The University of Denver’s remote sensing system for vehicle exhaust has been successfully adapted to the measurement of vehicle emissions in a tunnel environment. Two studies conducted at the Fort McHenry Tunnel in Baltimore, MD and the Tuscarora Mountain Tunnel located west of Harrisburg, PA on the Pennsylvania Turnpike are described. The difficulties associated with remote sensing in a tunnel environment have led to a number of improvements in the remote sensing technology. The successful use of a prototype periscope system is described and evaluated along with the first-time measurements of dual lane traffic.
