Re: New York is the city that never moves

Meanwhile, accidents have gone up.

That's what would be expected for the Vision Zero paradigm. Crashes go up but their severity does not. The result is fewer deaths.

This is analogous to the reduction in highway deaths since Nader's "Unsafe At Any Speed." Highway crashes have not gone down. However, the redesign of automobiles: crumple zones; seat belts; air bags; etc. has resulted in greatly increased survivability in a crash.

Anyone can verify my statement regarding NYC. The NYPD crash reports are available from the City's Open Data Site. The data is from 7/1/2012. I've downloaded the data as of 11/26/2016. Here are the results for the same number of days for each year:

"year","crashes","injured","deaths"
2013;184327;50278;263
2014,187093,46658,247
2015,196631,46229,218
2016,204305,52891,205

N.B. the police data does not describe injury severity. The salient statistic for most crash analysis is KSI or killed or severely injured.

Also, the death statistic for 2016 may be artificially low. This isn't because of data cooking. There's sometimes a long delay between a crash and the actual death. Victims may linger for weeks or months before succumbing to their injury. Probably, the end of January 2017 would be a better date to analyze this data.
