Adaptation patterns in trip chaining and trip tour behavior with congestion charges in Gothenburg.

University essay from KTH/Transportvetenskap


Gothenburg introduced a time-of-day dependent cordon-based congestion

charging scheme in January 2013. This paper explores how the introduction

of the Gothenburg congestion charging scheme has affected trip tour and

trip chaining behavior, using panel surveys conducted in 2012 and 2013,

before and after the Gothenburg congestion charging began. This study

proposes a typology of trip tour and trip chaining behavior based on

organization of trips. Further, the study develops a series of indicators to

characterize trip chains and trip tours patterns. Descriptive analysis is used

to compare travel patterns before and after congestion pricing at the daylevel,

tour-level and stage-level. The analysis results show that car travelers

not only suppress activities to a small extent but also tend to have simpler

tour patterns after the congestion charges implementation. The adaptation

patterns reduce charges paid to some extent. In general, the reorganization

of activities taken from on the way from work/school to home contributes

greatly to reducing the congestion charges paid. A linear model is also

developed to identify the effects of socio-demographic factors and

contextual factors on the amount of charges paid based on panel data.
