The invention discloses an expressway ramp signal control method, device and system. The method comprises the following steps: determining an express way entrance serving as a control object in an express way; acquiring driving track information of a vehicle passing through the expressway entrance within a preset time period; calculating traffic flow information at the entrance of the expressway according to the driving track information; and selecting a preset signal control mode for the expressway entrance according to the traffic flow information. The invention provides an expressway entrance flow control strategy based on driving track information. The vehicle afflux quantity of each expressway entrance ramp can be controlled in a targeted manner. Therefore, the vehicle density of theconfluence area of the ramp auxiliary road and the main road does not exceed the critical density, and vehicle afflux quantity of each expressway entrance ramp can be controlled in targeted manner. Itis ensured that the downstream road section is always in an unsaturated state, the traffic flow afflux pressure is relieved, and the purposes of improving the urban traffic network operation efficiency and relieving urban traffic congestion are achieved.

    本发明公开一种快速路匝道信号控制方法、装置和系统。其中的方法包括:确定快速路中作为控制对象的快速路入口;获取在预定时间段内途经所述快速路入口的车辆的行驶轨迹信息;根据所述行驶轨迹信息计算所述快速路入口处的车流信息;以及根据所述车流信息针对所述快速路入口选择预设的信号控制模式。本发明提供了一种基于行驶轨迹信息的快速路入口流量控制策略,能够有针对性地控制各个快速路入口匝道的车辆汇入量,使匝道辅路和主路的合流区的车辆密度不超过临界密度,确保下游路段始终处于非饱和状态,缓解车流量的汇入压力,从而达到提高城市交通路网运行效率、缓解城市交通拥堵的目的。
