Abstract
In order to improve traditional safety distance models based on braking process of the leading vehicle, a new safety distance model of one-lane following condition is established based on traditional safety distance models. The new model considers the relative speed between vehicles and the change process of deceleration value. A simulation using Matlab software verifies that the new model overcomes inaccurate defects in computing safe-distance of the traditional models. Finally, we established an intersection traffic-wave simulation system using Visual C++ 6.0 as the software platform. Simulation results demonstrate that the new model produces better safe-distance prediction between vehicles. Hence, it improves road-use efficiency, reduces vehicle pollution and intersection delays under condition that the safety distance production is ensured. The new model can provide new ideas for control of signalized intersection.
为了改进传统的基于前车制动过程的安全距离模型,在传统安全距离模型的基础上,建立了一种新的单车道跟随安全距离模型。新模型考虑了车辆间的相对速度和减速度值的变化过程。利用Matlab软件进行了仿真,验证了新模型克服了传统模型计算安全距离不准确的缺陷。最后,以Visual c++ 6.0为软件平台,建立了一个十字路口交通波仿真系统。仿真结果表明,该模型能较好地预测车辆间的安全距离。在保证安全距离产生的前提下,提高道路使用效率,减少车辆污染和交叉口延误。该模型可为信号交叉口的控制提供新的思路。
