Abstract: The operation characteristics of urban taxis were distinguished from those of traditional cruise mode with the information provided by taxihailing apps. In order to accurately calculate the average passenger’s waiting time in each zone, the traffic zones were divided into saturation zone, instauration zone and equilibrium zone according to the relationship of arrival and departure quantity of load taxis firstly. And then, the distribution matrix of vacant taxi could be forecasted, considering the effect produced by information condition on searching behavior. Finally, the model of passenger’s average waiting time in each zone was established, according to the equilibrium relationship between taxi single vacant time and passenger’s single waiting time. In the numerical experiment, comparing with the equilibrium model in traditional background, the influence of taxihailing apps on the passenger’s waiting time in different zone was different in the same network. The passenger’s single average waiting time was reduced by 65% in saturation zone and equilibrium zone. However, it was increased by 23% to 58% in instauration zone; meanwhile, taxi unloaded ratio in this zone was reduced. The calculation results reveal that taxhailing apps contribute to information transparency, reduce taxi unload ratio and have certain effect on passenger’s waiting time, which could offer some beneficial guidance and theoretic basis to the planning and management of urban taxihailing apps.
