Abstract

The invention discloses an urban road network congestion mode recognition method based on space-time characteristics, electronic equipment and a computer storage medium, relates to the field of intelligent transportation, and aims to complete congestion mode recognition of a congested road section. The method comprises the following steps: acquiring real-time road network congestion alarm data andhistorical road network congestion alarm data; respectively establishing a historical congestion alarm intensity distribution model and a real-time congestion alarm intensity distribution model of each road section through adoption of a kernel density estimation method; comparing the historical congestion alarm intensity distribution model and the real-time congestion alarm intensity distributionmodel of each road section, and determining congestion alarm time period characteristics of each road section; according to the importance level of the downstream intersection of each road section and the spatial form formed by the congested road sections in each direction, forming congestion alarm form features of each road section; and combining the congestion alarm time period characteristicsand the congestion alarm morphological characteristics to form a congestion mode.

本发明公开了一种基于时空特征的城市路网拥堵模式识别方法、电子设备和计算机存储介质，涉及智能交通领域，旨在完成拥堵路段的拥堵模式识别。其中所述方法包含以下步骤：获取实时路网拥堵报警数据和历史路网拥堵报警数据；通过核密度估计方法，分别建立各路段的历史拥堵报警强度分布模型和实时拥堵报警强度分布模型；比对各路段的所述历史拥堵报警强度分布模型和所述实时拥堵报警强度分布模型，确定各路段的拥堵报警时段特征；根据所述各路段下游路口的重要度等级以及各方向拥堵路段构成的空间形态，构成所述各路段的拥堵报警形态特征；组合所述拥堵报警时段特征和所述拥堵报警形态特征，构成拥堵模式。
