摘要
为有效提高公路区域OD数据拟合效果和资料使用率,在合理简化交通分区间OD变化关系的基础上,将公路区域OD按自然增长OD量、局部路网变化引起的OD调整、区域出现新经济增长点引起的新增OD3种类型,研究其维护更新方法。
To improve the fitting results and information utilization of regional highway OD data,based on the reasonable simplification of the OD relationship,the paper studies the updating methods according to natural growth of the regional OD,OD adjustment due to local road network change and the new OD due to new regional economic growth points.
