Abstract: This study accomplishes two objectives: (1) develops a model to forecast future household travel demands for a given solid waste site in Fairbanks, Alaska and (2) develops precursory techniques to evaluate the likely impacts of this demand on the network of urban roadways. A systematic random survey to determine socioeconomic and trip-making behavior was sent to 2000 (approx. 10%) of total households in the Fairbanks North Star Borough. Evaluation of the 885 returned surveys determined the following household averages: age - 42, family size - 3, annual income - $51,000, garbage bag size - 30 gal., and 1.5 enroute trips per week to dispose of solid waste. A Geographic Information System (GIS) was developed to graphically represent and spatially locate essential information, such as: population and housing density distributions within Bureau of the Census tracts, distance (in seconds) between intersections and average daily traffic counts of the major arterial roadways. To further understand the existing and future impacts of solid waste disposal travel demands, a simulation model of this travel demand is developed. The preliminary model simulates solid waste disposal/collection travel on the major arterial roadways, estimates the utilization of existing and future solid waste sites, and capacity projections and hauling frequencies.
