Identification and Assessment [chapter]

Language Impairment and Psychopathology in Infants, Children, and Adolescents  
This paper discusses the use of breakeven analysis as a tool to assess the benefits of Intelligent Transportation Systems at the system level in system-wide sketch planning. The breakeven analysis was developed based on the SCRITS (SCReening for ITS) spreadsheet template and used data from Madison, Wisconsin as a case study. The break-even analysis provided considerable insight about the magnitude of the potential benefits of different ITS programs. It can help identify critical performance

Breakeven analysis coupled with sensitivity analysis can be used to identify and assess ITS projects for deployment in the ITS planning and programming process with limited data. The breakeven analysis can be used to screen, prioritize and select ITS projects among different ITS options. It can also be used to compare ITS project in different geographic locations based on different traffic data and breakeven points. The method is also useful in the identification of data needed for detailed ITS project assessments and evaluations. Such data should include before and after studies of ITS deployments as well as refined cost data and traffic flow estimates. The case study identified the break-even points of several ITS deployment options, including ramp metering, travel information systems, emergency response systems, and commercial vehicle operations under a variety of scenarios. These results can be used to identify and operate ITS projects so that they are likely to have the greatest payoff from their deployment.
