This research aims to evaluate the positive impacts of deploying OneBusAway, which is a suite of tools that provide real-time bus arrival information through mobile and web applications. OneBusAway was originally developed in Seattle as open source software, and this project conducts a small-scale deployment in Tampa, Florida on the Hillsborough Area Regional Transit (HART) bus system. In the spring of 2013, approximately 250 HART bus riders participated in a pilot program to evaluate the impacts of OneBusAway. Prior to the launch of OneBusAway, these riders completed a “before” web-based survey that included questions about travel behavior, such as frequency of transit travel, waiting times, and transfers, and attitudinal questions pertaining to safety and overall transit service. OneBusAway was then provided to half of the riders (the user group), and it was not given to the other half of riders (the control group). Three months later, both the user and control groups completed an “after” survey to assess their changes in behavior and attitudes due to OneBusAway. We present results from these surveys and accompanying statistical analyses to assess the impacts of this transit traveler information system on bus riders.
