Abstract

The objectives of this research were to analyze the rate at which units of traffic service are substituted for increments of land access and to evaluate alternative measures of level of land access. Several four-lane undivided arterials in madison, wisconsin, were selected for study. Each arterial was subdivided into sections approximately 0.2 mile in length. Roadway and land use characteristics were recorded for each section, and the average unit travel time within each section was measured for each direction of travel during five different time periods. Multiple linear regression analysis was then used to express unit travel time as a function of level of land access and other influencing variables. The analysis revealed that, as the number of daily trip ends per mile or the amount of commercial floor area per mile increases, unit travel time also increases, the amount of change being dependent on the time of day. Although quantifying level of land access by a trip generation rate is intuitively more desirable, the commercial floor area measure is more easily determined. The results of the research illustrate the importance of the control of roadside development as a means of preserving the quality of traffic service provided by urban arterials.
