Permit scheme – decision making and development

Read document description

This short guidance note on Permit Schemes is aimed at English local highway authorities, and provides tips and suggestions on scheme development and application practicalities. It reflects experience and lessons learned during the development and approval of the first schemes, and should be read in conjunction with, other Department for Transport (DfT) guidance documents giving more detailed advice.

Driver reaction times to familiar but unexpected events

Read document description

The Driver Reaction Times to Familiar but Unexpected Events study was undertaken as part of the TRL re-investment program to promote internal research. The study was designed to take advantage of existing data collected during previous trials in the CARSIM, together with bespoke studies designed to be integrated into new trials. In collision investigation, it is the perception and response of a driver to a familiar, but unexpected event (such as the sudden movement of a pedestrian crossing from behind a parked vehicle) that is of considerable importance when reconstructing an incident for criminal or civil proceedings. The reaction times measured in the trials in this TRL study, appear to be consistent with the work of Olson, partially because of the nature of the definition of Olson’s reaction time range. Instead of taking the range as fixed, the collision investigator needs to understand how the range was calculated and whether a particular event needs the range to be modified, such as when the detection and identification phases may have been undertaken before a particular hazard enters the road.

Effect of 20 mph traffic speed zones on road injuries in London, 1986-2006: controlled interrupted time series analysis

Read document description

Objective To quantify the effect of the introduction of 20 mph (32 km an hour) traffic speed zones on road collisions, injuries, and fatalities in London. Design Observational study based on analysis of geographically coded police data on road casualties, 1986-2006. Analyses were made of longitudinal changes in counts of road injuries within each of 119 029 road segments with at least one casualty with conditional fixed effects Poisson models. Estimates of the effect of introducing 20 mph zones on casualties within those zones and in adjacent areas were adjusted for the underlying downward trend in traffic casualties

Road Pricing - Update (2008-2009)

Read document description

This issue of Current Topics includes over 75 abstracts of reports, conference papers, books and journal articles which focus on the use of road pricing to manage traffic demand and to reduce the environmental impact of road traffic. Amongst the specific topics covered are charging principles (e.g. time, distance, congestion levels) methods of payment, modelling the effects of road pricing, driver response to road pricing and technological solutions. Road pricing in London, the results of the Stockholm trial and pilot schemes in the USA are discussed. These items have been selected from the material added to the Transport Research Laboratory's Library Database between 2008 and 2009. Much of the relevant English language published literature from the UK, USA, Australia and Europe is included; some of the non-UK literature is included courtesy of the OECD International Transport Research Documentation (ITRD) database.

UTMC Survey 2009

Read document description

Launched in 1997, the UTMC programme was the UK Department for Transport’s (DfT) main initiative for the development of a more open approach to Intelligent Transport Systems (ITS) in urban areas. Since its launch, UTMC has helped local authorities achieve their goals by adopting an appropriate, but not over constraining, set of standards to allow users, suppliers and integrators of UTMC systems to plan and supply systems cost-effectively in an open market. This UTMC Survey, therefore, addresses the deployment of traffic management technologies across the UK. It also looks at plans for the future and issues which have arisen in migrating to UTMC technologies.

Strategy for Lorry Parking Provision in England

Read document description

DfT understands that the provision of lorry parking facilities is a vital service that supports the national and international road freight operations which help facilitate the UK economy and its growth. Lorry parks help to ensure road safety, preserve local amenity, reduce opportunities for crime and address the general needs of HGV driver working conditions. It is therefore important such services have support on a national level that helps create an environment which reduces the current barriers hampering development, financial stability and adequate standards. To work towards this better environment for lorry parking a clear plan has to be in place that can be realistically and practically delivered. Creating this strategy for lorry parking is the first step towards a long-term solution. The strategy is also a response to the call from industry for a co-ordinated approach to policy.

Lorry Parking Baseline Report - Understanding the Current Situation

Read document description

The Department for Transport (DfT) is the policy lead on lorry parking and associated rest areas. The DfT are conscious that the provision of lorry parking facilities in England is often considered inadequate, by a variety of stakeholders, including lorry drivers themselves, their managers, other road users, associations, councils and residents of areas where lorries frequently park. This report will outline the current situation of lorry parking and its associated issues. This is to be used as a baseline document underpinning the development of a strategy / action plan for lorry parking provision in England.

DfT Shared Space project - Stage 1: Appraisal of shared space

Read document description

This report sets out the findings of an appraisal into shared space. It concludes that shared space schemes appear to be beneficial in appropriate settings, and that from the data available, there is no evidence that shared space schemes, including those with shared surfaces, as implemented in the UK have more casualties than conventional layouts, or that particular groups, including disabled people, are injured more frequently following their introduction.

The management and impact of abnormal loads

Read document description

Congestion on Britain’s roads is an increasing problem. The movement of large and heavy abnormal indivisible loads (AILs) through the road network can cause additional delays to other traffic. Delays caused by AILs could potentially be reduced by management measures based on a better understanding of how they are related to the types of load and the conditions under which the loads are moved. This Insight Report covers several projects that have investigated the prevalence and congestion impact of AILs and the effect of mitigation measures such as movement by water or by night. It concludes, however, that the overall impact of AILs on network delay is small and mitigation measures will be most effective if selectively targeted
