The experience of the US DOT has led to the definition of an Intelligent Transportation Infrastructure (ITI) consisting of traffic detection and monitoring, communications, and control systems required to support a variety of ITS products and services in metropolitan and rural areas. Whether infrastructure is deployed by the public sector, the private sector or a combination of the two depends on the locality. The ITI provides the building blocks needed to effectively deploy and operate, as locally appropriate: traffic signal control systems, freeway management systems, transit management systems, incident management systems, electronic fare payment systems, electronic toll collection systems and multimodal traveler information systems. Signifigant benefits have been recorded using ITI in areas such as accident reduction, time savings, transit customer service, roadway capacity, emission reduction, fuel consumption and vehicle stops. |
