A multimodality index (MI) is developed to evaluate the accessibility and convenience of transit use by investigating the connectivity of a Bus Rapid Transit (BRT) with other modes of travel. Better connected stations increase transit system ridership, resulting in environmental and social equity gains. The integration of the Orange Line BRT system in Los Angeles with other travel modes, including bicycles, pedestrians, regular buses, and private automobiles, was analyzed using field observations and LA Metro data to create a multimodality index (MI). While multimodal connectivity of the Orange Line BRT system varies across stations, a positive relationship exists between ridership and the MI, indicating that the MI is a reliable predictor of transit ridership and a useful tool for transit planning.
