The Dynamic Passenger Information System (SDIP) is an integrated information system that provides passengers with information on the performance of public transport services and makes it available to supervisory services. The primary purpose of the SDIP system is to provide passengers with information on the estimated departure time of a vehicle operating a specific line from a selected stop. Departure time information is communicated to passengers and displayed via a system of display panels (LED/LCD). Information presented on electronic media includes the stop name, line number, estimated and/or scheduled departure time, special announcements (information on traffic disruptions, detours, ticket prices, etc.), and advertisements.
