Abstract

The invention, which belongs to the field of traffic big data application, discloses an urban traffic situation sensing method and a visualization method. According to the invention, urban floating car GPS data, electric police pass data, video monitoring data and mobile phone signaling data are transmitted to a big data analysis platform in real time; with utilization of video recognition, big data analysis, data fusion, internet, visualization and other technologies, multi-source traffic data fusion is realized; precise macroscopic, mesoscopic and microscopic parameters including the urban traffic operation index, road segment driving speed, and intersection flowing capacity and the like are obtained; and different levels of parameters reflecting the urban traffic situation are displayedat one map by using a visualized interface. Therefore, the comprehensive, full-space-time, full-coverage urban traffic operation situation is displayed precisely.

Description

technical field [0001] The invention relates to an urban traffic operation parameter extraction and visualization method, in particular to an urban traffic situation awareness method and a visualization method, belonging to the field of traffic big data applications. Background technique [0002] According to statistics from the Traffic Management Bureau of the Ministry of Public Security, the number of motor vehicles in the country reached 12.19 million in 2003. As of September 2016, the number of motor vehicles in the country reached 280 million, an increase of more than 20 times compared with 2003. Rapid growth. Due to the lack of effective means to fully grasp the operation status of urban traffic, the rapid increase of motor vehicles has brought problems such as traffic congestion, frequent traffic accidents, and excessive pressure on public transport. Especially in big cities such as Beijing and Shanghai, traffic emergencies will not only cause large-scale traffic par...
