Managing Emergency Situations in VANET Through Heterogeneous Technologies Cooperation

Area of Science:

• Vehicular computing
• Wireless communication protocols
• Road safety technologies

Background:

• Vehicular computing research has significantly advanced vehicle security and comfort through new services and protocols.
• IEEE 802.11p (Wireless Access in Vehicular Environments - WAVE) and Dedicated Short Range Communication (DSRC) standards enable integration of new vehicular technologies.
• Significant investment from public and private sectors highlights the growing importance of vehicular technologies.

Purpose of the Study:

• To design a novel approach for vehicular environments to gather real-time information using on-board sensors.
• To alert vehicles about dangerous or emergency situations encountered during transit.
• To leverage existing communication standards for disseminating critical safety information.

Main Methods:

• Vehicles equipped with on-board units (OBUs) featuring sensors and Global Position System (GPS).
• OBUs collect environmental data, identify obstacles, accidents, or emergencies.
• Information is shared with surrounding road-side units (RSUs) using standard communication protocols (WAVE/DSRC).

Main Results:

• The system effectively gathers information about the vehicle's surroundings, including potential hazards.
• Alerting messages regarding dangerous situations are disseminated through the vehicular network.
• Accurate event location is determined and broadcast using GPS data.

Conclusions:

• The proposed system enhances road safety by providing timely warnings of hazardous conditions.
• Vehicles receiving alerts can proactively avoid dangerous situations and potential accidents.
• This approach contributes to a more secure and efficient transportation environment.
