Problem solution

Problem & Solution

  • I-394 opens in 1992 with HOV lanes funded by Feds

  • Problem

    • Funding for new construction is limited

    • Congestion continues to grow

    • I-394 perception: Is HOV lane half empty or half full?

  • 2002 Twin Cities HOV Study

    • HOV lanes operating at less than full potential

    • During peak, HOV lanes (3,053) are typically moving more people per lane than general-purpose lanes (2,076)

    • FHWA urged changes, but opening HOV lane to all traffic not permitted

      Solution: MnPASS Express Lanes


I 394 mnpass project goals

I-394 MnPASS Project Goals

  • Improve I-394 efficiency

  • Maintain free flow speeds for transit and carpoolers

  • Use revenues to improve highway and transit in corridor

  • Employ new technologies for pricing and enforcement


Orientation

Orientation

  • 11 mile corridor

    • 3 mile barrier separated reversible section

    • 8 mile diamond lane section

  • 5 EB and 6 WB access points in diamond section

  • HOVs, transit and motorcycles free

  • Fully electronic & dynamically priced


Toll collection

Set up a pre-paid MnPASS account

Install transponder

Antennae reads transponder in vehicle

Toll Collection


Technology tolling antenna

Technology - Tolling Antenna

  • Approximate antenna weight = 10 lbs

  • Multiple antenna readers are used over each HOT lane.

  • Antenna readers are located at five locations along HOT lanes.


High compliance

Access Control- Crash Condition


Dynamic pricing works

Dynamic Pricing Works

  • Price based on congestion in HOT lane

    • Set based on customized rate tables

    • Data collected every 30 seconds

    • Toll updated every 3 min using 6 min avg


Dynamic pricing works1

Dynamic Pricing Works

Toll ranges $0.25 - $8.00 max

  • Overall average $1.10 (March 2007)

  • Peak average $1.00 - $4.00

  • Off-peak average $0.25 per section

  • EB average $1.37

  • WB average $0.76


Peak period transit ridership 6 to 9 am 3 to 6 pm

Peak Period Transit Ridership(6 to 9 AM, 3 to 6 PM)

  • External issues impacting transit

  • Transit operators indicate:

    • Access points improve safety for drivers

    • Express lanes remain free flowing

Source: Mn/DOT HOV Quarterly Reports


Enforcement

Enforcement

  • Increased enforcement thru partnerships with:

    • Minneapolis Police Department

    • Golden Valley Police Department

    • Minnesota State Patrol

  • Petty misdemeanor with $142 fine

  • Initial planning and equipment cost of $250K

  • 8 hrs of enforcement on weekdays (annual cost of $165K)


Mnpass enforcement

MnPASS Enforcement


Year 1 enforcement results

Year 1 Enforcement Results

  • Over 3,300 enforcement stops

  • 50% of stops involved HOV or double white line crossing violations

  • I-394 violations dropped by 50%

  • HOV violations on I-394 are much lower than on I-35W


Safety 12 decrease in crashes

Safety: 12% Decrease in Crashes

Average 2003-05 =560

* Compares data for year starting May 16 to May 15 of the next year

Speeds and Usage

  • Travel speeds in the general purpose lanes increased by 2% to 15%

  • Peak hour volumes increased 7 to 30%, while miles of congestion decreased

  • 95% of time speeds above 50 mph (required to be above 45 mph 90% of time)

  • Eastbound has 52% of trips and 65% of revenue

  • Heavy usage days: Tue, Wed, Thu

  • 70% of trips start or end in reversible road


Mnpass toll users

MnPASS Toll Users

  • 30% of transponders used on a typical day

    • Average user makes two tolled trips per week

  • Usage Higher Among

    • Full-time workers

    • Homeowners

    • Ages 35-55

    • Incomes over $50,000

    • Women


Mnpass user satisfaction
