摘要:
为了最大限度地利用交叉口的时空资源,以Ring-Barrier相位模式为基础,建立了交叉口信号配时与进口车道功能划分协同优化的数学模型.该模型是一个常规的整数非线性规划模型,目标函数是整个信号交叉口的车均延误最小,连续变量包括周期时长和各相位的绿灯时长,整数变量是交叉口各个进口处不同转向运动的车道数量.根据该模型的特点,给出了分支定界的解法.选取南京市一个交通繁忙的信号交叉口进行实地调查,采集了信号配时和车道功能划分等相关数据,并采用VISSIM仿真软件对该路口的优化效果进行评价.结果表明,相比常规的优化模型,该协同优化模型可以将交叉口的车均延误减少20.01%,周期时长缩短18.15%.
Abstract:
In order to make full use of time and space resources of intersections, a mathematical model of collaborative optimization of signal timing and lane marking is proposed based on the Ring-Barrier phase pattern. This model is formulated as a conventional mix-integer-nonlinear-program(MINLP), and the average delay minimization problem is considered. The continuous variables include the cycle length and green times for traffic movements, whereas the integer variables include the lane numbers of different movements on all approaches of intersection. A branch-and-bound algorithm is proposed to solve this problem. A site survey is conducted to collect all relevant input data including the existing lane timing and signal setting at a busy intersection in Nanjing city. The different optimization models are evaluated by the simulation software of VISSIM. The results show that compared with the conventional optimization model, the average delay of the collaborative optimization model can be reduced by 20.01% and the cycle length can be shortened by 18.15%.
