ADOT 2010 Crash Facts

ADOT’s 2010 Motor Vehicle Crash Facts has just been released.

Highlights are the total number of fatalities continued to fall; there were a total of 762 persons killed in 2010, a 5% decrease from the year before.

There were 19 bicyclists killed on Arizona’s road in collisions with motor vehicles in 2010, which compares favorably with the 25 killed in 2009. That means there are two (possibly three) missing from this tally for 2010.

The MOST COMMON DRIVER VIOLATION is (remains) Speed too fast for condition

There were 106,177 crashes in total, of which 1,914 were bike-MV crashes.

Dangerous by Design

[updated regularly; the one release in May 2014 can be found at smartgrowthamerica.org I don’t think anything much has changed Phoenix and Arizona still rank “high” (bad) ][direct download of 2016 edition]

While we’re on the subject, t4america.org released the latest version of their recurring report Dangerous By Design 2011; where metro-Phoenix has a recurring, starring role as a particularly dangerous place for pedestrians — the 8th worst rate in the US. The only places significantly higher are basically several (!) metro areas in Florida.

Bad for pedestrians tends to translate into bad for motorists and bicyclists, as well — in other words, we’re all in this together.  Arizona’s motorist fatality “VMT rate  is over twice as deadly as Massachusett’s. The disparity in per capita rate, since Arizonans drive more miles, is even worse…. more”

But you are not likely to hear anything about how or if or why Arizona isn’t closing the gap; or even that a gap exists! — rather that deaths overall have merely fallen. Here is a typical new-release-style story: azfamily.com story

Back to the DbyD report, they have this concept called PDI, the Pedestrian Danger Index; Phoenix-metro at 132 is many times worse than, for example, Boston-metro at 21.6.

And just to throw out a factoid, for the year 2009 (the most recent year for which detailed stats are available) there were more bicyclists killed within the City of Phoenix (9) than were killed in the entire state of Massachusetts(6).

The population of Phoenix is 1.5M versus State of Massachusetts having 6.5M…. The C.O.P., accused rightly as being an enormous-sprawling place covers 516 square miles, the state of Massachusetts 7,840 square miles of land area.

John Allen’s blog reflecting upon the fact that in the DbyD report, the Boston-metro area came in dead last (SAFEST!) of all large metro areas in US — “Strange, isn’t it — the Boston area has repeatedly been derogated as supposedly having the nation’s craziest drivers”.

Arizona’s Rural Highway Traffic Safety Problem

A couple of days after the data was released, and somewhat to my chagrin, the arizonarepublic/news/articles/2011/09/02/20110902arizona-deadly-rural-roads.html did a fairly long and detailed piece on what ADOT is doing to identify and address rural highway problems… though, interestingly, the latest Crash Facts shows a steeper decline in rural as opposed to urban fatalities.

So far, no one that I know of, has said or suggested that Arizona’s high rate of rural fatalities is what accounts for Arizona’s overall high traffic fatality rate. Perhaps that is so?

As mentioned in the article, rural fatal crashes tend to be single-vehicle — though that is a little misleading because a bike-MV, or ped-MV crash is defined as a single-vehicle.

Here are the number of fatal crashes split by urban/rural for 2009 and 2010:

Peds fatal crashes, total/urban/rural: 156 / 102 / 54 ( 2009: 121 / 77 / 44)

cyclists killed, total/urban/rural:         19 / 17/ 2 ( 2009: 25 / 17 / 8 )

(all inclusive) Number of fatal crashes, total / urban / rural: 698 / 354 / 344 (2009: 709 / 299/ 410)
