Speed Limits) Bill Research and Information Service Bill Paper 27th February 2014 Des McKibbin Road Traffic (Speed Limits) Bill NIAR 928-13 This paper examines the provisions of the Road Traffic (Speed Limits) Bill Paper 19/15 27th February 2014 Research and Information Service briefings are compiled for the benefit of MLAs and their support staff. Authors are available to discuss the contents of these papers with Members and their staff but cannot advise members of the general public. We do, however, welcome written evidence that relates to our papers and this should be sent to the Research and Information Service, Northern Ireland Assembly, Room 139, Parliament Buildings, Belfast BT4 3XX or e-mailed to [email protected] NIAR 928-13 Bill Paper Key Points The principal objective of the Road Traffic (Speed Limits) Bill (the Bill) is to reduce the number of accidents and fatalities caused by road traffic collisions, by introducing a 20mph speed limit for residential roads. The Bill provides DRD/Roads Service with the flexibility to make orders specifying that certain roads are, or are not, ‘residential roads’. In so doing, the Department has to consider whether or not the road is in a predominantly residential area or is a major thoroughfare. In order to apply this exemption it is anticipated that DRD/Roads Service would have to assess the entire urban unclassified road network (4,291km) to establish the most appropriate speed limit i.e. should the new national 20mph speed limit be applied or are the conditions right for a 30mph limit to be retained. A period of two years following royal assent has been prescribed for the DRD to carry out a public awareness campaign to ensure the public are made aware of the implications of this legislation. Under the current speed limit framework there are three national speed limits: . 30 mph on street lit local roads (referred to as Restricted Roads); . 60 mph on single carriageway roads; and . 70 mph on dual carriageways and motorways. However, DRD/Roads Service has the flexibility to set local speed limits in situations where local needs and considerations deem it desirable for drivers to adopt a speed which is different from the respective national speed limit. The current guidance on setting local speed limits is supportive of the current default 30mph speed limit in urban areas as it represents “a balance between mobility and safety of road users, especially the more vulnerable groups.”1 However, local speed limits of 20mph are encouraged in situations where there is a particular risk to vulnerable road users. Currently Roads Service favours 20mph zones, supported by traffic calming measures as it is generally accepted that these have a greater impact on reducing average traffic speeds, than is the case when a signed-only 20mph limit is introduced. At present there are no permanent 20mph limits in Northern Ireland. However, the latest road safety strategy2 has committed to trialling the wider application of 20mph limits; currently four schemes are underway. These are being run by the DRD in co- operation with the PSNI, who have agreed to enforce the speed limit on selected roads. 1 DRD Roads Service (2010) Setting Local Speed Limits in Northern Ireland. DRD: Belfast 2 Northern Ireland Road Safety Strategy to 2020 [online] available from: http://nia1.me/1u6 Northern Ireland Assembly, Research and Information Service 1 NIAR 928-13 Bill Paper The Bill’s consultation was launched in May 2012; it sought views on a private member’s Bill that would bring about a reduction in speed limits from 30mph to 20mph on designated unclassified roads. The consultation attracted only 41 responses therefore it is unlikely that a representative geographic and/or demographic sample has been achieved. Overall the questionnaire appears to have been constructed in such a way to affirm the policy proposal: . Questions are leading i.e. they are worded in such a way that suggests the desired answer; . Respondents are asked to make judgements on society’s views rather than their own; and . It fails to ask the fundamental question of whether or not people are supportive of the proposed policy. The Department of the Environment’s consultation on Northern Ireland’s Road Safety Strategy to 2020 provides an alternative evidence base which gives some indication of local people’s views of 20mph speed limits and zones within Northern Ireland. This shows strong support for the wider use of 20mph speed limits particularly those without traffic calming measures. This consultation also suggests that the proposals in this Bill may not go far enough, in so far as there has been a call for the wider application of 20mph speed limits to include school areas, rural towns and villages as well as urban areas. Therefore, accommodating the wider use of 20mph limits (outside of restricted roads) is something which members may wish to consider during their scrutiny of the Bill.

In addition to road safety, the bills proposer also foresees indirect benefits to public health with greater numbers of people being encouraged to walk and cycle.3 A discussion on the impacts of 20 mph schemes on increased walking and cycling is provided in Research and Information Service publication NIAR 882-11.4 This paper considers: . The main provisions of the Bill; . The current speed limit framework in Northern Ireland; • Including the current approach to setting 20mph speed limits; . Plans for 20mph speed limits within the current Road Safety Strategy for Northern Ireland; and . The consultation conducted by the Bills proposer. 2 The Road Traffic (Speed Limits) Bill The Road Traffic (Speed Limits) Bill was introduced to the Assembly on the 9th December 2013. The Bill seeks to amend existing road traffic law pertaining to speed limits, specifically the Road Traffic Regulation (Northern Ireland) Order 1997. Specifically, the Bill, if enacted, will introduce a new national speed limit, of 20mph, on residential roads: 1. In Part VI of the Road Traffic Regulation (Northern Ireland) Order 1997 (speed limits) after Article 37 insert— “General speed limit on residential roads” 37A.—(1) Subject to the provisions of this Part, it shall not be lawful for any person to drive a motor vehicle on a residential road at a speed exceeding 20 miles per hour. A residential road refers to what is currently known as a restricted road, defined as: “a road which is provided with a system of street lighting furnished by means of lamps placed not more than 185m apart”.5 It is unclear from the bill if the new category of road is a replacement (for restricted roads) or an addition to current subcategories of road (table 1). 3 OFFICIAL REPORT (Hansard).

    Title: Impact Assessment (IA) Raising the speed limit for HGVs >7.5T on dual carriageway roads IA No: DfT00280 Date: 23/09/2014 Lead department or agency: Stage: Final Department for Transport Source of intervention: Domestic Other departments or agencies: Type of measure: Primary legislation None Contact for enquiries: [email protected] Summary: Intervention and Options RPC Opinion: EANCB Validated Cost of Preferred (or more likely) Option Total Net Present Business Net Net cost to business per In scope of One-In, Measure qualifies as Value Present Value year (EANCB on 2009 prices) Two-Out? £0m £0m £0m Yes Zero net cost What is the problem under consideration? Why is government intervention necessary? On dual carriageways the speed limit for HGVs>7.5T is 50 mph. The average actual speed at which these HGVs travel in free flow conditions (when they are not held up by other traffic or obstructions such as junctions, hills or bends) is about 53 mph (excludes rigid 2 axle HGVs)1. More than 80% of HGVs exceed 50 mph in free-flow conditions. The limit is out of date and systematically ignored by professional HGV drivers. The proposal is to raise the speed limit on dual carriageway roads for these vehicles to 60mph, which would better reflect the capabilities of modern HGVs. Government intervention is necessary because speed is regulated by government, through speed limits, in order to balance the private benefits of speed of travel with the social costs and risks (such as related to safety) of high speeds. What are the policy objectives and the intended effects? The intention is to modernise the speed limit, improve compliance, make the limit more credible and legitimise the behaviour of professional drivers.

  • Roundabouts Applying the 'System'
    Roundabouts Applying the 'System' to Roundabouts Let us suppose that you are on a dual carriageway approaching a roundabout (400m away). You are currently in the left lane and you intend to turn right at the roundabout. Information: - Take - You see the roundabout and its triangular warning signs in the distance. There are no vehicles between you and the roundabout but you see vehicles on the roundabout. Mirror check. There are two vehicles behind, both in the left lane. - Use - You know that you have to change to the right lane and that you will need to signal to change lane and then to signal continuously on the approach and through the roundabout (the standard Highway Code procedure for turning right at a roundabout)- Give - After checking your mirrors you signal right to the vehicles behind. Position: The right signal remains on for a few seconds and then gradually you move to the right hand lane (Information-Use/Give). When the manoeuver is complete you cancel the signal. After a few more seconds the right signal is re-applied to confirm to the drivers behind that you intend to turn right at the roundabout. Information: The speed and position of the vehicles behind are monitored as you approach the roundabout. An assessment is made of the movement of vehicles on the roundabout and those approaching it from the right and left. You look over the roundabout to see, if possible, vehicles approaching it from the opposite direction (Information-Take). Speed: As you approach the roundabout you begin to brake and lose speed smoothly and progressively (Information-Give).

  • TA 79/99 Amendment No 1 3
    Chapter 3 Volume 5 Section 1 Determination of Urban Road Capacity Part 3 TA 79/99 Amendment No 1 3. DETERMINATION OF URBAN ROAD CAPACITY 3.1 Table 1 sets out the types of Urban Roads and the features that distinguish between them and affect their traffic capacity. Tables 2 & 3 give the flow capacity for each road type described in Table 1. 3.2 Table 4 gives the adjustments when the proportion of heavy vehicles in a one way flow exceeds 15%. A heavy vehicle is defined in this context as OGV1, OGV2 or Buses and Coaches as given in the COBA Manual (DMRB 13.1 Part 4, Chapter 8). 3.3 The flows for road type UM in Table 2 apply to urban motorways where junctions are closely spaced giving weaving lengths of less than 1 kilometre. Urban motorways with layout and junction spacing similar to rural motorways can carry higher flows and TA46/97 “Traffic Flow Ranges for Use in the Assessment of New Rural Roads” will be more applicable. 3.4 Flows for single carriageways are based upon a 60/40 directional split in the flow. The one-way flows shown in Table 2 represent the busiest flow 60% figure. 3.5 The capacities shown apply to gradients of up to 5-6%. Special consideration should be made for steeper gradients, which would reduce capacity. 3.6 On-road parking reduces the effective road width and disrupts flow, e.g. where parking restrictions are not applied on road type UAP2 the flows are likely to be similar to UAP3 where unrestricted parking applies, see Table 1, Similarly effective parking restrictions can lead to higher flows.

  • The A19 Trunk Road
    THE CHARTERED INSTITUTION OF HIGHWAYS & TRANSPORTATION The A19 Trunk Road The A19 tends to live in the shadow of the more well known A1 it runs more or less parallel with. However, it is no less important to the region, serving the heavy industry and associated ports of Teesside, Wearside and Tyneside. Its journey from a single carriageway road linking coastal towns to modern day dual carriageway has been a painstaking process of over 45 years but has brought both economic and visual transformation to the North East. 1 A Broad History Today the A19 trunk road is a modern all-purpose dual carriageway running from the junction with the A1 at Seaton Burn, north of Newcastle, until it leaves the region south of Middlesbrough. It continues through North Yorkshire to Thirsk and, via a short link (A168), rejoins the A1 at Dishforth. The A19 itself continues as a non-trunk road to Doncaster. In 1952, the A19 was very different. It existed only south of the River Tyne and was a coastal route of single carriageway and relatively poor standard. Starting at South Shields it passed through Whitburn, Sunderland and Seaham, heading inland through Easington and then back out to the coast via Horden and onto Hartlepool. It then snaked its way through Billingham, Stockton, Eaglescliffe and Yarm. The improvements in our region towards the route we know today began at the Tyne Tunnel in 1967/8. The tunnel (£13.4m) was built with approach roads from the A1058 Newcastle to Tynemouth Coast Road (£6.5m) in the north and the A184 Gateshead to Sunderland Trunk Road (£3.5m) in the south.

  • Dual Carriageways Dual Carriageways – Know the Dangers
    ROAD SAFETY EDUCATION Dual Carriageways Dual carriageways – know the dangers Never confuse a dual carriageway with a motorway. Both may have 2 or 3 lanes, a central reservation and a national speed limit of 70 mph, but that’s as far as the similarity goes. When driving on a dual carriageway there are many dangers you need to be aware of. Know the difference between dual carriageways and motorways Unlike motorways… • Dual carriageways may have variable speed limits; • Dual carriageways usually permit right turns; • Dual carriageways allow traffic to join from the left and cross from left to right; • Cyclists, mopeds, farm vehicles and pedestrians are allowed to use dual carriageways; • Dual carriageways may have Pelican Crossings, traffic lights, roundabouts and Zebra Crossings. 2 Know the speed limits Dual carriageways often have lower or variable speed limits shown by red circular signs. Rule 124 of The Highway Code NI says you MUST NOT exceed the maximum speed limits for the road and for your vehicle. The presence of street lights generally means that there is a 30 mph (48 km/h) speed limit unless otherwise specified. 3 Know your stopping distances (Rule 126) Always drive at a speed that will allow you to stop well within the distance you can see to be clear. Leave enough space between you and the vehicle in front so that you can pull up safely if it suddenly slows down or stops. Remember - • Never get closer than the overall stopping distance (see typical stopping distances table); • Always allow at least a two-second gap between you and the vehicle Know how to join a in front on roads carrying dual carriageway fast-moving traffic and in tunnels where visibility is reduced; When joining a dual carriageway • The two-second gap rule should obey signs and road markings.

References/Bibliography Appendix A Key pieces of speed limit, signing and related legislation and regulations SECTION 1: INTRODUCTION Key points Speed limits should be evidence-led and self-explaining and seek to reinforce people's assessment of what is a safe speed to travel. They should encourage self-compliance. Speed limits should be seen by drivers as the maximum rather than a target speed. Traffic authorities set local speed limits in situations where local needs and conditions suggest a speed limit which is lower than the national speed limit. This guidance is to be used for setting all local speed limits on single and dual carriageway roads in both urban and rural areas. This guidance should also be used as the basis for assessments of local speed limits, for developing route management strategies and for developing the speed management strategies which can be included in Local Transport Plans. 1. The Department for Transport has a vision for a transport system that is an engine for economic growth, but one that is also more sustainable, safer, and improves quality of life in our communities.

  • The UK Standards for Roundabouts and Mini Roundabouts
    THE UK STANDARDS FOR ROUNDABOUTS AND MINI-ROUNDABOUTS Janet V Kennedy Transport Research Laboratory (TRL) Crowthorne House Nine Mile Ride Wokingham Berkshire RG40 3GA United Kingdom Tel +44 (0) 1344 770953 Email [email protected] ABSTRACT The modern priority rule for roundabouts was first introduced in the UK during the 1960s and has been in widespread use ever since, gradually being adopted around the world. Roundabouts are recognised as a safe and efficient form of junction, particularly where side road flows are high. Extensive research led to predictive models for both safety and capacity and modern design is based on these relationships. The idea of mini-roundabouts was conceived during the 1970s. They are used in the UK in urban areas where a roundabout would be the first choice of junction if space permitted. They usually replace existing priority junctions. Like conventional roundabouts, they are seen as a safe and efficient form of junction. Both capacity and accident predictive relationships have been developed specifically for mini-roundabouts. The new standards for the geometric design of roundabouts and mini-roundabouts were published in 2007. Details of both standards are given in the paper.
