Abstract:This report documents a research project sponsored by the Alabama Department of Transportation (ALDOT) and conducted by the University of Central Florida (UCF) and the University of Alabama at Birmingham (UAB) to develop a user-friendly, Windows version of MOBILE6 and a Windows carbon monoxide (CO) screening model. Both models were developed for use in Alabama-specific applications by the Environmental Technical Section of ALDOT. The models are intended to improve analytical processes at ALDOT and reduce costs by achieving environmental streamlining goals as encouraged by the Federal Highway Administration. The program Alabama MOBILE6 (AM6) is a user-friendly, yet powerful Windows interface to the EPA program MOBILE6.1/6.2. A number of the inputs to this complex model have been pre-programmed, based on guidance from ALDOT. Input is highly visual and easy to accomplish. The Alabama CO screening model (ALCO) utilizes the Environmental Protection Agency's emission factor model MOBILE6 and dispersion model CAL3QHC. These models are built into the screening model and are invisible to the user. A number of the inputs to these complex models have been pre-programmed, based on guidance from ALDOT. Input is highly visual and easy to accomplish. The authors concluded that ALCO successfully incorporates the state of the practice of intersection screening for the state of Alabama, and recommend that ALDOT adopt this model as soon as possible for use in this aspect of air quality modeling in Alabama. The authors concluded that AM6 successfully runs MOBILE6, and makes it easier for people within the state of Alabama to use MOBILE6, while maintaining the flexibility of the program.
