The New Panama Canal In A Global Context, Herman L. Boschken

Faculty Publications, School of Management

Without the "container revolution" (1970-present) and its redesign of seaport and maritime-trade infrastructures, globalization as we know it would not exist. With the recent enlargements of the Panama and Suez Canals, many new implications for U.S. economic trade are unfolding. This presentation at the Commonwealth Club of California, outlines recent changes in world trade and infrastructure development, and poses five factors that will likely determine winners and losers in the unfolding developments of this highly competitive world trade-route system.

Green Loop Swpdx Concept Plan: Alignment And Design Treatment Recommendations For The Southwest Green Loop, Ashley Eaton, Brian Gunn, Jake Adams, Kate Washington, Mohd Meidiansyah

Master of Urban and Regional Planning Workshop Projects

The Green Loop SWPDX project was conducted by five students in partnership with the Portland Bureau of Planning & Sustainability Urban Design Studio and Portland State University's Campus Planning Office. It explores potential alignments and design treatments for Portland's Green Loop, specifically with the southwest downtown quardrant of the Central City. The southwest quadrant of the Green Loop links the South Park Blocks to the non-automobile Tilikum Crossing bridge. The Green Loop SWPDX project explores both large and small-scale possibilities for creating a sense of safety and a place for cyclists and pedestrians in the Central City. This document reports …

Where Does Bicycling For Health Happen? Analysing Volunteered Geographic Information Through Place And Plexus, Greg P. Griffin, Junfeng Jiao

Research Collection College of Integrative Studies

Research on the role of bicycling for health through physical activity has been limited by the lack of information on where bicyclists ride. New big data sources available through smartphone-based applications provide a rich source to provide bicycle volume data more comparable to the scale of information available for automotive and public transit modes. In the case of smartphone apps for fitness tracking, results of this data can be used similar to the growing application of global positioning systems for automotive travel surveying. The authors evaluate data from Travis County, Texas for the purpose of determining where bicyclists ride, primarily …

What Do Americans Think About Federal Tax Options To Support Public Transit, Highways, And Local Streets And Roads? Results From Year Six Of A National Survey, Asha W. Agrawal, Hilary Nixon

Mineta Transportation Institute

This report summarizes the results of year six of a national random-digit-dial public opinion poll asking 1,503 respondents if they would support various tax options for raising federal transportation revenues, with a special focus on understanding support for increasing revenues for public transit. Eleven specific tax options tested were variations on raising the federal gas tax rate, creating a new mileage tax, and creating a new federal sales tax. Other questions probed perceptions related to public transit, including knowledge and opinions about federal taxes to support transit. In addition, the survey collected data on standard sociodemographic factors, travel behavior (public …

Comparing Data Quality And Cost From Three Modes Of On-Board Transit Passenger Surveys, Asha W. Agrawal, Stephen Granger-Bevan, Gregory Newmark, Hilary Nixon

Mineta Transportation Institute

This report presents the findings from a research project investigating the relative data quality and administration costs for three different modes of surveying bus passengers that produce results generalizable to the full passenger population. The three modes, all of which used survey methods distributed or administered onboard the transit vehicle, were: self-complete paper surveys, self-complete online surveys, and interviewer-assisted tablet-based surveys. Results from this study indicate several implications for practitioners choosing a survey mode. First, and most importantly, the analysis reinforces the point that there is no single, best survey mode. The choice of mode must depend on an agency’s …

The Green Loop Swpdx Workshop Project, Brian Gunn, Kate Washington, Jake Adams, Ashley Eaton, Mohd Meidiansyah

PSU Transportation Seminars

The Bureau of Planning and Sustainability proposes the construction of the Green Loop, a 10-mile linear public open space proposed in the West Quadrant Plan update that will further link the east and west sides of the Central City. In addition to physically affirming both sides of the river as part of the Central City, the Green Loop is expected to create a second ring of pedestrian and bicycle access, much like the East Bank Esplanade and Tom McCall Waterfront Park, that will draw activity to retail further from the river.

The Green Loop addresses both the City of Portland’s …

Transforming A Historic Highway In Small Town Mosier Into A Vibrant Main Street, Amanda Davidowitz, Kaleidoscope Student Planners

PSU Transportation Seminars

Kaleidoscope Student Planners, a group of six students in the Master’s of Urban and Regional Planning program at Portland State University, are working with Mosier, Oregon’s City Council to develop the Slow Mo’ Main Street Concept Plan. The goal for the project is to develop conceptual designs and programmatic recommendations for historic Highway 30 (which runs through the town), to help ensure that Mosier’s Main Street reflects community priorities, supports a thriving downtown, and creates a safe and inviting corridor for people traveling on foot, by bike and by motor vehicle. During this seminar we will reflect on our process …

VMT, population and income data will be noted with implications on local transportation planning.

Development Of A Pedestrian Demand Estimation Tool: A Destination Choice Model, Christopher D. Muhs

PSU Transportation Seminars

There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Planners, engineers, and others seek improved tools to estimate pedestrian demand that are sensitive to environmental and demographic factors at the appropriate scale in order to aid policy-relevant issues like air quality, public health, and smart allocation of infrastructure and other resources. Further, in the travel demand forecasting realm, tools of this kind are difficult to implement due to the use of spatial scales of analysis that are oriented towards motorized modes, vast data requirements, and computer processing limitations.
