Most of the road accidents occur due to the drivers drive vehicles at high speed even in speed limited area such as traffic signals, school zones, hilly regions, highly curved paths without considering the traffic rules. The traffic police are not able to control them with full effect and thus lead to major accidents at traffic signals. This work mainly aims at automatically controlling the speed of vehicles at speed restricted place like traffic signal and the prevention of accident is done by ultrasonic sensor. It is used to get information from other vehicles. The controller units calculate the distance and makes the decision on processed data. Index Terms:speed control, accident prevention, motor driver, autonomous cruise control I. INTRODUCTION Nowadays, the increase of the transportations like car, bus and two wheelers in major cities of world raise a need to avoid accident in our society. The increasing number of vehicles has increases the accident rate. To control and monitor the speed of vehicles on traffic signals the respective departments of government has taken necessary step[1-7]. But it’s not doing enough. So that automation of speed control at traffic signal is introduced. It is also called as traffic-aware cruise control or dynamic radar cruise control. It is an advanced cruise control system that adjusts the vehicle speed automatically for preventing the vehicle from accident and also maintains a safe driving. This can be controlled by using sensor based information from on-board sensors such as RF module and ultrasonic sensor that allowing the vehicle to slow down or stop when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to proceed, also use vibration sensor to detect accidents. II. METHODOLOGY The ultimate goal of this work is to reduce the speed of the vehicle while violating the traffic signal rules and also prevent accidents by using of ultrasonic sensor. This workhaving three blocks, first block is at traffic section second one is at vehicle 1 unit and the last one is at vehicle 2 unit. For real time application the traffic section is fitted in everytraffic signal and other two sections are fixed in all vehicles. The Arduino Uno is used extensively across all blocks.

Arduino is based on microcontroller board designsto implement various functions. It consists of digital and analog input/output(I/O) pins that can interfacing various external boards and other circuits. This provides an additional feature such as Universal Serial Bus (USB) for loading programs from computer systems. The Arduino provides an integrated development environment (IDE) based on a programming languages such as C and C++. A. TRAFFIC SECTION: In traffic section unit, ArduinoMicrocontroller (ATmega328) is used. This will control theoverall functional unit. Figure:Traffic section The Arduinomicrocontroller gives the informational input to the traffic signal. Based on the given input the traffic signal color and time delay for the signal will be determined. The encoder is used in the traffic section because to avoid any frequency mismatches during processing (we use RF transmitter and receiver whose frequency is 433.3 MHz). Due to possibility of interference from other similar frequency communication, the use of encoder is essential. Then RF transmitter sends all the data (time delay, traffic signal ID etc.,) to the vehicles.
