基于空间自相关分析的旧路改造交通预测合理范围研究

旧路改造设计是道路设计的重要组成部分,也是优化城市路网结构、缓解交通拥堵的重要手段。从城市规划和城市发展的角度,研究了在旧路改造设计过程中,交通预测分析的难点,利用面状空间数据的自相关特性,结合传统交通预测模式的特点,提出了在城市道路改造设计中,合理确定交通预测分析范围的方法,并结合实际工程案例,验证了提出模型的实际可操作性。

Study on Reasonable Range of Traffic Forecast in Reconstruction of Old Road Based on Spatial Autocorrelation Analysis

The reconstruction design of old road is an important composed part in the road design,and is also the important means to optimize the structure of urban road network and to relieve the traffic jam.From the angle of urban planning and urban development,the article studies the difficulties of the traffic forecast analysis in the course of reconstruction design of old road.Utilizing the autocorrelation characteristic of planar spatial data and combining with the characteristic of traditional traffic forecast mode,the article puts forward the method to reasonably define the analysis range of traffic forecast in the reconstruction design of old road,and validates the practical maneuverability of the proposed model by the engineering cases.
