The past decade has seen substantial growth in U.S. (domestic) energy development.
Much of it is due to a combination of horizontal drilling and hydrofracturing (‘fracking’) in shale formations that hold oil and gas.
Some states also have extensive wind energy developments.

Energy Development (EDev) and roadway traffic1
• EDev is often concentrated in rural/agricultural areas • Local infrastructure & networks designed for low traffic volumes • Can also affect urban areas
• EDev is associated with rapid increases in population
• EDev affects roadway traffic and driver characteristics: • Specific types of vehicles (heavy trucks) and
drivers (younger, male)
• EDev activity is difficult to predict

EDev and roadway traffic
• EDev can require over 1,000 truck trips to develop and fracture a single well: • Site and well installations
• Large/heavy construction and rig equipment • Access roads
• Well operations - millions of gallons of water/chemical/sand mixture per well • Freshwater input • Saltwater output
• Resource extraction – crude oil trucks • Additional truck trips for refracturing the well
• Timing?? • Equivalent to millions of passenger cars

Roads which previously had less than tens or hundreds
of trucks per day now have hundreds or thousands
of trucks per day

Commercial vehicle violations
Examples from Pennsylvania State Police
• Timeperiod: April 1 to June 7, 2010 Roadside inspections: 400 industry trucks
56% driver or vehicle placed out of service for serious safety violations (Cook, 2010)
• Timeperiod: January 2010 to June 2011 Roadside inspections: 5,800 industry trucks
13,000 driver and vehicle safety [combined] violations, including 2,800 serious safety violations that placed
the driver or truck out of service (Schmitz, 2011)

How are eight other state DOTs addressing safety issues?
• Prevention • Increasing weight/load restrictions for roads and bridges
(some states) • Educating industry and public (some states)
• Partnering • Bonding/road use maintenance agreements (some states) • Commercial vehicle and traffic enforcement (all states) • Industry-agency collaborations/coalitions (some states)
• Maintenance and construction (all states) • Resurfacing and rebuilding • Widening roads and shoulders • Adding turning lanes

DOT challenges in addressing energy development impacts
• Informational • Data on traffic, future developments not shared by industry • EDev partners may not understand seasonal road impacts • Changes in markets, locations difficult to predict
• Spatial – scale of impact may be a few counties, or entire state
• Resources – Financial • Revenue sources • Transportation appropriations
• Resources – Personnel • Labor shortages/ability to pay
• Organizational • Headquarters/District • Proactive/Reactive

Summary
• EDev can have substantial benefits for communities, landowners, states, and industry partners
• EDev can also result in transportation system impacts, including on traffic safety
• Extremely complex relationships between industry, market, regulatory, development, and infrastructure, and demographics
• Other states/DOTs vary in how they are addressing EDev impacts on transportation systems
• Planning for growth and associated impacts on local communities and states can be challenging, but is very important
