Global study calls for 20mph speed limit as standard in built-up areas

Campaigners call for an end to “the postcode lottery on pedestrian/cycling safety”

A new report from the International Transport Forum has called for 20mph speed limits as standard in built-up areas. The study examined road safety performance in ten countries after they changed speed limits or introduced automatic speed cameras and in all cases found a strong relationship between average speed and the number of crashes.

Part of the Organisation for Economic Co-operation and Development (OECD), the International Transport Forum is an intergovernmental organisation that acts as a think tank for transport policy.

Driver risks losing licence for repeatedly breaking 20mph limit

It looked at changes in speed limits in six countries and the introduction of automated speed enforcement in four more to gauge the impact on the number of collisions.

The report states that an increase in mean speed was accompanied by a higher number of crashes and casualties, while a decrease was associated with fewer crashes and casualties. In no case did an increase in mean speed coincide with fewer crashes or casualties.

The International Transport Forum therefore makes a number of recommendations.

  • Reduce the speed on roads as well as speed differences between vehicles
  • Set speed limits based on the Safe System principles, i.e. at a level that humans can survive without dramatic consequences in case of a crash
  • Introduce compensation measures where speed limits are increased; for instance, stricter enforcement or a safety upgrade of the road infrastructure
  • Use automatic speed control to effectively reduce speed

Working towards a Safe System, the authors proposed as reasonable speed limits:

  • 30 km/h in built-up and residential urban areas where motorised vehicles and vulnerable road users share the same space
  • 50 km/h in other urban areas with intersections and high risk of side collisions
  • 70 km/h on rural roads without a median barrier and a risk of head-on collisions

The report also notes that lower driving speeds generally improve citizens’ quality of life, especially in urban areas.

Rod King MBE, founder and director of the 20’s Plenty for Us campaign commented:

“This is yet another report coming to the firm conclusion that 20 is plenty where people live, work, play, shop and learn.

“Other countries have adopted a near universal 30km/h limit for urban and residential streets. Over 25% of the UK live in authorities who have also set 20mph as the right urban limit. The Scottish assembly is considering a bill to make 20mph the limit (with exceptions) for built up roads. It’s time to end the postcode lottery on pedestrian/cycling safety and general well-being in our residential and urban places by setting a 20mph default limit for built-up roads across the UK.”

Why not just reduce the speed to Zero mph and eliminate accidents altogether. No point in half measures. Seriously, 20 mph is way too slow.

For many roads, I'd agree.  Did you have a point?

Yes, my point is 20 mph is way too slow. Kids on pedal cycles would be done for speeding. Hussain Bolt would be done for speeding. My neighbour's cat would be done for speeding.

We already have 20 mph zones in areas where it makes sense, we don't need these zones everywhere. A max speed limit does not mean you have to drive at that speed. Always drive according to conditions and expect the unexpected. Don't start penalising drivers for driving safely when conditions allow. 20 mph is slow...

The max speed limits are for motorised vehicles, so they have no relevance to bikes, Hussain Bolt and/or neighbours' cats.

Unfortunately when people drive at considerably more than the stated speed limit (often 50% more) then lower limits may be the only way to get them to drive at a reasonable and responsible speed.

If limits were reduced by 10mph in most areas (excluding those already at 20) then safety would massively increase. There are very few national roads that aren't dual carriageways where driving above 50mph is necessary as all it does is get you to the next queue for a roundabout/set of traffic lights/junction, slightly more quickly.

Short of black box trackers being fitted to all cars then higher speed limits will always be broken,  humans by default will usually try to seek out advantages in life, and going a little faster than everyone else is one of those subconcious things that people do unless they have a reason to check their behaviour.

When our County Council announced the introduction of 20 limits in some residential areas the local police commander replied they could do as they wished but the force would not be enforcing those limits.  

Words failed me then and continue to do so.

I had a few angry driver behind me in Cambridge yesterday. I was doing about 30mph and was riding outside the far too narrow cycle lane, and the drivers wanted to overtake despite me cycling at the speed limit behind other traffic.

 

We need proper enforcement of speed limits, and better observance of rules by drivers as well as common sense (slowed by 2mph or so over 1 mile makes no real time loss).

 

The 20 mph limits in Cambridge are hardly ever followed by drivers, and some cyclists are often breaking them too, especially devilroo riders (fit the daily mail stereotypes perfectly)

Except for royal parks and promenades, speed limits don't apply to cyclists, so they can't break them.

Do they have any moral obligation to follow them? Fixie-boy managed to kill someone at less than 20mph.

Are you saying all cyclists should be morally obligded to fork out a couple of hundred on a GPS to know their current speed?

Get something for £5 from Aldi and google 700c circumference. There, saved you a couple of hundred.

Motorists have managed to kill people at considerably lower speeds than even that.  By your logic that would imply there's a moral obligation for them to go even slower, no?

 

I think there's certainly a moral obligation to be sensible.  I don't see that simply translates to 'obey speed limits intended for much higher-mass vehicles'.

I'm all in favour of reducing the speed limit but perhaps they could try properly enforcing the existing 30 miles per hour limit first!

I cycle quite fast but why are cars still trying to get past me in a 20 mph zone?

Why when I try to drive at the speed limit, either at 20 or 30, do I sometimes get angry drivers behind shaking their fists?

It's almost like it's deemed socially unacceptable to keep to the speed limit.  These attitudes need to change!

You speak sense.

Without changing the numbers on the speed limit signs we could make them refer to kilometres instead of miles. A nice cheap start.

yes, but Brexit. We won't be allowed to use kilometres, it'll all be furlongs and chains again.

That and geting drivers to not use their headlights in built up area, side lights are bright enough and the law is actually fairly clear you should not use headlights in built up areas. DRLs are also too  bright as well.

Whilst they're at it we should get rid of the blanket NSL, far too many roads are simply not safe with vehicles bombing along at 60mph with motorists simply not capable nor even wanting to slow down to a speed they can stop well within the space they can see to be clear.

Forcing manufacturers to build in speed limiters linked to an internal GPS or detection system so they can never go over the limit at least and then for government to spend some money getting every single road reviewed. Will it cost hundreds of millions, even billions, yes, but the lives and injuries saved never mind the money and costs to NHS/police/fire on top of people on bikes not being driven at at ridiculous speeds will far outweigh the cost.

The amount of times I've given people living down my own street the hair dryer treatment for driving at speed is ridiculous, but I'll continue to do it and will continue to threaten to report them to the police if they continue to disrespect where I live and make it a less safe place for the families/kids who live here. 

20mph limits are only any good if there is enforcement and a zero tolerence approach by police and government as there should be for all speed limits. That we have a 10& + x mph before you will get a FPN is a reflection of how little governments give a shit about safety on our roads.

I think you have misunderstood the rule. You must use highlights at night. The exception is that in a road with street lighting (generally 30), this requirement does not apply.

I haven't misunderstood anything, I said built up areas which has street lights, read the rule again, it mentions nothing about you MUST use headlights in built up areas. It does say that side lights should be used, headlights particularly on modern day vehicles only add to the problem and are not necessary in urban conditons at night.

What you understand and what you wrote are not the same thing. You said you should not use headlights in a built up area which is not what the law says.

Sorry but you're wrong!

You MUST

•ensure all sidelights and rear registration plate lights are lit between sunset and sunrise
•use headlights at night, except on a road which has lit street lighting. These roads are generally restricted to a speed limit of 30 mph (48 km/h) unless otherwise specified.

Also the AA advise.

"Motorists must use sidelights between sunset and sunrise and headlights at night (between half an hour after sunset and half an hour before sunrise) on all roads without street lighting and on roads where the street lights are more than 185m apart or are not lit.

This implicitly implies that you MUST not use headlights on a road with street lighting, as I said, side lights are all you need. Just because everyone uses headlights and that police do nothing to curb this problem doesn't make it right or lawful. It's a major problem that you and most others ignore and thus the light 'war' has made safety on our roads only worse because of it. The European Union is also to blame with their disgusting enforcement of DRLs on motors.

Generally agree with the last bit but the first statement doesn't follow - "not must" isn't the same as "must not". There may be other guidance that says you should  not use headlights in those circumstances but what you've quoted above doesn't say that.

Agree - "You MUST do [X] except when [Y]" is not the same as "You MUST NOT do [X] when [Y]". The 'MUST' wording in the Highway Code is there to make clear which rules are legal requirements, the breach of which is a criminal offence. There are also examples of the use of 'MUST NOT' in the Code (including in the very next rule), but this is not one of them.   

If you carry on to rule 115 it adds: "You should also use dipped headlights, or dim-dip if fitted, at night in built-up areas and in dull daytime weather, to ensure that you can be seen".

So my reading of rules 113 and 115 together is that it's not a legal requirement to use headlights at night on roads with street lighting (you can just use sidelights), but use of headlights is still advised.

What really annoys me is the number of drivers I see with only their DRLs lit at night (so no rear lights on). As DRLs are so bright and modern dashboards seem to be permanently backlit, it seems many drivers are completely unaware that they're unlit at the rear - I've seen it on motorways as well as around town.

It does not imply that at all. Besides, the relevent legislation is The Road Vehicles Lighting Regulations 1989 and regulation 25 makes it clear that you do not have to use headlights in this situation, not that you must not.
