New volume delay functions with intersection delay (English)
Abstract [sv]

Denna rapport presenterar metod och resultat för framtagning av nya restidsfunktioner till trafikprognosverktyget Sampers. Restidsfunktioner innehåller en del som beskriver fördröjning på vägen och en del som beskriver fördröjningen i samband med korsningar. Då det är svårt och dyrt att göra samtidiga mätningar av trafikflöden och restider har en alternativ ansats använts där restidsfunktionerna kalibrerats baserat på beräkningar av korsningsfördröjning för olika korsningsutformningar med korsningsmodellen Capcal. De framtagna restidsfunktionerna har testats och validerats och är nu implementerade i Samperssystemet.

Abstract [en]

This report presents method and result for the development of new travel time functions for the Swedish national transport planning modelling system Sampers. Travel time functions include one part that describes the travel time delay on road links and one part that describes the delay at intersections. It is difficult and expensive to conduct synchronized measurements of traffic flow and travel times. An alternative approach has therefore been applied in which the travel time functions were calibrated based on calculations of intersection delay for different intersection designs using the intersection delay and capacity model Capcal. The travel time functions developed were tested and validated are now implemented in the Sampers system.
