A NITC research project from Portland State University introduces a method of cleaning up land use data, for use in improved transportation models.

Transportation and land use are closely interdependent. Considerable work is underway, in Oregon and elsewhere, to develop models that integrate the two.

Planners creating these models often spend the bulk of their time preparing data on the various land uses. Many times the data, gathered from diverse sources, is incomplete and requires the planner to find missing information to fill in the gaps.

In fields outside of transportation, there have been considerable advances in techniques to do this. Data-mining and machine-learning techniques have been developed, for example, to systematically detect fraud in credit data, reconcile medical records and clean up information on the web.

In the transportation modeling community, by contrast, most efforts to tackle the problem are tied to a specific model system and a chosen study area. Few have produced reusable tools for processing land use data.

Liming Wang, lead investigator of the project Continuous Data Integration for Land Use and Transportation Planning and Modeling, offers such reusable...

A project led by Portland State University researchers Chris Monsere and Miguel Figliozzi has been nationally recognized as one of sixteen high value research projects by the American Association of State Highway and Transportation Officials (AASHTO).

Each year at its annual meeting, AASHTO's Research Advisory Committee selects four projects from each of its four regions to form a "Sweet Sixteen" group of important and influential projects.

The project, “Operational Guidance for Bicycle-Specific Traffic Signals,” reviewed the current state of practice for bicycle signals and evaluated cyclist performance characteristics at intersections. The research has been used to inform an FHWA Interim Approval for bicycle signals.

Bike signals are beginning to be common in major cities throughout the U.S., with some engineering guidance available from the California Manual on Uniform Traffic Control Devices, the...

In a morning workshop on Sunday at TRB's annual meeting, Patrick Singleton of Portland State University was named the top-ranked Eisenhower Fellowship recipient

The session featured innovative research from second- and third-year Eisenhower doctoral fellowship recipients from top universities across the nation.

Singleton was one of four civil and environmental engineering students from PSU to be awarded the Dwight David Eisenhower Transportation Fellowship in 2014.

The paper he presented, "The theory of travel decision-making: A conceptual framework of active travel behavior," integrates theories from economics, geography and psychology to arrive at a unifying framework for understanding and predicting active travel decisions.

It examines the thought processes behind individuals' short-term travel decisions and explains the roles of activities, built environment factors, socio-demographics, perceptions, and habit in influencing those decisions.

Singleton's award marks the second year in a row that a Portland State student has taken the top honor, following Kristina Currans.

Singleton's adviser, Prof. Kelly Clifton, said she's proud of his accomplishment and the continued achievement of Portland State students. "It shows the strength of the program," Clifton said.
