People and parcels sharing a taxi for Tokyo city

Abstract

This paper introduces a practical hybrid transportation model for Tokyo city that allows a passenger and parcels are handled in a same taxi. We inherit the recent model given by Li et al. in 2014 and make it much more realistic by adding some constraints related to the real-life case. We propose the time-dependent model to facilitate formulating constraints. The feasibility and the efficacy of the model are proved by two proposed heuristic algorithms. Especially, we use the real-case experimental data set recorded by Tokyo-Musen Taxi company. The data set includes more than 20,000 requests per day, more than 4,500 served taxis per day and more than 130,000 crossing points on the Tokyo map. The experimental results are analyzed on various factors such as the total benefit, the accumulating distances during the day, the number of used taxis and the number of shared requests.
