Speed-flow relationships for Swedish rural roads : Suggestions for revised relationships based on traffic measurements from 2012–2015 (English)
Abstract [sv]

Hastighetsflödessamband är en viktig del i Trafikverkets modell för bedömning av Effekter vid väganalyser (EVA). I denna rapport presenteras förslag till nya hastighetsflödessamband för motorvägar, fyrfältsvägar, mötesfria motortrafikleder, mötesfria landsvägar samt tvåfältiga landsvägar. Förslagen baseras på data från mätningar med Trafikverkets trafikmätningssystem (TMS) samt kompletterande modellberäkningar. För varje vägkategori har TMS-datamaterialet kvalitetssäkrats, bearbetats och analyserats. Datamaterialet presenteras i form av hastighetsflödesdiagram för personbilar, bussar och lastbilar utan släp samt lastbilar med släp. För varje typsektion har sedan en jämförelse av nuvarande samband och mätdata genomförts. Vid behov har förslag till revidering av nuvarande samband tagits fram. De mest signifikanta förändringarna jämfört med föregående revidering från 2013 är: medelfrihastigheten för lastbilar utan släp har generellt sett ökat på samtliga vägtyper utom tvåfältsvägar där hastigheten minskat; medelfrihastigheten för lastbilar med släp har generellt sett minskat; hastigheten på tvåfältsvägar har generellt sett minskat.

Abstract [en]

Speed-flow relationships are an important part of the Swedish Transport Administration (Trafikverket) model for evaluation of effects of road facilities (the EVA model). This report present suggestions for new speed-flow relationships for motorways (MV), low standard motorways (4F), oncoming lane separated highways with grade separated intersections (MML), oncoming separated highways with at grade intersections (MLV), and two-lane highways. The suggestions are based on data from measurements using the Swedish Transport Administration’s traffic measurement system TMS in combination with model calculations. The TMS data have, for each road category, been quality checked, processed and analysed. The data material is presented as speed-flow diagrams for passenger cars, buses and trucks without trailer, and trucks with trailers. A comparison of the current speed-flow relationships and the TMS-measurements was then conducted for each road category, and if needed a suggestion for a revision was presented. The most significant changes from last revision from 2013 are: average free flow speed for trucks without trailer have in general increased for all road types except two lane highways for which the speed has decreased; average free flow speed for trucks with trailers have in general decreased; and the average speed on two lane highways have in general decreased
