Abstract [sv]

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

improvement measures

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.
