The fare structure can be used as a way to control the mix of vehicles and walk-on passengers. For all three categories of oversized vehicles included in this study, ridership was elastic with respect to fares. Increasing those fares apparently causes people not to make those trips or to divert them around the Sound. This finding lends support to the idea of providing an off-peak discount for those vehicles. To achieve a higher degree of certainty in these findings and to make quantitative estimates of revenue impacts of fare changes, a different approach is required than the one used in this study.
Data needs to be collected on a disaggregate basis.
