This paper defines a range of new highway capacity needs and associated capital funding required to maintain 1985 levels of service on non-local highway systems in the nation`s urban areas through the year 2005, under alternative travel growth scenarios and severity of land use/transportation management strategies. The analysis procedure, which has been computerized on a Lotus 1-2-3 spreadsheet, estimates the number of lane miles which would be required to maintain 1985 average intensities of use (i.e., vehicles miles per lane mile) in the peak hour. These intensities of use are specified by functional class, location within the urban area (i.e., core, suburbs or fringe) and urban area size. The analysis results indicate that even under a relatively low annual rate of growth (2.36% per year) with high levels of land use/transportation management strategies, about 107,000 lane miles of new capacity will be needed, amounting to a 22 percent increase above the 494,300 existing lane miles within expanded urbanized area boundaries. This is estimated to cost $375 billion in 1988 dollars or about 1.7 cents per vehicle mile of travel. 12 refs.
