ESTIMATION OF AN ORIGIN-DESTINATION TRIP TABLE BASED ON OBSERVED LINK VOLUMES AND TURNING MOVEMENTS. EXECUTIVE SUMMARY
The objective of the project was to develop a model for estimating an Origin Destination (OD) trip table for highway traffic in small areas based primarily on observed link volumes and turning movements. The major use of the trip table would be as an input to traffic assignment and simulation models for estimation of network flows and performance. The model developed in the project, the LINKOD model, has achieved its stated objective. This represents a significant advance in traffic modelling. Major features include: (1) an existing trip distribution model which has been enhanced to account for the unique attributes of small area OD movements; (2) a technique for correcting an input trip table, so it best reflects observed link volumes, has been implemented. This technique is based on the theory of equilibrium traffic assignment; and (3) the model is driven by a software package which permits efficient applications.
