The invention provides an expressway path guidance method and system under an event condition, and relates to the technical field of traffic, the traffic flow of each road section of an expressway road network in the current time period is acquired, and the road section impedance under the current event road section path condition is calculated; the road section impedance of the whole road network is updated, a new impedance road network is established, and whether the traffic capacity of the event road section can meet the traffic flow of the current time period or not under the event level is judged; if not, traffic flow distribution is carried out, and paths with short detour time and within a specified detour distance range are selected in sequence according to a target function with the minimum path repetition degree; and calculating the total traffic capacity of the selected bypass path, judging whether the road network flow meets conditions and whether the traffic capacity of the event road section meets the bypass path, and if not, continuing to calculate the path until the flow of the induction path is met, namely, the flow induction is successful. And the traffic state problem under the event condition is improved.
本公开提供了一种事件条件下高速公路路径诱导方法及系统,涉及交通技术领域,获取当前时段高速公路路网各个路段中的交通流量,计算出当前发生事件路段路径条件下的路段阻抗;更新整个路网的路段阻抗,建立新的阻抗路网网络,判断在该事件等级下,事件路段的通行能力能否满足当前时段的交通流量;若不能满足,则进行交通流量分配,按照路径重复度最小为目标函数,依次选择绕行时间短、在规定绕行距离范围内的路径;计算已经选择的绕行路径的总通行能力,判断路网流量是否满足条件,事件路段的通行能力是否满足绕行路径,如果不满足,则继续进行路径的计算,直到满足诱导路径流量为止,即诱导流量成功。改善事件条件下的交通状态问题。
