Road-vehicle Communication System for Toll Road Reverse-way Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road-vehicle communication systems are inefficient in preventing reverse-way traveling accidents on toll roads, as they provide warnings to all vehicles, potentially annoying forward-traveling drivers and not specifically targeting vehicles likely to travel in reverse.
Innovation Solution
A road-vehicle communication system with two roadside apparatuses and an administration device that identifies and stores vehicle identification and type information, providing reverse-way traveling warnings only to vehicles expected to travel in reverse, using DSRC communication to guide vehicles correctly and prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning is transmitted to all vehicles passing through the roadside apparatus, then reverse-way traveling prevention coverage is improved, but driver annoyance increases and system efficiency deteriorates
Solution Approach 1:
The system applies different warning strategies to different vehicles based on their specific characteristics and behaviors. Vehicles that have entered the toll road are identified and targeted for reverse-way warnings, while normal forward-traveling vehicles are not disturbed. This localized approach improves efficiency by avoiding unnecessary warnings to all vehicles.
Solution Approach 2:
The system uses feedback from the vehicle identification and tracking process to dynamically adjust warning delivery. By monitoring which vehicles have entered the toll road through the first roadside apparatus and comparing this with vehicles detected by the second roadside apparatus, the system intelligently determines which vehicles need warnings, thereby improving overall system efficiency.
2Reliability
If warning is transmitted to all vehicles, then reverse-way traveling prevention coverage is improved, but driver annoyance increases
Solution Approach 1:
The system delivers warnings only to specific vehicles that have a high probability of reverse-way traveling, rather than broadcasting to all vehicles. This targeted approach maintains high prevention coverage while minimizing annoyance to drivers who are correctly traveling forward.
Solution Approach 2:
The system performs preliminary identification and tracking of vehicles that have entered the toll road before issuing warnings. By pre-screening vehicles through the first roadside apparatus and maintaining a record of entered vehicles, the system can proactively warn only those vehicles that might inadvertently travel in reverse, avoiding unnecessary warnings to other drivers.

AI summary
First and second roadside apparatuses for short-range communication with a vehicle-mounted device mounted in a vehicle are disposed upstream and downstream of a one-way road. The first and second roadside apparatuses installed on the road acquire vehicle identification information for identifying the vehicle when the vehicle passes through the communicative areas thereof. A administration device capable of communicating with the first and second roadside apparatuses stores the vehicle identification information acquired by the first roadside apparatus in a storage unit. If the vehicle identification information acquired by the second roadside apparatus is not included in the vehicle identification information stored in the storage unit, the administration device provides the vehicle with a reverse-way driving warning information through the second roadside apparatus. Thus, the road-vehicle communication system for warning a vehicle being driven or fully expected to be driven in the reverse-way on a one-way road such as a toll road against the reverse-way driving.
