The Dutch Ministry of Transport is upgrading its Motorway Traffic Management system that it has operated since 1981. The system is subject to major functional and technical extensions and while the installed base of road-side equipment is either being preserved or adapted for continued use, at the same time an "open", competitive market is being created for new outstations to be purchased as commodity items for current and future orders. The paper discusses specification, development, certification and purchasing phases. From the government point of view, the approach described promotes lasting supplier competition, maximum security and - in the long run - little hassle. On the down side, initially the process is time-consuming and not very cost-effective.
