It focused on the Arizona study because that was the only one out of the 35 that actually measured Motor Vehicle Collisions. The rest did not even attempt it in any controlled manner.
As stated, there are no meaningful studies that these cameras reduce accidents.
These cameras do nothing to improve safety. There is no meaningful scientific evidence that shows any difference improvement in safety.
Their only value is socioeconomic harm.
“after accounting for MVC increases in the control segment we found that neither camera placement nor removal had an independent impact on MVCs. In other words, speed cameras did not statistically contribute to an increase or decrease in the number of MVC.”
This one actually does need heathcliff to be humorous. Appreciate all your work in posting these!
For the record I did not downvote.
But I capitulate on your point. It would be great if every piece of software was written with resilience and uptime in mind.
As a former sysadmin that sounds like a dream. But I don’t think I have ever seen that with any mainstream program that I’ve had responsibility for. Does that mean all those programs were bad? I don’t think so. We wouldn’t need sysadmins if all programs were written the way you describe.
Programs can be written to auto rotate their logs, compact and reindex their db’s. Using browser updates as an example, they can even safely auto update and revert back on failure.
How many programs actually do these things? My experience is next to 0. But I wouldn’t call them all bad or poorly written programs.
No. Every good software program should write at least logs to disk. Every good database writes to disk. Add a new post, db will commit to the db and the db will grow in size.
Name any decent sized program where new content is added and I guarantee it writes to disk and will fail eventually if not maintained.
Don’t feel too bad, not only is 30 an arbitrary number, he doesn’t account for folks too young to understand something. I don’t think a 2 day old baby learning about the mentos thing should count. So either it’s more than 10,000 people per day or the age should probably stretch out to 60 or maybe even 75.
Of corse there are also the people like me who are forgetful and may not remember they heard something!
Did you build this box? Could be cpu thermal paste not properly applied.
I am in fact stating that there is no proof that they do anything to reduce collusions or deaths. I stated in my first comment that such proof does not exist.
These cameras are only deployed to generate revenue. There is no scientific basis for improved safety.
