Embodiment Construction

[0015] There are three main parts of mobile phone data related to user privacy:

[0016] 1. The user's mobile phone number (or the unique identifier IMSI of the mobile phone)

[0017] 2. The user's travel route, because through the user's track location information, it can reveal which sensitive places the user has been to, and then judge the user's medical condition, political orientation and love relationship and other private information

[0018] 3. User call information, call information includes when and how long the user dialed which number, and then can determine the privacy information between the user and the dialed number

[0019] Aiming at these three kinds of privacy information, the present invention provides a traffic flow monitoring method capable of protecting the privacy of mobile phone users while utilizing mobile phone communication data.

[0020] The present invention first establishes a virtual travel route model based on mobile phone communication data. ...

Abstract

The invention belongs to the technical field of urban traffic management, and relates to a road traffic flow monitoring method considering privacy protection, comprising: plotting mobile communication base stations on a map according to coordinate information of mobile communication base stations; dividing the map into many Polygon, ensure that the points on the side of the polygon are equal to the distance from the surrounding base stations; at the intersection of the polygon and the road on the map, make a line segment perpendicular to the road, marked as a virtual travel line VTL, and two adjacent virtual travel lines form a VTL pair; information screening of mobile phone communication data; encryption processing of reserved mobile phone numbers or IMSI; statistics of observation data between each VTL pair to realize traffic flow monitoring. The invention can protect the user's private data and obtain effective information in the data, thereby realizing the traffic flow monitoring by using the mobile information data.

Description

technical field [0001] The invention belongs to the technical field of urban traffic management and relates to a traffic flow monitoring method. Background technique [0002] In recent years, with the continuous development of our country's economy and the continuous acceleration of our country's urbanization process, the problem of urban traffic congestion has become increasingly serious and common, which has had a profound impact on the social production and social life of urban people. First of all, in the process of traffic congestion, a large amount of fuel is wasted in vain, causing serious economic losses; secondly, a lot of people's time was wasted, causing great losses. At the same time, when an emergency occurs, the traffic congestion problem greatly reduces the emergency response speed, causing many unnecessary economic property and even the loss of people's lives. Therefore, it is very necessary to monitor and warn road traffic flow and provide real-time road in...
