Summary:A passenger information system (PIS) called TUTPIS has been
developed for networking passengers with companies that provide public
transport services. TUTPIS supports a passenger with personalised, real
time information services in all phases of a journey. Services include
timetables, travel route searching, route reservations, and electronic
payment. TUTPIS is targeted to operate on the developing wireless
network infrastructure of mobile, local, and personal networking
technologies. A TUTPIS model concentrating on bus services has been
implemented using the specification and description language (SDL). The
model contains functional implementations of a TUTPIS server and mobile
terminals. In addition, the behaviour of external entities, such as
buses, trains, and third party systems is implemented for simulations.
By simulations, the operability of TUTPIS can be verified and
performance estimations for system servers, wireless network
throughputs, and mobile terminals derived
