The invention relates to an expressway reconstruction and extension separation type interchange left entry guide change ramp and a speed control method, and belongs to the field of intelligent traffic. According to the method, active control strategies such as entrance ramp control, speed guidance and collision early warning are combined with a traffic guide and change organization scheme, it is ensured that the running speed of a vehicle on a ramp at the left-entry confluence area is close to that of a vehicle on a lane on the inner side of a main line, the driving order is guaranteed, the speed discreteness of the confluence area is reduced, and the traffic safety level is improved. The method can be applied to separation type interchange left-entry guide and change points in the reconstruction and extension period of expressways, common roads and urban roads, and is used for refined intelligent management and control of the separation type interchange left-entry guide and change points in the reconstruction and extension period of the expressways.

    本发明涉及一种高速公路改扩建分离式立交左入导改匝道及速度控制方法,属于智能交通领域。该方法通过入口匝道控制、速度引导、碰撞预警等主动控制策略与交通导改组织方案相结合,确保在左入汇入合流区处匝道上车辆行驶速度与主线内侧车道上车辆接近,有利于保障行车秩序、降低合流区速度离散性、提升交通安全水平。本发明可应用于高速公路、普通公路、城市道路的改扩建期分离式立交左入导改点,用于高速公路改扩建期分离式立交左入导改点精细化智能管控。
