Method and apparatus for collecting real-time traffic information

Abstract

The invention discloses a method for collecting real-time traffic information. A dumb short message target receiving object is screened from base station users; a dumb short message is sent to the dumb short message target receiving object and user location information of the dumb short message target receiving object is captured by a dumb short message response; network signaling data including the user location information is extracted from a mobile terminal network; and the network signaling data are processed to obtain real-time road condition data. In addition, the invention also discloses an apparatus for collecting real-time traffic information.

Description

Technical field [0001] The invention relates to information collection technology, in particular to a method and device for collecting real-time traffic information. Background technique [0002] Intelligent transportation system is a general term for transportation systems that use video systems and communication systems for intelligent analysis and route selection for the purpose of alleviating road congestion and reducing traffic accidents. Traffic information data collection is the primary link in the construction of an intelligent transportation system. Using traffic information data can effectively help users optimize travel paths and avoid traffic congestion. [0003] Traditional road network monitoring data collection technologies mainly include ground sensing coils, GPS / Beidou floating vehicles, video surveillance, ultrasonic detectors, microwave detectors, and infrared detectors. Although these instruments can measure real-time traffic information of road sections, The a...

Problems solved by technology

However, this application cannot find that the user has updated to a new cell location in a certain time granularity, and when processing massive data, the calculation efficiency of real-time acquisition of road condition information is not as ideal as calculation using big data technology, and there are bottlenecks in performance expansion

[0007] In the prior art, mobile phones are used as traffic detectors, but there are following defects in the real-time traffic information collection of mobile phone network signaling: 1. The enrichment of real-time location information of mobile users is very important for road condition analysis, but due to technical specifications It is agreed that when a user leaves a cell and registers with other adjacent cells under the same LAC without any communication behavior, no cell change data of the user will be generated in the core network; therefore, in the core network The information captured at the layer level shows that the user is still located in the old cell, and it becomes an urgent problem to be solved to find out the user’s location update in a certain time granularity.

2. Mobile network signaling has a large amount of data and requires high real-time performance. Existing technologies have performance and expansion bottlenecks in processing large data
