【摘要】：随着我国经济的持续快速发展,交通需求的增长速度明显高于道路资源增长的速度,我国许多大城市面临着日益严重的交通拥堵问题。公共交通作为运输效率极高的交通方式,是解决城市拥堵问题的一个重要的方式,公交优先也成为了国内外交通学者的研究热点。本文将以城市主干道为研究对象,研究如何通过信号控制的方法实现公交优先。 本文所做的工作包括以下几个方面： 1、对公交优先的信号控制的基础理论进行了全面的研究,重点阐述了被动优先及主动优先两种优先控制策略的实现方法,作为本文研究的理论基础。 2、以城市主干道为研究对象,对被动式线控系统中的几个关键参数——周期、绿信比和相位差进行研究,以人均延误最小为目的,加入公交优先作为控制条件,建立各个参数的优化模型,得出基于公交优先的城市主干道信号控制优化方案。在此控制方案基础上,引入公交车组的理论,建立公交车辆的优先规则,在交叉口中对公交车采用主动优先的方法,在对协调控制系统影响较小的情况下对公交车辆实施主动优先。 3、以中山市中山路为仿真对象,建立两套仿真优化控制方案,在VISSIM软件中对本文提出的公交优先信号协调控制方案及公交车组的实施效益进行评价。
[Abstract]:With the continuous and rapid development of China's economy, the growth rate of traffic demand is obviously higher than that of road resources, and many large cities in China are faced with increasingly serious traffic congestion problems. As a highly efficient mode of transportation, public transport is an important way to solve the problem of urban congestion. Public transport priority has also become a research hotspot of domestic and foreign traffic scholars. This article will take the city main road as the research object, study how to realize the bus priority through the signal control method. The work done in this paper includes the following aspects: 1. The basic theory of bus priority signal control is studied comprehensively, and the realization methods of passive priority and active priority are emphasized. As the theoretical basis of this paper. 2. Taking the city main road as the research object, the paper studies several key parameters in the passive line control system-cycle, green signal ratio and phase difference. In order to minimize the delay per capita, bus priority is added as the control condition, and the key parameters of the passive line control system are studied, which are the cycle, the green signal ratio and the phase difference. The optimization model of each parameter is established, and the signal control optimization scheme of urban trunk road based on bus priority is obtained. On the basis of this control scheme, the theory of bus group is introduced, the priority rule of bus is established, and the active priority method is adopted to the bus in the crossing port. In the case of small impact on the coordinated control system, active priority is given to public transport vehicles. Thirdly, taking Zhongshan Road in Zhongshan City as the simulation object, two sets of simulation optimization control schemes are set up, and the coordinated control scheme of bus priority signal and the implementation benefit of bus train set are evaluated in VISSIM software.
