Effective deployment of ITS technologies depends in part on the knowledge of which technologies will most effectively address the issues of congestion and safety. Thus, it is important to understand the benefits or risks of both existing and emerging technologies. Based on documented experience locally and throughout the country, ITS deployments in urban areas have the potential to offer the following benefits:
• Arterial management systems can potentially reduce delays with the implementation of advanced control systems and traveler information dissemination.
• Freeway management systems can reduce the occurrence of crashes, increase capacity, and decrease overall travel times.
• Freight management systems reduce costs to motor carriers with the implementation of the commercial vehicle information systems and networks.
• Transit management systems may reduce travel times and increased reliability with automatic vehicle location and transit signal priority implementation.
• Incident management systems potentially reduce incident duration and offer numerous other benefits.
There is a wide range of benefits that can be obtained from ITS deployments. For example, fuel consumption, travel time, and delay can be reduced. ITS deployments can also result in higher travel speeds, improved traffic flow, and more satisfied travelers for all modes.
