Embodiment Construction

[0087] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0088] The embodiment of the present invention adopts the signaling record in the mobile communication network, the road condition record reported by the vehicle detector and the GPS position record reported by the floating vehicle. The collected signaling records on expressways in Fujian Province come from China Mobile, the largest mobile communication operator in China. A signaling record includes: user ID (encrypted), date and time, location area code (LocationArea Code, LAC), cell ID (Cell ID), signaling type (01 voice, 02 SMS, 03 data service, 04 cut-in cell, 05 to cut out the cell, 06 to periodically update the location, 07 to switch on and off, etc.).

[0089] The signaling processing server with real-time signaling data access is located ...

Abstract

The invention discloses a real-time highway road condition information acquiring method based on data fusion, and belongs to the field of intelligent traffic. A vehicle velocity estimation method based on three kinds of data fusion is given by taking highway vehicle velocity based on mobile phone signaling estimation as basic data and combining data obtained from an induction coil type vehicle inspection device and GPS positioning data of floating vehicles (such as passenger vehicles, highway passenger vehicles and hazardous material transportation vehicles). According to the method, existing mobile communication facilities and vehicle inspection device resources are fully utilized, additional detection devices do not need to be installed, road condition estimation covering the whole road network can be obtained at low cost, and all-weather real-time road condition collection is achieved. The method is accurate in estimated road condition result, easy to popularize and suitable for highways.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a method for acquiring road condition information of expressways in real time based on data fusion. Background technique [0002] The Internet of Vehicles is a network that integrates automobiles, the Internet of Things, and the mobile Internet. In such a network environment, a large amount of dynamic and static data related to people, vehicles, roads, and the environment will be generated. Making full use of and mining these data can provide travel services for the public, provide monitoring services for vehicles and logistics for the transportation industry, and provide auxiliary decision-making for urban management. [0003] In the Internet of Vehicles environment, traffic information can be sensed by using data from special detection equipment (such as ring induction coils, radars, and cameras) installed in fixed locations. For expressways, although the ...
