Answer:
The goal of intelligent transportation systems (ITS) is to improve the effectiveness,
efficiency, and safety of the transportation system. 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 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 between 5% and 40%
with the implementation of advanced control systems and traveler information
dissemination.
• Freeway management systems can reduce the occurrence of crashes by up to
40%, increase capacity, and decrease overall travel times by up to 60%.
• Freight management systems reduce costs to motor carriers by 35% with the
implementation of the commercial vehicle information systems and networks.
• Transit management systems may reduce travel times by up to 50% and increased
reliability by 35% with automatic vehicle location and transit signal priority
implementation.
• Incident management systems potentially reduce incident duration by 40% and
offer numerous other benefits, such as increased public support for DOT activities
and goodwill.
