Impact Assessment
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 The limit is out of date and systematically ignored by professional HGV drivers.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. -

Waterford Bypass
ENGINEERS IRELAND WATERFORD BYPASS WATERFORD BYPASS JOHN T. MURPHY, BE, CEng, FIEI, HDipMM, RConsEI Project Director, Mott MacDonald Ireland JOE SHINKWIN, BE, CEng, MIEI, DipMechEng Project Manager, Mott MacDonald Ireland Presented to a meeting of the Cork Region of Engineers Ireland 23rd February 2010 SYNOPSIS The N25 Waterford Bypass comprises a 16.3 km of dual carriageway bypass of Waterford City, 9.5 km of major link roads and an additional 13 km of side roads. It includes a 465 metre long dual carriageway cable-stayed bridge over the River Suir (with a 230m main span), plus a number of major viaduct and grade separated interchange structures totalling over 50 bridges. This paper describes the development of the current route for the N25 Waterford Bypass including the various phases of route selection. It deals with the project’s inclusion as a pilot PPP project and the development of the PPP contract. It follows the project through the statutory processes (including the discovery of Viking remains and the need to find a new route around the designated national monument site in Woodstown). The paper also describes the selection of the chosen bridge type for the Suir River Crossing and looks at some of the other major structures. Finally, the paper will briefly describe the construction contract and various aspects of construction. 1 MURPHY and SHINKWIN INTRODUCTION crossing of the Suir in the Waterford viii) were evaluated without area would impose costs on, and quantification while items v), vi), and vii) The need for a second river crossing of produce benefits for, the community at were derived in the process of the the River Suir in Waterford has been large. -
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. -

Burren Signage Plan
Burren Signage Plan A report commissioned by Burren Connect, a project funded by Fáilte Ireland, in partnership with Clare County Council, Shannon Development, National Parks & Wildlife Service, National Monuments Service and Burren Beo.. BURREN SIGNAGE PLAN Executive Summary The Burren Signage Plan is a component of the Burren Connect Project, a multi- agency tourism development project for the Burren. Field surveys and a public consultation programme were carried out during May and June of 2007. The signage plan is based on a set of fourteen principles that emerged from consultation, assessments of the Burren landscape and a review of practice elsewhere. The plan recommends that signage in the Burren countryside is kept to a minimum in recognition of the exceptional quality of the landscape. It recommends that primary reliance for navigation is placed on the standard directional road signs, which are in the process of being upgraded on all the national and regional roads in North Clare. The plan considers that there is a place for visitor signage in the Burren, but that signage and visitor information in general should, as far as possible, be concentrated in and near existing villages, at major junctions and at the larger established visitor sites. The plan recommends caution in deploying signage for new recreation initiatives such as looped walks and cycle routes in the remoter areas of the Burren. The Burren does not lend itself to precise geographical definition but a signage plan has to enable drivers and other visitors to be able to answer the question ‘Are we there yet?’ The plan recommends adopting the settlements that ring the area as boundary markers.
