Transportation is important because of…
Positive impacts: 10% of GDP is transportation1/4 of USA workers are on either transportation or logisticsThe most common profession among males is Truck Driver
Negative impacts:Consumes: 28.5% of energy and 67.9% of petroleumProduces: 54% of carbon monoxide, 36% of nitrogen oxide,
22% of volatile organic compounds, 1.4% sulfure dioxide
Overcoming global warming, achieving a sustainable economy, and enhancing economic competitiveness requires efficient transportation systems
Ironically, we have overlooked the important role that freight transportation could play…Why??

The Efficiency Paradox
William S. Jevons’ “The Coal Question” (1865) concluded:If demand is (long-term)
elastic, lower prices increase consumption
We need a holistic approach to energy efficiency…
Technology is part of the solution, not the solution
![Page 4: Sustainable and Smart Urban Freight Transport 1 José Holguín-Veras, William H. Hart Professor Director of the Volvo Research and Educational Foundations’](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649ddc5503460f94ad34be/html5/thumbnails/4.jpg)
Key components of a holistic approach
Behavior modificationWe (users, consumers, businesses, etc.) have to
change the way in which we do thingsResearch helps understand how best to accomplish
this
Technologies:Needed to reduce the consumption rates, mitigate/
remediate the damage produced by economic activity, manage the use of resources, etc.
Redesign the economy and urban environmentsSustainability (or lack of) is a design problem

Our work touches these three key components

A science mysteryA political thrillerA melodramaA comedyA Greek tragedyA good drama with a happy ending…

The experience with time of day pricing
Theory and empirical evidence agree that cordon time of day pricing are of limited effectiveness in moving urban delivery traffic to the off hours
2001 Port Authority of New York and New Jersey Time of Day Pricing Initiative20.2% of carriers changed behavior, though mostly by
increasing productivity (not by reducing facility usage) Only 9.0% of the sample increased rates, increases
were relatively small, about 15%69.8% of the carriers that did not change behavior
indicated it was due to “customer requirements” Almost no change in facility use
The same was found in London

The decision about delivery time
Is made jointly between receivers and carriers40% receivers, 38% receivers+carriers, 22% carriers
Let’s take a look at the payoff matrix The first sign represents the impact on carrier and
the second the impact on receiver

(These are non-feasible solutions)
(This is the solution preferred by most carriers)
(This is the solution preferred by most receivers)
The fact that more than 90% of deliveries are made in the day hours clearly show who has the power…
![Page 15: Sustainable and Smart Urban Freight Transport 1 José Holguín-Veras, William H. Hart Professor Director of the Volvo Research and Educational Foundations’](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649ddc5503460f94ad34be/html5/thumbnails/15.jpg)
There is a market failure
Markets typically find the most efficient outcome When they do not, there is a market failure
rationale for public sector intervention Off-hour deliveries are beneficial to Society
(+)Huge environmental impacts due to less pollution(+)Carriers / Regular hour travelers (cars, buses, trucks) benefit(-)Increased noise at night could be easily mitigated (-)However, receivers accrue additional costs
The market failure: carrier savings are not large enough to compensate for the receiver costs
The solution is to either: Compensate the receivers for additional costs, or Develop technologies/systems to allow receivers to do OHD at
lower costs (so that compensation could work)

Pilot Test
Initial efforts delayed by Wall Street collapse, skepticism on the part of the industry…initially a huge challenge because of lack of precedents
Original plan: Sysco and Whole FoodsFoot Locker/New Deal Logistics asked to join testThree separate stages to accommodate them:
Foot Locker (10 stores)/NDL (Oct. 2 -Nov.14, 2009)Whole Foods (four stores) (Dec. 28, 2009-Jan. 31, 2010)Sysco (twenty one stores) (Dec. 21, 2009-Jan. 23, 2010)
About 35 receivers, 20 trucks/vendorsHalf doing staffed OHDHalf doing unassisted OHD

After the end of the pilot
All of the receivers doing staffed OHD reverted back to the regular hours
Almost all the receivers doing unassisted OHD remained in the off-hoursThe reason: reliability of OHD“Our locations will continue to receive ‘night drops’
even though this program has ended as our managers now favor the dependability of night drops vs. late day time deliveries. Thanks again for the program.” Nick Kenner, Managing Partner, Just Salad LLC

The Economic Bottom Line
![Page 27: Sustainable and Smart Urban Freight Transport 1 José Holguín-Veras, William H. Hart Professor Director of the Volvo Research and Educational Foundations’](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649ddc5503460f94ad34be/html5/thumbnails/27.jpg)
Economic Impacts
Implementing various forms of off-hour delivery policies in Manhattan leads to:Travel time savings to all highway users of about 3-5
minutes per tripTravel time savings to carriers that switch to the off-
hours of about 48 minutes per delivery tourSavings in service times (per tour) could be in the
range of 1-3 hours
Depending on the extent of the policies, economic savings are between $100 and $200 million/year in travel time savings and pollution reduction

The Impacts of the Project…
NYC adopted off-hour deliveries as part of its sustainability strategy!
![Page 32: Sustainable and Smart Urban Freight Transport 1 José Holguín-Veras, William H. Hart Professor Director of the Volvo Research and Educational Foundations’](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649ddc5503460f94ad34be/html5/thumbnails/32.jpg)
The Impacts of the Project…
In June 2012 the Federal Highway Administration (FHWA) and Environmental Protection Agency (EPA) issued $450,000 in grants for small to medium size cities to implement off-hours goods movement /delivery programs based on the NYC pilot
Numerous cities are considering off-hour delivery programs: Boston, Washington, Atlanta, etc.

Ongoing work
USDOT/RITA provided funds for a larger implemen-tation project focusing on:Unassisted deliveries:
Technologies/systems that enable OHD without the need for staff of the receiving business would produce the same benefits as regular OHD, at minimal cost
To address the liability concerns of receiversLarge Traffic Generators:
Large buildings/establishments generate hundreds of truck trips per day
About 80 such buildings 4% of the truck traffic Adding large establishments 8% of truck traffic
They could implement OHD very cost effectively and without inconveniencing the receivers
![Page 36: Sustainable and Smart Urban Freight Transport 1 José Holguín-Veras, William H. Hart Professor Director of the Volvo Research and Educational Foundations’](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649ddc5503460f94ad34be/html5/thumbnails/36.jpg)
Chief conclusions
Removing the constraints imposed by receivers (either by providing financial incentives, or using un-assisted OHDs) works as it isMore effective than freight road pricingA truly win-win-win-win-win policy:
Benefits regular hours travelersBenefits the environment, improves quality of lifeBenefits the business community, enhances economyNoise impacts could be easily mitigated electric
trucks, low-noise truck technologies/practicesBenefits participants in OHD
Political appeal, implementable as a voluntary program
