POTENTIAL USE OF PUGET SOUND HOV LANES BY GENERAL PURPOSE VEHICLES IN OFF-PEAK HOURS A SUMMARY PAPER The Puget Sound region has some of the most severe traffic congestion in the country. To help combat this congestion, the region has built one of the nation’s most extensive and successful HOV systems.

During peak commute periods. Off-peak traffic volumes in the Puget Sound region of Washington State are increasing, and public concern about congestion during non-commute periods has caused WSDOT to re-examine the current policy of restricting HOV lanes to transit vehicles and carpools 24 hours.

Weekend traffic volumes in the Puget Sound region of Washington State are increasing, and public concern about congestion during non-commute periods has caused WSDOT to re-examine the current policy of restricting high occupancy vehicle (HOV) lanes to transit vehicles and carpools 24 hours per day, 7 days per week.

Full Document (pdf KB) Authors: Mark E. Hallenbeck, John M. Ishimaru, Jennifer Nee. Originator: Washington State Transportation Center (TRAC) Publication Date: Monday, J High occupancy vehicle (HOV) lanes are travel lanes designated solely for non-single occupancy vehicle (SOV) automobiles (such as 2 or more people/vehicle) and transit vehicles.

Free-flow highway lanes can be designated HOV lanes during certain hours of the day (peak periods) or designated HOV lanes for all hours of the day. HOV lanes encourage. Remedy for Under-Performing HOV Lanes: In some areas there has been increasing pressure to convert under performing HOV lanes to general purpose use.

HOT lane applications have the potential to increase the number of vehicles traveling on underutilized facilities and possibly reduce pressure to convert them to general-purpose use. According to WSDOT’s website, bus drivers who use the lanes will be specially trained.

Authorized transit buses will be able to use the inside southbound lane to bypass congestion in the adjacent HOV lanes. The shoulder lanes are expected to reduce bus travel times by minutes, and potentially more depending on traffic congestion.

HOT lane applications have the potential to increase the number of vehicles traveling on underutilized HOV facilities and possibly reduce pressure to convert them to general-purpose use. In New Jersey a few years ago, before the HOT lane treatment became prominent, the governor converted some HOV lanes to general purpose lanes.

Weekend traffic volumes in the Puget Sound region of Washington State are increasing, and public concern about congestion during non-commute periods has caused the Washington State Department of Transportation (WSDOT) to re-examine the current policy of restricting high occupancy vehicle (HOV) lanes to transit vehicles and carpools 24 hours per day, 7 days.

Flex Pass set to HOV mode. the Puget Sound region grew by 86, people jobs. general purpose lanes continue to be more. Ewing () estimates that HOV facilities can reduce peak-period vehicle trips on individual facilities by %, and up to 30% on very congested highways if HOV lanes are separated from general-purpose lanes by a barrier.

One study estimates that HOV lanes can reduce up to % of VMT and up to % of vehicle trips in a region (Apogee ). Interstate is a major congested freeway in Alameda County. It has one high-occupancy vehicle (HOV) lane plus three contiguous mixed flow lanes in each direction for approximately 17 miles, from just south of Oakland to Fremont.

This corridor has the highest volume of. The Express Lanes carry over 40 percent of the total SR traffic during heavily congested periods, even though they comprise only one-third of the total freeway capacity.

This amounts to a 33 percent higher throughout per Express Lane, relative to the general-purpose lanes. A CONVERTING HOV LANES TO HOT LANES. Operational Projects. San Diego's Priced Express Lanes on I San Diego's "FasTrak" pricing program was implemented in April Under this program, customers in single-occupant vehicles pay a toll each time they use the Interstate 15 HOV lanes.

“lumpiness” of HOV lanes: HOV lanes must be allocated a whole number of lanes (e.g. 1 lane, 2 lanes, etc) and must be reserved for part icular numbers of passengers per car (e.g., HOV These are the first HOV lanes in Kitsap County and they may or may not achieve their purpose.

They are considered a four-year test project, but that deadline has more to do with the unusual placement of the HOV lanes on the outside of the highway than it does with the general concept of HOV lanes and their benefits.

the major motivating factor in initiating HOV lanes (4). Although exact calculations are difficult be­ c~use of changes in the number of lanes over a given section of freeway or in hours of operation, traffic volumes on freeways before HOV treatment generally exceed 1, vehicles per lane per hour during the.

Sound Transit rendering. Standing up to demands for perpetual privilege, WSDOT has informed the city of Mercer Island that its year special access to high occupancy lanes will end in that time, the I express lanes will permanently close for the 6-year construction of East Link, and additional HOV lanes will be added in the main roadway between Mercer.

The $ million SR Eastside Transit and HOV Project rebuilds the highway from Medina to Bellevue into a six-lane facility with two general-purpose lanes and a transit/HOV lane in each direction. where l is the individual's marginal utility of income, V m is the individual's indirect utility of all m choices, p 0 indicates the initial point (i.e., before the policy change), and p f indicates the final point (i.e, after the policy change).

The change in indirect utility is converted to dollars by the factor, 1/ l, or the inverse of the individual's marginal utility of income. lanes have averaged 60 mph and above while speeds in the general purpose lanes average above 50 mph during peak congestion.

Discussion. The four-year HOT lanes pilot project to provide single occupant vehicles the option of paying to use HOV lanes started in May The average number of daily tolled HOT trips has increased.

The letter also suggests a long list of operational changes. Most notably, WSDOT is to consider “re-instating” a general purpose lane on NB I between SR and NE 70th St, where an exit lane was converted to general purpose use to make room for the ETL.

HOT lanes currently operate in San Diego, CA, and Houston, TX. Under the San Diego pricing program that began in ,motorists in single-occupant vehicles pay a toll each time they use the I HOV lanes. The HOT lanes were the brainchild of Jan Goldsmith, former assemblyman and mayor of Poway, CA.

"There was a lot of resistance to the idea of. section that had two reversible lanes separated by a barrier from general purpose traffic and an 8-mile section that had one lane in each direction separated from general purpose traffic by double-white stripes.

the Puget Sound region grew by. The bridge itself does not have a dedicated bus lane, but it does have the next best thing: HOV 3+ lanes. Convincing WSDOT to convert an HOV 2 lane to HOV 3 is like pulling teeth, but the bridge has them today.

Furthermore, all vehicles (including HOV 3+) are subject to a toll, which is an additional incentive to get people to take transit.

Most vehicles using the lane are 2-person carpools. In several other metropolitan areas, HOV lanes carry much higher numbers of buses in peak periods and, as a result, deliver more persons per hour. An HOV lane on the Shirley Highway (I) between Northern Virginia and Washington, D.C., carries persons per hour.

By many measures, the lanes have been a success. At peak, each express lane carries more vehicles than each general-purpose lane. In some places, vehicle throughput in the tolled lanes is up to 30% greater than the regular lanes.

Overall, the busiest parts of the corridor are now transporting 20% more vehicles, or 30% more people, than before. “It seems like the only logical HOV restrictions should occur Monday thru Friday between about 3 p.m. to p.m., which would allow early and late leaving shipyard workers to use the lane.” Bob also cited shipyard workers required to come early or stay late who are unable to car pool as disadvantaged by the hour enforcement.

Early evaluations in San Diego (I FasTrak) and Houston (US and I QuickRide) indicated that HOV to HOT conversions can increase lane use by 21 to 24 percent and save HOT lanes users 11 to 20 minutes in travel time.

Impacts on general purpose lanes were positive in Houston and Minneapolis (I peak period speeds were up 15 percent). the state, up to eight hours of congestion each day • Byemployment will grow by 50% and the area will see 25% more residents. Crowded HOV lanes • I HOV lanes are not meeting state and federal requirements to operate at 45 miles per hour 90 percent of the time • I HOV lanes are often just as congested as the regular lanes.

HOV facility. Even if a vehicle accesses the HOV lane via a direct access ramp and immediately merges into a general purpose lane, that vehicle is using the HOV facility and is subject to 23 USC and Observations on History Mr. Lancaster's letter provides an insightful summary of the history of this issue, dating back to the The relative rarity of high-occupancy vehicles compared to single occupancy vehicles—estimated at 7% [citation needed] of the traffic—in the United States and Canada makes HOV lanes work for the drivers who can use them.

When it is uncongested, an HOV lane can move at full speed even when parallel (non-HOV) lanes suffer delays from queueing at. direction from SR to I-5 (two general purpose lanes and one HOV lane), and two lanes in each direction west of I It includes five interchanges at SRValley Avenue E., I-5, 54th Avenue E.

and SR Truck weigh stations and two park-and-ride lots are also included. The extension fills a critical link missing in.

The plan defines operational strategies to include traveler information systems, safety enhancements, ramp metering in peak hours, service patrols and incident response teams, signal timing and HOV lanes, and improving advanced technology applications for commercial vehicles.

About 81% of HOV lanes carry below vehicles per hour per lane during peak hours. Providing HOV lane usage for carpooling vehicles (which can. The HOV lanes in the Seattle area have traditionally been restricted to HOVs 24 hours a day, seven days a week (24/7).

While there is strong public support for HOV lanes and heavy peak period use of HOV lanes, there has also been vocal public support for allowing single-occupant vehicles (SOVs)to use HOV lanes during off-peak periods. At 2 p.m. Monday, Ap the I northbound peak-use shoulder lane will officially open to general-purpose traffic on the mile stretch between State Route and I Between now and then, we're wrapping up our testing of the new electronic signs that will control the lanes, so you might still see some test messages, symbols and.A right-side shoulder was opened to general-purpose traffic on I in Northern Virginia during the same hours that a left- side general-purpose lane was restricted for HOV-only use (see Figure 20).

One or more facility types may be found in a .most effective use of the system. x Convert HOV lanes to HOV/tolled express lanes to optimize performance and maintain free-flowing service for transit, vanpools, and carpools.

Medium Term (within 20 years) Consider potential for building additional capacity as tolled express lanes through more extensive study of long-term costs and benefits.
