How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit?

The project was led by Yao Jan Wu, director of the Smart Transportation Lab at the University of Arizona. Co-investigators were Xianfeng Terry Yang of the University of Utah, who researches traffic operations and modeling along with connected automated vehicles, and Sirisha Kothuri of Portland State University, whose research has focused on improving signal timing to better serve pedestrians. Join them on Sept 15, 2021 for a free webinar to learn more.

"We want to improve mobility for all users, be it pedestrians, vehicle drivers or transit riders, and there are different strategies to do this. How do we harness data to drive us to these strategies?" Kothuri said.

Funded by the National Institute for Transportation and Communities (NITC), this multi-university collaboration addressed the question from three angles:

  • Wu and his students in Arizona looked at the impact of speed management strategies on conventional roadways...

Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.

Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.

Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and modeling

The tour highlighted research projects funded through U.S. DOT’...

Webinar: Improving Walkability at Signalized Intersections with Signal Control Strategies

The goal of signal timing at an intersection should be to maximize efficiency for all users. In many jurisdictions, however, traffic signals are timed mostly with the goal of reducing vehicular delay.

Other road users, such as pedestrians, deserve similar focus. In legacy transportation...
