Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning Jul 2014

Accessibility-Based Transportation Planning: Literature And Applications For Shrinking Cities, Joanna Ganning

TREC Final Reports

For 15 years, scholars have claimed that accessibility-based transportation planning was at the brink of becoming a new paradigm, and yet this hope remains unrealized. Its implementation may lag due to vague definitions when compared to mobility, or because those who would benefit from accessibility-based planning lack political power to rally its support. Possibly, the lag in implementation reflects the missing linkages between theory and application for many contexts. This literature review synthesizes knowledge regarding the applications for accessibility-based transportation planning for shrinking cities along the themes of environmental, social, and economic sustainability. While residents in shrinking cities might especially ...

Continuous Data Integration For Land Use And Transportation Planning And Modeling, Liming Wang, Kihong Kim Jun 2014

Continuous Data Integration For Land Use And Transportation Planning And Modeling, Liming Wang, Kihong Kim

TREC Final Reports

There is an urgent need for improved models that address the interdependencies between land use and transportation, and considerable new work is underway to develop such models in Oregon and elsewhere. These models and planning practices to integrate land use into the process, however, require the integration of massive amounts of land use data that is messy and incomplete. There have been considerable advances in the treatment of such data problems in other domains, drawing on data mining and machine-learning techniques to address issues in various domains. To date, however, little systematic effort has applied these technological advances to the ...


Transit Planning Practice In The Age Of Transit-Oriented Development, Ian Carlton Apr 2014

Transit Planning Practice In The Age Of Transit-Oriented Development, Ian Carlton

TREC Friday Seminar Series

Transit serves as backbone infrastructure for many regional and local visions for sustainable urban development. Also, many modern policies predicate transit funding on the potential for transit-oriented development (TOD) near proposed infrastructure investments. However, little research has examined how TOD considerations have informed transit planning. This presentation discusses the results of recent dissertation research that fills this gap. Through multiple transit project case studies and interviews with nearly 100 transit planning professionals, this research categorized how transit projects across 19 U.S. regions were designed to foster TOD and how transit planning professionals identified TOD opportunities as projects were planned ...

Data-Driven Illustrations For Climate Smart Communities Scenarios, Nancy Yen-Wen Cheng, Kim Ellis, Molly Vogt, Clint Chiavarini, Justin Houk, Brian Lockyear, Boyce Postma, Peggy Morell

TREC Final Reports

Public investment in transit and streetscape improvements can encourage private development, and subsequently increase transit ridership and reduce pollution. Portland, OR’s Metro regional government has developed investment scenarios designed to reduce light vehicle carbon emissions. Adopting a regional scenario requires public review and consultation with local governments who will implement the comprehensive plans and land-use regulations. Decision makers and residents need to understand potential benefits: ways in which targeted investment could generate more livable urban spaces while reducing greenhouse gases. Illustrations can show how the investments could shape the pedestrian experience through trees, street furniture, buildings, open spaces, etc ...

Regional Transportation And Land Use Decision Making In Metropolitan Regions: Findings From Four Case Studies, Richard D. Margerum, Susan Brody, Robert Parker, Gail Mcewen, Terry Moore

TREC Final Reports

Throughout the United States, metropolitan regions face increasingly complex issues related to transportation and land use. The diffuse nature of decision making creates a need to better coordinate land use and transportation to address issues such as: congestion, infrastructure costs, and greenhouse gas emissions. Key players in this decision making are regional metropolitan planning organizations (MPOs) with transportation planning authority, regional planning responsibilities, and in some cases regional land use planning authority. The goal of this study was to describe and assess efforts by regional agencies to coordinate land use and transportation. Policies and processes in four key topic areas ...

Green And Economic Fleet Replacement Modeling: Part I, David S. Kim, Miguel A. Figliozzi, J. David Porter

TREC Final Reports

The purpose of this study was to gain a better understanding of how equipment replacement decisions are supported with data collection and quantitative models at state DOTs, and to determine if models found in the research literature offer any better decision support when applied to realistic fleet usage and cost data. This study also addressed the current state of equipment replacement at state DOTs with respect to using measurable “green” criteria in replacement decisions, and the development of new quantitative replacement models utilizing such criteria. The responses from 25 state DOTs indicates that there is little consistency in the criteria ...

Ibpi: Bicycle And Pedestrian Education Program, Jennifer Dill, Lynn Weigand, Karen Dixon

Urban Studies and Planning Faculty Publications and Presentations

Since the 1990s, the amount of attention and funding for bicycle and pedestrian infrastructure has increased significantly. This, combined with the role of transportation in public health and environmental concerns, has raised expectations for engineering and planning practitioners to possess more knowledge and skills related to pedestrian and bicycle planning and design. This demand requires more education around these topics but university curriculum doesn?t reflect these important shifts in the field. This project was intended to begin addressing the need for more bicycle and pedestrian curriculum in two ways: (1) Determine the existence of and need for courses and ...


Co-Evolution Of Transportation And Land Use: Modeling Historical Dependencies In Land Use And Decision-Making, Lei Zhang, Wei Zu, Mingxin Li Nov 2009

Co-Evolution Of Transportation And Land Use: Modeling Historical Dependencies In Land Use And Decision-Making, Lei Zhang, Wei Zu, Mingxin Li

TREC Final Reports

The interaction between land use and transportation has long been the central issue in urban and regional planning. Models of such interactions provide vital information to support many public policy decisions, such as land supply, infrastructure provision, and growth management. Both the transportation and land use systems exhibit historical dependencies in policy decisions. For instance, the expansion of a roadway today will change travel demand patterns, and make certain other roads more or less likely to be expanded in the future. A specific land supply decision made at one point in time, by changing the relative attractiveness of other areas ...

Travel And Transit Use At Portland Area Transit-Oriented Developments (Tods), Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

In recent years there has been a growing interest in using land use planning to reduce reliance on the automobile long-term, through ideas such as smart growth, New Urbanism, pedestrian pockets, and transit-oriented development (TODs). Many growing regions throughout the United States, are turning to these concepts to address problems of traffic congestion and suburban sprawl. However, the effectiveness of such policies in reducing automobile travel and improving livability is largely unknown. Portland was one of the early adopters and is often pointed to as a model for other regions. The Region's 2040 Growth Concept, adopted by the Metro ...

The Effects Of Roadway Capacity On Peak Narrowing - Evidence From 1995 Npts, Jihong Zhang, Anthony M. Rufolo, Kenneth Dueker, James G. Strathman Jul 2000

The Effects Of Roadway Capacity On Peak Narrowing - Evidence From 1995 Npts, Jihong Zhang, Anthony M. Rufolo, Kenneth Dueker, James G. Strathman

Center for Urban Studies Publications and Reports

Spreading of the peak is one effect of increased peak-period congestion. Due to peak spreading, the travel-time impact of congestion is mitigated for some travelers, but the inconvenience of traveling at a less-preferred time also has a cost. Alternatively, increases in capacity have their impacts on peak-period congestion mitigated by a narrowing of the peak. This reduces the travel-time savings, but it generates a benefit for those traveling closer to their preferred times. This benefit from capacity improvements has largely been ignored, and one reason is the difficulty of quantifying the effect. This paper reports on some crude attempts to ...

Highlights: Accomplishments Of Portland's Downtown Plan, Central City Plan, Albina Community Plan, Outer Southeast Community Plan, Portland (Or.). Bureau Of Planning

Portland Regional Planning History

All four plans were comprehensive. Their scope included transportation, housing, economic development, parks and open space, natural resources, urban design, and land use. Large scale planning efforts had previously focused on a limited set of concerns, such as parking, commercial revitalization, or housing. The Downtown Plan, Central City Plan, Albina Community Plan, and Outer Southeast Community Plan, on the other hand, evaluated, balanced, and integrated the different elements so that each action was taken in light of its effect on others. Extensive citizen involvement shaped the content of these plans and contributed to their success.

Cost Effectiveness Of Articulated Buses When Passenger Time Is Treated As A Cost, Anthony M. Rufolo Aug 1984

Cost Effectiveness Of Articulated Buses When Passenger Time Is Treated As A Cost, Anthony M. Rufolo

Center for Urban Studies Publications and Reports

As the difference between fares and costs has increased over time, transit agencies have searched for ways to cut the cost of service. One method that is now being tried by some transit properties these buses there is a is the use of articulated buses. The larger size of allows one driver to serve more passengers. Thus, trade-off between higher capital costs for the bus and lower labor costs per passenger mile in operation. Hence, the use of the articulated bus appears to be a move toward greater labor productivity by increasing the capital-intensiveness of transit.

The conclusion that articulated ...
