Road Humps and 20 mph Speed Limits

Debate between Gregory Campbell and Iain Duncan Smith

Tuesday 5th December 2023 Westminster Hall

[Sir Iain Duncan Smith]

I very much accept that point. I am grateful for my hon. Friend’s intervention, because I was going to come to that issue. It is not an issue particular to London, but in London we have the problem that traffic-calming measures are causing higher emissions in parts of the city where the measures are applied, and at the same time traffic is being funnelled with no escape routes.

We also need to take into consideration the increase in noise pollution during the day. Conversations are being drowned out in many houses near the humps, and the effect of the additional noise on residents living in the vicinity of a hump—not forgetting that the traffic goes up and down such roads all through the night—is that sleep is disturbed.

I have been in a number of houses and have stood and watched as commercial vehicles have gone over large 20 mph tables. I could hear the equipment in the back leaping up and down and the thump as the vehicles hit the tables—and they were not going over the speed limit. That is the point. When I have raised it with the council, it has dismissed it completely on the basis that it does not agree that the measures cause any problem whatever. The effects of additional noise on residents living in the vicinity include disturbed sleep and the stress resulting from sleep deprivation.

[Mr Gregory Campbell (East Londonderry) (DUP)]

I congratulate the right hon. Gentleman on securing the debate. Does he agree that another issue arises when road traffic-calming measures have been put in place where there are suitable diversionary routes for some motorists to avoid the speed humps and traffic-calming measures? There is increased traffic on those roads as a result. People complain on the routes where the humps are, but people living on adjacent roads also complain because of the increased traffic that has resulted from the humps.

[Sir Iain Duncan Smith]

Yes, I agree. The funny thing, which I raised the other day, is that if we are moving towards low-emission or zero-emission vehicles, electric vehicles, hydrogen-propelled vehicles and so on, which is the generally accepted plan for where we want to be, are we now aiming for road usage by low or net zero vehicles, or is it just a blanket anti-car problem? That is an issue that I never settle. In a way, we will be defeating ourselves as we head towards that process. Will the measures be lifted as more people have zero-emission vehicles?

The question is: why are the speed humps there? They are there, in essence, because in areas where they are necessary, no one objects to the idea of proportionate use. However, when they are combined with low-traffic neighbourhoods, it becomes a major problem. People are forced on to roads, which means that the poor residents who live near them get even further increased levels of noise pollution, vibration and brake pad wear. That is toxic anyway, and is made more so than if those drivers had been able to use other routes to get out of those areas.

I return to the point about disturbed sleep. I have talked to residents who are genuinely deeply stressed by what has happened since heavy speed bumps have been put in place in 20 mph or even higher speed zones. As for the effects on the public’s mental health, some residents now genuinely suffer from some kind of clinical depression.

There is also damage to people travelling in vehicles, including buses, that traverse humps. Even if someone is doing less than 20 mph, they hit those things and they know it. For cyclists and others, as I mentioned, that is a major issue. I happen to be a motorcycle rider, and I must say that there are significant problems. Some of the tables are so high that riders have to stand up off the bike, making it less manoeuvrable. I have some sympathy for all those other road users, whom we rather forget about but whom we are encouraging to use those methods of travel more because they pollute less or not at all.

Research has been undertaken with bus drivers on the effects on their health of the constant impact damage on the spine and neck from the rocking motion. If we are asking for more buses and more public transport, we should recognise that those are bigger vehicles, and the effect on them and on neighbourhoods is significant.

Let me move on to the damage done to vehicles as a result of poor maintenance and the design of speed hump installations. In my borough, speed humps and calming measures on residential roads are the responsibility of the local authority, as they are everywhere else. The humps in the London Borough of Waltham Forest have been poorly maintained, with road surfaces on the exits dipping because of the impact of vehicles. Along with the scrape marks on the crown of the hump, which give some indication of the existing problem, vehicles grounding on the top of the humps when passing over them would suggest that those humps are not really fit for the purpose originally intended.

The authority installed the speed humps because of research generated by the Transport and Road Research Laboratory in 1981 and 1990, but the research data in those reports, astonishingly, dates back to 1958, the 1960s and at the latest the 1970s. That is my main point about the whole process: it uses data that is completely unrelated to traffic use today, the nature of cars, the size of vehicles and all the consequences. We rely on data that does not encompass any of that or the change in how cars and vehicles are used.

The old research data—on which my local authority and, I am sure, others rely heavily—was gathered using one double decker bus on a small section of one road in Lytham in Lancashire in 1977, where buses were scheduled to run once every 30 minutes. We then have data from 1978 from a small section of one 302-metre road in Winchester, which had only three houses on it, and one 438-metre road on the Isle of Wight. It cannot be fair or right that there is a blanket rejection of all concerns, as is happening in my local authority area, which refuses to look at the matter carefully because it says that its measures are based on studies. Those studies are irrelevant to traffic usage today.

The final study, which really threw me, looked at a 280-metre road in Rotherhithe, comprising very few houses. That was in 1978. I am not quite sure what they were studying at the time, but it certainly has nothing to do with my constituency or borough. This is not a Labour or Conservative issue; it is about residents and citizens who live in such areas trying to get to work and use their cars for different reasons. We need to consider the wider consequences.

None of the research data or reports is therefore relevant to east London or to 21st-century traffic. The traffic in the 1960s and 1970s was very different from today’s: the dramatic increase in the volume, frequency and weight of all traffic, especially heavy goods vehicles and electric vehicles, means that it is not comparable with the data that is now being used to justify what is going on. To date, the council has not conducted an investigation of speed tables in my constituency or borough. It simply rejects the idea that it should do so or that there should be an independent study.

In October, councillors—they happen to be my Conservative group—proposed a motion that called on the local authority to carry out an independent review simply to monitor suspected vibrations and the nature of the traffic-calming measures. It was rejected out of hand. Unfortunately, there was no other recourse. That is why I secured this debate: it seems that there is no other way for my local councillors or me to raise the issue. My residents, regardless of where they live, are frustrated and unable to find any other recourse.

I ask the Minister: what are the consequences for a council that fails to comply with the statement contained in the Department for Transport’s letter dated 26 April 2023? It states:

“Local councillors are responsible for ensuring that local decisions about street infrastructure take account of the needs and opinions of local people.”

That is simply not happening. It is a wider issue. It does not matter whether it is a Conservative or Labour council; that statement is being thrust to one side in the desire to put the calming measures, as they are called, in place.

I want to quote from one or two of my residents who have raised the matter, because it is important. Tony Thorne said:

“My wife suffers with arthritis of the spine and we recently had cause to travel in Waltham Forest going to visit our son in Whipps Cross Hospital and when we got home she wanted to cry with the pain”,

as a result of the constant jerking. He goes on:

“We now have to plan our journeys to avoid certain areas due to the speed humps which even when you travel over them at 10 mph there are still problems with the bounce on exit.”

I have seen that for myself, by the way. He goes on:

“I have spoken to a number of bus drivers who drive the roads of Waltham Forest who all mention the problems these obstructions cause including drivers being off work sick with back and neck pain and additional stress due to having to negotiate these structures.”

Lee Gilbert said:

“We suffer sleep deprivation and I suffer from anxiety and fear that the movements may cause the house to collapse whilst in bed. There are 20 mph signs although they are not adhered to. We have been trying to seek a solution to this major problem since the Speed Hump was installed in July 2022 with no results.”

Tracey Gauld said:

“I was injured when my car was hit by a drunk driver which left me requiring surgery on my collar bone. Still to this day, going over humps is uncomfortable due to the seat belt”.

Andrew Mckinley said:

“Since the speed humps have been installed outside my house, I have not had a full night’s quality sleep…I do believe in a safer and clearer environment for all. I would normally cycle 12 miles to work each day but have been unable to do so as it would be unsafe as I’m very tired due to lack of sleep. This is having a big negative impact on my mental and physical wellbeing”.

Finally, Adam Thackeray said:

“Since a speed bump has been installed on Station Road”—

that is in my constituency—

“my house judders when busses and large vehicles go past. The house, mainly the top two floors shake, the windows vibrate, and this has resulted in cracks appearing around the house on various walls, with the top floor suffering the most. It’s also difficult to get to sleep on the top floor, due to the vibrations causing furniture to rattle and sash windows shake”.

To some people, those issues may appear unimportant, but if we are elected to do anything at all, it is to represent the concerns and interests of our constituents when they spot a significant problem that affects their lives. That is why I make no apology for raising the matter. It is not a minor issue. It is becoming a significant issue where these things have often been imposed without any proper discussion or any sense of what is required on our streets and what the issues are in respect of traffic calming and speed.

As things stand, the Mayor of London provides funding to boroughs for the implementation of traffic-calming measures. I have been assured that, if successful, the new Mayor after the mayoral contest will ask the boroughs to ensure that all measures are examined so that the most appropriate are put in place; implement a review of all Transport for London-owned roads that have 20 mph speed limits; and, where appropriate, make changes. That is a natural position to take. I hope that the present Mayor of London will adopt the same policy, because it is clear that people living in houses near traffic- calming measures and people who drive public transport are suffering unnecessarily.

I am calling on the Department for Transport to carry out, where local authorities and others will not do so, a full independent inquiry to review roads with 20 mph speed limits, on a road-by-road basis, and to consider the impact of traffic-calming measures such as road humps and the speed tables that are even higher. Such a review could help to limit the unintended consequences of vibrations from ill-applied traffic-calming measures by finding out relevant information and up-to-date data.

I remind the Minister and others that the Department for Transport has made it clear that any changes to the speed limits and to traffic-calming measures should be proportionate and based on circumstances. Right now, there is no up-to-date independent review of how such measures should be applied, and no up-to-date independent analysis of what the effects are. The council in my area is therefore able to dismiss all requests for independent reviews. My residents, and residents all over the country, would feel better assured if the Department for Transport carried out a review to get the matter properly settled so that we can bring peace of mind to residents whose lives are being disproportionately damaged by bad implementation and ill-thought-through traffic-calming measures.
