In 1989 ASFA (the association of French toll motorway companies) launched the "Traffic" programme to follow-up traffic matters. In 1993 this group was enlarged and a "Groupe de travail économie" was created. It focused not only on traffic but also on all fields of transport economics: cost-benefit analysis, evaluation of externalities, toll management, etc
Since 1993, programmes are set up once a year made up of about 10 'actions' gathered in four main research themes:
- Analysis of current and future customers
- Motorway pricing
- Socio-economic effects of transport infrastructure
- Competition and complementarity between modes.
About EUR 300 000 in 1994, EUR 150.000 in 2001.
