Many years ago, I rang my bell and passed a middle aged woman running with giant Beats-style earphones on. Stopped at an intersection a few hundred yards ahead, and when she caught up to me she started berating me for not calling my pass. I commented that I did, and rang my bell, and she just grumbled for a while about how my bell needed to be louder. Theres just no pleasing some people. :/
So true Jabberwocky. I have enthusiastically resigned myself to the fact that I cannot count upon pedestrians along the trail to be cognizant of my approach. The level of situational awareness among pedestrians seems to be distributed in a stable ratio. It seems to be about a 50/50 distribution of pedestrians that are aware of their surroundings, and pedestrians that are oblivious to their surroundings. When I say "oblivious, I mean dangerously oblivious! Some may dispute the ratio, but I do believe it to be stable within a geographic area. So the ever present "oblivious pedestrians" must be dealt with in a safe manner.
I have ridden for two years, utilizing the Sena Bluetooth Communication helmet with my friend. The hands free communication has allowed us to experiment with pedestrians and their responses to various types of alerts using voice, bells, whistles, and road noise. I have the loudest decibel (127db) bike horn that I can find, and a front flashing light so bright, that some people comment when shielding their eyes, "are you trying to make me go blind"?
When following each other, the rear biker is able to gauge the response of pedestrians(s) to alerts, or no alerts by overhearing them, and observing their behavior. (side note: Male and Female couples are the most fun*). We have tried all types of alerts, non-alerts, at various speeds and proximity. We've ridden at times giving a loud warning to everyone. We've ridden at times offering no warning, just gliding by.
Most every pedestrians reaction is discussed, and sometimes they are quite amusing. Women tend to scream when startled, and then they laugh goofily once they come to their senses. We have passed thousands of pedestrians with dogs on leash (or not), holding hands, the elderly, kissing couples, mom's pushing baby carriages while toting three children on the trail, loose children and teens, and of course, the ubiquitous music listener wearing state of the art noise cancelling headphones.
I come away with these observations, cognizant that in the future I will most likely refine my observations.
1. Upon approaching a pedestrian on the same trail, slow down to a speed of 6 mph within the distance of 25 feet from pedestrian. After passing the pedestrian, proceed at speed. This principal is similar to that found in boating laws, wherein a boat must slow down to a "no-wake speed" when within a 100 foot distance to a swimmer.
2. On giving the alert? Yes, give the alert, but watch out, it's a crapshoot.
*The humor that is born out of our conversations using these bluetooth helmets, is priceless.
