A travel information system broadcasts a stream of traffic event information relative to a given road network and a information collecting devices carried in vehicles travelling within the road network each filter among the stream of traffic event information to display only those traffic events relative to a selected travel route of the host vehicle. Each stored travel route is defined by placing the information device in a learn mode to collect a sequence of current vehicle position values during travel along the route. The information device need not include a costly and difficult to maintain large scale database representing the road network. The device thereby constructs and maintains a collection of frequent travel routes specific to the vehicle carrying the device and need not be updated to reflect changes in the road network, but rather allows the user to simply redefine the stored travel routes in light of current road usage and route selection.
