Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion.
Intersection assistants use two radar sensors in the front bumper and sides of the car to monitor if there are any oncoming cars at intersections, highway exits, or car parks. [23] This system alerts the driver of any upcoming traffic from the vehicle's sides and can enact the vehicle's emergency braking system to prevent the collision. [23]

AEB systems aim to detect possible collisions with the car in front. [50] This is performed using sensors to detect and classify things in front of the vehicle, a system to interpret the data from the sensors, and a braking system which can work autonomously. [51] Some cars may implement lane departure warning systems. [52]
Volvo introduced the lane departure warning system and the driver alert control on its 2008 model-year S80, the V70, and XC70 executive cars. [22] Volvo's lane departure warning system uses a camera to track road markings and sound an alarm when drivers depart their lane without signaling.
Gradually, existing systems were stabilized, followed by the introduction of disc brakes and anti-lock braking systems. High-tech safety systems were first introduced in 1995 with Electronic Stability Control (ESC). Lane departure warning systems were introduced in the year 1999, and radar assisted adaptive cruise control was introduced in 2005.
This system was first introduced on the 2001 Volvo SCC concept car, then placed into production on the 2003 Volvo XC90 SUV and produced a visible alert when a car entered the blind spot while a driver was switching lanes, using cameras and radar sensors mounted on the door mirror housings to check the blind spot area for an impending collision ...
