A technological and innovative solution for road charging,
eCall, and other services

In view of road charging for passenger cars, several companies grouped
themselves into a consortium that devised a technological solution. The idea is
for each vehicle to be equipped with a device (the on-board unit, OBU). Thanks
to an innovative solution, the (removable) OBU is uniquely identifiable with the
vehicle, which makes the technology fraud-proof. The OBU has a GPS, making its
location always known. Besides this, the OBU can also communicate over the GSM
network via GPRS. The location of the vehicle is transmitted in real-time to a
computer (the back-end server), which on the one hand determines the exact
position of the vehicle (the map-matching), and on the other hand calculates the
cost per kilometre. This information is sent back to the OBU, allowing the
driver to know what the cost of the trip was. At the end of the journey, an
invoice can be made. The system is quite flexible:

  • It can be used for both passenger cars and trucks.
  • The tariffs hold for individual roads, or for entire areas (eg. a city).
    They can therefore be different for motorways and local roads.
  • Besides this, the tariffs are different with respect to the time of day (eg.
    morning- and evening rush hours, off-peak periods).
  • There is also a distinction between the different types of vehicles (engine
    capability, emissions, …).
  • It is a technological versatile solution, in which different services can be
    offered: road charging is one example, eCall another. In this way, other
    companies on the market can offer their information in an integrated way.

We expect that from the beginning of September on, 15 drivers from Leuven
will perform tests with a car and on-board unit, simulating road charging
amongst other things. TML's contribution to the consortium is mainly the
construction of a solid support on which the tariffs for road charging can be
based. At a later stage, more test drivers will be available. Based on this, we
check together with the City of Leuven as to which end road charging can offer a
solution for the city's mobility problems.
