Research on Routing Optimization Model of Demand Responsive Connector under Simultaneous Pickup and Delivery Mode

With the continuous progress of urbanization, the phenomenon of urban suburbanization and the separation of work and housing is becoming increasingly obvious. Due to the low passenger flow density in the suburbs and the poor operation effect of conventional public transportation, there is an urgent need to find a rail transit bus operation mode that is suitable for low passenger density areas such as urban suburbs. Demand Responsive Connector (DRC) is a transportation mode that adopts "online booking and offline travel" to meet the needs of passengers. This paper will focus on the DRC route optimization problem under the simultaneous pick-up mode. This paper analyses the DRC path optimization problem under the single transfer point simultaneous pick-up mode, defines the research situation, proposes the modelling idea, considers the balance of the interests of both passengers and enterprises, and establishes the DRC path optimization model under the single transfer point simultaneous pick-up mode with the goal of maximum passenger satisfaction and minimum enterprise operating cost. According to the characteristics of the model, a multichain chromosome genetic algorithm is designed to solve the model.
