Abstract: Findings will be presented on an evaluation of two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland aimed at providing a more separated and comfortable experience for cyclists. The SW Broadway cycle track (near PSU) and the couplet of buffered bike lanes on SW Stark and SW Oak were evaluated to understand how they are functioning on multiple levels. Each facility involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities were evaluated after they had been in place for approximately one year. Data collected to support this evaluation consisted of surveys of multiple user groups for each facility type, and video data collected by the City of Portland Bureau of Transportation at intersections along each of the routes to understand the facilities' impact on traffic flow, operations and user interactions.

Abstract: A new way of measuring Level of Service for bicycles, pedestrians, and transit is planned for the next Highway Capacity Manual. Are these the right tools to help us plan and build the system we want? If not, what answers do these tools give us and how should we use them? This presentation will review the approaches to multi-modal Level of Service at the national and local levels and discuss efforts to validate the HCM methods. It will also cover the effect of our LOS policies on climate change and explore ways that we might tweak our analysis to get a more accurate picture of the transportation system for all users.

 Much has been written about millennials and their travel choices, both in the popular press and academic journals. The common theme of the storyline in the popular press is that millennials are driving less, owning fewer cars, and/or not getting their driver’s license. As a complement to that, they are early adopters of new modes, such as car sharing, bike sharing, and ridehailing. One assertion is that they would rather be using their mobile device in a Lyft car or on transit, than sitting behind the wheel. While the popular press often attributes these shifts to fundamental changes in attitudes or values, research from academics such as Noreen McDonald tells a more complicated story. McDonald found that economics, both decreased employment and the overall dampening in travel demand, explain much of the decrease in millennials’ driving. Switching modes did not, though attitudes and electronic...

I recently completed a national poll of people living in urban areas in conjunction with the National Association of Realtors® on Community and Transportation Preferences. The overall results are posted here. The survey included 3,000 adults living in the 50 largest urban areas in the U.S. (That includes suburban areas, as well as denser urban cores.) Here are some highlights related to bicycling.

1.    Less than one in five people have biked in the past month.

Overall, 72% of the adults surveyed said they were physically able and know how to ride a bike. Of those, 25% had ridden in the past month. (The survey was conducted in mid-May, so weather was reasonable.) That means only about 18% of adults in these urban areas biked recently. Most of the people who had biked, rode only for exercise (60%, or 15% of those who are able to bike), while the others (40%, or 10% of those who are able to bike) made at least some bike trips for transportation, such as to work, school, shopping, etc.
Note: From here on I will be focusing only on those people who are physically able and know how to ride a bike.

2.    There are gender and generational gaps.

This isn’t a big surprise, but women were less likely to bike than men,...

OVERVIEW

Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research.

In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience.

In this study, we use a high-resolution millimeter-wave (mmWave) radar sensor to obtain a relatively richer radar point cloud representation for a traffic monitoring scenario. Based on a new...

The overall goal of this research was to quantify the safety performance of alternative traffic control strategies to mitigate right-turning-vehicle/bicycle collisions, often called "right-hook" crashes, at signalized intersections in Oregon.

A two stage experiment was developed in the OSU high-fidelity driving simulator to investigate the causal factors of right-hook crashes at signalized intersections with a striped bike lane and no right-turn lane, and to then identify and evaluate alternative design treatments that could mitigate the occurrence of right-hook crashes.

Experiment 1 investigated motorist and environmental related causal factors of right-hook crashes, using three different motorist performance measures:

  1. visual attention,
  2. situational awareness (SA) and
  3. crash avoidance behavior.

Data was collected from 51 participants (30 male and 21 female) turning right 820 times in 21 different experimental scenarios. It was determined that the worst case right-hook scenario occurred when a bicycle was approaching the intersection at a higher speed (16 mph) and positioned in the blind zone of the motorist. In crash and near crash situations (measured by time-to-collision) the most common cause was a...

Summary: Signalized intersections often rely on vehicle detection to determine when to give a green light. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) includes an on-pavement marking and curbside sign that public agencies can use to indicate where cyclists should position themselves while waiting at an intersection. This presentation reviews the effectiveness of current markings, signs, and other methods used to help cyclists properly position themselves over detection.
