The Main Aim Of This Project Is To Implement A Rash Driving-detection System In Cities That Alerts Traffic Control Authorities Wirelessly In Case Of Speed Violation By Any Vehicle. Nowadays, Accidents Are Taking Place Frequently In The Cities Due To Over Speeding Of Vehicles Resulting In Many Casualties. In The Current Systems, To Detect Rash Driving, Policemen Use A Handheld Radar Gun To Record Vehicle Speed. Our Proposed System Fulfills That Requirement Through Wireless Mechanism As It Consists Of Two Blocks: Transmitter And Receiver; Both Use A Microcontroller Of The PIC Family And A Rectified-power Supply. This Project Consists Of An RF Transceiver Module Operating At 2.4 GHz. Relative Rash Driving Is Detected By The Sensor Which Is Interfaced To The Microcontroller At The Transmitting End And By Using The Appropriate Control Signals And Equipments, The Traffic Authorities Are Notified
