DIKSUCHI 3366
The Sumith's Diksuchi-3366 Vehicle Mounted Unit (VMU) has built-in GSM and GPS modules which provide real time information of the vehicle. It detects next stop, arriving stop and current stop, displays text on the internal display board and also makes audio announcement. It sends selected route information to outer LED display boards for passengers. The VMU sends real time location information, alerts/SoS etc., to the back-end servers which in turn can be used to generate reports required.
