the work and go out and count, intersections or segments or facilities, it becomes apparent that people are using it beyond expectations. In active transportation, we are always trying to play catch-up to the levels of vehicle data that is collected and analyzed. Beyond application for case studies, data like this is critical to advancing active transportation research scope and impact. The NCHRP released some great guidance, the Guidebook on Pedestrian and Bicycle Volume Data Collection that also details some use cases across the U.S.

USE CASES FOR BICYCLE AND PEDESTRIAN COUNT DATA IN A NATIONAL ARCHIVE 

Understand how existing infrastructure is used: How many trips per year happen on a facility?  Show changes over time, site by site, trail by trail, system by system.

Demonstrate impacts with before/after studies: Communicate how funds have been used, and evaluate the effects of new infrastructure on pedestrian and/or bicycle activity.

Tell the story: Share count data in infographics, articles, grant reporting, and annual reports while answering how people are using the system and how it’s grown.

Guide prioritization: There is potential to use data for system planning, as well as prioritize where needs are, particularly for bike-ped projects.

Make the case: Use data to support grant applications and validate identified needs.

Change design: Using volume, a shared use path LOS calculator could be used to determine how wide a facility should be designed or improved.

Improve data quality: Providing count device maintainer information about the quality of the data – both filtering “bad” data and letting the maintainer know when a device may be broken.

Increase access and ease of data: Support data requests automatically so staff don’t have to individually respond to data requests.

Your team developed BikePed Portal – a central data repository for national bike and ped data. Why is this significant?

TAMMY LEE, Ph.D. (TRANSPORTATION DATA PROGRAM ADMINISTRATOR, TREC at PORTLAND STATE)

Most often agencies have a lot of count files of all different types, and they're all siloed on different computers, different machines. There isn’t consistency in how those data files are maintained, stored, or created. It can be overwhelming. So using a central data repository is an opportunity for agencies to standardize their data and store it in one shared location. That way, it's just not sitting on someone's computer but instead accessible by multiple people within an organization.

What is unique about BikePed Portal compared to what else is out there? Is there a feature you are most excited about?

HAU

U.S. cities and jurisdictions collect data for their specific entity, which means you have to go to various sites to compare the volumes of walking and biking across a state or the country. In the BikePed Portal dashboard that comparison is easier, especially with the performance measures we have set up. For example, within the Portland region, we have Metro collecting count data, we have the City of Portland collecting counts, the Tualatin Hills Park & Recreation District, City of Beaverton, as well as the state of Oregon. Once we get all of that data into BikePed Portal, and these agencies authorize the view of that data, you have all of those disparate data sources in one place. It provides a more comprehensive view of what the actual volumes are across an entire network and system. I’m most excited about the potential for stronger coordination between these entities as they collaborate on infrastructure projects and other types of active transportation programs and planning.

Who are the intended users of BikePed Portal?

TAMMY 

U.S. transportation agencies, planners, and advocates who need bike/ped counts, as well as those in academia like students, researchers, and educators. Right now you can download the hourly data we have by site. There are a few sites that have years and years worth of data, which is pretty impressive for a long-term dataset. If you're a researcher, and you're trying to figure out which city or which jurisdiction has the most data, you can just poke around BikePed Portal. It saves that researcher the time and frustration of having to reach out to different cities asking, does this data exist? Can I access this data? And, once they receive the data, it's all standardized and easy to use. Versus if they had reached out to those agencies, they’re going to get some text files, csv files, handwritten pdfs, machine unreadable Excel files.

Last year we released research on bike and ped count data QA/QC from Portland State researcher Nathan McNeil. How important was this QA/QC process to the design and function of BikePed Portal?

TAMMY

We make it a point to ingest different types of data sources and put them together all in one location. You can have counts from EcoCounter, from different makers like Traffix, and manual counts, and it all gets inputted into BikePed Portal. And so because of that, and because we have a nice database in which to do it, we're able to use this really large and diverse sample size to do an analysis developing QA/QC metrics. Count data can have some really large peaks. For example in Portland, there's the World Naked Bike Ride Day - it’s huge. That day would automatically get flagged for the data owner because the volume is so high. But the data owner is given the choice to validate or invalidate it. They know their data better than any outsider. That validation process helps researchers and others who download the data; they can check, was this data QA/QC'd by the owner? If it wasn't, then they can have that chance to sort of validate it themselves and figure out if they want to use it or not.

What's next? Is there another evolution or feature in the works?

HAU

Our next goal is really broadening the user base and expanding the datasets available in BikePed Portal. Also, we’re really focused on integrating AADNMT calculations (Annual Average Daily Non-Motorized Traffic). For cities that meet a certain volume of counts, we will be providing that metric. Just like with traffic data, this gives you a sense of the volume of usage for your analysis area. If anyone is interested in learning more about BikePed Portal and how they can use it for archiving bike and pedestrian counts for your community, they can reach out to us at bikepedportal@pdx.edu.

A new paper in the Journal of Planning Literature by Michael McQueen, Gabriella Abou-Zeid, John MacArthur and Kelly Clifton of PSU took a look at micromobility. The article focuses on the role of new modes like shared e-scooters in the efforts to cultivate a more sustainable transportation system by reducing greenhouse gas emissions, providing a reliable and equitable transportation service, and enhancing the human experience. Their review of the literature shows that the sustainability impacts of these modes are at present mixed, and are likely to remain so without more targeted interventions by local stakeholders. Yet, the operations and use of micromobility systems are quickly evolving and hold promise for contributing to a more sustainable transportation system.
