Conversion of an HOV lane to a HOT lane in Washington State allowed for a 3 to 19 percent increase in speeds in general purpose lanes despite a 2 to 3 percent increase in volumes in the general lanes.
In May 2008, WSDOT opened an approximately 10 mile stretch of SR167 as HOT lanes converted from HOV lanes. On average, since the opening of the HOT lanes, HOT lane volumes have increased 19 percent…

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…

An infrared detection system deployed in a mobile van correctly identified vehicles that need to be taken off the road 44 percent of the time; an improvement over using random selection alone.
FindingsBy using the thermal eye van, Washington State has been able to be more selective of which trucks they inspect for equipment violations, such as faulty breaks. This method results in follow…
