Due to the layout of my city and neighborhood I am regularly a motorist and pedestrian. Is a pedestrian I find the countdown timers to be exceptionally helpful in deciding to cross or not.
As a motorist I find them even more helpful as in my city we are subjected to random length yellow lights. It is never my intention to run a yellow light however in some intersections if you stop for a yellow light you may find yourself sitting at the yellow for up to 15 seconds. When the random length yellows were initially silently implemented there were a rash of rear-end collisions for vehicles stopping at intersections.
I would propose that drivers are entitled to more information rather than less. Drivers should see a countdown for the length of yellow lights as well as Green and Red lights.
This would allow motorists to make educated decisions. Currently drivers compelling their vehicles in a given direction hoping that the deities responsible for fate happen to be in their favor.
The additional information should come at the cost of zero tolerance. Currently we refer to collisions as accidents inferring that fault may not lay with the motorist.
Giving drivers more information should make them fully responsible. Run a red light = lose your license. Run a red and hit someone = go to jail.
Most people I've ridden with who seem compelled to run red lights seem to do so in an effort avoid intersections that dont perform the function of directing traffic but rather provide the function of blocking traffic:. IE light signals that sit red or turn RED with no opposing traffic or pedestrians. Get rid of broken intersections that punish people for obeying traffic signals and new drivers wont learn bad habits/existing drivers wont have bad habits reinforced.
