Smart city traffic management method for adjustment based on traffic flow

Abstract

The invention relates to the technical field of traffic planning, in particular to a smart city traffic management method for adjustment based on traffic flow, and the method comprises the steps: analyzing the saturation of a road through the collection of the real-time traffic flow of the road, and carrying out the adjustment according to a set road optimization threshold value; and when the road saturation exceeds the road optimization threshold, performing signal timing on signal lamps at the road intersection. The signal timing of the signal lamp is adjusted according to the traffic condition on the road, the traveling of the traffic flow on the road is controlled, the traffic control at the intersection can be dynamically changed according to the actual condition, the traffic jam condition is relieved, the operation efficiency of the road traffic is improved, the workload of the traffic police is reduced, and the traffic operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a smart city traffic management method based on traffic flow adjustment. Background technique [0002] Road traffic is an important part of the city's comprehensive traffic system, and the improvement of its operating efficiency can bring huge economic and social benefits to the city. Most of the current urban traffic is controlled by signal lights, and the traffic flow is separated into different time periods for passage, so as to avoid the occurrence of traffic conflicts. However, the existing signal light control is mostly based on timing control. The traffic lights at road intersections are controlled and operated according to a preset timing scheme, which mainly includes single-stage timing control with only one timing scheme a day, and A multi-stage timing control with several timing schemes is adopted for the traffic flow in different time periods in a day. This...

Problems solved by technology

This kind of fixed-period control method is often only applicable to the environment with stable traffic flow, but the traffic system is an uncertain system, and the traffic flow on the road is changing all the time, so the timing control is difficult to reflect the real-time traffic flow well. conditions, which can easily cause traffic jams and reduce the operating efficiency of road traffic

[0003] Aiming at the traffic jam phenomenon, the existing processing methods mostly use the traffic police to conduct on-site command and control the flow of traffic to alleviate the traffic jam situation, but this greatly increases the workload of the traffic police
