Problems solved by technology

[0005] Among them, when the active scheme is used to collect traffic information, a large number of mobile stations need to be sampled, and active traffic information collection schemes such as Paging will greatly increase the network transmission load; while when the passive scheme is used to collect traffic information, if the traffic congestion is serious, the speed of the vehicle will be extremely high. low, the call duration of the vehicle-mounted mobile station is less than the time required to pass through two consecutive switching points in the road segment, and it is impossible to obtain enough switching sample size to estimate the travel speed of the road segment

Abstract

The present invention provides a location information collection device, traffic condition estimation system and method, wherein the location information collection method includes: during the process of the mobile communication terminal initiating active communication, collecting the mobile communication terminal based on the mobile network side positioning technology the first data of the mobile communication terminal; by actively paging the mobile communication terminal, and collecting the second data of the mobile communication terminal based on the paging based on the mobile network side positioning technology; collecting the first data according to a mode selection parameter Selecting at least one of the data and collecting the second data, and controlling the selected step of collecting data to be in a working state; sending the data collected by the data collecting step in the working state to the data analysis terminal, so that the data analysis terminal can be based on The received data is used for traffic condition estimation. The invention combines active and passive collection methods to collect location information and estimate traffic conditions.

Description

technical field [0001] The invention relates to the fields of mobile communication and traffic information collection, in particular to a position information collection device, a traffic condition estimation system and a method. Background technique [0002] Existing schemes for collecting traffic information based on mobile communication networks can be divided into active traffic information collection and passive traffic information collection according to whether new signals need to be generated during the collection process; according to the subject of positioning, they can be divided into mobile network-based solutions. traffic information collection and traffic information collection based on mobile terminals. [0003] Typical active traffic information collection includes technical solutions based on Paging (paging). The accuracy of this technical solution based on Paging (paging) and the real-time performance of its information depend on: sampling frequency, positi...
