LINKING LAND FORM 1 AND DEVELOPMENT LOCATION TO MULTIMODAL TRAVEL DEMAND: CASE STUDIES OF TRANSPORTATION AND LAND USE STUDIES IN DELAWARE

摘要

The Land Use and Transportation Scenario Analysis and Microsimulation (LUTSAM) application is the result of collaboration between the Delaware Department of Transportation and the State Smart Transportation Initiative at the University of Wisconsin – Madison to develop a transferable process which evaluates the impacts of land form and location on travel demand and measures of effectiveness. The process produces information in a manner easily understood by the public and local officials. LUTSAM provides a bridge between GIS, travel demand modeling and 3-D microsimulation and allows traditional and advanced Traffic Analysis Zone (TAZ) based models to operate at the parcel level. The traditional approach to transportation and land use areawide and corridor studies using existing travel demand models and microsimulation is cumbersome and time-consuming. It is difficult to produce the results needed to evaluate the direct impacts of urban form, land use, and multimodal investments on mobility. This is particularly challenging with existing models since many do not operate at the level of geographic resolution needed. Industry-wide, parcel level modeling has been shown to overcome such shortcomings by providing the appropriate level of detail, along with measures of effectiveness that better quantify these analyses, however most parcel based models have also been developed as advanced models. This has left a gap for studies performed in areas lacking advanced models. This paper showcases the application of this tool for five case studies in Delaware.
