Mobile Terminal Cluster Traffic Information Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic information services rely on a large number of probe cars to provide real-time data, which is costly and inefficient, as they require significant maintenance and resources to operate effectively.
Innovation Solution
A method and apparatus utilizing mobile communication terminals with GPS capabilities to form clusters, collect, and transmit traffic information to a server, allowing multiple terminals to collaborate and reduce the need for individual data collection by each vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of probe cars are used to collect traffic information, then real-time traffic situation data can be provided, but maintenance cost and resource consumption increase significantly
Solution Approach 1:
The patent transforms mobile communication terminals from single-function devices into multi-functional units that simultaneously provide communication services and traffic information collection. By integrating GPS receivers and communication modules into existing mobile terminals, the system enables these devices to serve dual purposes: personal communication and traffic data gathering, thereby eliminating the need for dedicated probe cars
Solution Approach 2:
The system enables mobile communication terminals to automatically collect and transmit traffic information without requiring dedicated maintenance personnel or specialized infrastructure. The terminals autonomously perform location tracking via GPS, data collection, and transmission to servers, making the traffic information gathering process self-sufficient and reducing operational overhead
2Productivity
If dedicated probe cars are deployed for traffic information collection, then traffic data can be gathered systematically, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent merges traffic information collection functionality with existing mobile communication terminals. By combining GPS reception, location tracking, and communication capabilities into devices that users already possess and maintain, the system eliminates the need for separate probe car infrastructure, thereby reducing device complexity and maintenance requirements while maintaining collection efficiency
3Quantity of substance
If multiple mobile communication terminals form clusters to collect traffic information, then cost of maintaining separate devices is reduced, but coordination and communication overhead increases
Solution Approach 1:
The patent introduces a server as an intermediary that coordinates cluster operations and manages traffic information collection. The server receives location and traffic data from mobile terminals, processes the information, and manages cluster formations, thereby simplifying the coordination mechanism and reducing the complexity burden on individual terminal devices
Data Source
AI summary
A method and apparatus for providing a traffic information service using a mobile communication terminal are provided. A method of a mobile communication terminal for a traffic information service is provided. The method includes constructing a cluster with at least one neighboring Mobile Station (MS), receiving traffic information from the at least one neighboring MS comprised in the cluster, measuring traffic information using location information of the MS, and transmitting a traffic information message comprising the collected traffic information to a traffic information provision server.
