Explain the flaw in each of these traffic analysis zones (TAZs) (a) TAZ 1 contains dormitories, a research park, and 300 single family detached dwelling units. (b) TAZ 2 straddles an interstate highway, with half of the zone east of the highway and half to the west of the highway. (c) TAZ 3 contains 5,000 people
What will be an ideal response?
(a) The first zone contains multiple land uses—ideally a zone should
predominantly contain a single land use.
(b) The second zone includes a major topographical barrier—the interstate
highway. Ideally zones should not include such barriers.
(c) The third zone is probably too large for analysis (containing more than
1,000 people). That in itself is not a firm rule, but in practice such a zone
could easily contain two major parallel routes which may adversely affect
the traffic assignment process.
