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. …

Understanding Delivery Routes In Urban Areas, Miguel Figliozzi

TREC Project Briefs

Supply chains and urban areas cannot thrive without the efficient movement of goods. A recent study indicates that commercial vehicles carrying goods or providing services account for, on average, almost 10 percent of the total vehicle miles traveled (VMT) in medium to large urban areas. A predominant share of these trips takes place within a multi-stop tour. In order to develop a well-organized system for moving freight through urban areas, it is crucial to understand and quantify how routes and distribution decisions affect commercial vehicle flows and VMTs.

In the past, transportation planning models have focused on passenger movements but …

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 …

The Built Environment, Neighborhood Safety, And Physical Activity Among Low Income Children, Jessica Greene, Debbie Daniel

TREC Final Reports

There is a growing body of evidence that environmental factors are related to physical activity and active modes of transportation. There is a separate body of research that links neighborhood safety to physical activity. This study used a cross sectional telephone survey of 801 parents/guardians of low income children in Florida to bridge these literatures and examine the independent relationship of the built environment and neighborhood safety on childrens' physical activity.

In multivariate regression models we find that neighborhood safety is a more consistent predictor of low income childrens' physical activity. In neighborhoods where parents reported that there was a …

Transporting The Economy, Miguel Figliozzi

TREC Project Briefs

The efficient, timely and reliable movement of freight is a critical responsibility of the transportation system and strategically important to the U.S. economy. Today, Americans purchase billions of dollars worth of goods over the Internet for home delivery, routinely sent using nextday- express packages. They also expect globally produced fresh fruits, flowers and vegetables to be available year-round. These shipments move over an extensive freight transportation system comprising millions of vehicles and thousands of miles of road, track and pipeline infrastructure, all supported by sophisticated information technology and operated, managed and maintained by a large, specialized labor force.

Environmental Durability Of Reinforced Concrete Deck Girders Strengthened For Shear With Surface Bonded Carbon Fiber-Reinforced Polymer, Christopher Higgins, Matthew R. Dawson, Mikal M. Mitchell, Gautam Sopal, A. Ekin Senturk

TREC Final Reports

This research investigated the durability of carbon fiber-reinforced polymer composites (CFRP) used for shear strengthening reinforced concrete deck girders. Large beams were used to avoid accounting for size effects in the data analysis. The effort included determining the role of freeze-thaw, moisture, and fatigue on structural performance and developing analytical design procedures that account for durability.

The results showed that moisture infiltration behind the CFRP, combined with freeze-thaw, was critical in reducing shear panel stiffness and shear capacity. Long-term moisture exposure alone produced only a minor decrease in shear capacity. Freeze-thaw, combined with fatigue, had little effect on shear capacity …
