land-use zone consists of 2000 single-family homes, 520 apartment units, and 3 hotels with 600 rooms each. Calculate the daily vehicular traffic generated by this zone, using the following equations: ts = 5+ 7.35US, ta = 7+ 6.25Ua = 2 + 12.00n t₁ = where the subscripts s, a, and h refer to homes, apartments, and hotels, respectively, and t and U refer to trips and housing units, respectively. Why is there a significant difference in trip production among the units?

Consider the following data: · Average number of vehicles (overtaking - overtaken) = 1 • Average number of vehicles during trips in opposite direction of traffic flow = 336 · Average journey time when test vehicle is travelling with the stream = 8 min 31 sec. · Average journey time when test vehicle is travelling against the stream = 7 min 24 sec. Average journey time for the above data is min. %3D
32. An industrial park consists of 16 buildings. The corporations in the park are sharing the cost of construction and maintenance for a new first-aid center. Because of the park's layout, distances between buildings are most closely approximated by a rec- tilinear distance measure. Weights for the buildings are determined based on the frequency of accidents. Find the optimal location of the first-aid center to minimize the weighted sum of the rectilinear distances to the 16 buildings.
