Study of the accessibility inequalities of cordon-based pricing strategies using a multimodal Theil index

• The implementation of an appropriate pricing policy in an urbanarea could alleviate both environmental and congestion problemsby encouraging a shift towards more sustainable modes oftransportation. However, any positive net social welfare balancedelivered by the policy can hide unacceptable regressive effects.Therefore, it is crucial to investigate any change in relative levelsof accessibility among different categories of transport networkusers.This study focuses on the application of a cordon-basedcongestion pricing scheme on a multimodal network, whereprivate cars and public transportation coexist, and includes asensitivity analysis by varying the size of the charging area andthe amount of the toll, for a monocentric urban reality. Takinginto account an elastic demand associated with each proposedcharging scenario, the related distributional effects are exploredusing the Theil index, with a quantitative assessment of theinequalities in the accessibility variations across the users of thenetwork.
