A Status onLarge Scale Truck Separationin the
United States
Presentation to FHWAs Talking Freight Seminar
on Truck Separated Lanes/Truck Tolling March 16,
2005 Arno Hart Wilbur Smith Associates
2
Various Concepts
Grade Separated
New Mixed-flow or HOV Lanes
Tolled Truck Lanes
Truck Climbing Lanes
3
Need for additional freightcapacity on highways
State DOTs are starting to recognize.
4
National I-10 Freight Corridor
5
New freight policy directions.
Despite need for continued focus on modal
DIVERSION
Truck traffic is expected to grow
Also need policies to ACCOMMODATE trucks

1. Innovations in highway development
2. Innovations in truck mobility/operations

Propel Trucks thru Bottlenecks
Focus onTrucks

• Move in mass
• Like rail and barge

Maintain their service advantage

• Door to door
• Run anywhere on the system

MassFlowConcept
TRUCK PLATOONS

• Research is on going
• Auto Separated Highway System

Separation of trucks can provide additional

DEVELOPMENT TRUCK ONLY LANES
Candidate Selection 3 Principal Criteria
Daily Truck Volume
Volume Capacity Ratios
Total Daily Volume
Plus Service Sensitivity
10
SELECTION TRUCK ONLY LANES

• 4 Candidates
• LA-Inland Empire
• Phoenix-Tucson
• Houston West
• Gulf Coast

High volumes v/cs
Developing problems
Strong central tendencies
Rational start/end points

Scenario 3 Truck-Only Lanes
(Impact along affected segments of corridor)
Car Speed Improvements
Deficient Mileage - Reduction

The Future of Large Truck Design

• Special Vehicles Policies
• Fuel costs, emissions, congestion and safety will
  likely create a demand for a new vehicle category

Study Area

• Lewis County northerly to Canadian border.
• Interstate 5
• Mainline railroads
• Major intercity energy facilities
• Operate on separate rights-of-way

21
Maximum Corridor ROW Width
22
Truck Component

• May be enough long-haul truck volume to support
  southern segment from Seattle to Oregon, but
  would require some public funding
• To be financially feasible, a two-lane
  truck-toll highway south of Seattle would need to
  divert 50 of long-haul trucks from I-5. Trucks
  could pay up to a 60 toll (about 0.60/mile)

23
Added benefits of safety and cleaner environment

Status of Ongoing Truck-Only Initiatives

• I-81 Truck Corridor - Fred Altizer, Virginia DOT
• I-35 in Texas Planning for a Franchise
  Agreement
• I-10 to Port of Gulfport State legislation
  required
• I-70 in MO - Determining financial feasibility
• I-710 and SR 60 in SoCal Planning/feasibility
