Traffic Management Centres (TMCs) have evolved extensively over the last several years. Monitoring road conditions through loops and CCTV and responding to events by changing variable speed and message signs have become just a subset of management functions undertaken in today's TMCs. Advances in technology offers more, the public expects more, and policy changes mandates more from a TMC. The National Network Control Centre (NNCC), which operates Scotland's National Driver Information and Control System (NADICS) on behalf of the Scottish Executive, has been surrounded by constant change in every aspect of their business for some years now. As one of the more established national control centres in Europe, it has managed to deliver services effectively while embracing this constant change. This paper reports on the experiences the NNCC has had in managing change. After briefly describing the NADICS system and its operations, the paper looks at the types of change occurring, the contributors to success in handling change, the challenges, and the methods by which change management can be employed.
