Why doesn't that traffic signal ever turn green? An evaluation of roadway markings for cyclists

The video begins at 1:37.

View slides

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.

Beyond the Bike Hook: Linking Bicycles and Transit

The video begins at 2:58.

Abstract: While TriMet and other transit agencies serve many commuters by having racks for bikes on trains and buses, large bike parking facilities in global capitals of urban bicycling provide the key link between bikes and transit. Following the lead of European and Asian cities, the Portland region is starting to develop a network of bike-transit facilities; TriMet is piloting smart bike parking technology in the form of electronic bike lockers and "Bike & Rides". This presentation discusses the background and planning for bike-transit integration in the region and shares insights into bike-transit travel patterns, habits, and market segmentation gained from recent rider surveys.

Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike

Speaker: Joseph Broach, Ph.D. Candidate, Portland State University
Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip? 

Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.

Webinar: Radar Point Cloud Segmentation using GMM in Traffic Monitoring

PRESENTATION ARCHIVE

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...

Measuring and modeling cyclists’ comfort and stress levels

Some researchers have tried to categorize cyclists’ levels of traffic stress utilizing facility or traffic data that can be readily measured in the field, such as motorized travel lanes, travel speeds, and type of bicycle infrastructure.

This seminar will present data and modeling results utilizing two novel data sources:

(a) real-world, on-road measurements of physiological stress as cyclists...

Cyclist Compliance at Signalized Intersections

Watch video

View slides

Summary: Although the running of red lights is perceived by motorists as a commonplace behavior for cyclists, little research has been done on the actual rates of cyclist compliance at signalized intersections. Furthermore, little is known about the factors that influence cyclist non-compliance. This research seeks to illuminate the rates of and reasons for infringement against red lights using video footage and survey data from cyclists in Oregon. 

Bio: Sam became interested in transportation and planning while studying abroad in Freiburg im Breisgau, Germany. After benefiting from the efficient transit service and excellent walkability there, he came back to the states with a gusto for safe, efficient, and environmentally sustainable transportation. After finally figuring out what to do with his Civil Engineering degree, he enrolled in Portland State. Sam's research interests include cyclist behavior and the comprehension and safety implications of new infrastructure. Originally hailing from Kansas, he has grown weary of Wizard of Oz jokes but is otherwise happy to call Portland his home, especially with the abundance of good coffee, micro brews, and stellar pie that PDX has to offer.
