Design a refuse collection route for the suburban development shown in Figure 3-25. Note the large and busy four-lane highway and other features. What criteria should you use to judge the suitability of your route? Justify your route on the basis of these criteria. Assume the following: Collection is required on all streets. The trucks come from town and return to town. There is no median strip on the fourlane highway (left-hand turns are possible). All streets other than the highway are small residential streets. The small bridge has a weight limit less than the weight of the empty collection vehicle.
