The role of public transport for feasibility and acceptability of congestion charging - The case of Stockholm

In the Stockholm Trial, congestion charges and the expansion of public transport services were closely linked together in marketing efforts, as well as in political decisions. In this paper, the authors analyse the role that public transport may have played in increasing acceptability and feasibility of the scheme. The authors study four aspects of the relationship between charging and public transport provision: (i) the initial modal share, (ii) contribution to modal shift (iii) compensation to losers (iv) revenue hypothecation. Their analyses, based on a combination of primary and secondary data, support the hypothesis that public transport contributed to the successful implementation of congestion charging in Stockholm through all those four mechanisms
