2Washington state HOV system Planned 320 mile system in the Central Puget Sound RegionApproximately 220 miles builtVery well utilized during peak periodsOperations:Continuous access2+ occupancy requirement (with a few exceptions)I-5 HOV lanes operate 24/7Other HOV lanes operate 5 am to 7 pmDouble-white lines in some places to prevent unsafe maneuvers.
3SR 167 had two general purpose lanes and one HOV lane. SR 167 HOT Lane FeaturesFree to buses, 2+ carpools and motorcyclesSolo drivers pay a single toll to travel any distance on 10-mile routeSingle HOT lane in each directionHOT lane separated from GP lanes by double-white line, which is illegal to cross.Electronic signs indicate the toll rate before each entry point10 access pointsPre-HOT lanes:SR 167 had two general purpose lanes and one HOV lane.Post HOT lanes: HOV lanes were converted to a single HOT lane in each direction.
4Why restricted access on SR 167? Reduces Toll EvasionImproved SafetyHelps EnforcementServes the long tripsA Freeway within a FreewayIt was what everyone else was doing!
5Future plans: converting HOV to HOT Regional plans call for converting all HOV lanes to HOT lanes by 2020WSDOT currently conducting an express toll lanes pre-design studyOptions range from converting existing HOV lane to converting HOV lane and use shoulder during peaks for a dual lane systemChallengesSpace for buffer separation is limited if not impossibleLocation of congestion is very dynamic and varies between AM and PM (in both directions)
6What we have learned… Additional signage needed Modified access points No significant change in safetyUniversity of WashingtonAs congestion increases, violations increase.Drivers want to get into the lane when the reach the start of the queueVery few instances of toll avoidanceOn-going complaints – Top 3AccessSigning
7MnDOT’s 35W HOT lanes I-394 implemented with 80% buffer separated 20% open accessI-35W implemented with20% buffer separated80% open access
8Discussion Goals Open vs. Restricted Access Revenue impacts Safety impactsSpeed impactsVolume impactsTrip length impactsDouble vs. single lane – different treatmentsFuture flexibility
9Discussion TopicsWhat is the real speed differential between HOT lanes and GP lanes?Does it matter if it’s a single HOT lane verses a dual HOT lane?What additional space is needed if any within the cross-section of a HOT lane?Are there facts on toll avoidance tendencies?What do you hear from your customers as it relates to access?What revenue impacts are there with more access?Can your gross revenue be more or less?What trips should be served in the HOT lanes?Long distance vs. anyone who wants to pay?Safety Research6 of one, half dozen of the other?How much is local driver behavior a factor?
