The highway investment analysis package (HIAP), a computerized evaluation and investment programming model, has been developed for the Federal Highway Administration to aid state, regional, and local organizations in making the best use of limited highway funds. HIAP uses microeconomic theory to analyze individual roadway sections and limited networks of sections specified by their physical, traffic, and operational characteristics. Estimates of both highway user (i.e., vehicle operating costs, travel times, and accidents) and nonuser(i.e., noise levels and air pollutant emissions) impacts are produced. HIAP develops multiperiod investment programs by selecting those improvements that maximize either user benefits or one of several accident reduction measures. The selection process permits consideration of a broad range of funding constraints, which may be tailored to the specific needs of individual organizations. Based on marginal analysis, the process allows consideration of multiple alternatives and staged improvements at each analysis site. Great flexibility in the contant and format of input data is afforded the analyst. Furthermore, HIAP includes a transformation program that allows the analysis of data already available in the format used for the 1970 to 1990 highway needs study.
