Traffic congestion in Dublin has reached relatively high levels despite the existence of a concentrated plan to improve public transport and offer reliable and feasible alternatives to motorists. The difficulty is primarily due to the slow and piecemeal introduction of the public transport alternatives proposed by the Dublin Transportation Initiative (DTI, 1994) teamed with an unprecedented rise in car ownership and usage levels related to increased economic activity in Ireland in recent years.
It is against this background that road use pricing has recently been the subject of a scoping study commissioned by one of the Irish government departments, the aim of which is to examine the potential for road use pricing in controlling traffic congestion in the city. Needless to say the integration of such ameasure with the integrated package of measures already recommended for Dublin would be a fimdamental issue to be examined by such a study.
Other Dublin based research on road use pricing has been the subject of a two-year EU funded project entitled EUROPRICE (O'Mahony et al, 1999), funded under the DGXVII SAVE II Programme. It aimed to evaluate the potential user response through a small pilot-action, to estimate the impact on the use of energy and the impact on traffic congestion.
The means by which user response was measured in Dublin was through participation of a sample of individuals in a road use pricing field trial. In addition to the field trial, modelling runs using the DTO transportation network model were conducted to estimate the potential energy savings likely to accrue. Below is a description of the work conducted in Dublin for the EUROPRICE project. Firstly, the specific objectives of the work are outlined followed by descriptions of the pricing regime and the participants involved in the pilot-action. A smnmary of the results of the field trial and the modelling runs to estimate energy savings are then presented.
