The Swedish Road and Transport Research Institute (VTI) has studied the effects of measures taken on the street network in five towns. The effects studied were safety, trafficability and environmental impact (as the effect of gas, particle and noise emissions). The measures taken were physical measures with the principal purpose of reducing vehicle speeds and reducing the distance over which pedestrians and cyclists were exposed. The levels of intersections were raised, pinch points or chicanes were constructed along streets, different types of surfacings were laid in order to reinforce the perception of a reduced street space. Before and after studies were performed. The sites were videoed. The results of this formed the basis for assessing the safety effect and determining trafficability and vehicle flows. The video footage was also used to determine the speed distribution of vehicles on pedestrian and cycle crossings. The driving pattern of vehicles was studied with the help of the pursuit vehicle at some of the sites in order to determine the speed reducing effect of the measures along the street. The gas and particle emissions of vehicles were estimated using the VETO model. This model was also used to make an advance estimate of the effect of the measures on traffic noise. Attitude surveys were conducted at the sites to determine the opinions of road users concerning the measures.

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...
