# Presentation: 205908

**A Status on****Large Scale Truck Separation****in the United States**

**Presentation to:**
**FHWA’s Talking Freight Seminar on**
**Truck Separated Lanes/Truck Tolling**
**March 16, 2005**
**Arno Hart**
**Wilbur Smith Associates**

## Various Concepts 

**Grade Separated**

**New Mixed-flow or HOV Lanes**

**Tolled Truck Lanes**

**Truck Climbing Lanes**

**State DOT’s**
**are starting **
**to recognize.......**

**Need for additional freight****capacity on highways**

## National I-10 Freight Corridor

**National I-10 Freight Corridor**

## New freight policy directions....

**Also need policies to ****ACCOMMODATE trucks**

**Truck traffic is expected to grow**

**Despite need for continued ****focus on modal DIVERSION **

**Innovations in highway development**
**Innovations in truck mobility/operations**

** ****Research is on going **
** ****Auto Separated Highway System**

** ****TRUCK PLATOONS**

**Mass****Flow****Concept **

**Focus on****Trucks**

** ****Move in mass**
** ****Like rail and barge**

** ****Propel Trucks thru Bottlenecks**

** ****Door to door**
** ****Run anywhere on the system **

**Maintain their service advantage **

**Separation of trucks can**
**provide additional capacity**

## Impact of Freight on Congestion - 2025

**Without Freight**

**With**
**Freight**

## Candidate

**Candidate**
** ****Selection:**
**3 Principal**
** ****Criteria**

**Daily Truck Volume**

**Volume : Capacity Ratios**

**Total Daily Volume**

**Plus: Service Sensitivity**

##    4 Candidates:

** ****LA-Inland Empire**
** ****Phoenix-Tucson**
** ****Houston West**
** ****Gulf Coast**

**High volumes & v/c’s**

**SELECTION: TRUCK ONLY LANES**

**Developing problems**

**Strong central tendencies**

**Rational start/end points**

## Scenario 3 – Truck-Only Lanes

**Car Speed Improvements**

**Deficient Mileage - Reduction**

**(Impact along affected segments of corridor)**

**Separation offers productivity****gains/cost savings**

## % Work Energy Consumed

**Rolling Resistance 32%**

**Aerodynamic Drag 53%**

**Powertrain & Auxiliary Loads ****	****	****	****15%**

## Daimler-ChryslerPromote Chauffeur

**Link drive train, ****braking & steering**

**Electronic drawbar**

**Fuel Savings For 2****nd**** Vehicle**

**  ****15-21% at 80 km/h**

**Not likely in normal traffic **
**conditions in mixed-use lanes **

## Platooning (Chauffeur-2)(coordinated lane changing, accelerating, braking)

**http://www.chauffeur2.net/final_review/**

## Longer Combination Vehicles

## 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**

**Productivity gains provide****for revenue generation**

## Washington CommerceCorridor Feasibility Study

**DEVELOP A N/S **
**TRANSPORTATION **
**AND ENERGY CORRIDOR**

**WITH A LARGER ****ROLE FOR****THE PRIVATE SECTOR**

**Washington Commerce****Corridor Feasibility Study**

## Study Area

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

## Maximum Corridor ROW Width 

## 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)

**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 phase**
