Project summary:

The general public and many stakeholders are interested in the A line, the first arterial bus rapid transit (BRT) line in the Twin Cities. A comprehensive study of the A Line experience will demonstrate its benefits, shortcomings, and opportunities for further improvements. This study aims at providing a deeper understanding of the operational aspects of the A Line, travel behavior of users, and perceptions of users and nonusers. From the operational perspective, transit dwell time is being calculated from vehicle location data, and the impact of dwell time on road capacity is being estimated using traffic flow models. Moreover, video data is being collected and processed to estimate traffic measures (such as capacity reduction and delay) in order to understand the impact of transit vehicles on general vehicle traffic in the corridor. Regarding perceptions, the study is using Metro Transit's rider survey to understand users' demographics, travel behavior, and perception of the A Line in comparison with other transit routes. The study is also conducting field surveys to capture the perception of nonusers (such as residents and business owners) on the corridor, understand A Line's strengths, weaknesses, opportunities, and threats, and make recommendations for future BRT lines.
