PRESENTATION ARCHIVE
THE TOPIC
For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections.
Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in the field. Results show that a bicycle signal countdown timer elicited high comprehension rates. At all locations, cyclists indicated that the devices improved their waiting experience.
KEY LEARNING OUTCOMES
- Results of comprehension surveys on detection feedback devices
- Insights on improving bicycle infrastructure
THE RESEARCH
This seminar is based on a study funded by the Oregon Department of Transportation (ODOT). Read more about the project: Bicycle Detection and Feedback Assessment.
