Intelligent vehicle communication system/The second part

In these systems, equipment on cars And special places are installed on the side of the roads, which provide the possibility of communicating wirelessly between cars and between cars and roadside equipment.. By exchanging sensitive information such as position, speed and direction of movement cars To a certain extent, drivers of cars equipped with these systems (Related cars) They have a higher level of awareness of the cars around them and can make informed decisions by receiving timely information to deal with dangerous situations and avoid getting into accident-causing situations..

In general, applications based on automotive communication technology are categorized into two parts:

Car-to-car communications (V2V‌)

• Cars with electronic equipment called “In-vehicle unit” or “Car status display unit” (OBU), wirelessly and based on a communication technology like “Dedicated short-range communication protocol” (DSRC) They exchange messages with each other. These messages using the information received from the sensors inside the car (including speedometer, accelerometer, satellite locator, ABS system brake sensor and …) And according to Standard Certain are produced.

Vehicle communication with infrastructure (V2I​​)

• Message exchange between vehicles and infrastructure communication network using equipment called “Roadside units” (RSU) takes place. In this section, tracking data cars And information such as timing of traffic lights, weather data and road traffic conditions are collected by roadside units and appropriate messages are sent to vehicles passing through the area covered by roadside units.. The messages sent to the cars are generated and used based on the analysis of the information collected in the control and monitoring center of the roadside units..

By using V2V and V2I communication applications with the aim of improving the level safety, increasing mobility and Improve fuel efficiency Cars are defined in these systems, which is the ultimate goal of using these systems.

The applications of the system in the V2I sector, which has been tested as a pilot, include:

– Electronic payment of vehicle tolls,
– Prioritizing passage for public and emergency vehicles at assumed intersections.
– tracking passing vehicles and collecting traffic data,
– warning of the entry of the car from the side road to the main road,
– Announcing the traffic situation of the road in the places out of the driver's sight in the assumed places,
– Announcing the condition of the road in terms of meteorological phenomena and traffic restrictions,
– Updating variable message boards

as well as system applications in the V2V sector, including:

-Announcing the sudden stop of the car,
-Warning the passing of the emergency vehicle to the vehicles on the road.
-Event announcement car accident
