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 …

Sharing Transportation Gis Data, Kenneth Dueker, Paul Bender, Jihong Zhang

Center for Urban Studies Publications and Reports

Updating and maintaining Geographic Information Systems-Transportation data (GIS-T data) is proving difficult. Different database formats needed to support diverse applications leads to inconsistencies and inaccuracies, and duplication in updating. Dueker and Butler (1998) have proposed an Enterprise GIS-T data model that unbundles the various components of transportation data (network links, cartography, and attributes) to facilitate generating application-specific networks, and which eases updating and maintenance. However, developers of existing application-specific databases that employ integrated data models that bundle the network link with cartography and attributes are reluctant to step back to an intermediate form for managing their data. Consequently, attention is …

A Framework For Gis-T Data Sharing, Kenneth Dueker, J. Allison Butler

Center for Urban Studies Publications and Reports

This paper develops a framework and principles for sharing of transportation data. The framework is intended to clarify roles among participants, data producers, data integrators, and data users. The principles are intended to provide guidance for the participants. Both the framework and the principles are based on an enterprise GIS-T data model that defines relations among transportation data elements. The data model guards against ambiguities and provides a basis for the development of the framework and principles for sharing of transportation data. There are two central principles. First is the uncoupling of graphics, topology, position, and characteristics. Second is the …

Analysis Of Induced Travel In The 1995 Npts, James G. Strathman, Kenneth Dueker, Thomas W. Sanchez, Jihong Zhang, Ann-Elizabeth Riis

Center for Urban Studies Publications and Reports

In this paper we estimate the relationship between road capacity and vehicle miles of travel (VMT) from a sample of 12,000 respondents from 48 urban areas in the 1995 Nationwide Personal Transportation Survey (NPTS). Our approach seeks to account for the effects of residential location, employment location, and commute mode choice in estimating the effect of capacity on VMT. VMT is found to be directly related to road capacity, as well as indirectly related through the influence of road capacity on residential and work place densities.

Why Campaigns For Local Transportation Initiatives Succeed Or Fail: An Analysis Of Four Communities And National Data, Mti Report 00-01, Peter Haas, Kristen Sullivan Massey, Linda O. Valenty, Richard Werbel

Mineta Transportation Institute

As funding from state and national sources has dwindled and demands for relief from traffic and congestion have grown, local governments and transportation agencies are increasingly left to develop their own sources of enhanced revenues. Frequently the bid to increase available revenues comprises a local ballot measure, enabling the citizens served by these governments and agencies to express their preferences for or against increased taxation in support of an improved transportation system. What determines the success of campaigns in support of such ballot measures? To answer this question, this report includes the use of two different approaches and data sources. …

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.

Bus Transit Operations Control: Review And An Experiment Involving Tri-Met’S Automated Bus Dispatching System, James G. Strathman, Thomas J. Kimpel, Kenneth Dueker

Center for Urban Studies Publications and Reports

An operations plan contains information on the provision of transit service, including intended service levels, vehicle availability, and driver schedules. Agency resources would be utilized efficiently if the operations plan could be executed without disruptions in service. When service disruptions occur, the aim of operations control is to optimize system performance given the current state of the system (Wilson et al., 1992). This typically involves actions intended to either return service to schedule or restore headways separating vehicles. Disruptions in service impose costs on transit providers in the form of reduced productivity and on passengers in the form of increased …

Cheating Via Online Paper Mills In Logistics Education, Kathleen H. Gruben, Cathy Owens Swift, Luther (Trey) Denton

Journal of Transportation Management

The growth of e-business is providing businesses and entrepreneurs the opportunity to develop niches targeting one of the largest groups of Internet users: university students. Unfortunately, one of these niches is online term paper mills, where students can purchase university quality term papers and then submit them in class as their own work. The purpose of this paper is (1) to identify what online term paper services are available; (2) to determine how many logistics term papers are offered by these services; and, (3) to suggest strategies that can be used by logistics faculty to suppress use of these materials.

Terrorism And The Global Supply Chain: Where Are Your Weak Links?, Kathryn Dobie, L Milton Glisson, James Grant

Journal of Transportation Management

For many years, managers have chosen to ignore the risks associated with acts of terrorism that can potentially and catastrophically affect the global supply chain. As producers and suppliers become more tightly tied through long term relationships, common communications and information technology, events affecting one member of the supply chain can have a profound impact on the ability of the rest of the network to operate. The purpose of this discourse is to highlight the linkages which leave a supply chain vulnerable in the case of direct or indirect disruption caused by unexpected terrorist activity.

Effect Of Oregon's Axle-Weight-Distance Tax Incentive, Anthony M. Rufolo, Lois M. Bronfman, Eric Kuhner

Center for Urban Studies Publications and Reports

Oregon s weight-mile tax was amended in 1990 to provide for a lower tax rate for trucks weighing more than 80,000 pounds if they added axles. The additional axles within a weight class reduce the amount of road damage. The tax break was largely based on equity considerations, since trucks within a weight class tend to do less road damage if they have more axles; however, the tax reductions also created an economic incentive to add axles and thus reduce road damage. This article is a report on attempts to determine if the tax break actually led to an increase …

The Lloyd District is a high-density commercial and residential district located a short distance from downtown Portland, Oregon. Parking and transportation problems in the District have been a source of increasing contention for nearly a decade. As a result. in September of 1997. the City of Portland implemented a Lloyd District Partnership Plan, which consists of a number of elements aimed at curbing SOY use for the commute to and from the District. This plan included parking pricing in the form of meters, w'here on-street parking had previously been free: discounted transit passes: and other transportation demand management (TOM) strategies. …

Land Use And Growth Impacts From Highway Capacity Increases, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This analysis examined the historical relationship between land use changes and the location of capacity increasing highway projects in the State of Oregon from 1970 to 1990. Aerial photography for 18 cities was used to delineate the extent of urban development in each time period. A geographic information system (GIS) was used to assemble the data. Using this data, a logit regression model tested the significance of geographic variables such as proximity to highway projects, land use zoning classification, city size, and other spatial characteristics. The analytical methods used in this study incorporated a set of commonly used techniques to …

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 …

Exploring Alternative Purchasing Strategies: Just-In-Time Or Just Enough?, Julie J. Gentry, Matthew A. Waller, Scott B. Keller

Journal of Transportation Management

What are the prevalent purchasing strategies used by manufacturing firms to purchase components that are critical to the quality of their most important products? This research reports the findings from data on purchasing strategies collected from 248 companies. The data indicate that although firms seem to be moving away from a transaction-based purchasing strategy towards "partnership" relations necessary for successful just-in-time strategies, firms are likely to embrace one of four hybrid purchasing strategies that on a spectrum would fall somewhere between the two "pure" strategies. These identified strategies offer purchasing managers viable alternatives to moving directly into a just-in-time environment.

Maritime Unions And The U.S. Merchant Marine, Richard L. Clarke

Journal of Transportation Management

U.S. maritime unions have played a vital historical role in both the defense and the economic development of the United States. The economic and the political forces that helped shape and promote the growth of U.S. seafaring labor unions changed dramatically in the 1990s. Maritime union membership in the United States has fallen by more than 80 per cent since 1950. Inflexible union work rules and high union wage scales have contributed to this decline. Recent regulatory and industry changes require a new union approach if U. S. maritime unions are to survive the next decade.
