The Motivations Of Exurban Commuters Within A Region, Judy Seppanen Davis Nov 1989

The Motivations Of Exurban Commuters Within A Region, Judy Seppanen Davis

Center for Urban Studies Publications and Reports

This case study of the Portland, Oregon, region analyzes and compares the emerging commuting patterns of exurban, small town, and suburban households. The analysis is based on a mail survey of 1408 households who purchased homes in 1987. By examining the types of households moving to exurbia, their reasons for moving, and the impacts of their moves on journey-to-work a picture is drawn of the forces shaping exurban development and the implications of this type of development for transportation planning and policy.


Sampling Bus Ridership At The Route Level: Initial Results From Efforts To Improve The Precision Of Sample Estimates, James G. Strathman Sep 1989

Sampling Bus Ridership At The Route Level: Initial Results From Efforts To Improve The Precision Of Sample Estimates, James G. Strathman

Center for Urban Studies Publications and Reports

UMTA's Section 15 reporting requirements establish precision standards and corresponding sampling plans for estimating bus ridership at the system level. However, many transit providers are interested in recovering data with sufficient precision to permit ridership analysis at the route level. One outcome of extending a system sampling plan to route level data collection and analysis would be a large increase in the sample sizes required to achieve a reasonable standard of precision. Given the costs involved in expanding the data recovery process beyond what is required for Section 15 reporting, alternative means of improving the precision of route level data …


Challenges Confronting Metropolitan Portland's Transportation Decision-Making Regime, Sheldon Edner, Sy Adler, Peter B. Morris Sep 1989

Challenges Confronting Metropolitan Portland's Transportation Decision-Making Regime, Sheldon Edner, Sy Adler, Peter B. Morris

Center for Urban Studies Publications and Reports

In this paper we discuss the structure and dynamics of this consensus process through an exploration of a series of challenges to the regime. These challenges include: (1) cultivating new sources of project finance, as the federal government reduces its contribution; and (2) integrating transport projects with regional and local land use plans designed to manage urban growth; in the context of (3) intensifying competition between -business centers within the region, as rapidly growing suburban areas seek transport projects that will facilitate locally-oriented economic growth. We first discuss the institutional and normative elements of the regional consensus process in historical …


Site Location Study For An Integrated Traffic Data Collection System: Phase 1 Report, Kenneth Dueker, Richard Ledbetter, Bruce Rex Sep 1989

Site Location Study For An Integrated Traffic Data Collection System: Phase 1 Report, Kenneth Dueker, Richard Ledbetter, Bruce Rex

Center for Urban Studies Publications and Reports

Improved technology for counting, classifying, and weighing vehicles in the highway traffic stream is becoming increasingly available. Research has been undertaken to make effective use of these new technologies, not just to replace current data collection programs of counting, classifying, and weighing with more efficient versions. This reports on the Phase I research, which had three major objectives;

  • a literature review to guide the analysis of alternative methods;
  • a statement of requirements to modernize and integrate the data collection programs of traffic counting, vehicle classification and truck weights, and to identify the type and use of traffic data for design, …


An Evaluation Of Automatic Passenger Counters: Validation, Sampling, And Statistical Inference, James G. Strathman Sep 1989

An Evaluation Of Automatic Passenger Counters: Validation, Sampling, And Statistical Inference, James G. Strathman

Center for Urban Studies Publications and Reports

While automatic passenger counters (APC's) offer the potential for cait effective data recovery and management, they also introduce new complications in the data recovery process. This report addresses three issues associated with the implementation of APC's, based on an evaluation of the recent experiences of the Tri-County Metropolitan Transportation District of Oregon (Tri-Met). First is the issue of validation, which is concerned with both the recovery and accuracy of APC passenger data. The second issue concerns the development of a sampling methodology for APC's compatible with UMTA's Section 15 reporting requirements. Third is the issue of inferring system-level ridership from …

Constructing The 1990 Public Transportation Study Process: Reflections Of The 1988 Research Team, Janice Dean, Sheldon Edner Aug 1989

Constructing The 1990 Public Transportation Study Process: Reflections Of The 1988 Research Team, Janice Dean, Sheldon Edner

Center for Urban Studies Publications and Reports

The 1988 Oregon Public Transportation Study provided a solid foundation of information about Oregon’s transportation providers. In particular, it furnishes information on which revenue sources members of the industry are utilizing, expenditure patterns, capital and operating revenue needs, the protected increased demands for public transportation, and the ability of provides to makes use of available resources in their strategic planning. The study also substantiated that many members of the industry do not identify themselves as transportation providers, particularly the Special Need Transportation providers. The research process also revealed several additional factors about the process of collecting information that should be …


Augmented Analysis Of Oregon's Special Need Transportation Providers, Janice Dean, Sheldon Edner, Kenneth Dueker, Transportation Northwest (Transnow) Aug 1989

Augmented Analysis Of Oregon's Special Need Transportation Providers, Janice Dean, Sheldon Edner, Kenneth Dueker, Transportation Northwest (Transnow)

Center for Urban Studies Publications and Reports

This analysis extends the work originally provided in the 1988 Oregon Public Transportation Study by the same authors. The intent is to focus attention on a particularly diverse segment of the public transportation community, special need providers (SNT), in an effort to further specify and define their nature and role in the public transportation system. The results of this analysis are intended to assist the Oregon Department of Transportation, Public Transit Division, with its efforts to implement Oregon's public transportation programs and to provide a basis for further specifying additional research needs in this area.

1988 Oregon Public Transportation Study, Sheldon Edner, Kenneth Dueker, Janice Dean Apr 1989

1988 Oregon Public Transportation Study, Sheldon Edner, Kenneth Dueker, Janice Dean

Center for Urban Studies Publications and Reports

Oregon continues to face challenges in public transportation. The lack of a consistent and comprehensive framework of state policy is making local efforts to meet public transportation demands harder and fails to exploit economic and transportation opportunities for improving the vitality of the state. The absence of continuous and stable state financial assistance has weakened the state/local partnership in providing public transportation services and kept mobility for many Oregonians at a minimal level. Finally, as the federal role in funding transportation declines the need for aggressive state leadership increases. The following recommendations for Legislative and Executive action are offered as …
