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

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 and...

Friday Transportation Seminar: Cycling Research and Practice in Australia: Insights from a Hybrid Approach

Friday, October 19, 2018, 12:00pm to 1:00pm PDT
Friday Transportation Seminar at PSU - Cycling Research and Practice in Australia: Insights from a Hybrid Approach (Marilyn Johnson)

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

Too often, there is a gap between research and action. For researchers, peer-reviewed scientific evidence is the benchmark of success, while for policy makers and practitioners, success is being able to apply findings in the ‘real world’.

Dr Marilyn Johnson is both a senior researcher at Monash University and a practitioner at the Amy Gillett Foundation, Australia’s not-for-profit cycling safety organisation. The seminar will be a speed-dating style presentation of the latest research studies on cycling in Australia, current cycling safety campaigns and programs and the intersection between research, policy and effective action.

Content will include: 

  • Cyclist safety on-boarding at Deliveroo, review, recommendations and actions; 
  • Engaging with experts on e-bikes; 
  • Changing the road rules to improve safe cycling; 
  • Cycling skills for girls and women; 
  • Vulnerable road user safety training (read: putting truck drivers on bicycles), and; 
  • A...

Friday Transportation Seminar: Driver Comprehension of Permissive Right-Turns with a Flashing Yellow Arrow (FYA)

Friday, October 26, 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

This research explored driver comprehension and behaviors with respect to right-turn signal displays with a focus on the Flashing Yellow Arrow (FYA) in a driving simulator and a comprehension survey. Flashing yellow arrows are used in place of other turn signals, such as solid green or flashing yellow or red circles, to indicate that drivers may turn after yielding to oncoming traffic. These turns are considered “permissive.” Turns where no conflicting traffic is present, such as those indicated with a green arrow, are “protected” turns. The flashing yellow arrow’s inclusion in the 2009 Manual on Uniform Traffic Control Devices sped up the signal’s adoption to indicate a permissive turn.

Results from a counter-balanced, factorial design were chosen to explore three independent variables separately: signal indication type and active display, length of the right-turn bay,...

Friday Transportation Seminar: Is Public Transit's 'Green' Reputation Deserved?

Friday, November 2, 2018, 12:00pm to 1:00pm PDT
Friday Transportation Seminar at PSU - Is Public Transit's 'Green' Reputation Deserved? (Justin Beaudoin)

EVENT OVERVIEW

While public transit has a reputation as a potential means to ameliorate the adverse environmental effects of automobile travel, there have been very few empirical studies of the marginal effect of transit supply on air quality. We explore whether any of the substantial improvement in air quality observed in the U.S. from 1991 to 2011 can be attributed to increased public transit supply by developing an equilibrium model of transit and automobile travel volumes as a function of the level of transit supplied. We then empirically analyze the effects of the level of transit supply on observed ambient pollution levels by applying an instrumental variables approach that accounts for the potential endogeneity of public transit investment to a panel dataset of 96 urban areas across the U.S. over the years 1991-2011. We analyze the effects of the level of transit supply on the following criteria pollutants: carbon monoxide, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. We find that - at the margin, and given existing urban travel regulations in place - there is no evidence that increased transit supply improves air quality; in fact, transit appears to lead to a small deterioration in overall air quality.

Friday Transportation Seminar: Portland’s Transportation Wallet: How Pricing Parking Can Create New Mobility Options

Friday, November 9, 2018, 12:00pm to 1:00pm PST

EVENT OVERVIEW

The Transportation Wallet is one of Portland’s newest parking and transportation demand management (TDM) strategies, designed to reduce parking demand while simultaneously offering new mobility options by bundling transit and bike share passes into one consumer product. Two of Portland’s managed parking districts have elected to add a surcharge to the cost of on-street parking permits, a portion of which is used to subsidize the cost of the Transportation Wallet. Residents and employees in the parking districts are eligible to purchase the Transportation Wallet at a fraction of the retail cost. As an added incentive to increase parking supply, people can trade in their on-street parking permits in exchange for free Transportation Wallets. Since the program’s full implementation in the past year, the number of parking permits issued in the districts has noticeably declined. Wallet holders report they are taking transit and bike share trips more, some of whom are new riders altogether, and many report driving less. The impact of the Transportation Wallet on the overall transportation system is promising, as people are replacing car trips throughout the city, with the highest concentration being in the two parking districts. Planning is already underway to expand the Transportation Wallet to offer more mobility options to a greater audience in more Portland neighborhoods.

Friday Transportation Seminar: Scenarios for Adoption of Autonomous Vehicle Technologies in Freight

Friday, November 16, 2018, 12:00pm to 1:00pm PST

EVENT OVERVIEW

Innovation adoption research has largely ignored organizational adoption, and little work has been done to understand or predict the adoption of innovations by freight organizations. Among the existing innovation adoption theoretical and methodological approaches this seminar will explore which are most appropriate methods for freight organizational adoption. The seminar will present a disaggregate market penetration model for freight transportation organizations adopting connected autonomous vehicle (CAV) technology and demonstrate an an application using a case study area in Memphis, TN. The seminar will highlight ongoing and future organizational adoption research for CAVs, and other innovations.
