If your jurisdiction has installed countdown pedestrian signals, how would you rate the experience with using countdown pedestrian signals thus far?
Has your jurisdiction installed audible pedestrian signals (at new signals or retrofitted existing signals)?
Do you provide audible pedestrian signals at all crossings at a particular intersection or only at crossings used by those who need audible signals?
If you have installed audible pedestrian signals, how are they activated?
If you have installed audible pedestrian signals, how do people locate the activation device?
What other measures (other than crash rate per million entering vehicles and total crashes per year) do you use to determine if an intersection has a safety problem?
Do you apply night flashing signals?
If you do apply night flashing of signals, what criteria do you apply to determine if a signal should be flashed at night?
What advice can you provide to those who are contemplating the removal of a signal at an intersection where warrants for signalizations are no longer met because of changes such as traffic volume?
What do you consider to be the most important unresolved issues associated with signalized intersections?
