OTREC explores best practices for relocating the homeless

Posted on September 18, 2013

OTREC researchers dedicated some time to helping Department of Transportation staff members face a problem that isn’t strictly part of their job description: how best to deal with homeless individuals and households living in DOT rights-of-way and rest areas.

As owners of some of the largest stretches of public land, DOTs have to maintain the land for public use, but may lack resources to address the social welfare aspects of the stewardship of public land.

Homeless individuals and families sometimes seek shelter in rest areas, drawn to the facilities available there. When an established homeless encampment begins to interfere with the rest area’s intended function or threaten the safety of its users, the state DOT may need to intervene.

In 2010, the Baldock Restoration Group relocated 37 homeless households from the Baldock Rest Area near Wilsonville, Oregon. Due to its scale, the Baldock Rest Area relocation provided OTREC researchers with a unique opportunity to analyze the process and consider how best to respond to issues of this nature in the future.

OTREC research looks into bus safety performance monitoring and analysis

Posted on September 9, 2013

Generally, public transit is safer than other personal travel modes. However, not all transit modes are created equal: compared with other forms of transit, buses have a higher safety incident rate.

For example, while buses in fixed route service accounted for 39% of the transit industry’s passenger miles in 2009, their associated casualty and liability costs accounted for 51% of the industry total. In 2010 TriMet, the Portland, Oregon region’s transit provider, formed a safety task force to review its bus operations.

The task force recommended that TriMet develop a comprehensive performance monitoring program to better integrate safety in its planning practices. Like other urban transit providers, TriMet was already sending safety performance information to the Federal Transit Administration’s National Transit Database. The task force recommended seeking a deeper understanding of the types of incidents that are occurring, and of when, where, and why they occur. The task force also recommended that operators complete a recertification program annually to ensure that safe driving practices remain fresh.

In addition to keeping operators current on their safety training, the annual recertification program presented researchers with a unique opportunity to gain a firsthand perspective of the safety risks that bus operators encounter on a daily basis. Thus a survey of operator perceptions of safety risks was added to the training exercise. Investigators James G. Strathman and Sung-Moon Kwon, of Portland State University, explored those survey results.

OTREC research looks into effects of traffic signal optimization

Posted on August 30, 2013

An OTREC project recently took an in-depth look at the travel-time and health-related effects of a new implementation of a state of the art adaptive traffic system.

Southeast Powell Boulevard is a multimodal urban corridor connecting highway US-26 through Portland, Oregon. The corridor is highly congested during morning and evening peak traffic hours. In October 2011, an adaptive traffic system called SCATS was deployed.

The primary function of SCATS, or Sydney Coordinated Adaptive Traffic System, is to mitigate traffic congestion. Using sensors (usually inductive loops) at each traffic signal, the system tries to find the best cycle time and phasing along the corridor as traffic demand patterns change.

In this integrated multimodal study, OTREC researchers looked at the corridor’s traffic speed and transit reliability, before and after the implementation of SCATS. In addition, a novel contribution of this study was to study the link between signal timing and air quality.

Pronovost bicycle lecture inspires advocacy and teamwork

Posted on August 28, 2013

The Initiative for Bicycle and Pedestrian Innovation (IBPI) opened the Ann Niles Transportation Lecture series Monday, August 26 with a talk by Jean-Francois Pronovost, the vice president for development and public affairs at advocacy group Vélo Québec.

The Ann Niles lecture series serves as a legacy to Ann Niles, who was a strong advocate for livable neighborhoods and served on many boards and committees related to transportation in Portland.

OTREC and IBPI are proud to be part of an ongoing collaborative effort to make Portland a more livable city.

EV Roadmap 6 expands electric vehicle awareness

Posted on August 14, 2013

John MacArthur, OTREC’s Sustainable Transportation Program Manager, was a panel moderator at this year's EVRoadmap 6 workshop.

The EV Roadmap workshop series has established itself as the Pacific Northwest’s premier electric vehicle gathering, with a goal of increasing the visibility and understanding of electric vehicles.

Co-sponsored by Portland General Electric and Portland State University, the event supports the shared goal of building a stronger, more sustainable transportation landscape.

The sixth annual EV Roadmap workshop, "Drivers Take the Spotlight," was a continuation of this fruitful partnership. The event was held at the World Trade Center in Portland on July 30-31, 2013. MacArthur moderated a panel titled "Not All Drivers Need Four Wheels." This panel focused on odd-sized electric vehicles such as e-bikes.
