With the current Govt looking to increase speed limits again in the name of "economic growth and improved productivity", it's useful to remind ourselves that past and current speed limit reductions have consistently seen much greater $$ gains from fewer deaths & serious injuries

@TheObserva2902 @AynRandy666 Interesting spin - the enforcement is mostly for drug/alcohol driving offences, which I think most people would agree should be "punished". Lower speed limits just induce people to slow down a bit (enforcement or not), which in turn reduces casualty numbers - basic physics

@GKoorey @AynRandy666 So it's good to see people punished you reckon. Now we are cutting to the real reasons you people want to lower limits. It's to exert power and control and punish people.

Simeon Brown insisted on raising speed limits near schools because his 4WD driving moron supporters just can't wait a few seconds. Now of course kids are getting run over left right and centre. Just like people predicted. This is on YOU, Simeon Brown #nzpol

@ZooNealand @AynRandy666 Due to increased enforcement, plus all the lower speed roads/streets still out there around NZ - you're welcome...

@RobertAtatuPen @AynRandy666 Largely due to increased enforcement, which is good to see. But also because several roads & streets across the country still have lower speed limits (unlike Auckland that caved in and reversed most of them)

@TheObserva2902 @AynRandy666 Some of that drop in road deaths is due to increased enforcement, which is great to see. But many many streets & roads in NZ still also have lower speed limits from the past couple of years (Auckland being the notable exception sadly), which also reduced casualty numbers

@AynRandy666 The road toll has dropped significantly since the speed limits went up. I believe the kid was hit by a cyclist. They need to get cyclists off busy roads. For safety.

@GKoorey @Jamesnotabot @GreaterAKL Yes I got the chart, but where is it from so I can validate the data, because new highways, barrier and safety changes during those time periods may have had an impact.

Three major crashes today on roads where the current NZ govt *increased* the speed limit (previously lowered for safety reasons) in pursuit of "productivity"? Serious injuries. Lengthy closures. Costly disruptions to lives, whānau, the transport network, our health system.

@TerryVercoe @Jamesnotabot @GreaterAKL That's a bit weird, that link should just take you a view-only version of a Word doc summarising the stats - I guess I can see if the SharePoint link has expired...

@LertzAdam @GreaterAKL Agreed, lots of different things can contribute to why crashes happen. But then the speed at the time of the crash significantly determines the resulting consequences...

@GKoorey @GreaterAKL Likewise drug/ alcohol impairment and excessive speeds should be excluded from speed limit stats. The posted speed limit has no impact on those causes.

@LertzAdam @GreaterAKL That's why we tend to wait a bit until there are enough crash numbers to try to identify any patterns - certainly I'll be monitoring things over the next few years...

@GKoorey @GreaterAKL Agree logic is that lower speed lower deaths and serious injuries. My issue is the inaccuracies of statistics/data used to measure. Eg in my area 3deaths in NZTA stats - 1 a suicide & two by a stationery vehicle. Not speed related but in the stats.

@AndyStig @GreaterAKL best to use statistics that don't link to any data - i guess you support that sort of statistic

@verminlionel @randomtwootera1 @GreaterAKL It's not about whether speed *causes* a crash - lots of factors often contribute. It's about the CONSEQUENCES of the resulting crash, depending on the speed at the time - that's basic physics

@TerryVercoe @Jamesnotabot @GreaterAKL Nope, the comparisons were made against similar road sections that didn't have their speed limits changed over the same time period - so traffic volume changes (whether during COVID or whenever) had the same effect on both of them

@Jamesnotabot @GreaterAKL James, these are the same people whom included the no traffic covid periods to claim lower speed limits saved lives, truth has no place on the road to "NetZero ideologies. Remeber potholes they took 180 million out of road maintenence budgets for advertising netzero during Labour

@LertzAdam @GreaterAKL Well, there have also been other fatalities on other roads recently increased - sure, early days, but let's remind ourselves again what happened when the speeds were previously lowered...

@GreaterAKL And you know already thst speed was the cause of all three.....? Not inattention, human mistake, tiredness, impairment....?? If it was excessive so you think a posted speed limit sign would make any difference....?? So many factors that could have been in play....

@chris_otautahi @tomforccc Funnily enough, City Council are currently investigating the safety effects of these stone Chch. Good example is Lincoln/Barrington intsn - from one of the worst crash records beforehand to no crashes since it was raised

I've been invited to this - not quite a "meet the candidates", more of a "talk about how local government can support our thriving arts scene" event hosted by Space Academy. Really looking forward to it!

@PostQuake @chrisluxonmp At least half of that cost is for reconstructing/improving road and utility infrastructure at the same time - you're welcome... And the calculated benefit:cost of the completed cycle network was at least 8:1 - show me the expressways that even produce a 2:1 B/C ratio...

Councils need to forget the fancy toilets and excessive bike lanes. Pick up the rubbish, fix the pipes, fill in the potholes. We’re passing legislation to get Councils back to basics and help keep your rates under control.

@Mike1104376788 @_ConnorSharp @GreaterAKL Sure, that's why most recent ones would need more time to get more robust findings - didn't stop them from all reducing though... A pity that the Akld urban ones now have to go back up. And the earlier ones have plenty of data to demonstrate their effectiveness.

@GKoorey @_ConnorSharp @GreaterAKL “Similar unchanged control sites”🤔 How long have the lower speed areas been operative🤔 2 years? Difficult to get Statistically sound info I would say. Still, keep torturing the data until it confesses.

Currently, Auckland Transport is in the process of increasing the speed limit of over a thousand local streets and roads across the city, without consultation or consideration to safety. 🧵

The last governments reduced speed limits randomly like a patchwork quilt throughout the region. They were clunky and annoying and It’s doubtful that they reduced any accidents. At a deeper level they were of course an “attack on the car” by ideologs who say they are concerned about safety and the environment, but really they hate capitalism and want the revolution. Just saying
