A safety message dissemination method in a travel guidance system

Area of Science:

• Intelligent Transportation Systems
• Network Communication

Background:

• Traditional Vehicular Ad Hoc Networks (VANETs) for accident alerts cause broadcast storms.
• Existing methods often disseminate safety messages widely, leading to inefficiency.

Purpose of the Study:

• To propose a novel method for broadcasting road accident messages within a Travel Guidance System (TGS).
• To eliminate broadcast storms and unnecessary message dissemination.

Main Methods:

• Accident messages are sent from the vehicle to a central transport system via 5G.
• The transport center identifies and notifies only vehicles affected by the accident.
• Vehicles use pre-stored alternative routes from their On-Board Unit (OBU) to avoid the incident.

Main Results:

• The proposed TGS method avoids the need for vehicles to form ad hoc networks.
• It precisely targets only the vehicles influenced by the road accident.
• Redundant and unnecessary message dissemination is thoroughly removed.

Conclusions:

• This TGS approach effectively prevents broadcast storms in accident notification systems.
• It offers a targeted and efficient solution for real-time traffic management during incidents.
