Synthesis of Information Related to Highway Practices. Topic 48-06. Integrated Transportation and Land Use Models

In recent years, the fundamental and critical connection between land use and transportation has received increased attention. In some cases, legislation has been adopted (e.g. California SB 375 (2008), Oregon SB 1059 (2010)), that provides further impetus to consider land-use and transportation together. There is an increasing number of integrated transportation and land use models that seek to analyze the interaction between transportation and land-use. However, there is not a single source providing critically needed information for departments of transportation (DOTs) and metropolitan planning organizations (MPOs) about these models. This study will frame analytic needs to support planning, policy, and investment decisions at varying levels of spatial and temporal representation. The study will identify appropriate methods and levels of integration for decision making. A growing number of different techniques, methods and models have been developed over the past fifty years with the aim of integrating transportation and land-use modeling. These tools differ considerably in their complexity, and requirements for data, expertise, and resources. They range from relatively simple sketch-based approaches to complex behavioral urban models. Each of these tools has different appropriate uses, and each differs in the extent to which transportation-land-use interactions are captured. At the same time, transportation models range from activity based, dynamic assignment to trip based, static assignment models, and combinations thereof. This is a study of the interaction between land use and transportation models, ranging from sequential, loosely-coupled to tightly integrated models with feed-backs. The work will summarize and complement existing theoretical discussions of integrated models. The emphasis of this study is documentation of how practitioners have employed integrated models to analyze planning, policy and investment decisions. As well, the study will identify gaps in knowledge and needed research. The objective of this project is to develop a synthesis of integrated transportation and land-use models for use by planning agencies with varying resource levels (DOTs, MPOs, etc.). The project will result in a document that allows planning agencies to identify the type of integrated model that fits their needs. Information will be gathered by review of international literature, a brief screening survey to determine which U.S. and Canadian agencies are using integrated transportation and land use modes. This survey will be sent to state DOTs, American Association of State Highway and Transportation Officials, Standard Committee on Planning (AASHTO SCOP), Canadian Ministries of Transportation (MOTs), and Association of Metropolitan Planning Organizations/National Association of Regional Councils (AMPO/NARC) members. Interviews will then be conducted with agencies known to have varying levels of integration with their transportation and land use models that are in use. The report will include 5 - 10 case examples that illustrate differing approaches to use of integrated models. The consultant will identify agencies to be interviewed; this list will be reviewed by the topic panel. Information to be gathered and summarized includes, but is not limited to: (1) Definition of integrated models and levels of model integration; (2) Types of policy, planning, and investment decisions that might be informed by the use of integrated models, appropriate model types, and level of integration; (3) Different approaches that are available and that have been applied to integrate the planning of transportation and land-use; (4) Classification of the approaches in terms of capabilities, theoretical approaches and requirements (data, computational and human resource, expertise); (a) Feedback mechanisms, including accessibility and impedance (e.g. times and costs); and (b) Summarizing the key benefits of the various approaches. (5) For each class, there will be examples of the use of these approaches. These will include: (a) the institutional context (planning agency); (b) to what purpose the approach was adopted; (c) what the model results were: (i) types of policies evaluated; (ii) comparisons that were possible; (iii) forecasts that were generated; (iv) how the model results were used in planning and decision making- including value added to the process; (v) the value of enhance integration; (vi) what resources and data were needed and the costs; (vii) the degree to which the example was considered successful by the stakeholders, and lessons learned; and (viii) validation of model outputs for current and future years. (6) Gaps in knowledge and practice, and future research directions.
