  7. Abstract:
  8. There is a two-way relationship between land use and transportation. So each of them can be used to manage and control the other one. Land use can be Auto-Oriented, or Transit-Oriented. Auto-Oriented Development leads to urban sprawl, causing longer trips and increasing use of private cars. Problems related to this type of development appeared by the end of the 20th century. On the other hand, Transit-Oriented Development may lead to higher density areas, and higher transit use, providing better space for pedestrians and cyclists, as well as increasing environmental pollutions. Land use-transportation relationship hs been the subject of many recent studies. One of the previous models investigates land use and transportation developments to reduce the living cost, in which transit development is only aggregately considered by virtual links. In this study, we improve this model by using optimal strategy in transit demand assignment. We propose a bi-level model in which the upper level is a land use model and the lower level is a transportation model. The land use employes the Garin-Lowry model, and the transportation model includes auto traffic assignment problem and transit assignment sub-problems. The bilevel model can evaluate transit development role in land use and vice versa. Result reveal that well-matched development of land use and transit facilities increases the benefits of independent development of each of them. This effect is more clear in high density areas. Although bus transit development decreses public living cost, it could not show as effective as subway within a transit oriented development framework
