Revenue gathering doesn’t save lives better roads do

The road toll in NZ this labour weekend is already five. This is despite, for the second long weekend in a row, the Police dropping the tolerance level for speeding from 10km/h over limit to 5km/h.

Last long weekend the Police claimed that their lowering of the tolerance level saved lives, however, with the road toll in NZ being so volatile due to weather factors, and the size of the country being small it was more than likely just a statistic anomaly then any effect the Police had.

This long weekend has just shown that the effect of lowering tolerance does nothing to the limit and instead just trivialises fines and is nothing more than a revenue gathering exercise for police.

In NSW police do the same thing with double demerit points on long weekends. This does not save lives or encourages people to drive safer. Instead people who do take note spend more time looking at their dashboards instead of the road ahead.

A few weeks back former V8 Supercar Champion, Mark Skaife, was on a current affairs show on TV arguing that money should be spent on improving roads, increasing the speed limit, driver education and better cars than super strict enforcement of the driving rules.

I doubt any change will happen though when police and government policy continues to be driven on ticket quotas, revenue raising, and persecution of young drivers.

Bus lane fine being challenged

It is interesting to read today that a person is challenging the fine they got for driving in a bus lane: http://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=10595321

The $150 question of how far motorists can drive in a bus lane before making a turn goes to the Auckland District Court next week. Motorist John Foote says the law states it is the minimum distance necessary to safely make the manoeuvre. The Auckland City Council says 48m is a safe distance for a motor vehicle travelling at 50km/h. The council fines motorists $150 for travelling more than 50m in a bus lane. Mr Foote said this policy had resulted in the law being applied unlawfully and has sought a ruling.

Being a bit of a maths and science geek I decided to work out what is the minimum distance a car can stop in when traveling 50kmh. It turns out it is 24m if the car is in good shape, the road is dry, and the driver is fully aware (Stopping distances for cars – Road Safety Authority Rules of the Road) so say for instance it is a wet day this can affect things by a factor of two hence 2*24m = 48m. And this is the value that the Auckland City Council has set.

The major problem that I have with this is it is best case scenario maths. No consideration has been given to cars already stopped to turn within that 48m area, or the amount of distance required to change into the lane, or the fact that many cars travel faster than 50kmh, it may be the limit and the law but that does not mean people actually obey it. In the interests of safety it would be better to set it at a minimum of 65m which is the minimum distance at 60kmh on a wet day to stop.

None of this takes into account just how hard it is to judge precise distance when traveling at 50kmh or 13.8m/s while driving.

I hope the appeal succeeds, it is simply not safe with the number of factors involved to limit it at 48m. 100m would be a much more sensible solution.
