The invention discloses an urban road traffic event influence evaluation method and a system and a storage medium, and the method comprises the following steps: S01, dividing road network road data into standard small segments, and obtaining a corresponding road condition congestion state level; S02, setting a congestion threshold according to the corresponding road condition level, and generatingtwo types of congestion events of a road section congestion source and an intersection congestion source; S03, based on the two types of congestion events, calculating traffic congestion event related indexes: a traffic damping coefficient, a maximum duration and a maximum diffusion length; and S04, calculating traffic event influence indexes. According to the invention, congestion events occurring on urban roads can be displayed in real time, early warning prompts can be generated, a related ranking list can be made, data reference can be provided for dispatch of traffic polices to patrol polices, and the event data can be used for more detailed design of an urban traffic event processing system.

    本发明的一种城市道路交通事件影响评价方法、系统及存储介质,包括以下步骤:S01、划分路网道路数据为标准小段距,并获取对应路况拥堵状态等级;S02、根据对应路况等级,设定拥堵阈值,产生路段拥堵源头和路口拥堵源头两类拥堵事件;S03、基于两类拥堵事件,计算交通拥堵事件相关指标:交通阻尼系数、最大持续时间、最大扩散长度;S04、计算交通事件影响力指标。本发明可实时展示城市道路发生的拥堵事件,产生预警提醒,并做相关排行榜,可给交警的派出巡警提供数据参考,可将此事件数据用于更细化的城市交通事件处理系统的设计。
