Managing the entire transportation system requires an integrated understanding of all modes. While the focus of transportation system management and operations (TSMO) has been largely focused on vehicles, understanding how the transportation system can work better for bicyclists, pedestrians, and transit can help provide safe, reliable, and cost-effective transportation options to improve communities and economic vitality for people and businesses.

To encourage practical grounding of transportation from the different vulnerable road user perspectives, PSU's Transportation Research and Education Center (TREC) held a two-day training workshop for a cohort of around 100 Washington Department of Transportation (WSDOT) staff members.

The two-day workshop, which featured classroom presentations as well as mobile tours on bike, foot, and public transportation, was held September 26-28 at Portland State University. Presentations on topics like Transportation System Management, Safety, and Innovative Transportation Operations Solutions were given by both professionals of WSDOT—including Statewide TSMO Development Engineer Pam Vasudeva, and Director of Transportation Operations Dongho Chang—as well as guest speakers including Peter Koonce of the Portland Bureau of Transportation and Jingtao Ma of Traffic Technology Services.

Learning objectives included: 

• Identify transportation operation practices and approaches that promote...

As a social determinant of health, transportation significantly contributes to people's well-being. Walkable, bikable, transit-oriented communities are associated with healthier populations. People in such communities are more physically active, less likely to be injured due to a crash, and less exposed to air pollution.

Because of these and other factors, researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are actually being used and what their impact is on policy.

Research conducted by Kelly Rodgers, a National Institute for Transportation and Communities (NITC) Dissertation Fellow, explored how health-related indicators are being used in municipal transportation plans, whether they are institutionalized into transportation agency decision-making processes, and what influence they have on administrative decision-making.

"I have for some time been working at the intersection of health and transportation, and was interested in how health could be better integrated into transportation decision making. And I have also previously done work on performance measures. And so I kind of combined those two things, to see if health-related indicators were a way of getting transportation agencies to consider health in transportation planning," Rodgers said.

How can emerging data sources most effectively be integrated with traditional sources? A new article in the July 2023 issue of Transportation Research Record: Journal of the Transportation Research Board reports that rather than replacing conventional bike data sources and count programs, old “small” data sources will likely be very important for big data sources like Strava and StreetLight to achieve their potential for predicting annual average daily bicycle traffic (AADBT).

The article, "Evaluating the Potential of Crowdsourced Data to Estimate Network-Wide Bicycle Volumes," was authored by TREC researchers Joe Broach, Sirisha Kothuri and Nathan McNeil of Portland State University along with Md Mintu Miah, Kate Hyun and Stephen Mattingly of the University of Texas at Arlington, Krista Nordback of the University of North Carolina, Chapel Hill; and Frank Proulx of Frank Proulx Consulting, LLC.

Transportation agencies have invested heavily in count infrastructure and models to estimate motor vehicle volumes through networks. Efforts to develop network wide bicycle volume estimates have been hampered by lack of bicycle counters and limited other data sources from which to draw volume estimates. Until recently, most data on bicycle activity came from national or regional household travel surveys, along with observed counts of cyclists—...

How do you get from point A to point B? Maybe you bike or take public transit to get to work or school. Perhaps you drive to places that may be farther away, like medical appointments or friends’ houses. Imagine that you didn’t have access to many transportation options—maybe you were unable to drive a car, or the nearest bus stop was several miles away. This is the reality for many folks as they grow older, and their loved ones must then help them get where they need to go.

Older immigrants often live in low-density urban environments, or places where they need to use an automobile of some sort and have limited access to public transportation (like the Dallas-Fort Worth metroplex). This could potentially add stress to both the older folks and the private ride providers who help with transportation. The providers may be at risk for the burden and stress of caregiving, and the older immigrants may lack transportation to important social or health opportunities if the providers they rely on are not available.

Researchers at the University of Texas, Arlington and the University of Connecticut teamed up to fill a gap in the knowledge of the elderly Vietnamese immigrant population in DFW. They sought to learn about the transportation behaviors not only of the Vietnamese adults but also of their ride providers. By increasing knowledge of the transportation...
