Description:
The University of Denver in cooperation with the Desert Research Institute, U.S. EPA, and General Motors Corporation have successfully adapted the University of Denver's remote sensing system for vehicle exhaust to the measurement of vehicles in a tunnel environment. wo studies conducted at Fort McHenry Tunnel in Baltimore, MD and the Tuscarora Mountain Tunnel located west of Harrisburg, PA on the Pennsylvania Turnpike are described. he difficulties associated with remote sensing in a tunnel environment have led to a number of environments in the remote sensing technology. ue to logistics and restrictions on placement of equipment in the Fort McHenry tunnel, a prototype periscope system was employed to optimize the height of the remote sensor's infrared beam path relative to vehicle exhaust plumes. t the Tuscarora Tunnel, first-time measurements of dual lane traffic was conducted using a single source and detector and two cameras for vehicle identification. his precluded the normal practice of directing traffic into a single lane which can alter normal driving patterns.
