Service Reliability Impacts Of Computer-Aided Dispatching And Automatic Vehicle Location Technology: A Tri-Met Case Study, James G. Strathman, Kenneth Dueker, Thomas J. Kimpel, Rick Gerhart, Ken Turner, Pete Turner, Steve Callas, David Griffin

Center for Urban Studies Publications and Reports

This paper presents findings on initial changes in service reliability following Tri-Met’s deployment of a new bus dispatching system using automatic vehicle location and automatic passenger counter technology. Changes in on-time performance, headway variation, run time variation, and run times were determined with respect to pre-deployment levels. Changes in headway variation and run times were also used to estimate the initial benefits of the new system with respect to operating costs, passenger waiting, and passenger travel time.

California Vehicle License Fees: Incidence And Equity, Jennifer Dill, Todd Mitchel Goldman, Martin Wachs

Urban Studies and Planning Faculty Publications and Presentations

Most states tax the value of residents' motor vehicles. In recent political debates over the future of these levies, the relative effects of these taxes on different socioeconomic groups have been a prominent question. By linking data from the Nationwide Personal Transportation Survey with estimates of vehicle values from consumer vehicle pricing guides, the socioeconomic and demographic incidence of California's Vehicle License Fee is examined. After the effects of state and federal income tax deductions are taken into account, the fee is found to be as regressive as the state's sales tax.

This report provides a school Enrollment Forecast, including background demographic information and analysis, for the Eagle Point School District (Jackson County School District #9). Several factors that are likely to affect the District’s enrollment between 2000 and 2010 are considered and the geographical areas within the District (the cities of Eagle Point and Shady Cove, the unincorporated urban area of White City, and the rural unincorporated area) are examined. To account for different probabilities of demographic events, three scenarios of population, housing, and enrollment changes were developed. Forecasts are made for the total District, by grade level, for the years …

Income Distribution, City Size, And The Role Of Public Transportation, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This article presents an income inequality analysis for all 1990 U.S. metropolitan statistical areas (MSAs). The analysis is concerned with whether public transportation has a detectable influence on levels of urban income equality. Because public transportation systems are generally designed to link residences with employment locations, higher levels of transit service provision, all other factors being equal, should be associated with higher employment rates and more uniform distributions of economic gains. The research presented here was influenced by an analysis originally performed by Haworth, Long, and Rasmussen (1978). Along with there study, few analyses have tried to evaluate policies that …

Center for Urban Studies Publications and Reports

This paper presents findings on initial changes in service reliability following Tri-Met’s deployment of a new bus dispatching system using automatic vehicle location and automatic passenger counter technology. Changes in on-time performance, headway variation, run time variation, and run times were determined with respect to pre-deployment levels. Changes in headway variation and run times were also used to estimate the initial benefits of the new system with respect to operating costs, passenger waiting, and passenger travel time.

Risk-Based Monitoring: A Model And Application To Fda’S Imported Food Monitoring Program, Sheila A. Martin, Nancy Dean Beaulieu, Richard Williams

Institute of Portland Metropolitan Studies Publications

Regulatory agencies intervene in risky situations by outlawing practices that impose risks on society or by proscribing practices that reduce risk. Because public resources for enforcing regulation are limited, public policy has recently emphasized maximizing the benefit from enforcement by considering the risk reduction achievable from each intervention. This emphasis requires a shift of resources to monitoring situations in which regulatory violations are most likely, their welfare effects are most serious, and their detection is probable and relatively inexpensive. This article is a risk-based monitoring model applied to the Food and Drug Administration's (FDA) import monitoring program. Although some components …

Pedestrian Infrastructure Improvements: Effects On Transit Use And Perceptions Of The Pedestrian Environment In Portland's Roseway Neighborhood, James G. Strathman, Kenneth Dueker, Peter Mye, Joyce A. Felton

Center for Urban Studies Publications and Reports

Over the past two years the Pedestrian Transportation (PTP) of the City of Portland has been engaged in a project to encourage walking and transit use through targeted infrastructure improvements. These improvements are intended to enhance pedestrian access to transit service by aiding street crossing and providing more amenities at bus stops. Other improvements include landscaping, sidewalks, curb extensions and ramps, and improved street lighting. One of the basic assumptions of this project is that the pedestrian environment is related to transportation choices. This report explores that assumption.

Orbit: The Oregon Road Base Information Team Draft Summary Report Ii, Paul Bender, Mark Bosworth, Kenneth Dueker

Center for Urban Studies Publications and Reports

Data sharing among organizations has the potential to 1) decrease long-term costs of obtaining and maintaining data and 2) to facilitate data consistency and accuracy. Consistency includes both completeness and currency, while accuracy includes positional and relative accuracy of transportation features and their attributes, i.e. any data element related to roads or other transportation infrastructure.

ORBIT, the Oregon Road Base Information Team, is an ongoing effort to create an accessible and comprehensive GIS transportation base for use by public and private agencies with shared stewardship through stakeholder partnerships and standards. ORBIT is occurring concurrently with an effort at the national …

An Analysis Of Neighborhood Vitality: The Role Of Local Civic Organizations, Irina V. Sharkova, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This paper addresses the issue of neighborhood vitality from the perspective of social capital building. Numerous studies have shown that social capital - a complex of networks, norms, and social trust that promotes citizens involvement in local affairs - is crucial for the continuous well-being of communities. Among many political, economic, and cultural factors influencing social capital, the spatial dimension is most often overlooked. Yet the accessibility of places promoting social interactions and interpersonal communication between local residents should have a direct effect on the vitality of a neighborhood. Among these civic places are formal institutions - churches and locally …

This is the final report of the Lloyd District transportation management program and the subsequent survey.

During the one year that had elapsed between the implementation of the Lloyd District transportation and management programs and the survey information collected in this study, the drive alone mode for the trip to work by employees in the Lloyd District had decreased by 7 percent. For the District as a whole, the drive alone commute share is about 56 percent. These are remarkable achievements.

Gis-T Data Sharing Issues, Kenneth Dueker, J. Allison Butler

Center for Urban Studies Publications and Reports

The purpose of this paper is to develop a framework and principles for sharing of transportation data. The framework is intended to clarify roles of the various participants and the principles are intended to provide guidance for the participants. Both the framework and the principles are based on a GIS-T data model that defines relations among transportation data elements. (See Dueker and Butler (1998) for a detailed description of the data model. A simplified version is provided in the next section.) The data model guards against ambiguities and provides a basis for the development of the framework and principles for …

Benefit Analysis Of Igbt Power Device Simulation Modeling, Michael P. Gallaher, Sheila A. Martin

Interoperability Cost Analysis Of The U.S. Automotive Supply Chain, Smita B. Brunnermeier, Sheila A. Martin

Institute of Portland Metropolitan Studies Publications

The objective of this study was to assess the costs of imperfect interoperability to the U.S. automotive supply chain and to describe the sources of these costs. By understanding the sources and magnitude of inefficiencies caused by interoperability problems, NIST can better determine the potential impact of its programs and focus them to maximize program effectiveness. This study estimates that imperfect interoperability imposes at least $1 billion per year on the members of the U.S. automotive supply chain. By far, the greatest component of these costs is the resources devoted to repairing or reentering data files that are not usable …

Holgate Lake Study: An Examination Of The Issues Associated With Groundwater Flooding, John J. Lynch Jr., Heidi A. Mader, Mark Mccann

Master of Urban and Regional Planning Workshop Projects

This project examines Holgate Lake. Despite its natural hazard characteristics, the Holgate Lake area has not been immune to development pressure. Holgate Lake is an intermittent water body that forms when groundwater levels rise. Historical accounts show that the lake has formed at many different times in the last century. Because the lake fluctuates with the groundwater level, it is not necessarily present from year to year. As the area has developed, more and more people built in the location of the natural lakebed when the water was not present. When the lake level returned in the 1960's flooding of …

Is There Still A Need For The Special Assessment Program Within Oregon's Current Land-Use System?, David R. Brooks

Center for Urban Studies Publications and Reports

Based on the research completed to date regarding the various components of the Oregon farmland preservation program, one question begs to be asked: "Is there still a need for the Special Assessment Program within Oregon's current land use planning system?"

This paper is an attempt to assess the role of the Special Assessment Program in the context of the overall land use planning system in Oregon. It is my contention that the Special Assessment Program no longer plays a meaningful role in the movement to preserve land in the rural areas of the state. Also, it may actually have perverse …

Light Rail Transit Impacts In Portland: The First Ten Years, Kenneth Dueker, Martha J. Bianco

Center for Urban Studies Publications and Reports

This paper examines how the first decade of light rail transit (LRT) in the Portland region has affected auto ownership, mode share, density, and property values. The empirical analysis provides evidence that light rail has had some positive effect of rail on single-family property values, transit use, and slower growth of two-plus car households in the outer part of the LRT corridor as compared to an outer part of a parallel bus corridor. These effects may be the result of households self-selecting to make housing location decisions where LRT is located, rather than current households changing mode.

This assessment of …
