Pedestrians often have to wait longer than drivers for the light to change. Increased delay for pedestrians can lead to noncompliance, which can have a negative impact on safety.

Most planning efforts geared toward those on foot have tended to focus on safety, but pedestrian efficiency is also important.

NITC researchers will present on this topic at the annual meeting of the Transportation Research Board in Washington, D.C. Learn more and download our guide to the conference.

Sirisha Kothuri, a research associate in civil engineering at Portland State University, is the principal investigator on this NITC research project, an extension of her doctoral dissertation work.

Kothuri and co-investigator Edward Smaglik of Northern Arizona University will present their work Sunday, Jan. 8 in a workshop at the TRB conference. Their research looked at pedestrian strategies around the country to determine if they were primarily safety or efficiency measures.

“Generally, pedestrian strategies, if they exist at all, are safety based,” Kothuri said.

So the first task was to identify efficiency-based strategies for pedestrians. Then the research team undertook a...
