Noise management and abatement     0 2293 15.06.2010
  Noise is an important factor to be considered when it comes to developing, upgrading, and maintaining national road networks in Europe. Examples of such activities are included in this report. In some EU member states, significant financial resources are used to incorporate noise abatement measures into the development or upgrading of national roads. Therefore, there is a need to optimise and improve the way such resources are used. One way to ensure this is to encourage member states to sha ...[more]
Gestion et Reduction du Bruit     0 2130 06.07.2010
  Le bruit est un facteur important à prendre en compte au moment de développer, de remettre à niveau et d’entretenir les réseaux de routes nationales en Europe. Des exemples des activités précitées figurent dans le présent rapport. Certains États membres de l’UE mobilisent des ressources financières importantes pour intégrer des dispositifs de réduction du bruit dans le développement et la modernisation de leurs routes nationales. Il est par conséquent nécessa ...[more]
Shoulder & Median Rumble Street     0 2051 06.07.2010

Member states were asked to answer the following questions: - Is there a regulation that governs the safe distance between vehicles in your country? - If so, what are the rules (e.g. leave at least 2 seconds following distance to the vehicle in front)? 􀂾 Have you experienced any problems enforcing these rules? This ...[more]
Longer and/or Longer and Heavier Goods Vehicles (LHVs) a Study of the Effects if Permitted in the UK: Final Report     4 2315 15.06.2010
  Goods vehicles that are longer and/or longer and heavier (abbreviated as LHVs in this report) than those currently permitted in the UK are in use, under trial, or being considered, in a number of countries both within the European Union (EU) and elsewhere. The European legislation that controls the maximum dimensions of vehicles, and the maximum weight that guarantees free circulation within the EU, permits trials and the use of these vehicles under certain strict conditions. The legislation is ...[more]
Models for Permanent Deformation for Bituminous Bound Materials in Flexible Pavement (SAMARIS)     0 4232 04.05.2011
  This report deals with models for the prediction of permanent deformation behaviour of bituminous materials. In regard to the aim of the pavement stream of the SAMARIS project - to encourage the use of recycled and secondary materials in pavements by detailing how such materials shall be selected and tested in order to secure satisfactory performance, environmentally as well as functionally – it has to be pointed out that the models described in the present report are applicable for conven ...[more]
Results of a field study on a driver distraction warning system     0 3553 02.02.2010

This report focuses on the findings concerning driver distraction. Seven participants used the car just as their own car during a period of one month each. During the baseline phase, which comprised of the first ten days of the trial the distraction warnings were deactivated. During the treatment phase, consisting of the remaining 20 day ...[more]
Night-time traffic in urban areas - A literature review on road user aspects     0 4343 18.04.2011
  Human vision is not well adapted to night-time conditions. Hence, road users need technical solutions, such as street lighting and retroreflective materials, in order to be able to drive, cycle or walk safe at night. Night-time traffic implies some certain problems, for example glare and difficulties with detecting obstacles and estimating distances. Different groups of road users have different prerequisites and needs, and the problems encountered may thus vary. In order to improve traffic safe ...[more]
Transport effects of IMO's more stringent emission reguirements – Model calculations on behalf of the Swedish Maritime Administration     0 3269 23.07.2009
  The Swedish Government has commissioned the Swedish Maritime Administration to assess the consequences of the new rules for airborne emissions of sulphur dioxide and nitrogen oxides from maritime transport, adopted by the International Maritime Organization (IMO) in October 2008. On behalf of the Swedish Maritime Administration, the Swedish National Road and Transport Research Institute (VTI) has shed light on whether the IMO’s more stringent emission requirements in the SOx Emission Control ...[more]
