The motoring public experiences the effects of growing traffic congestion as increasing delays, accidents, and environmental pollution. One way that transportation engineers are seeking solutions to the problems of road congestion is by exploring alternative technologies within the framework of Transportation Systems Management (TSM) strategies. One of the strategies that has great potential for relieving congestion on road networks is the implementation of real-time information systems which, in a broad sense, is any combination of hardware and software that provides information to motorists during the course of their trip. The benefits provided from real-time traveler information can positively impact the operation of all transportation services and will lead to improvements in highway traffic operation and mobility as a whole. The information provided to the motorist could be warning, regulatory or informative in nature and can be delivered in either a static or dynamic format. The major drawback of the static systems is their inability to adapt to changing traffic conditions. These factors, therefore, are addressed in the implementation of dynamic systems in which real, or almost real-time information is supplied to motorists during the course of their trip. |
