摘要

从满足高速公路交通安全联网联控对路网模型的精细化需求角度分析了路网建模的要点，提出了一种适合高速公路路网数据表达、操作的高速公路基础路网数据模型。该模型基于分层拓扑组织路网要素，以里程桩号作为路网建模划分的最小粒度，同时包含车道信息，可根据不同需求组合为抽象路网。模型包含有向路段、有向路段结点、有向子路段、有向子路段结点、车道、车道连接器六个部分，能够细致的描述高速公路路网拓扑结构。选取沈海高速与沪陕高速共用路段区域路网作为试验区域，建立了基于该模型的高速公路路网数据库，并将模型应用于高速公路突发事件处理，实例表明该模型有利于迅速响应高速公路网络的突发事件，满足高速公路交通安全联网联控相关应用对路网模型的需求。

Abstract

In order to satisfy the function demand of expressway traffic safety networked joint control

an expressway road network model is proposed

which is suitable for data presentation and operation. The model is constructed based on hierarchical topology network elements with landmark as a minimum size of the road network model partitions. The lanes are described precisely

and road network modeling units could be combined into abstract network according to different traffic demands. The model is composed by 6 parts including arc

arcnode

segment

segmentnode

lane and laneconnector

which could be used to describe the highway road network topology carefully. This model is tested in the emergency response of expressway by using the common section of Shen Hai expressway and ShanghaiShanxi expressway as a testing section

the result shows the model could satisfy traffic safety management demands effectively.
