Intelligent Transportation Systems (ITS) Architecture

General Description:

ITS projects make use of electronics, communications, or information processing to improve the efficiency or safety of a surface transportation system.  Because information technology is generally most effective when systems are integrated and interoperable, the United States Department of Transportation (US DOT) has established the National ITS Architecture to provide a common structure for the design of ITS projects.  The National Architecture describes what types of interfaces could exist between ITS components and how they will exchange information and work together to deliver ITS user service requirements. (source: U.S. DOT-FHWA/FTA)

Effects of Solution:

¨ Increase Passenger Throughput

¨ Increase Roadway Capacity

þ Manage System Efficiency (ITS inform travelers of current conditions, alternate routes, etc.)

¨ Reduce Local Demand

There are a host of ITS solutions.  Refer to the ITS section of the Fact Sheets for specific technologies. 

Examples of Implementation:

Refer to the ITS section of the Fact Sheets for specific technologies.

Cost/Financial Information:
