Abstract

This paper designed a linear time insertion operation method to overcome defects of the existing insertion operation methods with the high time complexity and the low operation efficiency in the dynamic ridesharing system. With the optimization objective of minimizing the vehicle detour distance, the proposed method addressed the dynamic carpooling route optimization problem considering the passengers' boarding and alighting time constraints and vehicle capacity limitation. It constructed a dynamic ridesharing route model. By using the dynamic programming technology and the strategy of fixing the insertion position of the source node, as well as the calculation results of the location vector, the insertion position of the target node with the minimum vehicle detour distance could be found with a constant time. Theoretical analysis shows that the method can find the best insertion position of source node and target node in linear time. The simulation results show that the method can quickly get the optimal ridesharing route, and significantly improve the operation efficiency of dynamic ridesharing system.
