The research team developed a comprehensive Benefit/Cost (B/C) analysis framework to evaluate existing and anticipated intelligent transportation system (ITS) strategies, particularly, adaptive traffic control systems and ramp metering systems, in terms of the triple bottom line (TBL) of sustainability (i.e. social, economic, and environmental impacts). The B/C framework for each ITS category was divided into four main areas: Life Cycle Cost Analysis, Analysis of Benefits through Travel Time Savings, Analysis of Benefits through Reductions in Energy Consumption, and Analysis of Benefits through Safety Enhancements. The life cycle cost analysis of an ITS deployment includes infrastructure costs, incremental costs, and O&M costs. The analysis of benefits through travel time savings was grouped into recurring travel time savings analysis and nonrecurring travel time savings analysis. The analysis of benefits through reductions in energy consumption was conducted using a newly-built microscopic scale top-down approach. Analysis of benefits through safety enhancements was mainly focused on fatal crashes. According to the results, the Benefit/Cost ratio (BCR) for a typical ATCS deployment may range between 6.52 and 13.04; whereas the BCR for a typical ramp metering deployment is expected to be around 6.44. We consider the results obtained from our B/C framework as conservative, which means that BCRs calculated in our study can be lower than specific ATCS and ramp metering deployments around the United States.
