The traffic congestion problems are the phenomenon which contributed huge impact to the transportation system. Ambulance service is always affected by traffic. So many important schedules get delayed due to these traffic jams. To solve this problem we have decided to make “A wireless traffic control system with patient monitoring ambulance”. In this, we will collect the patient’s health conditions with following parameters such as heart beat, body temperature, pressure etc. This parameters are collect, displayed on LCD and are send to authorized mobile phone using GSM module. This system is also designed to operate the traffic light, when it receives signals from an emergency vehicle whose signal transmissions are based on radio frequency (RF). According to this project, when patient’s parameters exceed the normal values then the sensor will detect the signal and sends it to PIC microcontroller. The microcontroller will send the alert message through the GSM to an authorized mobile number, which will help in providing better facilities to the patient.
