Abstract
This invention pertains to: a method for controlling the monitoring of broadcast messages of traffic information, and reporting to a user, traffic information that relates to a set of user-specified routes of travel; and also to a travel route information monitor that operates in accordance with the method. The method includes a first step of programming information into a controller (1). A first portion of the programmed information specifies a time. A second portion of the programmed information specifies a set of geographical routes of travel comprising a primary route and at least one alternative route. A next step includes initiating the receiving of broadcast messages of traffic information at a time that is a function of the time specified by the first portion of the programmed information. A next step includes screening received broadcast messages to collect traffic information that relates to any of the routes of travel specified by the second portion of the programmed information. A next step includes reporting the collected traffic information to a user.
