摘要: 利用路段传输模型研究了先进出行者信息系统(ATIS,Advanced Traveler Information System)环境下的可变信息板(VMS, Variable Message Signs)选址问题.提出一种路段行驶时间预测方法,用于车载ATIS的信息发布.数值模拟结果表明,ATIS渗透率存在一个临界值,低于该值时,VMS的位置应随着渗透率的增加远离路口,高于该值时,VMS的位置应靠近路口.结合ATIS渗透率确定VMS位置,能够减小系统总拥挤延迟.该方法有助于理解多种交通信息共同作用下的驾驶员路径选择行为和评价VMS位置对系统性能的影响.

Abstract: The variable message signs (VMS) location problem under the advanced traveler information system (ATIS) environment was studied using the link transmission model. A method for estimating link travel times was proposed for serving the information release of ATIS. Simulation results show that there exists a critical value about the ATIS market penetration. The VMS should be located more away from the intersection with the increase of the ATIS market penetration when the penetration is less than the critical value, closer to the intersection otherwise. It is also shown that the total congestion delay of the system can be further reduced if determining the VMS location with consideration of the ATIS market penetration. This method can help well understand the drivers’ route choice behavior under multiple traffic information and evaluate the impact of VMS location on system performance.
