Abstract:
1. A traffic information computer system comprising: a data storage database for obtaining data from users and holding said data for generating roadmaps and a traffic database storing average speed data for road segments; a display screen; a first transceiver; a microprocessor programmed to generate roadmaps from data held within said mapping database, to display said roadmaps on said display screen, to receive average speed data for road segments through said first transceiver, to store said average speed data for road segments received through said first transceiver to said traffic database, and to display portions of said average speed data for road segments stored within said traffic database in locations corresponding to said road segments on said display screen; a location sensor for determining locations of said computer system as said computer system is moved along with a vehicle, wherein said microprocessor is additionally programmed to calculate periodically an average speed of movement in response to location data provided by said location sensor at a number of predetermined times and to transmit said average speed of movement over said first transceiver; and wherein said microprocessor is additionally programmed to display an icon on a road segment displayed on said display screen in a location corresponding with a location indicated by an output of said location sensor and in an orientation indicating a direction of travel of said traffic information computer system.
