The invention discloses a city-level overall traffic signal control method and a city-level overall traffic signal control device. The method comprises the following steps of classifying the urban districts according to an urban area district rule, an urban line district rule and a traffic flow change rule in a preset time period which are determined according to multi-source urban traffic data toanalyze the overall urban traffic in the spatial dimension; obtaining a city district division set; carrying out time dimension adjustment on the urban district division set; obtaining a dynamic citydistrict division set; extracting the traffic features of each district in the dynamic urban district division set; determining a control strategy corresponding to the traffic characteristics from acontrol strategy library, according to the control strategy, carrying out traffic signal control on the corresponding districts, and optimizing the signal control scheme of the districts by taking thedistricts as basic units, so that urban district division is more accurate, the urban districts do not need to be divided manually, and the overall traffic signal control capability of the city is improved.
本发明公开了一种城市级整体的交通信号控制的方法及装置,包括:根据多源城市交通数据确定出的城市面积片区规律、城市线路片区规律和预设时间段的交通流量变化规律,对城市片区进行分类,以对城市整体交通在空间维度上进行分析,得到城市片区划分集合,再对城市片区划分集合进行时间维度上的调整,得到动态的城市片区划分集合,提取动态的城市片区划分集合中每个片区的交通特征,从控制策略库中确定出交通特征对应的控制策略,根据控制策略,对相应的片区进行交通信号控制,以片区为基本单位,对片区的信号控制方案进行优化,以实现城市片区划分更加准确,不再需要根据人工对城市片区进行划分,提升城市整体的交通信号控制能力。
