With the continuing advances in wireless communications, geo-positioning, and portable electronics, an infrastructure is emerging
that enables the delivery of on-line, location-enabled services to very large numbers of mobile users. A typical usage situation
for mobile services is one characterized by a small screen and no keyboard, and by the service being only a secondary focus
of the user. Under such circumstances, it is particularly important to deliver the “right” information and service at the
right time, with as little user interaction as possible. This may be achieved by making services context aware. Mobile users
frequently follow the same route to a destination as they did during previous trips to the destination, and the route and
destination constitute important aspects of the context for a range of services. This paper presents key concepts underlying
a software component that identifies and accumulates the routes of a user along with their usage patterns and that makes the
routes available to services. The problems associated with of route recording are analyzed, and algorithms that solve the
problems are presented. Experiences from using the component on logs of GPS positions acquired from vehicles traveling within
a real road network are reported.
