Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0034] Such as figure 1 As shown, the embodiment of the present invention provides a method for evaluating the traffic operation state of expressways based on multi-source data fusion, including the following steps:

[0035] Step 1. Obtain the operating parameters of inter-section traffic based on multi-source data;

[0036] Step 2, fusing the inter-section traffic operation parameters based on multi-source data to obtain fused inter-section traffic operation parameters;

[0037] Step 3, using the interval traffic operation state index system and the integrated interval traffic operation paramet...

Abstract

The invention discloses a method for evaluating traffic operational conditions of a highway based on multisource data fusion and relates to the technical field of evaluation of the traffic operational conditions. The traffic operational conditions of the highway based on multisource data fusion are evaluated in combination with a large amount of GPS (global positioning system) data acquired and accumulated by a floating car acquisition system and a large amount of toll data acquired and accumulated by a highway toll system by utilizing data of fixed car detectors, and an obtained evaluation result of the traffic operational condition of the highway is more accurate and wider in coverage range, so that a defect of insufficient arrangement of car detectors can be made up for, road network monitoring range and system can be performed, traffic jams on roads can be accurately discovered in time, and the safety and efficiency of road traffic can be guaranteed; moreover, the toll data and floating car data are all based on existing toll system and floating car GPS management system, and the additional data acquisition cost is zero, so that the method provided by the embodiment of the invention is good in economy and promotion prospect.

Description

technical field [0001] The invention relates to the technical field of traffic operation state evaluation, in particular to an evaluation method of expressway traffic operation state based on multi-source data fusion. Background technique [0002] The assessment of traffic operation status has a significant impact on the safety and efficiency of road traffic. Monitoring and predicting the traffic operation state, timely and accurately discovering the traffic congestion on the road has always been the focus and difficulty of research in the field of traffic operation state evaluation. Since the 1960s, the evaluation of expressway traffic operation state It has become one of the hotspots in the field of dynamic traffic management research, and a lot of results have emerged. [0003] At present, the research on the evaluation of traffic operation status mostly relies on the data of fixed vehicle detectors. It is the basis for monitoring and predicting traffic operation status...
