How will we know if the SW Washington HOV lane is working?
The operation of the HOV lane will be evaluated on an ongoing basis by WSDOT, according to established traffic engineering standards. Adjustments to the operation of the lane will be made as necessary. Measures of a successful HOV lane include whether it carries more people per hour than the adjacent general purpose lanes; if it saves HOV users at least five minutes or one minute per mile on their one-way commute; and if it does not worsen overall traffic congestion and delay.
