出行信息公开对出租车交通系统运行的影响

基于仿真研究乘客出行信息公开程度对出租车交通系统运行效率的影响.将乘客出行信息公开程度划分为出行信息未公开,全公开,半公开模式;制定路网搭建,乘客生成与退出,出租车与乘客匹配,出租车行驶规则;模拟出租车搜索、匹配、搭载、送达乘客过程;分析不同信息公开程度对出租车空驶率,乘客候车时间,送达人数,司机平均收益等的影响.研究表明,仅公开出发地信息的半公开模式有助于提高出租车交通系统运行效率与服务质量,且有效地避免由于出租车司机有意选择高收益乘客而造成“隐形拒载”低收益乘客问题.为保证每位出行者的公平性,建议采用仅公开出发地信息的出行信息半公开模式.

Influence of Travel Information Release on the Operation of Taxi Transportation System

The influence of travel information release on the efficiency of taxi transportation system is studied based on simulation. The release degree of travel information is divided into three types mode: the no-release, the full- release and the half- release information. This paper formulates road network construction rules, passenger generation and disappearance rules, taxi and passenger matching rules, taxi driving rules, taxi system evaluation rules. It is simulated that the running process of taxis searching, matching, carrying and delivering passengers. Analyzing the impact of different information disclosure on taxi vacancy rate, passenger waiting time, number of passengers, average driver income. It is found that the half-release mode with only the origin site information can help improve the taxi transportation system operation efficiency and service quality. Compared with the other two modes, because of taxi-drivers only knowing the passengers' origin position, the half-release mode effectively not only improve the efficiency of the taxi driver searching travel passengers, but also avoid the "invisible refuse" problem arised from taxi driver deliberately chosing the passengers who bring higher benefits. In order to ensure the equity of every passengers, it is recommended to adopt the half- release mode with only the origin site information in taxi transportation system.
