Final ReportIn the new mobility-as-service context, we envision that traditional system design principles of transit services shall be revisited to improve the overall system effectiveness. In this report, we will develop methods to quantify the effectiveness of a transit system, where private mobility services coexist, by measuring costs, social equity, environmental benefits etc. gained from active lifestyle. A real-world case study has been implemented to learn design and policy insights. While conducting this research, we also realized that the transit demand of a study area is often not available due to missing data. Since this is an important input for any network-based transit system design model, we also developed a method to infer missing transit demand via combing statistics and network modeling techniques.U.S. Department of Transportation 69A355174711
