Hierarchical taxi dispatch system with local coordination among micro-level components: WIP abstract

Taxi drivers face to poor working conditions such as low wages and long working hours. To improve the conditions, a taxi dispatch system is very important. F. Miao et al. proposed a method for calculating an optimal taxi cruising path based on the model predictive control and the new parameter of supply demand ratio [1]. T. Ushio et al. proposed a method for calculating an optimal taxi cruising path based on a mixed logical dynamical model [2]. X. Chen et al. proposed a hierarchical taxi-dispatch system consisting of global and regional decision-makers [3]. The global decision-maker calculates the optimal taxi dispatch in a longer time period, while the regional ones determine schedules of taxis in the corresponding regions in a shorter time period. However, these previous mechanisms have lower scalability and real-time properties. To tackle these problems, we propose a novel hierarchical support system for a taxi dispatch system. In our proposal, a macro level component calculates the optimal taxi movement by using a taxi flow model, whereas micro level components determine the optimal taxi cruising in the corresponding regions. Both of them are conducted in the same time period.
