States to conduct field operational tests on variable speed limits - Public Information and Information Exchange

Public Roads, May-June, 2002

FHWA awarded cooperative agreements to Maryland, Michigan, and Virginia to implement and analyze the effectiveness of variable speed limits in work zones.

Variable speed limit systems rely on input of vehicle speeds and other information to post an appropriate speed limit, enabling motorists to maintain the most efficient and safe speeds, without endangering themselves, other drivers, or workers. Each of the selected States will implement the systems in a work zone, monitor operations, and evaluate the effectiveness. The results from these pilot projects will be distributed to all States, so best practices for safe and efficient travel through works zones may be applied.
