Road Pricing

07.62 / 07.65 / 08.23 / 08.55
From 2007 to 2008
In 2008, TML examined for the Flemish government what the impact would be of road pricing for trucks in Flanders.

Effects on Society

In total, 9 scenarios have been analysed, ranging from a budget neutral variabilisation of the road taxes towards a fully differentiated internalisation of all external costs. The effects were compared with the trend situation in 2020 and 2030.

The following effects are expected:

- The price of one kilometre driven with an average truck will raise from 1.18 euro (in 2020) to something between 1.18 and 1.50 euro, depending on the chosen scenario.
- Less truck traffic on the road in Flanders: 0.75% up to 3.4%
- The decrease of truck km is the largest on the motorways, even in the scenarios where all ways become taxed.
- Income Flemish government has raised: decrease with 112 millions euro in 2020, by abolishing the traffic tax and the Eurovignette. Income of road pricing: 200 up to 600 million euro.
- The abolished truck km are converted into other transport alternatives (rail, inland shipping) but only for a small part (1% up to 5% of the ton km). The major part disappears in shorter routes (destinations) and changed company logistics (supplies).
- The impacts on the speed, the passenger traffic and the emissions are very small.
Price of an average truck, in €/vkm, 2020

The graph 'Million vehicle-km in 2020, per scenario, per transport mode' (see attach) gives the impact of each scenario on the vehicle-km in 2020. Note that large trucks (above 32 tonne) count for more than half of the driven kilometres. This is logic, as large trucks are used for international transport and drive more hours per day than small trucks.

Note also that the effect of a kilometre charge is fairly small on the other modes (rail and inland shipping). A small (scenario A) or large (scenario E) kilometre charge has mainly an impact on the truck transport itself.

The calculations were carried out with the TREMOVE and ISEEM models.

Technology and implementation issues

A separate report as a background document on the different technology options was produced. For this not only technologies for HGV road charging were considered, but also those for road user charging more generally.

The information presented in the final report relates to both existing systems and planned systems. The methodology relates mainly to two key activities, to carry out a literature review, and to conduct a number of expert interviews with stakeholders that are involved in implementing, operating, and maintaining a road user charging scheme.

The results and findings from these two activities were then analysed in view of their implications for the planned scheme in Flanders/ Belgium. For the literature review any recent project reports, academic papers, technical papers, working documents, etc. on road user charging schemes, which are in the public domain were reviewed. For the expert interviews a framework of main user groups that are involved in implementing, operating, and maintaining a road user charging scheme has been developed, with the aim of conducting interviews with experts that are representing all of the main user groups that have been identified.

The key issues that have been identified for the purposes of this study include the following:

- Functional Architecture
- Technology and Systems
- Operating Characteristics
- System Interoperability
- State-of-the-Art of Schemes
- On-Board Equipment
- Infrequent Users
- Additional Services
- Eurovignette Directive
- Capital and Operating Costs
- Public-Private Partnerships
- Misuse and Enforcement
