ABSTRACT
This chapter suggests the 'theoretically acceptable' alternatives in other sets of design options. It shows that the grounded theory of acceptability of urban road pricing can be used to understand the parts of the interviews where respondents considered different design options. The design options about the charging structures are investigated; where charging structures reflect the choice between time-, distance- or cordon-based charging. One of the important sets of design options for urban road pricing involves the extent of the scheme. This includes the area that the scheme encompasses and the time during which the scheme operates. If the charged area or time is not directly the same as where or when the revenue is spent on solutions to traffic problems, the grounded theory stresses that the link between the people that pay the charge and the cost of solutions to problems they cause needs to be firmly established.
