基于流体动力学方程的行车时间估计模型不能很好地反映真实的行车时间,需要对其进行一定的改进.在对交通流进行流体动力学建模的基础之上,引入对高速公路路网中不同路段之间的行车时间相关性和同一路段不同季节、不同时段的行车时间相关性分析,建立了带时空相关性分析的时间估计模型,使用统计学的方法消除动力学模型的误差. The driving time estimation model based on fluid dynamics equations can not reflect the real driving time well, and some improvements are needed.On the basis of hydrodynamics modeling of traffic flow, The correlation between driving time of different road segments and the correlation of driving time in different seasons and different time segments of the same road segment was used to establish the time estimation model with time-space correlation analysis. The statistical method was used to eliminate the error of dynamic model.
