【摘要】 为了解决学术界关于安全车距的理论值和实际道路情况观测值的巨大差异,通过建立新的跟驰模型,精确模拟车辆之间的跟驰行为,使模型更符合车辆在道路上的实际情况,并得出可供驾驶员实际操作的安全车距参考值;结合优秀驾驶员的经验,提出了具有指导性的保持安全车距和换道、刹车的一体化流程再造;探讨了安全车距的区间和极限情况,并提出了缩短安全车距的可靠办法,提高了道路利用效率。实证数据也验证了其结论具有广泛的适用性。更多还原

【Abstract】 In order to solve the enormous differences about safe headway between the theoretical value from academic researches and the observational value from practical road conditions,a new vehicle-following models is established to accurately simulate the vehicle-following process,which conforms to the actual situation much better,and an operable reference value could be deduced for car drivers.Combined with the experiences of outstanding drivers, an integrated process reengineering including maintaining safe headway and changing traffic lane or braking is put forward as guidance.In addition,the limit of safe headway is discussed,the reliable measures are found,so the safe headway could be shortened to improve the efficiency of road utilization.Empirical data also verify that its conclusion has the extensive applicability更多还原
