本发明公开了一种智能车路协同环境下实时可变车道动态分配方法,该方法基于BPR函数构建路段动态车道分配模型,为了体现实时动态转换,将全天24个小时划分为若干阶段,获取各个阶段的交通量和行驶阻抗,并将它们的乘积在时间上作积分,最终选择每个阶段中最小延误的车道组合作为最优方案。其中的交叉口动态车道分配模型是基于HCM2000延误模型来构建,以交叉口车均延误最小为目标函数,通过对不同流量状态下的不同车道组合的车均延误进行分析,寻找最优车道组合,并通过算例分析和MATLAB计算对模型进行验证。本发明实时可变车道动态分配方法可有效分配道路资源,降低行车延误。
The invention discloses a real-time variable lane dynamic allocation method in an intelligent vehicle-road cooperative environment. According to the method, a road section dynamic lane distribution model is constructed based on a BPR function, and in order to reflect real-time dynamic conversion, 24 hours of a day are divided into a plurality of stages, the traffic volume and the driving impedanceof each stage are obtained, the product of the traffic volume and the driving impedance is integrated in time, and finally, the lane combination with the minimum delay in each stage is selected as anoptimal scheme. An intersection dynamic lane distribution model is constructed on the basis of an HCM2000 delay model, the minimum average vehicle delay at the intersection is taken as an objective function, the optimal lane combination is searched for by analyzing the average vehicle delay of different lane combinations in different flow states, and the model is verified through example analysisand MATLAB calculation. The real-time variable lane dynamic allocation method can effectively allocate road resources and reduce driving delay.
