Title:

Evaluating the Impact of a Newly Added Commuter Rail System on Bus Ridership: A Grouped Ordered Logit Model Approach

Accession Number:

Record Type:

Component

Abstract:

This study examines the impact of new transit investments (such as an addition of commuter rail to an urban region) on existing transit infrastructure (such as the traditional bus service present in the urban region). Specifically, the study develops a comprehensive and statistically valid framework to study the impact of new public transportation infrastructure (SunRail) on existing public transit infrastructure (Lynx) in the Orlando metropolitan region. The data for the study is drawn from bus ridership information for six 4-month time periods - 3 prior to installation of SunRail and 3 after installation of SunRail - allowing us to study time varying effects of SunRail system on ridership. The current research formulates and estimates an innovative grouped ordered response model structure for the ridership analysis. The proposed model accommodates for common unobserved factors affecting boarding and alighting as well as repeated measures for each stop. To measure the impact of commuter rail on stop level bus ridership (defined as boarding and alighting), the model system controls for a host of exogenous variables including stop level attributes, transportation infrastructure variables, transit infrastructure variables, land use and built environment attributes and sociodemographic and socioeconomic variables. The results while highlighting the impact of the exogenous variables provide strong evidence of the positive impact of SunRail system on the ridership. Furthermore, the influence of SunRail on ridership has a positive temporal trend indicating the strengthening of the impact with the time of operation, a healthy metric for potential future expansion.
