摘要
本文对列车追踪安全距离优化算法进行研究。分析原有安全距离模型的原理及制动最不利情况算法。为缩短安全间隔,基于原有安全距离模型,给出增加前行列车速度信息来计算安全距离的优化算法,并对此进行可行性及安全性分析,该算法是考虑前行列车最有利情况下制动与后行列车最不利情况下制动的一种安全距离模型优化算法。通过仿真研究,对原有算法与优化算法的安全距离模型进行比较。结果表明:优化算法与原有算法相比,能够有效地缩短最小安全间隔,提高列车通过能力。
The algorithm for optimization of the safe distance between running trains was studied .The principle of the original model of the safe distance between running trains and the algorithm applicable to the most un-favourable braking cases were analyzed .On the basis of the original model of the safe distance between running trains ,in order to shorten the safe distance ,the optimization algorithm was given by which the information of preceding train speeds were increased to calculate the safe distance .Braking of the preceding train in the most favourable conditions and braking of the following train in the most unfavourable conditions were taken into consideration .Feasibility and safety of the potimization algorithm were analyzed .The optimization algorithm was verified by simulation .The results show that the optimization algorithm is effective to shorten the safe headway and improve the passing capacity .
