摘要
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 travel time estimation model based on the dynamic fluid equation can not reflect the actual travel time well, which needs to make certain improvement. After the construction of the hydrodynamics model on traffic flow, this paper introduces the correlative analysis on travel time relevance among different road sections and among different seasons, different section times in the identical road section in the highway road network. The traffic time estimation model with temporal and spatial correlative analysis is set up, and the statistics methodology is used to eliminate the error of the dynamics model.
