Embodiment Construction

[0037] A system for recommending congestion control strategies in urban road areas includes: a congestion group identification module, a control strategy recommendation module, and a congestion group control urgency identification module.

[0038]1) Congestion group identification module, according to the structural characteristics and traffic flow characteristics of the road network, identify the time-space correlation between intersections and intersections. When the congestion group conditions are met, the intersection and the road section between the intersections are time-space association road sections, and time-space association road sections and the intersections at both ends form a congestion group, and the spatio-temporal correlation refers to the mutual influence of traffic flow characteristics in time and space.

[0039] Wherein, the structural features of the road network include but are not limited to one or a combination of the length of the road section, the lon...

Abstract

The invention provides an urban road region congestion regulation and control strategy recommendation system and method. The space-time correlation between intersections is recognized to form a congestion group; priority ranking is carried out on the intersections in the congestion group, the intersection with the highest priority level is used as a key intersection, upstream and downstream intersections of space-time correlation type road sections of the key intersection are searched for, and an intersection regulation and control sequence recommendation is provided; a regulation and controltarget of the key intersection is decomposed into the intersections of the congestion group, and an intersection regulation and control target recommendation is provided; and according to features ofthe congestion group, corresponding regulation and control measure recommendations are provided. Rapid and real-time pushing of a regulation and control strategy is realized, and the efficiency of formulating the regulation and control strategy by timing personnel is improved.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a system and method for recommending strategies for controlling congestion in urban road areas. Background technique [0002] Urban road traffic arteries support the entire urban road network, and intersections, as joints connecting arteries, directly affect the operation of the road network. If the traffic capacity of a certain intersection is insufficient and congestion occurs, resulting in the accumulation of traffic flow, the congestion will spread to the surroundings, causing more intersections to be congested. [0003] At this time, regional congestion conditions can be observed on the map, and a series of congested intersections can be identified in time and space. In the time dimension, the intersections in the congested area are at approximate time nodes; in the spatial dimension, the intersections in the congested area are connected to each other and distributed in a sma...
