Urban Traffic Monitoring, Navigation, and Guidance to Alleviate Urban Traffic Congestion

Abstract

Traffic congestion in urban area seems to be rapidly spreading in space and in time. A few years ago, roads surrounded the central business district of any metropolitan areas had hardly any traffic at all. But now, thousands of commuters crowd in there and try to find shortcuts from their suburban homes to their suburban office destinations. Traffic congestion is spreading to the entire highway network instead of the main radial corridors from downtown. Similarly, the traditional rush hours during the morning and afternoon in the urban area disappeared and have been replaced by a high plateau rush hour which continues from early morning to evening.
