摘要
城市快速路建设的速度远不及交通量的增长速度,且目前我国缺乏对其交通流特性及控制技术的系统研究,大量车流从入口匝道无序的汇入主线,严重影响了城市快速路功能的正常发挥。文中以实测数据为基础,利用设计学原理,分析城市快速路入口匝道交通流特性及其对主线交通流的影响,得出在快速路匝道上的车速特性。
The construction of urban expressways is much slower than traffic growth.At present,there is a lack of holistic research on the characteristics of traffic flow and control technology of urban expressway.A great quantity of traffic gets into the main lines out of order from the on-ramp,which has a negative effect on expressway traffic.Based on the measured data,this paper analyzed the on-ramp traffic flow and the impact on traffic flow of the main line,which provides references for establishing a better control method for the on-ramp of urban expressway.
