Managed Motorway Scheme (South Yorkshire)

Debate between Meg Munn and Paul Blomfield

Wednesday 6th March 2013 Westminster Hall

[Meg Munn (Sheffield, Heeley) (Lab/Co-op)]

I am pleased to have secured today’s debate on the managed motorway scheme consultation for the M1, between junctions 32 and 35a. The consultation that could have such fundamental consequences for the safety of motorists on this section of the M1 was just eight weeks long over the Christmas period.

The Highways Agency’s proposals recommend the implementation of variable mandatory speed limits between junctions 32 to 35a, which is a section of motorway around the city of Sheffield. The section carries around 110,000 vehicles per day, and is congested during the weekday morning and evening peak hours and, like all roads, at other times.

The consultation document recommends that variable speed limits should be set in response to traffic conditions, automatically calculated from sensors buried in the road. Speed limits would be displayed on the motorway indicator signs above lanes, mounted on existing overhead gantries, and on additional verge-mounted signs. Where no speed limit is displayed, the national speed limit would be in force. However, the proposals, unlike other managed motorway schemes, include the use of the hard shoulder 24 hours a day, seven days a week. Emergency refuge areas would be created at intervals of a maximum of 2,500 metres, and would include emergency telephones. All other telephones would be removed from the hard shoulder, as it would in effect become a permanent fourth lane.

I thank my hon. Friend for giving way, as I wanted to have the opportunity to intervene on the issue of refuge areas. I note that the Highways Agency website refers to the emergency refuge areas that will be in operation, saying that they will provide

“an area of relative safety”.

Is she satisfied with the concept of “relative safety”, and does she hope that the Minister, in his response to the debate, will define what that means?

[Meg Munn]

My hon. Friend makes an important point about “relative safety”. There are lots of concerns about “relative safety”. Having driven down the M1 on Sunday and having looked at refuge areas in other managed motorway areas, it concerns me that “relative safety” is not equivalent to the kind of safety that we expect for people on the edge of motorways.

The consultation document suggests that the benefits would lead to an increase in motorway capacity and reduced congestion; smoother traffic flows; more reliable journey times; an increase and improvement to the quality of information for the driver; and lower costs and less environmental impact than conventional widening programmes. In effect, the Highways Agency is suggesting that this proposal is the best solution to add capacity to the existing strategic road network. It claims that these benefits can only be achieved by the use of variable mandatory speed limits and the use of the hard shoulder as an additional lane 24 hours a day, seven days a week. I do not agree with all the recommendations, and I challenge some of the argumentation set out in the proposals. Worryingly, there is no objective to increase road safety on this section of the motorway, which I would have thought should have been a priority.

Managed motorway schemes have been introduced elsewhere, notably on the M6 and M42. As I said earlier, schemes on those motorways differ from the proposals for the section of the M1 that I am discussing. Other schemes have only been introduced at peak flow times—weekday morning and evening rush hours—and with the overhead gantries spaced at 500 metres. The hard shoulder then reverts to just that—a hard shoulder—when congestion is not an issue. Evidence suggests that the introduction of a managed motorway scheme on those motorways has indeed led to a reduction in congestion and an improvement in traffic flows, resulting in fewer accidents and more reliable journey times.

In response to a parliamentary question that I asked, the Minister said:

“The safety risk analysis of all lanes…of the M42… showed that the average number of personal injury accidents reduced from 5.08 per month…to 2.25 per month following the introduction of hard shoulder running.”—[Official Report, 14 February 2013; Vol. 558, c. 846W.]

That is a statistic for which the Highways Agency should be applauded, but my concern is about the very different proposals for the M1. The two schemes are not directly comparable and it is misleading to suggest, both in the consultation documents and in the reply to my parliamentary question, that they are. What is different, and what has not been taken fully into account, is the issue of hard shoulder running for 24 hours, seven days a week. I am particularly concerned that this part of the proposal, if it is adopted, would have a detrimental impact on safety and the ability of the emergency services to respond to major incidents.

It is in non-peak times that accidents are most likely to occur, a situation that could potentially be aggravated by poor visibility. The detection of a stranded vehicle would be very difficult unless CCTV cameras are constantly monitored, and as I understand it the electronic detection system will only activate when traffic slows and therefore it would do little to warn approaching drivers.
