【摘要】：为验证优化速度模型和广义力模型在模拟信号交叉口停车跟驰行为方面的适应性,在试验分析基础上提出考虑信号灯作用的跟驰模型,分别基于现有优化速度模型和广义力模型构建模拟系统对信号交叉口的停车跟驰行为进行仿真,分析其存在的问题及原因;采用实测数据标定广义力模型的参数,分析标定后模型的适应性;通过试验分析构建信号交叉口停车跟驰模型需考虑的因素并构建1个新的跟驰模型。结果表明:现有优化速度模型不适合描述信号交叉口的停车跟驰行为;重新标定的广义力模型仍存在倒车问题;新提出的跟驰模型能够避免倒车问题且能够很好地拟合实测数据。
[Abstract]:In order to verify the adaptability of the optimal velocity model and the generalized force model in simulating the stopping and car-following behavior at signalized intersections, a car-following model considering the effect of signal lights is proposed on the basis of experimental analysis. Based on the existing optimal speed model and generalized force model, the simulation system is constructed to simulate the stopping and car-following behavior of signalized intersection, and the existing problems and reasons are analyzed, and the parameters of the generalized force model are calibrated by the measured data. The adaptability of the calibrated model is analyzed. The factors to be considered in the construction of signalized intersection stopping and car-following model are analyzed and a new car-following model is constructed. The results show that the existing optimal speed models are not suitable to describe the stopping and car-following behavior of signalized intersections. The recalibrated generalized force model still has the problem of reversing the car, and the new car-following model can avoid the problem of reversing and fit the measured data well.
