Research Highlights
Evaluation of Road User Comprehension and Compliance with Red Colored Transit Priority Lanes

Jennifer Dill , Nathan McNeil
As part of the City of Portland Enhanced Transit Corridors Plan, the Portland Bureau of Transportation (PBOT) is working with TriMet and Jacobs Engineering to evaluate the impact of red colored transit priority lanes at key locations in and around downtown Portland. Transit priority lanes restrict access to certain lanes, prioritizing transit movement, while sometimes allowing for other users or specific actions - for example shared bus and bike lanes, or shared bus and right-turn lanes. Red ...

The new Social-Transportation Analytic Toolbox (STAT) for Transit Networks, developed by NITC researchers in a multi-university collaboration, is a dynamic platform that combines Twitter, general transit feed specification (GTFS), and census transportation planning products (CTPP)—in this case, job density data—to help agencies evaluate overall system performance and identify connectivity gaps. It can also act as a decision support tool for recommending service improvements. The STAT is an o...
