Embodiment Construction

[0028] Such as figure 1 As shown, the present invention firstly designs the traffic congestion state evaluation method based on interval traffic parameters and location traffic parameters, processes the interval and location traffic parameters collected in real time, evaluates the real-time congestion state of traffic flow, and passes regular traffic The online estimation method of congestion duration and diffusion range obtains the estimated duration and diffusion range of frequent traffic congestion, which provides a basis for traffic managers to make reasonable decisions.

[0029] Among them, the online identification method of road traffic congestion based on interval traffic parameters, in the theory of traffic flow, the relationship between the flow and speed of continuous traffic flow is a parabola. When the traffic demand is low, the traffic flow on the road is small, and all vehicles can run at a higher speed, and the headway is larger at this time; as the traffic dem...

Abstract

The invention discloses an on-line recognition method of the road traffic congestion state, relating to a traffic information processing method which comprises the following steps of: acquiring interval traffic parameter data and location traffic parameter data; transmitting the data back to an information processor; analyzing the traffic parameter data through the information processor by adopting the on-line recognition method; and determining the congestion conditions, the congestion time and the spatial diffusion range of each road section by using the acquired interval traffic parameter and the location traffic parameter for serving other subsystems of a traffic management and control system. The invention provides real-time and reliable traffic state information for the traffic management and control system of the road as well as an important information base for the science of the traffic management decision and the traffic travel decision.

Description

technical field [0001] The invention relates to a traffic information processing method in the field of intelligent traffic systems, in particular to an online identification method for road traffic congestion. Background technique [0002] With the rapid development of the national economy and the acceleration of urbanization, the number of motor vehicles and road traffic in my country has increased rapidly, and the problem of traffic congestion has become increasingly serious. At present, the main road network structure of most cities has basically taken shape, and it is impossible to carry out substantial transformation. In this case, it has become a consensus to adopt advanced traffic management system to improve the efficiency of road use. As an important part of the traffic management system, it is particularly important to conduct in-depth research on the online identification method of road traffic congestion status. [0003] At present, the existing achievements a...
