Abstract

The invention relates to a full-dose full-sample real-time traffic data-based multi-parameter fusion method and system. The method comprises the steps of extracting moving vehicles on the basis of animage sequence of a monitor video so as to obtain vehicle trajectory data, and carrying out mathematical statistics on the vehicle trajectory data of each vehicle type to obtain traffic flow data; respectively extracting the traffic flow data on the basis of radar microwave data and earth coil data; and fusing any parameter, in the traffic flow data, respectively obtained by the vehicle trajectorydata, the radar microwave data and the earth coil data according to each set weight. For the characteristics such as diversity and complexity of multi-source heterogeneous information in the form, the data of three sources such as coil data, radar microwave data and road monitor video is processed, and a data mining technology and a data fusion technology are combined to construct a multi-mode information fusion model. On the basis of the effective fusion of the full-dose full-sample real-time traffic data, more useful and comprehensive traffic information can be obtained, so that the urban traffic problems can be better solved.

Description

technical field [0001] The invention relates to the technical field of road traffic simulation, in particular to a multi-parameter fusion method and system based on full-scale and full-sample real-time traffic data. Background technique [0002] With the rapid growth of car ownership, traffic congestion not only affects the lives of residents, but also becomes an "urban disease" that hinders the further development of the national economy. The root cause of road traffic congestion is the imbalance between traffic demand and traffic supply in time and space. [0003] At present, most of the traditional road traffic data applications are only for single data source data, and cannot obtain comprehensive and accurate road traffic status and traffic demand, so they cannot effectively solve the problem of road traffic congestion. With the continuous improvement of urban roads and supporting facilities, road monitoring facilities such as radar microwaves, road monitoring and geoma...
