Long duration incidents had the greatest opportunities for delay, emissions, and fuel consumption reduction from ITS deployments in Michigan.

Simulations of ITS BenefitsThe objective of corridor microsimulation was to quantify detailed benefits resulting from MDOT ITS deployments (DMS, CCTV, detectors, travel time signs, TOCs). In this…
Taxonomy: Dynamic Message Signs, Detectors, Imaging / Video

Highway segments with dynamic message signs found to have 16.6 percent fewer crashes than those segments without the signs.

MethodologyThe study team analyzed the safety impact of ITS devices on crashes by developing a negative binomial model. The analyses looked at segments with DMS or other ITS devices. The crash…

Collisions on I-5 in Washington State have been reduced by 65-75 percent in a 7.5 mile corridor where an active traffic management system was deployed.

WSDOT deployed a series of 15 sign bridges every half-mile over a 7.5 mile stretch of I-5 between Boeing Access Road and I-90 in Seattle. These sign bridges hold dynamic message signs, which display…
