Planning for Walking

Read document description

This Chartered Institution of Highways and Transportation (CIHT) guideline Planning for Walking: • describes the characteristics of pedestrian journeys, • lists the benefits of walking, • identifies factors that discourage walking and how they can be overcome, • summarises the legal framework that applies to pedestrians and • outlines the way that plans and strategies for pedestrian travel are developed. As it is a web-based publication that can be modified relatively easily, CIHT would welcome examples that build on the content of this guidance for inclusion in further guidance on the subject. These guidelines are complemented by another CIHT document, Designing for Walking (CIHT, 2015), which covers the design and evaluation of facilities for pedestrians

Planning for Cycling

Read document description

Cycling is an important part of urban transport. However, for many years its role has been neglected in the UK, with the focus mainly on the needs of motor traffic. Cycling is one of the most sustainable forms of transport, and increasing its use has great potential. To release this potential, highways, public spaces and other rights-of-way need to be organised accordingly. Planning for cycling is discussed in these guidelines; detailed design of infrastructure and facilities for cycle users will be examined elsewhere.

Surface Dressing Code of Practice

Read document description

This sixth edition of the Code of Practice has been produced by the RSTA Surface Dressing Technical Committee. It has been reviewed in the context of the European Standard for Surface Dressing BS EN 12271 published in September 2006 along with the national guidance document PD6689:2009. This document has been peer reviewed by ADEPT Soils, Materials, Design and Specifications Committee. To the highway engineer, surface dressing offers a quick, efficient and cost-effective way of maintaining skid-resistant and waterproofing road surfaces. To obtain the best results it is necessary to give careful consideration to a wide range of detail and to plan and design the work carefully. The speed of the surface dressing operation and the short duration of time during which motorists are inconvenienced is also an important issue. The purposes of surface dressing are to waterproof the road surface, to arrest disintegration, to provide texture, and provide a skid-resistant surface. This latter quality can play a major part in accident reduction and was highlighted by the initiative of the Department of Transport in 1987 when the Minister introduced minimum mean summer SFC values for motorways and trunk roads. The importance of surface texture as provided by surface dressing has been highlighted by TRL report LR 286, which stresses that texture depth is important under both wet and dry conditions. Up to date guidance is available in the Design Manual for Roads & Bridges (DMRB): Volume 7 HD 28. The DMRB is available on line at A useful way of comparing the effectiveness of a dressing, or other maintenance work, is to express it in terms of a ‘cost life index’. This is the cost per square metre of the work divided by the service life in years. It provides a measure of the “value for money” which the highway authority is achieving. A low ‘cost life index’ and “high value for money” is the result of high-quality work. The purpose of this Code is to identify the important aspects of the process, and to refer to other documents relating to good surface dressing practice and so give practical guidance on achieving high quality.

Traffic Signs Manual Chapter 4: Warning Signs (2013)

Read document description

2013 UPDATE - Through the Traffic Signs Manual, the Department for Transport provides guidance to traffic authorities and sign designers on good practice in respect of the design and use of traffic signs in order to provide appropriate and adequate information for road users. The Manual is published by TSO as a number of discrete chapters each of which deals with a specific signing topic. We have made changes to Chapter 4 to bring it up to date following the amendments that were made to the Traffic Signs Regulations and General Directions 2002. Chapter 4 of the Manual is concerned with signs that warn road users of hazards ahead and was last updated in 2008. The main changes relate to the signing of low bridges and on using the new triangular warning sign that indicates maximum height in both imperial and metric units. Bridge strikes, where vehicles, their loads or equipment collide with bridges, are a significant and recurring problem and the revised guidance gives highway authorities up to date information and demonstrates the Department’s ongoing commitment to tackling the risk.

Guidance on the Design, Assessment and Strengthening of Masonry Parapets on Highway

Read document description

Masonry parapets are designed to provide protection for road users. This guidance document is designed to bring up to date previous advice on the design, assessment and strengthening of masonry parapets, drawing together guidance previously available in BS 6779:1999 Part 4 and in research papers, and bringing the terminology used in line with that used in BS EN 1317-2:1998 and BS EN 1996-1-1:2005

Delivery of Local Road Safety

Read document description

The Department for Transport commissioned AECOM, in association with the Tavistock Institute, to design and deliver a three-year independent evaluation of the delivery of local road user safety. The evaluation was commissioned to consider the following objectives: •to evaluate the different strategies and plans for delivering road user safety; •to assess what is being delivered, the key processes and how efficient local authority practices are; and •to identify lessons and areas of good practice in road user safety investment.

Management of Highway Structures Complementary Guidance

Read document description

Management of Highway Structures: A Code of Practice was published in September 2005. Since then Government Policy in respect to highway and structures management has developed and evolved in a number of areas, including the introduction of new statutory duties on highways authorities. There have also been developments/advances with regard to recognised good practice. To assist users of the Code, the Roads Liaison Group has prepared this complementary guidance which takes account of these changes and developments. Where appropriate, the complementary guidance provides details of where to find up-to-date information that can assist with the implementation of the good practice set out in the Code. Users of the Code should treat this complementary guidance as up-to-date and having the same status as the Code. Where paragraphs have been amended, they supersede the ones in the Code.

TRL PPR 530 Visualisation and display of automated bridge inspection results

Read document description

The research described in this report is the fifth stage of an ongoing programme of research with the objective of developing a more objective and repeatable bridge inspection procedure than the current system of manual inspections. The proposed inspection procedure is based on the collection and processing of images of structures to identify defects in highway structures. The research has been funded by, and performed on behalf of, the Transport Research Foundation (TRF). This report describes changes to the image collection system, including the inclusion of a robotic mount system. This requires very little human input other than to perform a brief calibration to determine the camera field of view, and the extent of the scene to be imaged. This dramatically speeds up the image collection procedure which was previously very labour intensive. Possible changes to the manner in which the data is presented to the end user are also described. The use of 3-D modelling and display techniques is discussed, and several pieces of proprietary software are investigated. These software packages can manipulate and display LIDAR data. This data can be converted into 3-D models of the bridge. The 3-D bridge model can be further enhanced by texturing, using the high resolution images collected by the imaging system. The report also discusses the use of a web-based service which takes multiple images of a scene and uses these to create a 3-D model of the scene or object which was imaged. The advantages and disadvantages of using the web-based system as a key part of the inspection regime are discussed. The report concludes by outlining the key components required for a successful automated bridge inspection system based on images, which could provide inspection data at a level comparable to that currently provided by a standard Highways Agency General Inspection.
