• Abstract:
  The GASCAP model was developed to provide a software tool for analysis of the life-cycle GHG ; emissions associated with the construction and maintenance of transportation projects. This phase ; of development included techniques for estimating emissions from induced travel when a project ; involves a capacity expansion; a life-cycle maintenance module based on recommended procedures ; for maintaining a road surface over 50 years; an automated method for inputting construction ; equipment activity associated with selected project types; a method based on the Highway Capacity ; Manual for estimating emissions associated with project staging and the diversion of traffic around a ; worksite; methods for more easily updating emissions factors in the model; and, a variety of ; miscellaneous upgrades to account for SF6 emissions, upstream electricity emissions associated ; with asphalt, and incorporation of additional bid-sheet codes in the materials module. Four case ; studies to demonstrate the models usage were also conducted. These were: a large project case ; study (reconstruction of rt 35 in Ocean County) that demonstrated the full capabilities of the model; a ; smaller project (rt 47 resurfacing in Gloucester County) that focused on different staging options and ; the impact on emissions from traffic; an applied case study conducted in collaboration with NJDOT ; staff in the South Jersey regional office that focused on maintenance activities; and a demonstration ; of the relationship between the embodied fuel cost of a project and the GHG emissions. The ; software and related documentation is available for use on www.gascap.org and users are ; requested t
