“…They assumed that agencies were responsible for all service costs and made vehicle assignments in response to incoming requests. Typically, the costs considered in the optimization include the agency's operating costs (distance traveled, fleet size, labor) and the user's time cost (waiting time and in-vehicle time) (Quadrifoglio & Li, 2009;Nourbakhsh & Ouyang, 2012;Grahn, et al, 2022). Other studies focused on users' costs.…”

Traditional fixed-route transit services are inefficient in low-density areas due to limited and dispersed service demand. Many transit agencies look for effective alternatives to provide adequate transportation services in these areas, especially by leveraging mobile ICT-enabled new mobility services. This study evaluates the cost-effectiveness of transit incorporating mobility-on-demand (TIMOD) compared to fixed-route bus transit, driving, and commercial ride-hailing services in suburban areas. It extends a comprehensive analytical framework to evaluate the cost-effectiveness of TIMOD and other alternatives from a societal perspective by considering transportation externalities. The analysis accounts for travelers’ monetary and time costs, service providers’ operating costs, and external costs to society. Using real-world data from a TIMOD program, Metro Flex, in the Seattle region and estimates based on simulation, the study compares the economic cost of TIMOD trips with counterfactuals by other travel modes within two separate suburban case areas. The results indicate that, in our study areas, TIMOD trips have a total generalized cost for travelers that is higher than driving but lower than fixed-route transit trips and ride-hailing trips, owing to its on-demand nature coupled with subsidized fare. Compared to TNCs, TIMOD’s more common shared rides contribute to its lower external costs by reducing vehicle miles traveled per person. Adding service operation, TIMOD in the suburban areas becomes less cost-effective due to high operating costs. However, the disparity is slight in comparison to fixed-route transit. Our findings also show that areas with higher population densities result in lower operation costs per rider of TIMOD. Riders living in higher income areas with lower population densities and more limited transit services benefit more from TIMOD services with a higher reduction in travelers’ generalized cost compared to fixed-route transit. The study highlights the potential benefits and tradeoffs of providing TIMOD services in suburban areas, shedding light on the conditions under which such services are economically competitive.

In this paper, to improve the operational service capability and attractiveness of the flex-route transit system, the real dynamic interaction scenario between passenger travel choice preference and system operation scheme in the post-pandemic era is described and quantified. The key technologies, operation mode, system framework, and interactive events required for dynamic interactive scheduling and route planning of flex-route transit are summarized. According to different choice preferences, the corresponding dynamic interaction scheduling strategies and route mixed integer programming model are proposed. An optimization scheme to improve the service capability of the system is introduced and analyzed. The computational results based on real-world cases show that the proposed strategy can better handle the relationship between requirements of transit system operation and requests of passengers without increasing operating costs, significantly improving the service performance of flex-route transit and the choice rate of passengers. We also find that the introduction of optimization schemes and the adjustment of passenger fares constitute a win-win strategy that benefits both passengers and transit operators.
