I looked over the study to determine if there was a criteria for "yield" vs "non-yielding".
I think based on the study write-up under section "2.2. Pedestrian crossing", that yielding was based on:
- car in nearest lane is 200 yards away
- pedestrian placed one foot into crosswalk
- pedestrian attempted to make eye contact with driver
- driver reduces speed -> threshold for "safe to attempt"
- driver yields or does not -> fits criteria for "yields"
It isn't clear if they considered a failure by the driver to invigilate the entire crossing as a "failure to yield"; e.g. in my district, if a pedestrian is present in the cross walk at any part of the road, I cannot proceed full-stop, and that would be a "failure to yield" under my road laws act.
After thinking about this study, and attempting to not make myself look like a fool if my original issue was addressed, I noted a few more deficiencies in this study:
- road structure (other than mid-block crossing, and 35MPH; e.g. number of houses, other entry ways, number of business, two lanes or four lanes; traffic calming measures)
- road use (isolated neighborhood collector; retail zone; between two high-congestion areas; etc)
- volume of crossings by non-study participants
- recency of the crossing
- existing use of the crossing (inter-neighborhood? inter-shopping centre? school to park?)
- driver perceived age of pedestrians and pedestrian capability (infirm, underage, active)
This all leads into:
- driver awareness of existing pedestrian crossing
- driver familiarity with pedestrians at that crossing
- driver intention with the road
- brand new and underused crossing? old crossing with very low non-study volume?
- is 4x30 = 120 crossings at road 1 and road 2 high or low for that area?
I don't feel this study is useful in isolation, and I'd be irritated if someone used it as a basis for point-making.
