【摘要】：道路上的潮汐现象使得城市的交通拥堵更加严重,这种现象给驾驶人及行人的出行和生活造成很大程度上的不便。为了缓解潮汐式交通现象带来的交通问题,提高路段与交叉口的利用率,寻找解决潮汐式交通问题的措施刻不容缓。本文在全面了解可变车道的研究理论和方法,并加以总结和概括的基础上。探究了产生潮汐式交通的原因,分析了潮汐交通的特性,提出了缓解潮汐交通问题的方法,即利用可变车道来实现分时段合理的转换,利用信号控制系统、可变指示牌等基础设施的引导,对于目前来说是一种有效的缓解潮汐式交通问题的有效方法。潮汐式可变车道包括行驶方向可变车道和导向式可变车道。本文研究了可变车道的优化控制方法,并且以大连市中南路为行驶方向可变车道的例子,建立基于道路行驶阻抗的车道优化模型,确定了设置可变车道的步骤,得出具体方案。另外,以鞍山市园林路工农街路口和二一九公园交叉口为研究对象,论述了可变车道设置的现实可行性。最后,应用VISSIM软件对路段上的行驶方向可变车道和交叉口的导向式可变车道设置可变车道前后分别进行了仿真。对设置行驶方向可变车道前后得到的车速进行对比,对设置导向式可变车道前后得到的延误、停车时间、停车次数的数据进行分析,结果表明：合理利用可变车道可提高路段上的车速,降低交叉口延误、停车时间以及停车次数的指标,从而提高了路段与交叉口的通行能力。最后总结了本文研究的主要内容,和对相关研究的展望。
[Abstract]:The tidal phenomenon on the road makes the traffic jam in the city more serious, which causes great inconvenience to the travel and life of the driver and the pedestrian. In order to alleviate the traffic problem caused by the tidal traffic phenomenon, It is urgent to improve the utilization ratio of road sections and intersections and to find solutions to tidal traffic problems. On the basis of summing up and summarizing, this paper probes into the causes of tidal traffic, analyzes the characteristics of tidal traffic, and puts forward a method to alleviate the problems of tidal traffic, that is, to use variable lanes to realize reasonable conversion in different periods. The use of signal control systems, variable signs and other infrastructure guidance is an effective way to alleviate tidal traffic problems. The tidal variable lane includes the variable direction lane and the steering variable lane. This paper studies the optimal control method of the variable lane, and takes the Zhongnan Road in Dalian as an example of the variable lane in the driving direction. A lane optimization model based on road impedance is established, the steps of setting variable lane are determined, and the concrete scheme is obtained. In addition, taking the intersection of Gongnong Street and 219 Park in Anshan City as the research object, The feasibility of variable lane setting is discussed. Finally, VISSIM software is used to simulate the driving direction variable lane and the leading variable lane of the intersection before and after setting the variable lane. The speed before and after the setting of the variable direction lane is compared. The data of delay, stopping time and stopping times before and after setting up the variable lane are analyzed. The results show that the reasonable use of the variable lane can increase the speed on the road and reduce the delay at the intersection. The index of parking time and number of stops improves the traffic capacity of road sections and intersections. Finally, the main contents of this paper and the prospects for related studies are summarized.
