Number and Severity of Arizona bike-MV crashes

TL;DR? Here’s the bottom line:
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.

It’s been noted that the number of reported Bike-MV crashes reported by police in Arizona have seen a mysterious sharp decrease; even as the number of MV crashes in general has risen. In round numbers through the 2009-2016 period, Bike-MV crashes have fallen by about a third, while crashes overall have increased by 20%. This time period covers the economic downturn following the Financial Crisis of 2008 and subsequent recovery. That trend has been used to explain the MV crash rate; but it doesn’t seem to have anything to do with Bike-MV rates; which would logically rise with more traffic and more (MV) traffic crashes.

Fewer crashes would be a good thing of course, but it feel like there’s something else going here. Also, the number of fatalities, while statistically small,  remained relatively flat but above their longer-term trend of 24 (rolling 10 yr average 2007-2016; refer to internal spreadsheet \crashReports\asdm\AZstats.xls)
