specific Embodiment approach

[0325] From April to June 2006, in the "Shanghai long-term large-area congestion index research" project entrusted by Shanghai Public Security Bureau Traffic Patrol Corps, we based on nearly 5,000 floating vehicles from Shanghai Johnson & Johnson, Haibo and other companies Using this analysis method, a comprehensive analysis of the travel speed of the main and secondary arterial roads in the central city of Shanghai and the degree of congestion in the central city was carried out, and the analysis results were recognized by the traffic police of the entrusting party.

[0326] In the "Transportation Annual Report" project of the Shanghai Municipal Construction and Transportation Commission, this method was used to analyze the speed of road trips.

[0327] This method was applied in the road speed sub-item survey and taxi sub-item survey of the "Third Comprehensive Traffic Survey in Shanghai" to investigate and verify the road travel speed, analyze and verify taxi travel indicato...

Abstract

A method for analyzing traffic on road based on taxi cab data includes utilizing buffer region technique, correlation verification technique, trend included angle technique, active and passive car stopping discrimination technique and data drift-filter technique to carry out car speed analysis, out-driving start-stop point OD analysis and car out-driving index analysis; then making integrated analysis of parameter settings and combining with concrete data reported from taxi cabs to count up out-driving index of taxi cab.

Description

technical field [0001] The invention relates to a traffic analysis method based on floating car data, in particular to a traffic analysis method mainly used for analyzing urban road conditions, counting taxi travel indicators, and calculating taxi travel start-destination point matrix. Background technique [0002] There have been many researches on the use of mobile vehicles for traffic analysis in the world. The main research field is the analysis of road speed and origination-destination (OD) using floating car data (Flating Car Date, referred to as FCD). There are mainly the University of Tokyo, the German Aerospace Center, and the Transportation Research Institute of the University of California in the United States, and some applications have also been made in China. For example, the Ningbo road speed analysis system uses the technical achievements of the German Aerospace Center. [0003] (1) FCD-based road trip speed analysis technology [0004] Japan and Germany hav...
