Abstract [sv]

Statens väg- och transportforskningsinstitut (VTI) har studerat effekten av vidtagna åtgärder på gatunätet i fem stycken tätorter. De effekter som studerats har varit säkerheten, framkomligheten och miljöpåverkan (som effekt av gas-, partikel- och bulleremissioner). De åtgärder som vidtogs var fysiska åtgärder med huvudsakligt syfte att reducera fordonens hastigheter och att minska de oskyddade trafikanternas exponeringssträcka. Korsningar höjdes upp, gator smalnades av eller sidoförsköts, olika typer av beläggningar anlades i syfte att förstärka upplevelsen av ett mindre gatuutrymme. Före- och efterstudier genomfördes. Platserna videofilmades. Resultatet av detta låg till grund för bedömningen av säkerhetseffekten och för framkomlighets- och flödesbestämning. Det filmade materialet användes också för att bestämma fordonens hastighetsfördelning på gång- och cykelöverfarter. Bilarnas körförlopp studerades med hjälp av förföljelsebil i några av platserna för att bland annat bestämma åtgärdens hastighetseffekt längs gatan. Bilarnas gas- och partikelemissioner beräknades med den s.k. VETO-modellen. Modell användes också för att förbestämma åtgärdens effekt på trafikbullret. Attitydundersökning genomfördes i platserna för att komma åt trafikanternas uppfattning om åtgärderna.

Abstract [en]

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.
