A Comparison Of Four Work Trip Distribution Models

A study was made of the relative effectiveness of four work trip distribution methods as applied to a rapidly growing industrial complex in and near Lexington, Kentucky. The distribution procedures tested were the Electrostatic Model, Gravity Model, Competing Opportunities Model, and Multiple Regression Model. Each was evaluated by comparing the distributions computed from the model with the actual interchange of industrial work trips obtained from a large-sample origin and destination (O and D) survey. The Multiple Regression Model, derived from the O and D data, yielded the most accurate distribution patterns. Of the three theoretical procedures, the Gravity Model proved most effective.
