Embodiment Construction

[0040] The present invention will be further described below in conjunction with the drawings and embodiments.

[0041] The invention is a road traffic operation index detection method based on large-scale floating car data. This method can be completed by two implementation subjects, one is the main control system, which is responsible for loading static basic data, task decomposition and scheduling, and comprehensive judgment of the final result. The other is the calculation system, which is responsible for preprocessing the floating car data, map matching and calculating the average speed of the road section.

[0042] Such as figure 2 As shown, the working process of the present invention is as follows:

[0043] Step 1. System initialization

[0044] The main control system starts, initializes the processing system, loads map data and configuration files, etc., initializes the computing system, and establishes status monitoring and management lists.

[0045] Step 2: Task decompos...

Abstract

The invention discloses a road traffic operation index detection method based on large-scale floating car data. According to the method, on the basis of a traffic network and static basic data such asconfiguration files and the like, a road section where each piece of floating car data is positioned is calculated by utilizing GPS positioning data, a driving direction angle, time and car number information of a floating car, so as to solve an average speed of the road section and finally, give out a traffic operation index of the road section according to a judgment standard. In the method, the key steps comprising floating car data preprocessing, floating car data and map matching, road section speed calculation, final integration of the traffic operation indexes of all the road sectionsand the like are all concurrently carried out, and the concurrent process is controlled by a dynamic task allocation algorithm. According to the invention, road traffic operation condition informationwhich is more rapid, accurate and easy to understand is provided for a user, so that the user can stagger a severe crowded road section and trip efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the field of intelligent traffic road traffic operation index detection, in particular to a road traffic operation index detection method based on large-scale floating car data. Background technique [0002] Traffic congestion has gradually become the primary problem for large and medium-sized cities in my country. How to timely reflect the road conditions on these roads and provide accurate guidance for travelers has become an urgent problem in the field of intelligent transportation. Traditional road operation information collection methods are no longer able to adapt to the rapidly increasing number of roads and vehicle ownership. Floating car technology, as a brand-new urban road condition information acquisition, road construction and travel planning method, has gradually become a research hotspot. [0003] Due to the large scale of floating car data and the existence of many invalid data, it brings many difficulties to the anal...
