摘要：Many a times the warning sign on the road sides becomes difficult to watch for the drivers and the drivermay sometimes miss the warning notes. These warning notes may be speed breaker ahead or narrow bridge or evenaccident zone etc. This becomes tedious during rainy seasons and at nights. Sometimes the boards may be so dirty andthe driver may not read anything and even if he tries to read it with a wide eye there is a chance for the drive to loseconcentration on the road. For this a portable unit is placed inside the vehicles and it communicates with the roadsidesystems at all times. So the position of each vehicle can be very easily known by the roadside system and also the systemhas all the details of roads and emergency station such as hospitals stored in it. So whenever the information is neededsuch information is automatically passed on to the vehicle from roadside system and the driver in the vehicle can get aclear idea of the contents received. The microcontroller used is a high Speed PIC microcontroller for fault freeoperation. It has a variety of advantages over conventional old microcontrollers such as RISC architecture, largermemory word, fast operation and a host of inbuilt features such as ADC, communication protocols etc.,. A GPS systemis placed along with the microcontroller. The GPS system gives the exact position of the vehicle by giving out itslatitude and longitude. The microcontroller at all times receives the information and displays the informationusing the dedicated LCD display. Further the same is used to announce to the driver about the hurdles such as speedbreakers. This voice alerting system helps the drivers to concentrate on the road without even worrying about the signboards near the road.
