Information server for bus operators

TUTPIS is a large-scale information system being developed for companies that provide public transport services and their customers. TUTPIS is targeted for national services, concerning taxis, buses, and trains as the main means of conveyance. This paper presents the functionality and implementation of a TUTPIS server targeted for bus operators. The server receives real-time information through cellular data network from active buses, processes the received data, and produces different types of reports for TUTPIS users. An operational TUTPIS server has been implemented. The implementation is made on Linux PCs using the Java 2 Enterprise Edition (J2EE). The TUTPIS server has been evaluated in practice with a limited number of buses in Finland during the fall 2002. In addition, performance testing has been carried out to find out the capacity of TUTPIS platform. These tests have shown that the server provides adequate performance for TUTPIS services. The server development continues by extended functionality for both bus operators and passengers.
