Data processing apparatus for probe traffic information and data processing system and method for probe traffic information

Abstract

There provide a data processing system of probe traffic information which can generate nation-wide traffic congestion information with a small amount of investment, by generating traffic congestion information about the roads by estimating the location of a cellular phone, using information of connection and disconnection of the cellular phone with a base station, using the location information for the probe data and matching with road map data. The traffic congestion information on road is generated by using a cellular phone of a driver or a fellow passenger, collecting location information of a cellular phone obtained by transmission with a base station (when talking, and polling when not talking) and receiving it as probe data, and matching it with the road map data. When the a commercial vehicle of a driver having a cellular phone does not move within the range predicted in advance, more accurate traffic congestion information is generated, by determining whether the location data of the cellular phone is suitable as a probe information.

Description

technical field [0001] The present invention relates to a traffic information generation system using detection information, in particular to a data processing system for detection traffic information, a data processing device for detection traffic information, and a data processing method for detection traffic information. The mobile phone whose position is estimated is used as a probe terminal, the position of the terminal is used as probe data, and traffic information using map data is generated based on the position information in the area for specifying the base station of the mobile phone. Background technique [0002] In order to effectively use the navigation system of a car to calculate the shortest time route from the current point to the destination, not only map information but also road congestion information of the planned route is required. In order to generate this road congestion information, it is necessary to monitor the movement of cars running on the roa...

Problems solved by technology

[0006] The traffic state estimation method and traffic state estimation / providing system of Patent Document 1 In order to obtain probe information by effectively utilizing probe car data, it is necessary to install a GPS receiver on the target car, and use a communication unit such as a mobile phone to utilize the GPS receiver. The location information obtained by the receiver is transmitted to the detection center, and the collected information is accumulated in the detection center to generate traffic information, so there is a problem that communication costs are required
