Renewal of street and road lighting in Swedish municipalities

We studied planning, responsibilities, and stakeholder’s involvement in 12 Swedish municipalities of different size to identify factors that could constitute barriers for developing more energy efficient street and road lighting (SRL). In this study, small municipalities had the most energy efficient lighting and all stated that energy savings were the main reason for their substitution of mercury lamps. In medium-sized and large municipalities the ecodesign directive was given as the main motive for renewal of the SRL by four municipalities, and the remaining four municipalities stated that their main motive was the need to replace old SRL. Outsourcing of management, operation and maintenance may constitute a barrier for renewal whereas lack of knowledge and costs for renewal does not seem to be any significant barriers. Integration of SRL planning with other strategies, such as energy and economy strategies, seems to be an important factor for a proactive SRL development.

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...
