In any unlikely event of accidents or vehicle breakdown, there is accumulation of traffic which results in road-blockage and causes in convenience to other vehicles. If this happens in remote areas, the accidents victims are left unattended and there is delay in providing emergency services. In case of traffic, it obstructs the entry of ambulance and rescue team which results in death of passengers. To prevent this mishap, a mechatronics based road block avoiding and accident alarming system is designed which is automated by the use of sensors. The road-block is detected with the help of PIR based motion detectors which are placed at regular intervals on road. This input is given to a Local Control Unit (LCU) which is integrated on every road. This LCU sends live feed from PIR sensors and reports the accident to the Main Control Unit (MCU) which is located at the nearest police station. A single MCU covers the area administered by that police station and each road in that area has one LCU. Additional CCTV cameras are present to give graphical view of accident. The MCU sends SOS signal to Traffic department, nearest Hospital and currently running ambulances. They are informed about the location of the site through GPS which helps in immediate rescue. There is also a group of small modular retractable robots which blocks the nearest entrance of the road to prevent further traffic accumulation. These robots are present along the side of road and are controlled by LCU. The MCU informs GPS satellites about the accident and hence it diverts other vehicles to an alternate route preventing blockage. This system works automatically and provides instantaneous information which helps in providing emergency services.
