Work zones cause congestion and result in more than 800 fatalities and 37,000 injuries in the U.S. every year. The increasing maintenance and rehabilitation of our aging infrastructure, combined with the growing travel and congestion on our roads, heightens the need for finding new ways to enhance mobility and safety in work zones. Forward-looking transportation agencies across the country are using ITS to make travel through and around the work zones safer and more efficient.
To better identify and document uses and benefits of ITS in work zones, the FHWA's ITS Joint Program Office conducted a cross-cutting study examining the application of ITS in work zones at sites in four states:
- Springfield, Illinois I-55
- Lansing, Michigan I-496
- Albuquerque, New Mexico I-40/I-25
- West Memphis, Arkansas I-40
All four sites employed ITS for monitoring and managing traffic and for providing traveler information. One site also used ITS for incident management. The purpose of the study was to share with other regions the experiences of early deployers of ITS in work zones.
