Method for determining traffic incident impact areas and durations on basis of coil detection

Abstract

The invention relates to a method for determining traffic incident impact areas and durations on the basis of coil detection. The method includes enabling coils to acquire traffic flow and spot average speed data at preset intervals when traffic incidents occur, and updating queuing lengths of road sections; updating queuing lengths of various access roads when the queuing lengths of the road sections are larger than the distances from traffic incident occurrence spots to intersections; updating dissipation lengths of the road sections and the queuing lengths of the various access roads when the traffic incidents are completed; updating dissipation lengths and the queuing lengths of the various access roads when the dissipation lengths of the road sections are larger than the distances from the traffic incident occurrence spots to the intersections; determining that the traffic incidents are completely finished when the dissipation lengths of the various access roads are larger than the corresponding queuing lengths, and determining the incident impact areas and the durations. Compared with the prior art, the method has the advantages that development of the traffic incidents is observed in real time by the aid of the coils, accordingly, the traffic incident impact areas and the impact durations can be accurately estimated, and a decision basis can be provided for traffic control and management.

Description

technical field [0001] The invention relates to the field of traffic control and management, in particular to a method for determining the influence range and duration of a traffic event based on coil detection. Background technique [0002] With the rapid development of urban economy and social activities, and the acceleration of urbanization, the challenges faced by my country's urban transportation are also deepening: the shortage of land resources, the increase of energy pressure, and the diversification of social needs. Focusing on scientific and refined requirements, the decision-making level of urban road traffic planning and management needs to be improved urgently. On the other hand, with the development of intelligent transportation technology and the establishment of traffic information systems, urban planning and management departments have provided abundant traffic data resources. How to make full use of various data to carry out multi-dimensional analysis and p...

Problems solved by technology

[0007] Generally speaking, the application of my country's urban signal traffic control system is relatively mature, but there is no reasonable application of the data collected by the control system. How to combine the existing traffic data with traffic analysis methods to provide a basis for traffic control and management remains to be done. Empirical Research
