The invention belongs to the technical field of traffic, and particularly relates to an intersection congestion rate evaluation method which comprises the following steps: S1, selecting a target intersection, collecting parking area information of the target intersection, dividing different time periods, and calculating or obtaining congestion state evaluation indexes corresponding to the different time periods from a third-party data source; s2, on the basis of the parking area information of the target road intersection, constructing a congestion rate model of the target road intersection in the passing period; s3, based on the current time period, calculating the congestion rate of the target road intersection in the passing period, and based on the congestion state evaluation index, judging the congestion state of the current target road intersection; s4, realizing visual output of a congestion state prediction result by adopting a programming language; according to the method, the predicted congestion state and the congestion rate of the target road intersection can be visually output, so that subsequent vehicles can conveniently master the congestion state of the target road intersection, the most reasonable route can be selected according to the congestion rate when a plurality of road intersections are blocked, and the road passing efficiency is further improved.
本发明属于交通技术领域,具体涉及一种道路口拥挤率评价方法,包括如下步骤:S1:选取目标道路口,采集目标道路口停车域信息,并划分不同时段,计算或从第三方数据源获取不同时段对应的拥挤状态评价指标;S2:基于目标道路口停车域信息,构建通行周期内的目标道路口的拥挤率模型;S3:基于当前时段,计算目标道路口通行周期内的拥挤率,并基于拥挤状态评价指标判别当前目标道路口的拥挤状态;S4:采用程序设计语言实现拥挤状态预测结果的可视化输出;能够通过该方法可视化输出目标道路口的预测的拥挤状态和拥挤率,以便于后续车辆对目标道路口的拥挤状态掌握,以及能够在多个路口堵塞时依据拥挤率选择出最合理路线,进而提高道路通行效率。
