Abstract:
Most of the age-old tractor-trailers were not fitted with proper indicators such as stoplight or tail light. As a result, the vehicle behind the trailer cannot know the direction of the tractor-trailer during turning, and it leads to accidents in road march. For example, when the trailer turns right, the driver must first swing to the left to get enough clearance to execute a right turn safely. The trailer can hit a vehicle in the adjacent lane when it is not done properly, sometimes crushing the vehicle between the trailers. To overcome these types of difficulties, the development of wireless turning indicators for agricultural tractor-trailer systems to ensure safety was considered. The system consists of a safe wireless radio frequency module, transmitter circuit, receiver circuit, and lighting system. The braking system was provided with a stoplight at the rear of the trailer, which emits red light intended to warn of the vehicles slowing down or stopping. The system was evaluated and concluded that cent percent of the drivers can visualize and drive safely after installing tail lights in the trailers.
