1. A total of 5,000 person-trips are made between a commercial district and a residential area during
the PM peak hour. Commuters have two modes available, including private automobile and a light-
rail transit system. The following utility function was calibrated using data from the study area from
users of these two modes:
U 3D -0. 50T1 — 0. 50T, — 2. 00С
Data summarizing the operational characteristics and costs associated with each mode are provided in
the following table.
