While <br />roads will eventually deteriorate if simply left unused, most <br />deterioration is associated with use; and the damage caused by <br />vehicles goes up much more than proportionately with size and <br />weight. Hence, costs associated with maintenance are greater for <br />trips made by heavy vehicles. A single large truck can cause as <br />much damage as thousands of automobiles, and the configuration <br />of the truck can affect the amount of damage as wail. If the load is <br />spread over more axles, so there is less weight on each wheel, <br />then the damage is reduced.6 <br />Trash trucks are typically the heaviest vehicles regularly operating <br />on residential (local) streets. Asa result, they are a major <br />contributor to the wear and tear on those streets. While trash <br />trucks also contribute to the wear and tear on collector and arterial <br />streets, those streets are designed to a higher standard and <br />experience significantly more vehicle trips and large truck trips <br />than local streets. As such, the relative impact of a trash truck on <br />collector and arterial streets is significantly less than that on local <br />stree#s. Commercial solid waste collection in the City, however, is <br />provided through an open competition license system, with <br />approximately 10 licensed commercial haulers currently operating <br />in the City. This large number of commercial haulers increases the <br />impact of trash trucks on the City's collector and arterial streets <br />compared to a system in which there are fewer licensed haulers or <br />a single service provider (e.g., a municipal or contracted system). <br />The pavement condition index (PCf) is a common unit of measure <br />used to rate the condition of pavements. The PCI rates pavements <br />on a score of 0 to 100 with a higher value indicating better <br />pavement condition. Rapid deterioration of pavement typically <br />e A.
