The invention relates to a public service traffic management system based on the Internet of Things. The public service traffic management system comprises a public service platform, an information monitoring unit, a road condition analysis unit and a traffic regulation and control unit, the road condition analysis unit is used for analyzing the unobstructed degree or the congestion degree of traffic operation according to the vehicle operation condition identified by the information monitoring unit, and analyzing the change condition along with the time and the position; and the traffic regulation and control unit is used for taking corresponding measures according to a result obtained by the road condition analysis unit. According to the invention, the traffic regulation and control strategy is adjusted according to the congestion index, and the operation flexibility of the system is improved on the whole; a single congestion index is introduced to pre-judge the vehicles about to enter at the evaluated intersection, so that the predictability of the road traffic operation condition is improved; related congestion indexes are introduced, so that the coordination degree of the to-be-evaluated intersection and the nearby intersections is improved; and the evaluation frequency of the congestion index is adjusted according to the running condition of the road surface, so that the adaptability to the traffic running conditions in different time periods is enhanced.

    本申请涉及一种基于物联网的公共服务交通管理系统,包括:公共服务平台、信息监测单元、路况分析单元、交通调控单元;所述路况分析单元用于根据信息监测单元识别车辆运行状况分析交通运行的通畅程度或拥堵程度,并随时间和位置的变化情况;所述交通调控单元用于根据路况分析单元得出的结果采取相应措施。本申请根据拥堵指数调整交通调控的策略,整体提高了系统运行的灵活程度;引入单一拥堵指数,对评价路口的即将汇入车辆进行预判,提高了对路面交通运行状况的预见性;引入相关拥堵指数,提高了待评价路口和附近各路口协调配合程度;根据路面的运行状况调整对拥堵指数的评价频率,增强了对不同时段交通运行状况的适应性。
