汽车预期轨迹驾驶员模糊决策模型及典型路况仿真

本文分析了预瞄最优曲率模型的特点。在此基础上应用系统模糊决策理论,通过合理的预期轨迹决策策略,建立了驾驶员动态决策汽车预期行驶轨迹的模糊决策模型。最终仿真计算了驾驶员在多种典型路况下对汽车预期轨迹的决策行为。

动态路径推荐算法在城市智慧交通技术中的应用

近年来,城市异常拥堵的交通已对人们的日常出行造成了很大困扰,这一现实情况为人工智能技术在智能交通领域当中的应用提供了良好的契机。主要探讨引入动态路径算法,对城市交通带来的影响,通过仿真实验得知,城市交通状况预测模型表现相对传统模型更加优秀,再利用动态路径推荐算法可以最大程度节约行驶时间,而且在20×20的栅格粒度情况下,节约率恒定,这样可以证实算法和模型的有效性。

Modeling for Action of Recovering from Erroneous Driving Condition Based on Revised Decision Tree

Driving behavior modeling is very important in the research area of road traffic systems safety analysis. The characteristics of action of recovering from erroneous driving condition underlying road traffic accident or incident scenarios is quantitatively analyzed, the model of action of recovering from erroneous driving condition is set up according to the identification of erroneous driving condition and the measurement of correction from erroneous driving condition. And then, the probability of action of recovering from erroneous driving condition has been measured based on a revised decision tree. The measure process uses a combination of test data and subjective judgments of driving behavior. It can provide a very helpful theoretical basis for the further analysis of driving behavior in road traffic system.
