Abstract

This paper proposes the Advanced Demand Signals scheme (ADS) that is a traffic signal control scheme by vehicle demands, and evaluates its performance. Each vehicle in some range transmits the relative distance between the vehicle and the intersection using seamless and real-time road-to-vehicle communications. The traffic signal decides the light according to the demand that is calculated using the transmitted data. Performance evaluations are carried out using the simulator including three intersections with traffic signals. This simulator uses the average idling time as a performance index, and examines the basic performance effect of communication range, and effect of performance function. Consequently, it is shown that the ADS scheme is effective in almost all vehicle densities, and, in particular, the ADS scheme shortens the average idling time more than by a maximum of 90% compared with the most basic conventional control scheme with low vehicle density.
超前需求信号计划的影响
提出了一种基于车辆需求的交通信号控制方案——高级需求信号方案,并对其性能进行了评价。在一定范围内的每辆车都使用无缝和实时的路对车通信传输车辆与十字路口之间的相对距离。交通信号根据传输数据计算出的需求来决定信号灯。利用仿真器对三个具有交通信号的十字路口进行了性能评估。该模拟器以平均空转时间为性能指标,考察了通信距离的基本性能影响和性能函数的影响。结果表明,ADS方案在几乎所有车辆密度下都是有效的,特别是与最基本的传统低车辆密度控制方案相比,ADS方案的平均空转时间缩短了90%以上。
