ESTIMATING THE IMPACTS OF CHANGING HIGHWAY CONDITIONS

A discussion of the Highway Performance Monitoring System (HPMS) is presented. The analytical package is a series of computer models designed to use the annually updated HPMS sample inventory data to estimate needs, determine the relationship between highway investments and highway performance, and assess the benefits and costs associated with various investments. The models express highway performance in terms of sufficiency indexes, vehicle operating costs, fuel consumption, and overall running speed. This system-level planning tool is described and examples of the data output are given. Investment performance curves are presented to illustrate the consequences of different investment levels. Although it is concluded that the current analytical package is useful for assessing the effects of future investments on future system performance, there is a need to bring this package together with economic analyses and econometric forecasting tools to permit economic impact analyses of various sectors of the economy, including highway users and industries. As the predictive ability of the models improves, the ability to estimate the costs and benefits of alternatives will improve. (Author)
