Abstract [sv]

På uppdrag av Vägverket Region Mälardalen har Statens väg- och transportforskningsinstitut (VTI) studerat effekten av vidtagna åtgärder på gatunätet i fem tätorter. De effekter som studerats har gällt säkerheten, framkomligheten, gas-, partikel- och bulleremissioner från biltrafiken, Vidare har trafikanternas uppfattning om vidtagna åtgärder och deras effekter följts upp. Detta har gjorts via enkäter. De åtgärder som vidtogs var sådana som reducerade bilarnas hastigheter och minskade de oskyddade trafikanternas exponeringssträcka. Cirkulationsplatser, cykelbanor och refuger anlades. På en plats testades en cirkulationsplats med tredimensionellt målad rondell. Andra åtgärder som vidtogs var att upphöja gång-/cykelöverfarter, förbättra belysningen vid gång- och cykelpassager. Platserna videofilmades. Detta material låg till grund för bedömning av trafiksäkerhetseffekten, trafikanträkningar och bestämning av bilarnas hastigheter i punkter där oskyddade trafikanter korsade gatan. Slangmätningar utfördes för att komma åt vägval och restider. Bilarnas körförlopp kartlades på en plats via ”förföljelsebil”. Bilarnas gas- och partikelemissioner beräknades med den s.k. VETOmodellen. Modell användes också för att beräkna åtgärdernas effekt på trafikbullret.

Abstract [en]

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.
