Development Of A Multi-Class Bicyclist Route Choice Model Using Revealed Preference Data, Joseph Broach, John Gliebe, Jennifer Dill Dec 2009

Development Of A Multi-Class Bicyclist Route Choice Model Using Revealed Preference Data, Joseph Broach, John Gliebe, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Existing regional travel forecasting systems are not typically set up to forecast usage of bicycle infrastructure and are insensitive to bicyclists' route preferences in general. We collected revealed preference, GPS data on 162 bicyclists over the course of several days and coded the resulting trips to a highly detailed bicycle network model. We then use these data to estimate bicyclist route choice models. As part of this research, we developed a sophisticated choice set generation algorithm based on multiple permutations of labeled path attributes, which seems to out-perform comparable implementations of other route choice set generation algorithms. The model was ...


Equity Analysis Of Portland’S Draft Bicycle Master Plan – Findings, Jennifer Dill, Brendon Haggerty Sep 2009

Equity Analysis Of Portland’S Draft Bicycle Master Plan – Findings, Jennifer Dill, Brendon Haggerty

Urban Studies and Planning Faculty Publications and Presentations

Portland's current bicycle network has brought the city into the national spotlight as a leader in the provision of cycling infrastructure. As the city looks forward to 2030 with ambitions of becoming a truly world-class bicycling city, it is clear that if the Draft Plan is fully implemented, nearly all of the city will be covered by a dense network of bikeways. The question of equity in the future is therefore not so much one of network coverage or lack of coverage, but of project priority and timing of implementation. The current network, while outstanding relative to other cities ...


Evaluation Of Short Duration Unscheduled Absences Among Transit Operators: Trimet Case Study, James G. Strathman, Joseph Broach, Steve Callas Sep 2009

Evaluation Of Short Duration Unscheduled Absences Among Transit Operators: Trimet Case Study, James G. Strathman, Joseph Broach, Steve Callas

Urban Studies and Planning Faculty Publications and Presentations

This report analyzes factors contributing to short duration (one to three days) unscheduled absences among operators at TriMet, the transit provider for the Portland, Oregon metropolitan region. The analysis draws on a wide array of operator-specific information recovered by transit ITS technologies in combination with information from the agency’s human resources, scheduling, incident, and customer relations databases. The likelihood of an absence is estimated in relation to personal characteristics, employment status, aspects of assigned work, service delivery and performance indicators, temporal factors, and customer feedback. The findings can be used directly to support extraboard planning practices. More generally, the ...


Review Of The American Far West In The Twentieth Century. By Earl Pomeroy, Carl Abbott Jul 2009

Review Of The American Far West In The Twentieth Century. By Earl Pomeroy, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

After publishing his path breaking study The Pacific Slope: A History of California, Oregon, Washington, Idaho, Utah, and Nevada in 1965, Earl Pomeroy embarked on the even larger task of writing a history of the American West in the twentieth century. The present volume is the result, deeply researched by Pomeroy over four decades and completed after his death in 2005 by his student and friend Richard Etulain. The book is a fascinating mix of carefully presented details and wide-ranging topical coverage. Pomeroy expanded his "Pacific Slope" vision to include Alaska, Hawaii, the rest of the Rocky Mountain states, and ...


"Green" Transportation Taxes And Fees: A Survey Of Californians, Asha Weinstein Agrawal, Jennifer Dill, Hilary Kathleen Nixon Jun 2009

"Green" Transportation Taxes And Fees: A Survey Of Californians, Asha Weinstein Agrawal, Jennifer Dill, Hilary Kathleen Nixon

Urban Studies and Planning Faculty Publications and Presentations

This report explores public opinion on a new and promising concept―green transportation taxes and fees. These are taxes and fees set at variable rates, with higher rates for more polluting vehicles and lower rates for those that pollute less. This approach to transportation taxes and fees adapts the traditional transportation finance system to achieve two critical public benefits at once: encouraging drivers to choose more environmentally-friendly transportation options and raising revenue for needed transportation programs. To test public support for green transportation taxes and fees, the authors conducted a random telephone survey of 1,500 Californians that asked respondents ...


Paving The Way: Recruiting Students Into The Transportation Professions, Asha Weinstein Agrawal, Jennifer Dill Jun 2009

Paving The Way: Recruiting Students Into The Transportation Professions, Asha Weinstein Agrawal, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

The transportation industry faces a growing shortage of professional engineers and planners. One key strategy in solving this problem will be to encourage more civil engineering and urban planning students to specialize in transportation while completing their degrees, so that employers have a larger pool of likely recruits. However, very little is known about how these students choose a specialization. To help fill that gap, this report examines the factors that lead civil engineering undergraduates and urban planning masters students to specialize in transportation, as opposed to other sub-disciplines within the two fields. The primary data collection methods were web-based ...

Presentation and paper from 2008 "Toward One Oregon" Conference. A revised version of this presentation was published in the Oregon Historical Quarterly, 110(1), 74-95.


Spatial Patterns Of Air Toxins In The Region, Linda Acha George, Vivek Shandas Jan 2009

Spatial Patterns Of Air Toxins In The Region, Linda Acha George, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

This Atlas draws on the Portland Air Toxics Assessment (PATA) study to explore the regional variation of air quality. The PATA study presents an extraordinary opportunity to think about how the creation of new information can help us better plan our cities, but it also challenges us to think about the impacts of the choices we make.


From Urban Frontier To Metropolitan Region: Oregon's Cities From 1870 To 2008, Carl Abbott Jan 2009

From Urban Frontier To Metropolitan Region: Oregon's Cities From 1870 To 2008, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

An essay is presented which compares the development of Portland, Oregon, to the growth of other cities in the state. Particular focus is given to its economic stability and political influence. The changing relationship with Oregon's population, economics and cultural relations in the different parts of the state is examined. In addition, the urban-systems approach shows three equal periods in the state's development with close-in neighbors in modern economic geography.
