Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic data service systems face instability and potential interference in vehicle control due to communication disruptions among vehicles, leading to deficiencies in data transmission and compromised traffic flow.
Innovation Solution
A traffic control system that includes a vehicle control apparatus and a traffic control apparatus, which transmit and receive travel environment data, and utilize data supplementation to maintain stable traffic flow even when communication is disrupted by determining the supplementability of data from nearby vehicles and generating supplementary traffic environment data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic control system collects data from multiple vehicles, then traffic environment data completeness is improved, but system reliability deteriorates when communication disruptions occur
Solution Approach 1:
The system performs preliminary actions by collecting and storing travel environment data from multiple vehicles before communication disruptions occur. The traffic control apparatus accumulates data in advance, creating a data reservoir that can be drawn upon when communication failures happen, ensuring continuous operation without data gaps
Solution Approach 2:
The traffic control apparatus acts as an intermediary that mediates between multiple vehicle data sources and individual vehicles. It collects data from all vehicles, processes it centrally, and distributes supplemented data back to vehicles, ensuring data completeness even when individual vehicle-to-infrastructure communication fails
2Stability of the object's composition
If traffic control system transmits data to all vehicles, then traffic flow stability is improved, but data transmission reliability deteriorates due to communication disruptions
Solution Approach 1:
The system implements feedback by continuously monitoring communication status of each vehicle and adjusting data transmission strategies accordingly. When communication disruptions are detected, the traffic control apparatus uses data from nearby vehicles with successful communication to supplement and maintain accurate traffic environment information for all vehicles
Solution Approach 2:
The traffic control apparatus creates copies of traffic environment data from vehicles with successful communication and distributes these copies to vehicles experiencing communication disruptions. This ensures all vehicles receive consistent traffic flow information without direct communication with the traffic control apparatus
3Reliability
If vehicle control apparatus uses traffic environment data for travel control, then travel safety is improved, but system vulnerability increases due to communication disruptions
Solution Approach 1:
The system applies beforehand cushioning by preparing supplementary data mechanisms in advance of communication disruptions. The traffic control apparatus and nearby vehicles are positioned to provide data cushioning that protects against the harmful effects of communication failures, ensuring travel safety is maintained through alternative data sources
Data Source
AI summary
A traffic control system includes a vehicle control apparatus and a traffic control apparatus. The vehicle control apparatus includes a travel environment data transmission unit and a travel control unit. The traffic control apparatus includes a data supplementability determination unit and a data supplementation unit. The data supplementability determination unit determines whether or not data regarding a communication-disrupted vehicle out of a plurality of vehicles is supplementable on the basis of travel environment data received from a nearby vehicle traveling near the communication-disrupted vehicle. The data supplementation unit generates traffic environment data supplemented with the data regarding the communication-disrupted vehicle, on the basis of the travel environment data received from the nearby vehicle, and transmits the traffic environment data generated, to the nearby vehicle.
