The invention discloses an entrance and exit ramp traffic organization method and system based on traffic flow characteristics, and relates to the field of traffic organization, and the method comprises the steps: collecting traffic flow data and passing time data of all entrance and exit ramps in a target traffic area; calculating a congestion index of each entrance/exit ramp according to the traffic flow data and the passing time data; calculating a pressure index of each entrance/exit ramp according to the congestion index, the traffic capacity of the entrance/exit ramp and the total length of the ramp; dividing each entrance/exit ramp into a conventional ramp and a control ramp according to the pressure index; compiling a ramp design scheme for each conventional ramp and each control ramp, wherein the ramp design scheme comprises a conventional lane line layout and a gradient virtual and solid line layout; and integrating each ramp design scheme into a regional overall design scheme. By implementing the method, the road passing efficiency of the entrance and exit ramps can be improved.
一种基于交通流特性的出入口匝道交通组织方法及系统,涉及交通组织领域,该方法包括:采集目标交通区域内所有出入口匝道的车流量数据和通行时间数据;根据该车流量数据和该通行时间数据计算每个该出入口匝道的拥堵指数;根据该拥堵指数、该出入口匝道的通行能力和匝道总长度计算每个该出入口匝道的压力指数;根据该压力指数将每个该出入口匝道划分为常规匝道和控制匝道;为每个该常规匝道和该控制匝道编制匝道设计方案,该匝道设计方案内包含常规车道线布局和渐变式虚实线布局;将每个该匝道设计方案整合为区域总体设计方案。实施该方法,可以提高出入口匝道的道路通行效率。
