Modelling Transport in an Interregional General Equilibrium Model with Externalities

Table 1

Maximum speeds, distance and time costs, road pricing tariffs (DKK) (DKK 7.50=ca 1

Euro=ca 1$US)

The estimation of level of transport activity by region, mode, purpose and by type of
consumption described above reflects a basic assumption that data on transport activity obtained
from National (transport satellite) Accounts used in a top down procedure, are superior to data
on transport activity obtained from different statistical sources, used in a bottom-up approach.

In this paper, only results based upon road pricing for private cars is presented.

Table 2 shows the consequences of introducing road pricing. It is assumed that all ferry
routes and fixed links will continue with unchanged ticket prices. The table shows that
transport costs in general increase from 2% to 13%, outside the main cities of Copenhagen
and Arhus least in the interregional links where use of rural roads is important and/or where a
significant part of the journey uses ferries. In Copenhagen and Aarhus transport costs decline
as road pricing results in a reduction of congestion, and thus, transport costs.
