Åtgärder på det kommunala vägnätet i fem tätorter: demonstrationsprojekt i Vägverket Region Mälardalen år 2001/2002
2003 (Swedish)Report (Other academic)
By commission of the Mälardalen Region of the Swedish National Road
Administration, the Swedish
Road and Transport Research Institute (VTI) studied the effect of
improvements to streets in five
towns. The effects studied related to safety, accessibility, emissions of
gases, particulates and noise
by vehicles. The views of road users regarding the improvements and their
effects were also
examined. This was done via questionnaire surveys. The improvements were
intended to reduce
vehicle speeds and the distance over which vulnerable road users were exposed
to vehicular traffic.
Roundabouts, cycle tracks and refuges were constructed. At one site a
roundabout with a traffic
island painted so as to give a three dimensional impression was tested. Other
were raising of pedestrian/cycle crossings, improvement of lighting at
pedestrian and cycle crossings.
The sites were videoed. This material was used as the basis in assessing the
traffic safety effect,
counting road users and determining vehicle speeds at points where vulnerable
road users crossed the
street. Pneumatic tube measurements were made to determine route choice and
journey times. At one
site, the driving patterns of vehicles were surveyed via a pursuit vehicle.
The gas and particulate
emissions of vehicles were calculated with the VETO model. This model was
also used to calculate
the effect of the improvements on traffic noise.
