The invention relates to the technical field of road traffic evaluation, and particularly discloses an urban road traffic congestion spatial-temporal distribution comprehensive index evaluation method, which comprises the following steps: calculating the average speed of a road section according to satellite navigation data information obtained at unit time intervals; calculating the congestion mileage of different road types in the road network in unit time, and obtaining the congestion mileage of the whole road network in unit time; calculating road network morning and evening congestion peak periods according to the whole road network congestion mileage in unit time; calculating a four-dimensional road network traffic congestion space-time distribution evaluation index according to the road network morning and evening congestion peak period and the road type; calculating a normal distribution centesimal system score of the four-dimensional congestion space-time distribution evaluation index of each city; and according to the normal distribution centesimal system score, calculating a road traffic congestion time-space distribution comprehensive index of the city. The urban road traffic jam spatial-temporal distribution comprehensive index evaluation method provided by the invention can realize traffic jam quantitative evaluation.

    本发明涉及道路交通测评技术领域,具体公开了一种城市道路交通拥堵时空分布综合指数测评方法,其中,包括:根据每间隔单位时间获取到的卫星导航数据信息计算路段平均车速;计算单位时间内的路网中不同道路类型的拥堵里程,并获取单位时间内的全路网拥堵里程;根据单位时间内的全路网拥堵里程计算路网早晚拥堵高峰时段;根据路网早晚拥堵高峰时段及道路类型计算四维路网交通拥堵时空分布评估指标;计算每个城市的四维拥堵时空分布评估指标的正态分布百分制得分;根据正态分布百分制得分计算该城市的道路交通拥堵时空分布综合指数。本发明提供的城市道路交通拥堵时空分布综合指数测评方法能够实现交通拥堵量化测评。
