Evaluation framework for an efficient commuting carpool program

Abstract

Hundreds of cities have already pledged to get to “net zero” by 2050. MaaS (Mobility as a Service) is a one of promising measures but commuting carpool program seems to be effective for concentrated commuting to factories in suburban areas where public transportation is insufficient. The commuting carpool is easy to understand as a service, but there are considered many parameters for designing it. Especially companies in Japan have a big role to implement its service because collaborations with public and private sectors are not sufficient viewpoint of carpooling infrastructures and financial supports. In this study, we propose an evaluation framework for companies with two phases: Basic design to make a decision for implementation through the feasibility studies, and Detailed design and Improvement to consider detailed implementation.We focus on practical evaluation framework for Basic design and conduct a case study on commuting to a newly constructed factory. We apply it to extract parameters which are necessary for the feasibility study. As for the effect of the introduction of the program, its service is able to reduce the number of vehicles by 30-66% and CO2 emissions by 373-800 tons per year.
