Enforcement drops, crashes proliferate, people die

Tim Steller’s excellent (dare I say, stellar?) piece in the Daily Star: Enforcement drops, crashes proliferate, pedestrians die exposes the inexplicable sharp decline in traffic enforcement in the City of Tuscon by the Tuscon PD. Continue reading “Enforcement drops, crashes proliferate, people die”
Number and Severity of Arizona bike-MV crashes
[google doc spreadsheet gets updated more frequently but with statewide data only. At this moment, includes final data thru 2023, also highlights (suspected) “missing” hit and runs]
[quick update on 2021 Crash Facts data — the pattern continues, the total number of reported cyclist crashes was only 1025. Notwithstanding a historically high fatality count of 43]
[at some point, ADOT began “scrubbing” PDO. As explained in the 12th Edition of the crash from instructions, linked here, effective 8/2019 AZ law bumped up the PDO reporting threshold from $1,000 to $2,000. As can be seen easily at the spreadsheet linked at Crash Facts 2021, No-injury (and unknown injury) reports became exactly zero commencing with 2019).
In any event the PDO change would not explain all or even most of the dramatic decrease in reported non-fatal bicyclist crashes]
Something suspicious is happening in 7 larger cities in Arizona ( ‘Chandler’, ‘Flagstaff’, ‘Glendale’, ‘Gilbert’, ‘Mesa’, ‘Scottsdale’, ‘Tempe’). That’s mostly the largest cities in AZ, excluding Phoenix and Tucson. In these 7 places, reported low-severity bike-MV crashes have decreased dramatically comparing before versus after 2014; suggesting some sort of policy change.[and note: the PDO limit issue of 2019, explained immediately above, doesn’t explain it, either]

PD: Driver hit SUV, killed bicyclist in Glendale before hitting police car
[update: 9/28/2017 — driver charged w/ 2nd degree murder]
Impaired drivers remain a serious threat to bicyclists. And pedestrians. And other drivers. And passengers.
9/22/2017 “just after midnight” Bicyclist (60-year-old Peter Rankin) killed incidentally when a suspected impaired, speeding driver (Kevin Richard Hevel, 30) sideswiped another vehicle; jumped the curb onto the sidewalk where he struck and killed the bicyclist, kept going (of course) and continued on to rear-end a Glendale police cruiser. Near 59th and Glendale Ave, in Glendale, AZ. Continue reading “PD: Driver hit SUV, killed bicyclist in Glendale before hitting police car”

4 dead in I-17 wrong-way crash near Flagstaff
A driver driving the wrong way on the freeway killed all four occupants of the other vehicle. Police have not revealed why they think driver was driving the wrong way, however, they did note that this year
“…DPS arrested 52 people suspected of driving the wrong way… Ultimately, each of the 52 drivers arrested was found to be impaired”.
So, 100% of wrong-way drivers were impaired. Wrong way driving appears to be an impaired driver problem. Continue reading “4 dead in I-17 wrong-way crash near Flagstaff”
Arizona Crash Facts 2016
ADOT has released Crash Facts 2016 in the later part of June (of 2016), a bit later than normal; and I received the database from them sometime in July.
The graphical crash map has been updated and now contains 2009-2016 for both MV-bike and MV-ped crashes.
The Fatality Grid has been reconciled and contains some specifics on every bicyclist fatality in Arizona from 2009-2016
Signals knocked down by driver

Some dangerous driving knocked down a traffic signal in the median of Warner Road at I-10 sometime 8/1 or 2. It’s not known is the responsible person hit-and-ran or what.
This is right down the same road where a dangerous driver killed the Childtime sign in July 2016, and also where a dangerous driver killed a bus stop in Feb 2015.
Apparently, this sort of driving goes on all the time, but no one seems to care much. Lots of property damage. Continue reading “Signals knocked down by driver”
Bicycle rider killed in collision with bus in Mesa

7/26/2017 ~ 8:40am. News reports Eastbound Bus on McKellips near Country Club crashed headon with a cyclist traveling westbound in the eastbound lane.
It was approaching the intersection of McKellips with Grand according to the map location in the news story. In a later news story a police spokesperson identified the bicyclist as Shedrick Galloway, 46/M, and said he “was hit when he veered in front of the bus”.
Wrong-way riding is a pretty common contributing factor in bike-mv collisions, however this type where the bicyclist is thought to have veered into the path of oncoming traffic is pretty rare. Another later news story relates that the bicyclist wasn’t feeling well and had already called a friend to come pick him up; so perhaps (speculation) he suffered some sort of medical emergency that caused the veering.

Phoenix police: Bicyclist identified after being hit by suspected drunk driver
fatal incident 8/27/2016; This was reported in the media at the time but I had missed it.
Cyclist Thomas J. Butler 39/M; 43rd Ave, just north of Bethany Home Road. It’s not clear when police say things like “The bicyclist tried to ride across the street, not in a crosswalk”; and there are inconsistencies in the data file; unfortunately the crash report itself is unavailable from the given file number, so the world will never know: Continue reading “Phoenix police: Bicyclist identified after being hit by suspected drunk driver”
