Friday Transportation Seminar: Barriers to “New Mobility”: A Community-Informed Approach to Smart Cities Technology

Friday, September 28, 2018, 12:00pm to 1:00pm PDT

Friday Transportation Seminars at Portland State University have been a tradition since 2000. With over 450 seminars presented and recorded (access the archive of seminars here), we host both visiting and local scholars to share the latest in research, technology, and implementation in transportation.

EVENT OVERVIEW

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found that by lowering costs and improving service for public transit, ridesharing and active transportation, smart mobility systems could address many of the needs of transportation disadvantaged communities....

Webinar: Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies

Tuesday, October 16, 2018, 10:00am to 11:00am PDT
Webinar: Addressing Bicycle-Vehicle Conflicts with Alternate  Signal Control Strategies on Oct 16, 2018

EVENT OVERVIEW

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Addressing Bicycle-Vehicle Conflicts with Alternate Signal Control Strategies, published in April 2018, is the first study to explore bicycle signal control strategies for addressing bicycle-vehicle conflicts. This study analyzed the operational impacts of traditional concurrent phasing, leading bike intervals (LBI), split leading bike intervals, and exclusive bike phasing in a microsimulation environment, and explored the safety impacts of traditional concurrent phasing, leading bike intervals, split leading bike intervals, and mixing zones using video-based conflict analysis. The microsimulation analysis revealed increased delays due to LBI, split LBI...

Friday Transportation Seminar: “Transportation Wallet” Program: TDM Strategies at the Portland Bureau of Transportation

Friday, November 30, 2018, 12:00pm to 1:00pm PST

EVENT OVERVIEW

The Portland Bureau of Transportation (PBOT) is expanding its Transportation Wallet service to keep Portland moving. People who live or work in the NorthWest Parking District can now purchase a "Transportation Wallet" – three transportation passes (a $684 value) for only $99. A portion of the parking permit fees that NW residents and employees pay go to provide Transportation Wallet's discount. The expansion of the program follows after a successful launch of the Transportation Wallet in partnership with the Central Eastside Industrial District Council, where PBOT teamed up with the parking district to encourage walking, taking transit, and bicycling in the districts. The Transportation Wallet is one of many approaches to address parking demand and congestion in these two dense areas of Portland. Switching even just a few trips from driving to other modes creates more available parking and helps alleviate traffic, a win for everyone, no matter how you get around.
