Vehicle and road collaborative information-based signalized intersection vehicle speed guidance system and method

The invention provides a vehicle and road collaborative information-based signalized intersection vehicle speed guidance system, which comprises an information communication module, an information acquisition and processing module, a vehicle speed guidance and suggestion module and a vehicle safety early-warning module. The information acquisition and processing module is used for acquiring the information of a vehicle through the acquisition and processing process of the combination of a GPS and an INS. The information acquisition and processing module is also used for acquiring the information of a preceding vehicle and the signal state information of an annunciator via the information communication module. By means of the vehicle speed guidance and suggestion module, after the entrance of the above vehicle into a guidance range, whether the vehicle is within the range of lane-changing-allowable road segments or not is judged based on the vehicle information within the guidance range and the signal state information of the annunciator. Meanwhile, the vehicle speed guidance and suggestion module provides a vehicle speed guidance suggestion and a driving lane suggestion to the vehicle. The vehicle safety early-warning module calculates a safety margin value between two vehicles according to the information of the vehicle and the information of the preceding vehicle, and then judges the collision risk state of the vehicle according to the safety margin value. According to the invention, the real-time position of the vehicle, the real-time speed of the vehicle and the mutual influence among vehicles are fully contemplated. In this way, when the vehicle passes through a signalized intersection, the stop delay of the vehicle is reduced. Therefore, the traffic efficiency of roads is improved and the environmental pollution is reduced.
