IMPLEMENTING ROAD USER CHARGING IN SATURN

This working paper details modifications carried out to the congested assignment traffic network model SATURN in order to represent mad user charging. The work was undertaken as part of an SERC funded study to investigate the network effects of a series of alternative road user charging systems upon an existing road network. Four road user charging systems which were tested during the study have been represented in SATURN. These are toll cordons, time-based charging, congestion charging and distance-based charging.
