Co-Evolution Of Transportation And Land Use: Modeling Historical Dependencies In Land Use And Decision-Making, Lei Zhang, Wei Zu, Mingxin Li Nov 2009

Co-Evolution Of Transportation And Land Use: Modeling Historical Dependencies In Land Use And Decision-Making, Lei Zhang, Wei Zu, Mingxin Li

TREC Final Reports

The interaction between land use and transportation has long been the central issue in urban and regional planning. Models of such interactions provide vital information to support many public policy decisions, such as land supply, infrastructure provision, and growth management. Both the transportation and land use systems exhibit historical dependencies in policy decisions. For instance, the expansion of a roadway today will change travel demand patterns, and make certain other roads more or less likely to be expanded in the future. A specific land supply decision made at one point in time, by changing the relative attractiveness of other areas …


Evaluating The Effectiveness Of The Safety Investment Program (Sip) Policies For Oregon, Christopher M. Monsere, Lisa Diercksen, Karen Dixon, Michael Liebler Oct 2009

Evaluating The Effectiveness Of The Safety Investment Program (Sip) Policies For Oregon, Christopher M. Monsere, Lisa Diercksen, Karen Dixon, Michael Liebler

TREC Final Reports

The Oregon Department of Transportation (ODOT) Safety Investment Program (SIP) seeks to allocate safety funds in a manner that maximizes safety benefits on preservation projects and at specific high-crash locations. The SIP philosophy targets highway sections for investment with the premise that the most effective use of safety dollars to save lives is to invest in areas where the most people are being killed or seriously injured in traffic crashes. The SIP categorizes five-mile roadway sections on a 1-5 rating based on the number of crashes in a three year period; with five (5) being the most crash prone section. …


Practical Approximations To Quantify The Impact Of Time Windows And Delivery Sizes On Freight Vmt In Urban Areas, Miguel A. Figliozzi Oct 2009

Practical Approximations To Quantify The Impact Of Time Windows And Delivery Sizes On Freight Vmt In Urban Areas, Miguel A. Figliozzi

TREC Final Reports

This paper studies approximations to the average length of Vehicle Routing Problems (VRP). The approximations are valuable for strategic and planning analysis of transportation and logistics problems. The research focus is on VRP with varying number of customers, demands, and locations. This modeling environment can be used in transport and logistics models that deal with a distribution center serving an area with daily variations in the demand. The routes are calculated daily based on what freight is available. New approximations and experimental settings are introduced. Average distance travelled is estimated as a function of the number of customers served and …


Expanding Service Learning Models In Transportation, Robert Parker Sep 2009

Expanding Service Learning Models In Transportation, Robert Parker

TREC Final Reports

This OTREC education project links experiential education with local transportation planning through a collaborative partnership between the University of Oregon, the Lane Transit District, and the cities of Eugene and Springfield. The Community Planning Workshop (CPW) is an experiential/service learning program affiliated with the Department of Planning, Public Policy and Management at the University of Oregon. Through this service learning program, graduate students learn professional planning skills while assisting communities in actual planning and policy projects.

The project results include: (1) the completion of the following six deliverables: EmX Evaluation Framework Document, EmX Stakeholder Perceptions Document, Bus Rapid Transit Case …


Transferring Community-Based, Active Transportation Gis Assessment Tools Nationwide, Marc Schlossberg, Nico Larco Aug 2009

Transferring Community-Based, Active Transportation Gis Assessment Tools Nationwide, Marc Schlossberg, Nico Larco

TREC Final Reports

“Livability” has recently been declared one of four top priorities by the Secretary of the U.S. Department of Transportation (USDOT), and the USDOT, the Environmental Protection Agency (EPA), and the Department of Housing and Urban Development (HUD) have entered into an historic partnership to address the issue. Ultimately, this term refers to the quality of life within one’s community and the ease, comfort, and joy with which one can access places he or she want to go. For most Americans, their neighborhoods have been designed to predominantly accommodate the automobile, and more active forms of transportation such as walking and …


Developing Corridor-Level Truck Travel Time Estimates And Other Freight Performance Measures From Archived Its Data, Christopher M. Monsere, Michael Wolfe, Heba Alawakiel, Max Taylor Stephens Aug 2009

Developing Corridor-Level Truck Travel Time Estimates And Other Freight Performance Measures From Archived Its Data, Christopher M. Monsere, Michael Wolfe, Heba Alawakiel, Max Taylor Stephens

TREC Final Reports

The objectives of this research were to retrospectively study the feasibility for using truck transponder data to produce freight corridor performance measures (travel times) and real-time traveler information. To support this analysis, weigh-in-motion data from each of the twenty-two stations in Oregon were assembled, processed, and uploaded in the WIM data archive is housed under the Portland Transportation Archive Listing (PORTAL) umbrella at Portland State University’s Intelligent Transportation Systems Lab. Nearly 42,000,000 truck records were successful uploaded to the archive dating back to July 2005. Two separate algorithms necessary for this research were scripted, tested, and validated. The closest stations …


Improving Travel Information Products Via Robust Estimation Techniques, David Maier, Kristin A. Tufte, Rafael J. Fernández Moctezuma Mar 2009

Improving Travel Information Products Via Robust Estimation Techniques, David Maier, Kristin A. Tufte, Rafael J. Fernández Moctezuma

TREC Final Reports

Traffic-monitoring systems, such as those using loop detectors, are prone to coverage gaps, arising from sensor noise, processing errors and transmission problems. Such gaps adversely affect the accuracy of Advanced Traveler Information Systems. This project will explore models based on historical data that can provide estimates to fill such gaps. We build on an initial study by Mr. Rafael J. Fernandez-Moctezuma, using both a linear model and an artificial neural network (ANN) trained on historical data to estimate values for reporting gaps. These initial models were 80% and 89% accurate, respectively, in estimating the correct speed range, and misclassifications were …


Factors Affecting Behavioral Changes In Response To Road Fees: Some Analyses Of The Effect Of Attitudes, Transit Access, And Fuel Efficiency On Changes In Miles Driven, Anthony M. Rufolo Feb 2009

Factors Affecting Behavioral Changes In Response To Road Fees: Some Analyses Of The Effect Of Attitudes, Transit Access, And Fuel Efficiency On Changes In Miles Driven, Anthony M. Rufolo

TREC Final Reports

Objective The Oregon Department of Transportation conducted a test of an innovative technology to replace fuel taxes with mileage fees. In the test, some vehicles were charged a flat fee per mile and others were charged differential fees that were higher for travel in the Portland metropolitan area during weekday peak hours and lower for other travel. I was charged with developing the database for the project and analyzing the behavioral responses of the participants. The database is quite extensive, including responses to three surveys as well as information on mileage in various categories. The experiment ended on April 1, …
