Preliminary results from an integrated transportation and land use models package.

Results, to date of an effort to integrate a land use model with a transportation network model for the purpose of analyzing the interrelationships of transportation facility development and land development, are described. In the system, which has been developed each model provides input to, and receives feedback from, each other model. With this system it is possible to observe the interrelationships, and in particular the feedbacks, between land use and levels of traffic on the networks.
