Traffic System Control Using Accident Notifications for Pile-Up Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic systems struggle to prevent additional vehicles from being involved in accidents, particularly pile-ups, especially under conditions of poor road conditions or bad weather, which can't be completely avoided and pose a danger to other vehicles due to road blockage.
Innovation Solution
A method for controlling a traffic system that includes receiving accident notifications from vehicles involved in an accident, determining a pile-up based on the number of notifications within a predefined distance, and providing a warning to approaching vehicles with risk characteristics, allowing them to take appropriate actions to avoid the accident.

Engineering Contradiction Analysis
1Reliability
If a driver relies on visual detection of accidents or sensors detect accidents in autonomous vehicles, then accident detection can be achieved, but the detection is delayed and additional vehicles may be involved in pile-ups
Solution Approach 1:
The system performs preliminary action by detecting accidents through vehicle sensors (accelerometers, gyroscopes) and immediately notifying a central control entity before the accident becomes visible to other drivers or detectable by their sensors. This advance detection and notification system allows approaching vehicles to be warned and take evasive action before reaching the accident scene, preventing pile-ups.
2Reliability
If accident notifications are sent to all vehicles, then more vehicles can be warned, but false alarms increase when multiple unrelated accidents occur
Solution Approach 1:
The system uses feedback by continuously monitoring accident notifications from multiple vehicles and analyzing their spatial and temporal relationships. When multiple notifications are received, the system evaluates whether they indicate a single pile-up accident or multiple unrelated incidents based on location data and timing, then adjusts warning transmissions accordingly to avoid false alarms while maintaining comprehensive coverage.
Solution Approach 2:
The central control entity acts as an intermediary that receives, processes, and validates accident notifications before forwarding warnings to approaching vehicles. This intermediary layer analyzes the consistency and pattern of notifications to distinguish between genuine pile-up scenarios requiring warnings and isolated incidents that do not, thereby reducing false alarms while maintaining system reliability.
3Reliability
If early warning is provided to approaching vehicles, then pile-up prevention is improved, but the system complexity and computational requirements increase
Solution Approach 1:
The system segments the traffic network into zones based on proximity to detected accidents. Instead of implementing complex real-time analysis across the entire network, the central control entity divides the road system into affected zones (where warnings are sent) and unaffected zones, applying simplified warning logic to each segment. This segmentation reduces overall system complexity while maintaining effective pile-up prevention in critical areas.

AI summary
The disclosure relates to a method for controlling a traffic system comprising at least a first vehicle (14) and a second vehicle (26), wherein each of the first vehicle (14) and the second vehicle (26) is travelling on a road. The method comprises receiving an accident notification (N) from the first vehicle (14), determining an amount of received accident notifications (N), comparing the amount of received accident notifications (N) with a threshold amount and determining that a pile-up accident (11) has occurred if the amount of received accident notifications (N) equals or exceeds the threshold amount. Subsequently, a pile-up accident warning (W) is provided to the second vehicle (26). Furthermore, the disclosure relates to a corresponding data processing apparatus (42) and a corresponding computer program (50). Furthermore, the disclosure is directed to a method for controlling a first vehicle (14) and a method for controlling a second vehicle (26). Moreover, a further data processing apparatus (12, 28) a vehicle (14, 26) and a traffic control system (54) are presented.
