Dynamiska farthinder: en litteraturstudie

Omar Bagdadi

To mitigate the negative consequences from rigid speed humps, several alternative solutions have emerged on the market, so called dynamic speed humps. The dynamic speed humps can be classified into passive or active humps, respectively. This means that a speed hump could be either actively dynamic or passively dynamic. A passive dynamic speed hump is designed to let heavy vehicle pass almost unnoticed while light vehicles are subjected to a hump similar to a rigid speed hump and should thereby reduce their speed accordingly. An active dynamic speed hump is designed to only be active when a speeding vehicle is approaching. The intrusion on traffic flow is thereby smaller and the traffic may maintain a more even speed according to the speed limit since the hump does not affect the traffic at all as long as the speed limit is respected. The conclusions are that both passive and active dynamic speed humps are of interest and could be used as an alternative or complement to rigid speed humps. However, it is important that the purpose of the installation of the hump is clear in order to obtain the desired effect.

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...
