Problem 1 Many commercial transportation planning software provide a module called as Select Link Analysis. The purpose of the analysis is to determine the origin and destination of all trips on a given link in a highway network. More specifically, the analysis attempts to identify where traffic flow on a particular link comes from and heads to. Such analysis is particularly useful in the justification of new highway corridors, estimation of impact fees, calibration and validation of base year trip distribution and assignment models etc. To perform such an analysis, these software packages utilize path flows generated from various algorithms to directly estimate the OD-specific link flow. Briefly comment on the above "Select Link Analysis" procedure. (Hint: recall the uniqueness of link flow and path flow discussed in class).
