Vehicle Location and Arrival Time Wireless Messaging System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers waiting for buses or taxis face inefficiencies due to lack of real-time location and arrival time information, leading to wasted time and resources, as current wireless communication systems fail to effectively provide dynamic updates considering changing traffic conditions.
Innovation Solution
A wireless communication system equipped with a GPS device on vehicles that sends location and estimated arrival time information to passengers' mobile devices via short messages, emails, or voice messages, using a traffic message center that processes real-time traffic data to provide accurate updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless communication system transmits real-time vehicle location and arrival time information to passengers, then passenger convenience and time management improve, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent introduces a message center as an intermediary component that receives vehicle location data from GPS devices, processes the information, and distributes it to multiple passengers via wireless communication. This mediator architecture simplifies the overall system by centralizing data processing and avoiding direct peer-to-peer communication between vehicles and numerous passenger devices.
Solution Approach 2:
The system enables passengers to proactively request arrival time information by sending requests to the message center, which then automatically responds with relevant data. This self-service approach allows passengers to obtain information on-demand without requiring continuous broadcasting from the vehicle, reducing unnecessary communication overhead.
2Loss of time
If the system provides accurate real-time arrival time estimates considering traffic conditions, then waiting time for passengers is reduced, but data processing requirements and energy consumption increase
Solution Approach 1:
The system updates vehicle location information and sends notifications to passengers at periodic intervals rather than continuously. The message center receives GPS data at regular intervals, processes arrival time estimates, and transmits updates only when significant changes occur, thereby reducing energy consumption while maintaining useful information flow.
Solution Approach 2:
The system implements feedback mechanisms where the message center receives vehicle location data, calculates estimated arrival times, and sends this information back to passengers. The system also handles passenger requests for specific arrival time information, creating a feedback loop that provides accurate, on-demand updates without requiring continuous high-energy transmission.
