The OECD Group "International Corridor Experiment" (ICE-Project) was created to examine the strategies available for traffic corridor control and to outline potential international co-orindated research that could be performed on a corridor facility of a member country on the basis of the needs of another member country. The Group's objective was to bring together and exploit the expertise on traffic control available in participating OECD countries in order to make the most rapid and efficient impact on the very complex subject of traffic corridor control. The experience of developments such as ramp control systems in the United States, co-ordinated signal control in Europe, and motorist warning systems in Japan provided the basis for the Group's work. The following five types of corridors, both in urban and in rural areas (intra-city and inter-city), were considered within the framework of the programme: 1. Motorway and motorway; 2. Motorway and co-ordinated area traffic control system; 3. Motorway and street network (unco-ordinated control); 4. Motorway and suburban road network (including controlled arterials); 5. Motorway and rural roads. The report contains six chapters, a list of key references and eight annexes.
