While transit agencies tend to focus on ridership as a measure of performance, this can skip over an important aspect of the agency’s… Read More

Social-Transportation Analytic Toolbox (STAT) for Transit Networks

Xiaoyue Cathy Liu Ran Wei , Aaron Golub , Liming Wang
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… Read More
