Authenticated Traffic Control and Security

This paper presents a new design to control the speed of the automobiles at remote places for fixed time. Generally, in automobiles throttle position is controlled by the Electronic Control Unit (ECU) mainly according to the one of the inputs received from the accelerator’s Pedal position sensor. But in the proposed model, instead of ECU, another Microcontroller unit receives the pedal position from the sensor and then Microcontroller unit transfers to the ECU. The Microcontroller unit is also interfaced with the wireless module that is capable of detecting any other transceiver. Now, the automobile can be controlled at the desired places when we deploy the transmitters that send data frames with fields containing maximum speed and time for which this speed limitation is to be imposed. In this system the speed of the particular zones can be set by a official by sitting in his office through GSM network the new set speed is updated to the signals. This system can also be implemented in no parking areas whenever the vehicle get parked in a no parking area driver receives a alert and if he doesn’t respond then the vehicle id will be sent to the authorities through the GSM network and the vehicle get arrested and driver has to pay the fine for retrieval of the vehicle. This system can also be implemented in Zebra crossing while vehicle approaching the zebra line if someone is ready to cross then the system will sent a alert signal to Car and the car get stopped at the zebra line for pedestrian crossing . An ultrasonic sensor is equipped in car to find the obstacle in front section and this avoid collision of the vehicle .A keypad is included in vehicle to detect theft whenever the password is typed wrong three times then an alert signal is produced through buzzer.
