Kennedy, 60 Minutes, And Roger Rabbit: Understanding Conspiracy-Theory Explanations Of The Decline Of Urban Mass Transit, Martha J. Bianco Nov 1998

Kennedy, 60 Minutes, And Roger Rabbit: Understanding Conspiracy-Theory Explanations Of The Decline Of Urban Mass Transit, Martha J. Bianco

Center for Urban Studies Publications and Reports

This paper will review the history of the GM Conspiracy Myth, as well as what legal theorists refer to as "the facts in the case." The legal explanation of what really happened goes only so far, though. The whole story about the decline of mass transit in the U.S. is a story about the failure of public policy and about conflict among competing constituencies in the transportation policy process. This paper will very briefly discuss this failure and this conflict and will then conclude with a consideration of - or at least a hypothesis for - the endurance of the GM ...


The Connection Between Public Transit And Employment, Thomas W. Sanchez Nov 1998

The Connection Between Public Transit And Employment, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

Even with a considerable amount of attention being paid to the role of public transportation in addressing inner-city mobility problems, there is very little evidence of the degree to which one affects the other. In other words, little research has specifically focused on how labor participation is impacted by increases in public transportation availability. Research on the spatial mismatch hypothesis has dealt with the relationship between labor participation and the spatial separation of jobs and houses; however, most analyses concentrate on commuting time or distance as a function of auto accessibility. Few, if any, studies have considered the relative impacts ...


The Impact Of Congestion Pricing And Parking Taxes On Spatial Competition, Anthony M. Rufolo, Martha J. Bianco Nov 1998

The Impact Of Congestion Pricing And Parking Taxes On Spatial Competition, Anthony M. Rufolo, Martha J. Bianco

Center for Urban Studies Publications and Reports

Policymakers seeking to reduce reliance on single-occupant automobiles are giving serious consideration to methods to price roads during periods of congest ion and to increase the cost of parking. Such policies are intended to induce increases in carpooling and in the use of mass transit; however, they may have unintended consequences that counteract these goals in the long run. In particular, actual implementation of such policies may create differential price increases that affect the spatial competition for markets between firms located in the central city and those in the suburbs. Analyzing such policies using the spatial competition models of location ...


The Politics Of Implementation: Oregon's Statewide Transportation Planning Rule - What's Been Accomplished, Martha J. Bianco, Sy Adler Nov 1998

The Politics Of Implementation: Oregon's Statewide Transportation Planning Rule - What's Been Accomplished, Martha J. Bianco, Sy Adler

Center for Urban Studies Publications and Reports

This paper is a case study of the evolution of Oregon’s groundbreaking Transportation Planning Rule, from its adoption in 1991, up through present amendments. Our analysis is an assessment of how private- and public-sector investors grapple with the coproduction of the built environment under the constraints of a value system that emanates from the state, shepherded by litigious public interest groups. In this case, this value system is articulated in the Oregon administrative rule known as the Transportation Planning Rule. This Rule emphasizes a reduction in the reliance on automobiles and, among other things, requires a decrease in vehicle ...


Marketing Central City Residence To An Aging Baby Boom: The Transportation Angle, Daphne Spain, Thomas W. Sanchez Nov 1998

Marketing Central City Residence To An Aging Baby Boom: The Transportation Angle, Daphne Spain, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This paper proposes that the aging baby boom will contribute significantly to transportation problems in the future because 1) current land use patterns necessitate dependence on cars; and 2) aging baby boom women will drive more than elderly women do now. Policies that promote central city residence by stressing the transportation advantages of high-density living, therefore, should have particular appeal to baby boom women seeking prolonged independence. Such policies would also serve the interests of localities by reducing traffic congestion, pollution, and further sprawl. We suggest that a combination of direct and indirect housing policies comparable to those that financed ...


The Oregon Dot Slow-Speed Weigh-In--Motion (Swim) Project: Final Report, James G. Strathman Sep 1998

The Oregon Dot Slow-Speed Weigh-In--Motion (Swim) Project: Final Report, James G. Strathman

Center for Urban Studies Publications and Reports

Weigh-in-motion (WIM) systems have provided an effective means of data collection for pavement research and facility design, traffic monitoring, and weight enforcement for over 40 years. In weight enforcement, WIM systems have been increasingly used to screen potentially overweight vehicles. Vehicles that exceed weight limits as measured on a WIM scale are then weighed on a static scale, which is subject to accuracy standards specified by the National Institute of Standards and Technology (1998). The use of WIM for screening purposes reduces queuing at weigh stations, resulting in considerable savings for both truckers and enforcement agencies. To date, however, WIM ...


Analysis Of Assessment Uniformity In Relation To Favorable Mortgage Terms, James G. Strathman Aug 1998

Analysis Of Assessment Uniformity In Relation To Favorable Mortgage Terms, James G. Strathman

Center for Urban Studies Publications and Reports

This paper examines the capitalization effect of mortgages with favorable terms on the coefficient of intra-area dispersion (COD), the statistic commonly used to measure assessment uniformity. Regression analysis using data from the 1982 Census of Governments indicates that as much as one third of the value of the 1981 state-level CODs can be attributed to the capitalization effects of financing rather than assessment performance. Post-1982 improvements in uniformity can be expected in light of the sharp decline in non-standard sources of mortgage credit.


A Gis Methodology For Assessing The Growth Impacts Of Highway Improvements, Thomas W. Sanchez, Kenneth Dueker Jul 1998

A Gis Methodology For Assessing The Growth Impacts Of Highway Improvements, Thomas W. Sanchez, Kenneth Dueker

Center for Urban Studies Publications and Reports

This paper presents a methodology to assess the induced land use effects of state highway improvements on urban development patterns. The methodology is applied to the case study City of Hillsboro, Oregon and illustrates a framework for data management and analysis. A set of temporal land use characteristics and spatial measures are used as predictors of urban development activities resulting from highway accessibility improvements. A multiple regression analysis tests the significance of these variables in predicting rates and locations of urban development. The primary objective of this research is to identify the relationship between capacity increasing highway improvements and changes ...


Automated Bus Dispatching, Operations, Control, And Service Reliability: Baseline Analysis, James G. Strathman, Kenneth Dueker, Thomas J. Kimpel, Rick Gerhart, Ken Turner, Pete Taylor, Steve Callas, David Griffin, Janet Hopper Jul 1998

Automated Bus Dispatching, Operations, Control, And Service Reliability: Baseline Analysis, James G. Strathman, Kenneth Dueker, Thomas J. Kimpel, Rick Gerhart, Ken Turner, Pete Taylor, Steve Callas, David Griffin, Janet Hopper

Center for Urban Studies Publications and Reports

The authors of this report are engaged in a long term project to assess the impacts of Tri-Met's BDS on service reliability and transit use. The framework designed for this assessment focuses on documenting service reliability and passenger activity at three major junctures:

• The pre-operational (baseline) period;

• The initial (passive) period following implementation of the new system, when both drivers and dispatchers have access to schedule adherence information in real time, but before the development and use of operations control practices that exploit the information generated by the system;

• Full implementation, when operations control practices are defined and actively ...


Effects Of Light Rail Transit In Portland: Implications For Transit-Oriented Development Design Concepts, Kenneth Dueker, Martha J. Bianco Jul 1998

Effects Of Light Rail Transit In Portland: Implications For Transit-Oriented Development Design Concepts, Kenneth Dueker, Martha J. Bianco

Center for Urban Studies Publications and Reports

In the Portland, Oregon, region many local planners have embraced the neotraditional planning concept in the form of transit-oriented development (TOD). One of the primary components of transit-oriented development, light rail transit (LRT), has been in place in Portland long enough to provide data for analysis. Because neotraditional planners often emphasize LRT as a crucial element in decreasing auto use and in encouraging high-density development, this paper examines the effects of LRT in the Portland region including mode share, density, and property values. The empirical analysis provides evidence that light rail alone has not been sufficient to have an appreciable ...


Household Travel/Activity Decisions: Who Wants To Travel?, Catherine T. Lawson Jul 1998

Household Travel/Activity Decisions: Who Wants To Travel?, Catherine T. Lawson

Center for Urban Studies Publications and Reports

Researchers are using activity-based survey data to better understand the nature of the derived demand for travel. However, a strong theoretical construct for derived demand has yet to be developed. In order to understand the ramifications of considering travel as a derived demand, it is necessary to review some of the basic tenets of economics.

Some activities require travel (i.e. shopping or picking up children from daycare), while others are conducted entirely within the confines of the home. There is a set of activities that can be conducted either in or out of the home. A need to travel ...


Orbit: The Oregon Road Base Information Team, A Draft Summary Report, Mark Bosworth, Kenneth Dueker, Philip J. Wuest May 1998

Orbit: The Oregon Road Base Information Team, A Draft Summary Report, Mark Bosworth, Kenneth Dueker, Philip J. Wuest

Center for Urban Studies Publications and Reports

It is clear that transportation organizations across the nation are integrating GIS into operations at many different levels—from day to day use for data display, to full-scale enterprise level integration for operations, inventory management, research and a variety of other purposes. The cost of building and maintaining a current and accurate GIS database can be substantial within any given organization. For some smaller level organizations—small counties, cities or special districts, the cost of gathering data, organizing it and implementing systems within expensive software on an expensive operating platform can be downright discouraging. Also, as more complex data structures ...


Transit Time Internet Access, Janet Vorvick, Kenneth Dueker Mar 1998

Transit Time Internet Access, Janet Vorvick, Kenneth Dueker

Center for Urban Studies Publications and Reports

Transit Time Internet Access (TTIA) is a World Wide Web (WWW) application which delivers real-time bus schedule information to users of the Internet. TTIA allows a bus rider to request and receive schedule deviation information about a specific bus at a specific timepoint. This report explains the design of TTIA, the specifics of the implementation, the issues of scope, the problems that were encountered and some conclusions.


A Proposed Method Of Transportation Feature Identification, J. Allison Butler, Kenneth Dueker Jan 1998

A Proposed Method Of Transportation Feature Identification, J. Allison Butler, Kenneth Dueker

Center for Urban Studies Publications and Reports

Geographic information systems (GIS) are being increasingly deployed by transportation agencies to help them display, review, and utilize data. The primary items of interest are transportation facilities and services, which may take the form of highways, airports, bus routes, and seaports, among others. Using GIS software, transportation facilities are represented as geometric shapes; i.e., points, lines, and areas. However, it is increasingly apparent to GIS users in the field of transportation that a geometry-based approach is not sufficient.

The offered solution is to develop a feature-based GIS approach for transportation. The central requirement of such an approach is to ...


La Pine North: Two Futures, Deborah A. Howe, William A. Rabiega Jan 1998

La Pine North: Two Futures, Deborah A. Howe, William A. Rabiega

Center for Urban Studies Publications and Reports

This paper provides a vision of how accommodating such high growth may affect one rural residential area of the county, La Pine North. It will first draw a profile of La Pine North as it exists currently. Then, two possible futures for that space and its residents will be depicted. These futures represent the minimal and the most radical responses to the present and intensifying problem of nitrate/nitrogen pollution of ground water in the area. The "Restricted Growth" scenario assumes that the only response to the pollution problem will be the requirement of sand filter septic systems for replacement ...
