Multimodality incentivized by employer-based travel demand management

Abstract

ABSTRACT This study explored the effectiveness of various employer-based travel demand management strategies in promoting multimodality and mode substitution among employees in Washington state using a mixed multinomial logit model. The study found that employee transportation coordinators played an important role in encouraging the use of sustainable travel modes. Spatial analysis revealed that individuals who lived and worked in proximity were more likely to adopt multimodal transportation. The study also highlighted the convenience of driving alone and the lack of information on sustainable alternatives as two major barriers to the adoption of sustainable transportation modes and recommended educational campaigns to increase awareness. To inform practice, this study identified transit subsidies, parking pricing, and work schedule flexibility as the most effective TDM strategies to promote multimodality and mode substitution, followed by compressed workweeks, and providing easy access to transit and amenities.
