The principle objective of this research was to develop an integrated model to represent the interrelationships between land use and transportation, subject to the requirements of the ISTEA of 1991 and the CAAA of 1990. The integrated model includes two major parts: a land-use allocation module and a travel demand module. An interface module has also been built to transform data between these two modules. The land-use allocation module consists of a residential location model, an employment location model, a land use potential model, and a land consumption model. One unique feature of the residential and employment location models is that they simultaneously estimate passenger movement by work-to-home, home-to-shop and work-to-shop trips between zones before entering the travel demand module. Then the TRANPLAN-based travel demand module carries trip generation and trip distribution stages for estimating home-based school, home-based other, non-home-based, external-internal and external-external trips. The land consumption model, which is significantly different from the LANCON procedure of DRAM/EMPAL, is based on micro-economic theory to simulate the profit-maximizing behavior of housing or landowners over time. The major purpose of the land consumption model is to satisfy the need to reach a balance between demand and supply in the housing market during each time period. The land consumption model is also influenced by Anas’s work in CATLAS, which did not deal with employment location, but simultaneously considers housing location and employment location. The integrated model can be used to evaluate land use policies and transportation policies. Tests run for the Lafayette area have demonstrated that the model can be used to quantify positive and negative effects of long range transportation and land use plans. The final report has two parts. Part I is the technical report that describes how the Indiana Transportation Land Use Modeling System (ITLUMS) was developed. Part II is a separate user’s guide, which describes the FORTRAN programs that make up ITLUMS, the sequence in which the programs must be run, and the format of the input files needed by the ITLUMS programs.
