基于动态分段技术的路段交通流量可视化方案探讨

在介绍动态分段基本原理的基础上,以广东省普通国道网为例,将里程桩号作为路线系统的量测M值的校正参考依据,并把年度交调数据中路段交通流量观测值作为线事件引入国道网的路线系统中,实现了路段交通流量与空间矢量地图的匹配,为路网的进一步网络分析及研究决策提供了科学的参考依据。

Research on Visualization of Traffic Volume Based on Dynamic Segmentation Method - Taking the National Highway Network in Guangdong Province as Example

This paper introduces the principles of Dynamic Segmentation, and taking the national highway network in Guangdong Province for example, by using route mileage as M - value of route system, with the traffic observed data collected from the annual traffic survey data being imported to the route system of national highway network as line events, the traffic volume data can match to the vector map, which could provide a basis for the further analysis on the highway network.
