Red Light Running Menace

You hear and read this refrain often from drivers who complain about cyclists and are not in favour of more bike infrastructure -

"As soon as those cyclists start obeying the rules of the road and stop zig-zagging, running red lights, rolling through stop signs, blah blah blah...then I'll give them more respect..."

I got so sick of hearing and reading it that I decided to REALLY  watch other drivers when I was walking, and especially driving.  And what I saw, after looking a lot more closely kinda freaked me out.
 
If you spend any amount of time walking and cycling in Calgary, you know that many drivers blow red lights regularly and roll right hand turns on red lights with abandon.  The Calgary Herald reported on the issue a couple years ago - and to quote the article, "the picture isn't always pretty".

No shit.  There is a pedestrian/cyclists hit by a car almost twice a day in this city.  The total number of bikes + people hit by cars in 2011 was 733 based on Calgary Police Service statistics.

I've also done my own anecdotal study of the issue while walking to work along 17th Ave SW a few times in the last 4 months and my observations are just as scary.

Basically, I walked from 45 St SW to the shop and along the way stopped at the signalized intersections and counted the red light runners over the course of a complete signal cycle.  These are the intersections I stopped at - 37 St, 33 St, 29 St, 26 St, 24 St, and Richmond Rd.

The truly scary part - the vast majority of intersections had at least 1 driver run/roll a red, more often, more than just 1.

Here's what I was able to sort out -

There are close to 1000 signalized intersections in the city



It takes 2-4 minutes for a full signal cycle



In an effort to be conservative, lets use the rush hours as our timeframe - 6:30-8:30am and 4:30-6:30pm - just 4 hours - instead of an entire 24 hour day.  And lets also only use 1/3 of the signalized intersections, again to stay on the conservative side of things.

So, we have...

- observed 1.3 infractions per signal cycle
1.3

- lets use a longer 4 minute signal cycle, giving us 15 cycles per hour
1.3x15=19.5 infractions per hour

- then use the 4 hour time window
19.5x4=78 infractions in 4 hours

- then the 329 (third of the 1000ish signals in the city)
78x329=25662 infractions at 1/3 of Calgary's intersections in 4 hours

- which works out to a conservative estimate of 6415 per hour!

6400+ red light runners and rolling red light right turn infractions are happening every daylight hour - day after day, month after month- you get the idea.  And the real numbers are probably much higher.  Yet, there is no obvious enforcement of this dangerous driver behaviour, no police crackdowns or blitzes - no TV/radio spots encouraging good behaviours, no newspaper articles - it's as if everyone is resigned to believe that the death and mayhem is just a cost of doing business in our car dominated society.

Where is the traffic enforcement?  Where is the awareness campaigns for drivers, pedestrians, and cyclists?  Where is the outrage at all the suffering that we don't need to be experiencing or paying for in lost productivity, insurance claims, and lives shortened?

The next time you read or hear someone ranting that cyclists don't deserve safe spaces to travel in, remember these numbers and remember where the true menace lies - often behind the wheel.
