Abstract---This paper proposes an intelligent lane
brake system, speed sensor, and other automatic systems. But these cars are not affordable by everyone. So, this system is developed which can be implemented in every vehicle.
clearance and collision avoidance system as a prototype, which avoids delay and crashing of ERVs (EMERGENCY RESPONSE VEHICLE) and provides greatest security to the ERVs. Here ultrasonic sensor is used to continuously track for any obstacle. If the obstacle is detected then microcontroller will continuously compare the distance given by the ultrasonic sensor. If the obstacle is closer to the ERVs then a control signal is sent to the nearby vehicle and its speed is controlled by the microcontroller placed in the obstacle. The lane clearance is done based on the warning signals given to the nearby vehicles. A warning display unit and sound producing unit is placed on the dashboard of the vehicles. Here RF transmitter and receiver are used to communicate between the two microcontrollers.
This system consists of sensors that are placed in the ERV and warning systems are placed within the vehicles which provide warning to the driver about the approaching of ERVs. There is a two level warning system for lane clearance. The warning signals are issued by the ERV driver. It is done by using the selection buttons mounted on the dashboard of the ERV. The warning signal is displayed on the LCD screen and also a sound-producing unit is mounted on the dashboard of the vehicle produces maximum sound which alerts the driver. It helps in the cases when driver fails to respond to the warning displayed on the LCD screen. And coming to collision avoidance the ultrasonic sensor will measure the distance in reference to the preceding car. If the distance measured is less than the permissible limits then a control signal is sent to the nearby vehicle microcontroller then the speed of the vehicle is limited. A good example of the system is how it works when an ERV driver is about to change lanes and there is an obstacle in his blind spot. The sensor will detect that obstacle, calculates the distance and control signal is given to the vehicle he start turning his car, and prevent him from getting into serious accident.

I.INTRODUCTION There are several advanced technology and innovations are available for vehicle safety. Even though there are advanced technological innovations for vehicle safety, the growth in number of accidents and increase in death rate due to delay is continuously increasing. And these accidents are due to collision or intersectional accidents and due to delay in reaching the accident spots and to hospitals. Delay of ERVs is because of vehicles not giving side this is because of mainly two reasons. They are car’s audio and sound isolation may prevent a driver from hearing an ERV siren. Collision of vehicles occurs due to mistakes done by driver and intersectional accidents are caused due to bad weather conditions and over-speeding. Hence, to overcome these mistakes an intelligence collision avoidance and lane clearance system is proposed. Only sports cars and other luxury vehicles consist of antilock

There is lot of techniques available for lane clearance, distance measurements and to avoid collision but the one technique which is introduced in our system is effective and cheap by using ultrasonic sensor. Ultrasonic sensor is used to measure the distance in reference to the preceding car. Hence the collision can be avoided by using ultrasonic sensor. In our proposed system we use RF-434Mhz Tx and
