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 …

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

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

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 …

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, nevertheless …

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 …

"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 their views …
