摘要
为缓解上海市高架路非高峰时段的拥堵,对上海市高架路非高峰时段拥堵状况与成因进行研究。首先,基于百度地图实时数据识别拥堵常发路段及其拥堵特征;其次,基于上海高架路小时流量数据、土地利用数据以及建筑物普查数据,采用线性回归等方法,通过分析上海南北高架路东侧出入口匝道小时流量与其影响范围内土地利用的关系,发现匝道车流量与其影响范围内商业用地、物流用地、办公用地等建筑面积之间存在相关性,高架路拥堵的产生与背景交通量和匝道车流量之间密切相关;最后,针对拥堵原因提出缓解高架路拥堵的相关建议。
In order to alleviate the off-peak congestion of elevated roads in Shanghai,this paper studies the status and causes of off-peak congestion on elevated roads in Shanghai.Firstly,identifying the frequent congested sections and characteristics based on real-time data of Baidu map.Secondly,based on the hourly flow data,land-use data and building census data,the relationship of the hourly flow of ramp on the east side of the South North elevated road in Shanghai and its surrounding landuse is studied by using linear regression method.It is found that there is a correlation between the ramp-traffic flow and the building areas of commercial land,logistics land,office land and other land within the surrounding scope,and the congestion on elevated roads is closely related to the background traffic volume and ramp traffic flow.Finally,putting forward some relevant suggestions to alleviate the congestion on elevated roads.
