Electronic Control System for Securing the Entry and Exit of Passengers in Public Transportation Buses

The research seeks to improve passenger safety when boarding and alighting from public transportation buses in Metropolitan Lima, since there is no system that guarantees their protection at these critical moments. An electronic control system composed of two main subsystems was designed to achieve this objective. The first one blocks the bus acceleration system while the doors are open, preventing the vehicle from moving forward under these conditions. The second controls the locking of the doors, allowing them to open only when the bus is completely stopped and preventing them from closing if any obstacle impedes the process. To develop this system, the operation of the acceleration system and the pneumatic system of the doors w as studied, and an open-loop control was implemented, using a PIC microcontroller to process the signals. The system was tested in a 2013 Cummins engine public bus, with satisfactory results, increasing passenger safety.
