Reply to comment by hubbyofhoarder in Fern Hollow Bridge is OPEN! by MaynardWaltrip

Thank you for the lesson on cue versus queue, I will remember to proofread all of my posts on this anonymous social media platform of little to no importance more carefully going forward.

As for the data, since you’re the expert, feel free to go through PennDOT’s GIS data to prove your case, you can access it here: https://data-pennshare.opendata.arcgis.com/datasets/a17c20bf71dd40fea24363bb9f0ae0e4

What I see are minimal changes in AADT for adjacent roadways over the closure period, with only a 14% increase from July 2019 to July 2022 on Penn Ave, for example.

Looking at the City of Pittsburgh’s data (which you can access here: https://data.wprdc.org/dataset/traffic-count-data-city-of-pittsburgh), I see that the average speed of travel for the October 2019 period of recording for Braddock Ave was 30 mph, with a 95th percentile speed of 38 mph. The city does not have data for the Fern Hollow Bridge, but given its speed limit of 35mph, it stands to reason the speeds of vehicles on that stretch is faster than the 30mph average observed for Braddock Avenue.

Given that the average risk of death for pedestrians involved in a car collision doubles from 25% to 50% with a 10 mph increase in speed from 32 to 42 mph (42 mph is likely very close to the Fern Hollow avg speed given the wide pattern of avg speed = limit + ~5-10mph), this difference is not insignificant by any means, and supports the general necessity of bike lanes on this stretch of roadway: cyclists are twice as likely to experience a fatal collision on this stretch versus those adjacent.

But, then again, I don’t live there, I live ten whole minutes away, so what do I, and these very absolute, quantitative data know anyway…

No, it doesn't. If you're inbound on Fern Hollow you're either coming from South Braddock, having made a turn or you've passed through, you know, a traffic control device that slows cars as part of its function due to merging traffic patterns. If you're outbound, you're again passing through a traffic light from a wider road to a single-lane road that has cars parked along its length nearly all of its length most of the time.

South Braddock is long and straight with relatively few traffic devices along its length. Fern Hollow either starts or ends with a traffic light, depending on direction. Not the same, your assumptions are shit.

>free to go through PennDOT’s GIS

You did, and what you got is a bullshit comparison of two non-comparable stretches of road.

Monkey-see, monkey-do is not part of my schtick.
