This study examined the potential emissions and energy impact of increasing the federal gross vehicle weight exemption to more sections of Maine’s interstate highway system. This would allow vehicles that weighed up to 100,00 pounds to frequent these additional parts of the interstate highway. The study evaluated the performance of a 6-axle configuration that operated at 100,000 pounds. Two parallel routes were traveled between Augusta and Brewer, Maine. Two different travel scenarios were developed using a simulation model. Results were computer for a “No Stop” option and an “All Stops” option. The “No Stop” options assumed uninterrupted travel, requiring no deceleration, through all traffic lights. The “All Stops” scenario assumed that the truck decelerated and stopped for 20 seconds, and then resumed the posted speed limit, at each traffic light. Findings are provided for both options.
The American Transportation Research Institute (ATRI) has been engaged in critical transportation studies and operational tests since 1954. ATRI is a 501(c)(3) not-for-profit research organization headquartered in Washington, D.C., with offices in Atlanta, Minneapolis, and Sacramento.
ATRI’s primary mission is to conduct transportation research, with an emphasis on the trucking industry’s essential role in a safe, efficient and viable transportation system. ATRI’s research focus areas include: Congestion and Mobility; Economic Analysis; Safety and Security; Technology and Operations; Environment; and Transportation Infrastructure.
ATRI’s extensive experience covers a broad range of commercial vehicle operations including leadership and/or participation in numerous national freight analyses, technology research initiatives and field operational tests.
ATRI presently manages the U.S. DOT’s Freight Mobility Program, and has provided freight mobility and performance measures technical assistance to 31 state DOTs and 11 of the 15 largest MPOs in the U.S. ATRI has received top research awards from ITS America, TIDA, University of Minnesota and the Institute of Transportation Engineers.
