Revision of criteria for selection of road lighting class: a pre-study


The aim of this project is to investigate the potential in decreasing the energy use of road lighting by a revision of the guidelines regarding the selection of lighting level. The starting point of this work has been the method for selection of lighting classes suggested in the recently published technical report CEN/TR 13201-1, which considers road lighting for drivers and for vulnerable road users. In order to investigate whether CEN/TR 13201-1 is applicable in Sweden, a literature review on guidelines and criteria for selection of road lighting classes was carried out, with the aim of identifying criteria that are scientifically grounded. The literature review was supplemented by a workshop where road lighting criteria were discussed by invited road lighting experts from the Nordic countries. The results from the study show that there is some support that the parameters traffic volume, traffic composition, separation of carriageways, ambient luminosity and navigational task are relevant for the selection of road lighting class, but also that there is a lack of knowledge of road users’ needs and experiences of road lighting. The report gives recommendations for further work on a revision of the guidelines for road lighting, and suggestions for further research studies.

Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.

Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...


New climate-proof solutions for hard surfaces in cities

High-density road infrastructure that emphasise maximum durability and minimum maintenance create inflexible systems, which put increased stress on urban trees and lead to increased risk for flooding. Over the past five years, the ‘Climate-proof solutions for...


VTI is preparing for automated vehicles

Automation of traffic systems will lead to major changes. The European Union’s (EU) CoEXist research project began in June 2017 with the aim of preparing cities and road operators for the introduction of self-driving vehicles. The Swedish National Road and...


Vehicle Driver Monitoring: sleepiness and cognitive load

To prevent road crashes it is important to understand driver related contributing factors, which have been suggested to be the critical reason in 94 per cent of crashes. The overall aim of the project Vehicle Driver Monitoring has been to advance the...
