Previous literature has recommended that transit agencies actively build partnerships with mobility service companies from the private sector, yet public transit agencies are still in search of a solid empirical basis to help envision the consequences of doing so. This study presents an effort to fill this gap by studying a recent experiment of shared mobility public-private partnership. The carpool incentive fund program launched by King County Metro in the Seattle region. This program offered monetary incentives for participants who commuted using a dynamic app-based carpooling service. Through descriptive analysis and a series of logistic regression models, we found that the monetary incentive to encourage the use of app-based carpooling generated some promising outcomes while having distinct limitations. In particular, it facilitated the growth of carpooling by making carpooling a competitive commuting option for long-distance commuters. Moreover, our evidence suggested that the newly generated carpooling trips mostly substituted for single-occupancy vehicles, thus contributing to a reduction of regional VMT. The empirical results of this research not only will help King County Metro devise its future policies but also highlight an appealing alternative for other transit agencies in designing an integrated urban transportation system in the era of shared mobility

Supplementing Fixed-Route Transit With Dynamic Shared Mobility Services: A Marginal Cost Comparison Approach

69A3551747110Transit agencies in the U.S. have shown great interest in the possibility of incorporating on-demand shared mobility modes into their transit services. However, the cost-effectiveness of on-demand modes has not been clearly demonstrated, and there is no effective method for transit agencies to compare the costs of different service options. This study developed an innovative, economic-theory-based framework that appropriately conceptualizes the economic costs of incorporating on-demand service options into transit. On the basis of a theoretical framework, the study built a simulation model and applied it to evaluate an existing pilot of a transit-supplementing, on-demand mobility service: Via to Transit in the Seattle region. By accounting for both the service provider\u2019s cost and the users\u2019 costs, we obtained a more complete and accurate measure for the cost advantages of offering the on-demand option in comparison to expanding fixed-route transit. The theoretical framework and the simulation model can support the decision-making of public transit agencies as they explore leveraging on-demand shared mobility to supplement traditional transit
