摘要
分析了公路网络栅格建模对提高交通体系和城镇体系研究精度的重要意义,提出了公路网络栅格模型的基本框架。以湖北省公路网为例,系统介绍了公路网线形及其属性的模拟技术、公路行车速度的模拟技术,以及基于栅格公路网的最短行车路线和行车时间的模拟技术。分析了该模型的应用前景,并以城镇辐射强度为例,验证了模型的效力。
Firstly, this paper analyzes the significance of road network model based on grid, and puts forward the structure of the model. Then, taking road-network in Hubei as an example, the paper introduces the simulation technologies of road shape and attributes, driving speed, and shortest driving path and driving time. Finally, the prospect of the model is analyzed, and the efficiency of the model is tested through the simulation of city affective intensity.
