How SCOOT works SCOOT was originally designed to control dense urban networks, such as large towns and cities. It is also successful in small networks, especially for areas where traffic patterns are unpredictable. With over 200 systems worldwide SCOOT is working effectively in a wide range of conditions in places as diverse as big congested cities: Beijing, Bangkok and London, to small towns or networks such as: Heathrow airport and systems localised round individual junctions of the M25.

When junctions are some distance apart (more than about 1km) isolated junction control using a system such as MOVA may be more appropriate. Other site-specific factors may influence the decision on method of control.

Many cities have well defined main radial routes with many signalised junctions and few, if any, traffic signals between the outer areas of the radials. SCOOT has been successfully used in such cities. The areas of Birmingham and Leicester used in the emissions trials are examples of radials controlled by SCOOT.
