Washington state HOV system
• Planned 320 mile system in the
Central Puget Sound Region
• Approximately 220 miles
• Very well utilized during peak
• Operations:
• Continuous access
• 2+ occupancy requirement
(with a few exceptions)
• I-5 HOV lanes operate 24/7
• Other HOV lanes operate 5
am to 7 pm
• Double-white lines in some
places to prevent unsafe
SR 167 HOT Lane Features
• Free to buses, 2+ carpools and
• Solo drivers pay a single toll to
travel any distance on 10-mile
Pre-HOT lanes:
SR 167 had two
general purpose
lanes and one
HOV lane.
• Single HOT lane in each
• HOT lane separated from GP
lanes by double-white line,
which is illegal to cross.
• Electronic signs indicate the toll
rate before each entry point
• 10 access points
Post HOT lanes: HOV lanes were converted to a single
HOT lane in each direction.
Why restricted access on SR 167?
Reduces Toll Evasion
Improved Safety
Helps Enforcement
Serves the long trips
• A Freeway within a Freeway
• It was what everyone else was doing!
Future plans: converting HOV to HOT
• Regional plans call for converting all
HOV lanes to HOT lanes by 2020
• WSDOT currently conducting an
express toll lanes pre-design study
• Options range from converting
existing HOV lane to converting
HOV lane and use shoulder
during peaks for a dual lane
• Challenges
• Space for buffer separation is
limited if not impossible
• Location of congestion is very
dynamic and varies between AM
and PM (in both directions)
What we have learned…
• Additional signage needed
• Modified access points
• No significant change in safety
• University of Washington
• As congestion increases, violations increase.
• Drivers want to get into the lane when the reach the start of the queue
• Very few instances of toll avoidance
• On-going complaints – Top 3
• Access
• Signing
• Access
MnDOT’s 35W HOT lanes
• I-394 implemented with
• 80% buffer separated
• 20% open access
• I-35W implemented with
• 20% buffer separated
• 80% open access
Discussion Goals
• Open vs. Restricted Access
– Revenue impacts
– Safety impacts
– Speed impacts
– Volume impacts
– Trip length impacts
– Double vs. single lane – different treatments
– Future flexibility
Discussion Topics
What is the real speed differential between HOT lanes and GP lanes?
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?
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?
Long distance vs. anyone who wants to pay?
Safety Research
6 of one, half dozen of the other?
How much is local driver behavior a factor?
