The invention discloses a vehicle crowdsourcing obtaining method and system for road speed limit information and belongs to the technical field of intelligent traffic. The method comprises steps of obtaining the driving information, including vehicle position information, driving direction information and vehicle speed information, of all vehicles driving in a specified direction on a specified road section at a specified moment; screening front empty vehicles from all the vehicles according to a preset screening strategy; processing the speed information of all the front empty vehicles to obtain road speed limit information; the screening strategy comprising judging whether other vehicles exist in a specified range in front of the vehicle or not according to the vehicle position information, and if not, judging that the vehicle is a front empty vehicle. According to the method, all the vehicles at the specified moment, the specified road section and the specified direction are screened to determine the front empty vehicle running at the maximum possible driving speed, the speed limiting information is obtained based on the maximum possible driving speed of all the front empty vehicles, the speed limiting information is used for guiding the vehicle to run, and the intelligent degree of vehicle management is improved.
本申请公开了一种道路限速信息的车辆众包获取方法及系统,属于智能交通技术领域,包括获取指定时刻的指定路段上以指定方向行驶的所有车辆的驾驶信息,包括车辆位置信息、行驶方向信息、以及车速信息。根据预设的筛选策略从所有车辆中筛选出前空车辆。根据所有前空车辆的车速信息处理得到道路限速信息。筛选策略包括根据车辆位置信息判断车辆前方指定范围内是否有其他车辆,若否,判断车辆为前空车辆。本申请能够通过对指定时刻、指定路段、以及指定方向的所有车辆进行筛选确定以最大可能驾驶速度行驶的前空车辆,基于所有前空车辆的最大可能驾驶速度得到限速信息,利用该限速信息指导车辆行驶,提高车辆管理的智能化程度。
