The invention relates to the technical field of traffic, and discloses a regional traffic congestion index calculation method and device. The method comprises the following steps: for each starting and ending point OD in a traffic road network area, calculating the intermediate property of a road section i; acquiring the real-time traffic flow of the road section i acquired by a road sensor, and preprocessing the real-time traffic flow of the road section i to obtain the preprocessed real-time traffic flow of the road section i; calculating the saturation of the road section i according to the preprocessed real-time traffic flow of the road section i and the traffic capacity of the road section i, and taking the calculated saturation of the road section i as a real-time congestion index of the road section i; and calculating a regional congestion index according to the intermediate properties of all the road sections and the real-time congestion indexes of all the road sections. Therefore, the regional congestion index can be accurately calculated, and the regional congestion index can be better used as a basis for urban traffic refined management and control.
本发明涉及交通技术领域,公开了一种区域交通拥堵指数计算方法和装置。其中,该方法包括:针对交通路网区域中的每个起止点OD,计算路段i的中间性;获取道路传感器采集的路段i的实时车流量,并对路段i的实时车流量进行预处理,得到预处理后的路段i的实时车流量;根据预处理后的路段i的实时车流量与路段i的通行能力计算路段i的饱和度,并将所计算的路段i的饱和度作为路段i的实时拥堵指数;根据所有路段的中间性和所有路段的实时拥堵指数计算区域拥堵指数。由此,可以准确地计算区域拥堵指数,从而更好地作为城市交通精细化管控的基础。
