TRB’s Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 16: Safety Impacts of Speed Limiter Device Installations on Commercial Trucks and Buses explores issues associated with speed limiters including measurable safety impacts, metrics, and degree of benefit. Speed limiters, also described as speed governors, are devices that interact with a truck engine to only permit the attainment of a pre-programmed speed.
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.
