FHWA Makes Modeling Tool Available to Help Keep Freight Moving in Hurricane Season
WASHINGTON - During the coming hurricane season, states will have greater access to a Federal Highway Administration (FHWA) modeling tool that can help them prepare for freight traffic shifts resulting from major road closures after natural disasters, FHWA Administrator Victor Mendez announced today.
The Freight Analysis Framework (FAF) modeling tool can show how truck traffic will shift regionally or nationally in response to major road closures. The tool works by removing the closed or damaged highway from the networks, and recommending alternate available routes.
Mendez is encouraging states to take advantage of FAF, posted on the FHWA web site at http://ops.fhwa.dot.gov/freight/freight_analysis/fd/index.htm. FHWA has refined and updated FAF over the years to make it more widely available.
"We expect this tool to be critical in the coming months in helping states know where freight traffic is likely to increase if a hurricane closes major roads," said FHWA Administrator Mendez. "It can help states plan for alternatives when major freight routes are closed, helping businesses continue delivering their products following a natural disaster."
During the recent flooding that affected a major freight route, I-40 in Arkansas, the FHWA used FAF to project potential freight movement changes that affected six Southeast states and analyzed where long-haul freight trucks might detour during the I-40 closure.
Knowing the changes in regional freight travel patterns in times of crisis can allow states to set up detours, prepare alternative routes to handle more traffic, and adjust signals and message signs. It can help ensure traffic continues to flow smoothly and safely for people on the highways.
FAF is the most comprehensive publicly available dataset of freight movement. It includes data on the amount and types of goods that move across land, sea and air between large metropolitan areas, states and regions. It is designed to provide comprehensive information on national level freight flows across the nation's transportation network.
