城市道路用地的预测和控制

在预测和评价城市道路用地时,一般惯用“道路用地面积率”和“人均城市道路用地”两个指标,其在反映城市道路用地能否符合交通要求方面有一定局限性。本文介绍了一种比较简单的城市道路用地预测模型,采用城市规划年限时的城市人口密度、居民出行方式和车速等指标因素,以适合具体城市的交通特点和需求。

Projection and Management of Urban Traffic Land Use

Projection and appraisal for urban traffic land use have adopted the rate of land area for traffic use and area of urban traffic land per capita as two index factors but whether the findings could truthfully show the reqirements of traffic is doubtful as there is imitation in these factors. The article proposes a simple model for projection of urban land use based on analyses of urban population density projected for that planning period and such other factors as the mode of trips of the population and the speed of vehicles.
