Abstract - An In today’s fast moving world vehicles are
the Geographical Information Systems (GIS) to assess threat levels for driver if approaching the curved road quickly. But these maps need to be updated regularly and are not useful if there are unexpected road diversions or extensions etc. We propose a dynamic model where the system controls the speed of the automobile according to the data in the frame that is transmitted by the RF transmitter fixed to the nearby signal unit. RF transceivers are kept in the vehicles which receive the speed limit as RF signals from the signal unit. The officials in the control unit can control the speed of a traffic zone by setting the speed limit and notifying the signal unit as a SMS with the help of GSM modems kept in the control unit and the signal unit, which in turn signals the vehicle unit transceiver.
getting extremely numbered and as a result traffic jams and accidents are very common. Rash driving and over speed of vehicles lead to the demise of many people. Hence automation of speed control of the vehicle is the vital need of today’s world. Our project "External Adaptive Speed Controlling System" is aimed at automatically controlling the speed of the vehicles at heavy traffic zones and critical areas like school zone, hospital zone etc. This system will help us to avoid traffic jams and accidents due to high speed of vehicles. The speed control of vehicles is done using RF (Radio Frequency) technology. RF transmitters/receivers are placed in traffic zones and vehicles. When vehicle enters these zones RF communication occurs and speed is controlled automatically. An additional feature provided by our system is that the traffic officials can control the traffic in particular zones by sitting in their offices itself. That is real time control of traffic is made easier. The officials can set the speed limit for a particular zone for a fixed time. This is made possible by using GSM network. The speed limit is send by the official using GSM modem as a message. Then the speed of the vehicle is reduced to that value in the message.
The above mentioned vehicle unit implementation happens in real time, where as in our system we setup an model of vehicle unit and with help of a remote unit we control the speed of this vehicle model. This model can also be better utilized to improve the fuel efficiency by imposing the maximum speed limit on the automobiles at which the mileage will be more.
2. DESIGN OF THE SYSTEM Adaptive Speed Controlling system is a dynamic model where the system controls the speed of the automobile according to the data in the frame that is transmitted by the RF transmitter fixed to the nearby signal unit. The transmitter will send RF signals to the vehicle unit from the signal unit about the speed limit once the vehicle is within the traffic zone. RF transceivers are kept in the vehicles which receive the speed limit as RF signals from the signal unit. The officials in the control unit can control the speed of a traffic zone by setting the speed limit and notifying the signal unit as a SMS with the help of GSM modems kept in the control unit and the signal unit, which in turn signals the vehicle unit transceiver.

1.INTRODUCTION We know road accidents are increasing day by day, most of which are caused because the vehicles are driven at high speeds even in the places where sharp turnings and junctions exist. Reduction of number of such accidents is the prime step needed to be taken.Many systems have been developed to prevent these road accidents. One of them is the Cruise control system (CC) that is capable of maintaining speed defined by the driver and its later evolution version Adaptive Cruise Control (ACC)[1] that keeps the automobile at safer distance from the preceding vehicle. But these systems have no capability to detect the curved roads where the speeds of the auto mobiles have to be lowered to avoid the accidents. Later curve warning systems (CWS) have been developed to detect the curved roads by using Global Positioning System (GPS) and the digital maps obtained from

The modules of the system include: vehicle unit, signal unit, control unit, remote unit. The above mentioned vehicle unit implementation happens in real time, where as in our system we setup an model of vehicle unit and with help of a remote unit we control the speed of this vehicle model. Here the remote unit is used for our system as we are not doing real time implementation. Hence the system proposed will have four modules which depend upon GSM technology, RF technology and PWM. The above mentioned vehicle unit implementation happens in real time, where as in our system we setup a model of
