Smart motorway junctions 16 to 19 Improving journey time reliability Capacity An objective of smart motorways is to improve journey time reliability. To achieve this on the between junctions 16 and 19, we will be adding extra capacity by converting the hard shoulder to a permanent additional traffic lane. Improved traffic flow The number of respondents who felt that use of variable speed limits would improve traffic flow remained constant at 52% in 2012-2013 and 2013-2014.* *National Road Users Satisfaction Survey (NRUSS) Advanced Reports, 2012-2013 and 2013-2014 Vaiable speed limits We will also use variable mandatory speed limits to improve the flow of traffic at particularly busy periods of the day. You will find more information about these features on some of our exhibition boards.

Smart motorway junctions 16 to 19 Supporting economic growth Congestion costs the economy Congestion is estimated to cost the economy 2 billion per annum, with traffic levels forecast to grow 46 per cent by 2040. Highways England recognises that effective management of congestion is needed, together with smarter use of our motorway network. Encouraging investment A functional transport system is important to encourage economic growth. If our roads are congested it impacts on businesses and can discourage investment. Reducing congestion, removing major bottlenecks and improving journey time reliability will help businesses in the area to be more efficient. Significant benefits Smart motorways deliver significant benefits for the investment made because of the way they work. They have many advantages over conventional widening schemes, one of these being that for every 1.00 spent, 4.00 worth of economic benefits are expected. Reducing costs Smart motorways can be introduced without the need to take large amounts of land. They can also be delivered at up to 40 per cent cheaper than traditional widening schemes. We work closely with our supply chain to maximise efficiencies throughout the design and construction process. Smart motorways have been found to improve traffic fl ows and journey times
Smart motorway junctions 16 to 19 Environmental assessment Looking after the environment All of our construction works will be located within the existing highways boundary. The junctions 16 to 19 scheme has undertaken an environmental assessment that covers a range of topics including noise, air quality, ecology, cultural heritage, water quality, drainage and visual impacts on the landscape. The results are presented in the environmental assessment report. The overall conclusion of this report is that the environmental impact of the scheme is not significant. The full report is available on Highways England s junctions 16 to 19 scheme website. Ecology Surveys for protected species have been carried out. Great Crested Newts were identified within ponds adjacent to the scheme. To ensure their habitat and life cycle remains protected during construction, mitigation work will take place under a licence granted by Natural England. A number of badger setts have been identified within and around the highways boundary. Any works likely to disturb badgers will also be undertaken under a licence granted by Natural England. Noise We will be working to mitigate noise where possible. Consideration has been given to a range of measures such as the installation of noise barriers and environmental vegetation barriers, for example trees and shrubs. Resurfacing of the carriageway will be completed with low noise surfacing. This work will be completed as part of the construction programme for the scheme. Landscape and views Any changes to the visual landscape will be minimal for most residents. The project will be re-using existing road gantry signs and siting new signage away from residential properties where possible. Highways England contractors undertaking an environmental assessment
Smart motorway junctions 16 to 19 The evolution of smart motorways Conception The first controlled motorway opened on the M25 in 1995 and led to an improvement in traffic flow. It was the success of controlled motorways that led to the M42 between junctions 3a and 7 becoming the first section of our network to test hard shoulder running during peak periods in 2006 to increase capacity on the existing network. The use of the hard shoulder Data from the M42 showed a 22 per cent 1 improvement in journey times, with accidents reduced by 55.7 per cent 2. The schemes that followed on the, 2 and M4/M5 near Bristol operate as controlled motorways until busy periods when additional capacity is needed. Traffic is then directed to use the hard shoulder. All lane running Highways England then opened the next development of smart motorways on the M25 between junctions 23 to 25 and junctions 5 to 7. These feature all lane running: the permanent conversion of the hard shoulder to an extra traffic lane. The latest smart motorways feature four lanes open to traffic supported by variable mandatory speed technology and incident detection. Emergency refuge areas are spaced at regular intervals along the carriageway. 1 ATM Monitoring & Evaluation, 4-Lane Variable Mandatory Speed Limits 12 Month Report (Primary & Secondary Indicators), 30/6/15 2 M42 MM Monitoring & Evaluation Three Year Safety Review, 2011 Smart motorway emergency refuge area and superspan gantry showing speed limits (for illustrative purposes only)
Smart motorway junctions 16 to 19 The smart motorway Using technology to help you The design of smart motorways - all lane running is not fundamentally different to the existing road network that does not have a hard shoulder. However, it has the added advantage of providing technology to detect and monitor traffic flows on the network. This is coupled with messaging systems able to communicate instructions to drivers, such as lane closures or speed limits. When used together, they create a controlled environment that leads to safe and more reliable journeys with smoother traffic flows. new gantries new signals new CCTV cameras emergency refuge areas message signs low noise surfacing traffic monitoring loop sites signs concrete barriers under carriageway ducts technology ducting

Smart motorway junctions 16 to 19 Emergency refuge areas What if my vehicle breaks down As part of the smart motorway scheme on the we will be constructing new emergency refuge areas at regular intervals between junctions 16 and 19. Drivers whose vehicles break down should try to drive to the nearest emergency refuge area, exit slip road or Sandbach or Knutsford motorway service areas. If a vehicle breakdown occurs in a live lane we set signs and signals on the overhead gantries until assistance can reach the driver. Once in the emergency refuge area drivers are encouraged to use the emergency telephone which will automatically pinpoint their location to the Highways England Control Centre. Highway England can help you Depending on the situation the Control Centre operator can send a Highways England Traffic Officer or recovery vehicle to the driver, or advise the driver s recovery service. We have further information and advice on preventing breakdowns and what to do if your car breaks down on our network on the Highways England web site. Remember to use the emergency telephone as this automatically pinpoints your location
Smart motorway junctions 16 to 19 Variable mandatory speed limits Changing speed limit signs One of the key features of smart motorways is variable mandatory speed limits. These speed limits displayed on the motorway come into operation when traffic volumes increase and the sensors activate lower speeds. Reducing speed during peak demand decreases stop-start conditions and allows traffic to move smoothly. It s the law The variable mandatory speed limits are clearly displayed on signs mounted either above each lane of the carriageway or on verge mounted signs which are clearly visible. The introduction of variable mandatory speed limits requires legislation in the form of regulations made under Section 17(2) and (3) of the Road Traffic Regulation Act 1984. These regulations allow vehicle speeds to be controlled through the smart motorway scheme during periods of congestion. Super span gantry with speed limit signs MS4 with speed limit sign
Smart motorway junctions 16 to 19 Incident management Procedures for smart motorways Incidents can be detected by using traffic queue detection loops in the road surface that are linked to verge mounted CCTVs, or calls from the public via emergency roadside telephones and mobile telephones. Where appropriate, signs and signals will be set to clear an access route for emergency vehicles. The signs and signals can then be set to protect the incident and the back of the traffic queue. 1 Incident detection The Regional Control Centre continues to monitor traffic conditions throughout the duration of each incident to ensure that the signs and signals set remain appropriate to the conditions. The Regional Control Centre is responsible for setting signs and signals to facilitate the re-opening of the carriageway and the safe dispersal of trapped or congested traffic. 2 Emergency service on scene 3 Incident protection and clearing 4 Incident cleared and smart motorway re-opened
