Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new system to improve data collection at intersections.

The LiDAR system can especially improve multimodal travel at intersections with permissive left turns, which are indicated by a flashing yellow arrow. Previous research has shown that where a flashing yellow arrow, or FYA, is present, cars searching for a gap in traffic may not look for pedestrians. To remove the risk to people walking, some signals are programmed to turn off the FYA when a walk button is pushed. But...

The National Institute for Transportation and Communities (NITC) is proud to introduce a new Dissertation Fellow, Farzin Maniei of the University of Texas at Arlington, and his doctoral research project: Unsupervised Approach to Investigate Urban Traffic Crashes Based on Crash Unit, Crash Severity, and Manner of Collision.

"Knowing that there has not been a day without a fatality on Texas roadway since November 7th, 2000, I have been encouraged to focus my dissertation on traffic safety analysis and traffic crash prediction models to mitigate the socioeconomic burden of traffic crashes. Typically, traffic crashes have been investigated using one or two of three major traffic crash characteristics: number of vehicles involved in the crash (crash units), manner of collision (crash type), and crash severity. Leaving out any of these characteristics may negatively affect our understanding of traffic crash patterns. My dissertation aims to investigate the pattern of traffic crashes across highways and freeways by including all three major traffic characteristics simultaneously. The study attempts to capture various groups of traffic crashes, identify their corresponding hotspots, and understand their associated contributing factors. The study will propose an advanced data-driven tool for decision-making using artificial intelligence. Also, the method provides an automated, scalable process to...

Survivors of intimate partner violence (IPV) experience transportation disadvantages, sometimes due to financial constraints caused by their abusive partners, which can keep them from accessing essential resources. Sarah Leat of the University of Memphis School of Social Work has published an article in the December 2022 Journal of Transport & Health examining how shared mobility services could help fill this transportation gap. Leat, who earned her PhD from the University of Texas at Arlington (UTA), began researching transportation challenges among IPV survivors when she was a National Institute for Transportation & Communities (NITC) Dissertation Fellow at UTA.

The Transport & Health article, "Exploring the feasibility of shared mobility services for reducing transportation disadvantage among survivors of intimate partner violence," is related to Leat's doctoral research project, "Identifying and Measuring Transportation Challenges for Survivors in Intimate Partner Violence Shelters."

Highlights from the article include:

  • Sheltered survivors of intimate partner violence often lack the financial means to afford personal modes of transportation.
  • Shared mobility services may be viable solutions for survivors of intimate partner violence who reside in shelters.
  • ...

Transportation can have a significant impact on vulnerable ecologies, especially in rapidly urbanizing regions such as Dallas/Fort Worth. In order for future professionals to balance the needs of sensitive environments with the mobility of people and goods, they must have the proper tools – among other things, a good grounding in regional mapping technologies.

To introduce high school students to geographic information systems (GIS) and spatial reasoning skills, researchers at the University of Texas at Arlington (UTA) developed a four-week training workshop in ArcGIS and other emerging regional mapping technologies. The workshop was incorporated into an existing high school course focused on the transportation network and environmental justice issues in the communities along the Trinity River. 

Led by the research team from UTA's College of Architecture, Planning and Public Affairs (Joowon Im, Assistant Professor of Landscape Architecture, Alan Klein, Director at Institute of Urban Studies, Amruta Sakalker, Graduate Assistant in Planning), they partnered with CityLab High School in the Dallas Independent School District to pilot this workshop. The curriculum, which can be replicated for use by other teachers, introduces students...

In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where. 

Traditional bicycle counters can provide data for limited sections of the bike network; often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only represents those travelers who are using smartphones or GPS. Combining the traditional location-based data sources with this new, crowdsourced data could offer better accuracy than any could provide alone. 

"Knowing how many people are bicycling on a street is really important for a number of reasons. As just a few examples, bicycle volumes give you a way to understand safety data and determine crash rates. They provide insight into where and how bicycle trips are taking place, which can help plan for new or improved facilities," said Nathan McNeil of Portland State University.

Supported by a pooled fund grant administered by the National Institute for Transportation and Communities (NITC), Dr. Sirisha Kothuri of Portland State University led a research project aimed at fusing traditional and...

NITC researchers Anne Nordberg, Jaya Davis, Stephen Mattingly, Sarah Leat and Mansi Patel of the University of Texas at Arlington have published two new journal articles related to their NITC project, Optimizing Housing and Service Locations to Provide Mobility to Meet the Mandated Obligations for Former Offenders to Improve Community Health and Safety. Read about the original study here, which focused on helping former offenders overcome transportation challenges to reintegrate into society.

The two articles, published in Mobilities and the International Journal of Offender Therapy and Comparative Criminology, disseminate the NITC study among different audiences and disciplines; highlighting the need to address transportation and complex social issues through more than one lens.

In the November 2021 issue of Mobilities, "Towards a Reentry Mobilities Assemblage: An Exploration of Transportation and Obligation Among Returning Citizens," the authors investigated the mobility needs of returning citizens from the perspective of service providers and employers in Dallas, Texas. They interviewed 17 participants who directly served returning citizens in their professional...

Dr. Jandel Crutchfield and NITC scholar Erin Findley of the University of Texas at Arlington have published an article in the January 2022 issue of Child & Family Social Work: "Accessibility of transportation to child-welfare involved parents and the related impact on court-ordered service participation.

The article explores the impact of transportation access on child welfare-involved families' service participation. 

Families involved with Child Protective Services (CPS) face daunting steps to meet their service plan goals in the effort to achieve reunification with their children. Families who lack transportation access face additional barriers. This study explored Court Appointed Special Advocates, or CASA, volunteers' perspectives of these barriers. Semi-structured interviews were conducted with nine CASA volunteers, with questions regarding volunteers' experiences of transportation access for parents and children. Primary emphasis was placed on families' access to services. Three primary themes emerged in the data analysis:

  1. challenges are wide-ranging, exacerbated by transportation issues;
  2. transportation linked to court-ordered services success; and
  3. practical...
