Ramp control method, device and system

The embodiment of the invention provides a ramp control method, device and system. The method comprises the steps that first data and second data are obtained, the first data are vehicle speed data, and the second data are lane occupancy; determining a traffic mode according to the first data and the second data; and determining a control strategy according to the optimization control parameter corresponding to the traffic mode and the second data. According to the ramp control method, device and system provided by the invention, the traffic mode is determined through the vehicle speed data and the lane occupancy, and the adaptive control strategy is determined according to the optimal control parameter corresponding to the traffic mode. Therefore, a more accurate traffic mode can be obtained, and a more effective control strategy can be obtained, so that the main line of the expressway can be smooth. 本申请实施例提供了一种匝道控制的方法、装置和系统。该方法包括：获取第一数据和第二数据，其中，第一数据为车辆速度数据，第二数据为车道占有率；根据第一数据和第二数据确定交通模式；根据与交通模式相对应的优化控制参数与第二数据
