Embodiment 1

[0064] The execution subject of the traffic data processing method proposed in the embodiment of the present application is the above-mentioned server, and the above-mentioned server obtains the signal switching event package of the road intersection in the previous time interval, and uses the signal switching event package to generate a periodic event set, and the periodic event The contents of the detector event packets in the collection are extracted to determine the traffic data of road intersections.

[0065] Before the server executes the traffic data processing method, it needs to perform the following steps (1) to (2):

[0066] (1) System initialization, create database and tables, create message queues for signal machines and detectors for road intersections, based on the signal evaluation index algorithm of aggregated traffic data, the message queue corresponds to each aggregated traffic data , using the aggregated traffic data to evaluate the signal indicators, incl...

Embodiment 2

[0122] This embodiment proposes a traffic data processing device for executing the above traffic data processing method.

[0123] see Figure 4 As shown, a traffic data processing device includes:

[0124] The acquiring module 400 is configured to acquire signal switching event packets and detector event packets at road intersections in the preceding time interval according to a preset time interval;

[0125] The first generating module 402 is configured to generate the signal cycle sequence of the above-mentioned road intersection by using the switching time stamp contained in the above-mentioned signal switching event package;

[0126] The second generating module 404 is configured to aggregate the above-mentioned detector event packets according to the above-mentioned signal cycle sequence to generate a set of periodic events;

[0127] The determination module 406 is configured to extract the content of the detector event package in the periodic event set, and determine t...

Abstract

The invention provides a traffic data processing method and apparatus. The method includes: acquiring a signal switching event packet and a detector event packet of a road intersection in a previous time interval according to a preset time interval; generating a signal period sequence of the road intersection by utilizing a switching timestamp included in the signal switching event packet; aggregating the detector event packet according to the signal period sequence to generate a periodic event set; and extracting the content of the detector event packet in the periodic event set to determinetraffic data of the road intersection. Through the traffic data processing method and apparatus, the traffic data that can accurately reflect the real situation of roads can be continuously obtained.

Description

technical field [0001] The present application relates to the technical field of traffic data processing, and in particular, to a traffic data processing method and device. Background technique [0002] At present, with the acceleration of urban construction across the country, the number of roads and vehicles has become larger and larger. Including old renovation projects, urban traffic pressure is huge, and road congestion often occurs. In order to improve the road congestion situation, the road condition of the road can be evaluated, and the signal phase of the road can be adjusted according to the evaluation result to improve the road congestion situation. [0003] When evaluating the road condition, the road condition data will be collected through manual investigation first, and then the road condition data collected by manual investigation will be input into the road condition simulation software, and the current intersection operation status will be evaluated through...
