高密度开发区道路网等级配置研究

Study on Level Allocation of Road Network in High-density Development Area

以道路网周转量最大和道路建设资金最小为出发点,通过对交通供需平衡、交叉口信控、公交站距、步行距离的综合分析,建立高密度片区道路网等级配置模型,并结合上海市张江科技城核心区道路网具体实例,推算道路等级的最优配置。其结果表明:张江科技城核心区最优的等级配置为1∶2.1∶3.6∶9.8,片区对低等级道路需求较为旺盛。

Taking the maximum turnover volume of road network and the minimum construction cost of road as the starting point,the article comprehensively analyzes the traffic supply and demand balance,the signal control at intersection,the distance among bus stops and the walking distance to establish the level allocation model of road network in high- density area According to the detail case of road network in the core area of Shanghai Zhangjiang Science and Technology City,the optimized allocation of road levels is calculated.The result shows that the optimized level allocation in the core area of Shanghai Zhangjiang Science and Technology City is 1:2.1 and 3.6:9.8.The demand of low- level road is relatively strong in the area.
