基于断面流量分布的粤西公路通道适应性分析

Adaptability Analysis of Western Guangdong Road Channel based on Section Runoff Distribution

粤西是广东省经济发展新的增长极,交通运输是区域经济发展的基础与先导,合理规划联系珠三角与粤西的公路通道资源意义深远。但粤西通道研究范围广,传统"四阶段"法所需资料获取时间长、成本高,全路网交通复杂,难以准确预测。研究结合区域经济社会发展规划,以断面流量分析为抓手,在既有路网适应性分析的基础上,提出粤西路网优化的建议。

The western area has become a new growth pole of economic development in Guangdong, and trans-portation is the basis and guide for regional economic development. So reasonable planning of road channel re-sources between Pearl River Delta and western Guangdong is of far-reaching significance. But as research scope for the channel is wide, the traditional “four stage” method needs long time and high cost, and the whole road network is complicated, it is difficult to accurately predict. The research, being combined with the regional eco-nomic and social development planning, being based on section runoff analysis, and on the analysis of existing road network adaptability, the optimization suggestion of Western Guangdong road network has been put forward.
