Improving Walkability Through Control Strategies at Signalized Intersections

Principal Investigator: Sirisha Kothuri

Co-Investigator: Christopher Monsere

The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle ... Read More

Rapidly Expanding Mobile Apps for Crowd-sourcing Bike Data to New Cities

Principal Investigator: Sean Barbeau

Co-Investigators: Nevine Georggi , Julie Bond

Cities such as San Francisco, Atlanta, and Portland are using novel methods of data collection to learn more about the use of their bicycle infrastructure. These data can help transportation planners better design or upgrade bicycle facilities. San F ... Read More

Evaluation of Electric Bike Use at Three Kaiser Permanente NW Employment Centers in Portland Metro Region

Principal Investigator: John MacArthur

Co-Investigator: Jennifer Dill

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership but the Oregon bike manufacturing industry is quickly growing. Oregon’s electric bike (e-bike) mar ... Read More

Connecting people to places: spatiotemporal analysis of transit supply using travel-time cubes

Principal Investigator: Steven Farber

Transit planning traditionally emphasizes the spatial dimension of accessibility; networks are built to bridge locations in the city with the assumption that the provision of spatial connectivity is equivalent to providing people with access to their ... Read More

Improving Trip Generation Methods for Livable Communities

Co-Investigator: Nico Larco

This NITC report offers a multimodal framework for transportation impact analysis – a welcome tool for professionals in many cities seeking more detailed data about non-drivers. Headed by Kelly Clifton of Portland State University and Nico Larco of ... Read More

Transportation Cost Index: A Comprehensive Performance Measure for Transportation and Land Use Systems and its Application in OR, FL, and UT

Principal Investigator: Liming Wang

Co-Investigator: Jenny Liu

MAP-21 and state laws are placing increasing emphasis on using comprehensive transportation performance measures that include mobility, safety, economy, livability, equity, and environmental to guide transportation decision-making. One of the toughes ... Read More

Metropolitan Centers: Evaluating local implementation of regional plans and policies

Principal Investigator: Richard Margerum

Co-Investigators: Keith Bartholomew , Rebecca Lewis

One of the emerging strategies in metropolitan regions for integrating transportation and land use is to promote development around higher density mixed use centers (metropolitan centers). Considerable research has focused on the design and performan ... Read More

Trip and Parking Generation at Transit-Oriented Developments

Principal Investigator: Reid Ewing

The decision of how best to allocate land around transit stations is a debated topic, with transit officials often opting for park-and-ride lots over active uses such as multifamily housing, office, and retail organized into transit-oriented developm ... Read More

Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots

Principal Investigator: Miguel Andres Figliozzi

Co-Investigator: Robert Bertini

Transit travel time, operating speed and reliability all influence service attractiveness, operating cost and system efficiency. These metrics have a long-term impact on system effectiveness through a change in ridership. As part of its bus dispatch ... Read More

Assessing State Efforts to Integrate Transportation, Land Use and Climate Change

Principal Investigator: Rebecca Lewis

Co-Investigator: Rob Zako

Climate change is increasingly recognized as a threat to life on earth. “Continued emissions of greenhouse gases (GHG) will cause further warming and changes in all components of the climate system. Limiting climate change will require substantia ... Read More
