The SCOOT (split, cycle and offset optimisation technique) method of traffic-responsive urban traffic control is now operating in more than 130 towns and cities worldwide. This paper describes the latest version of SCOOT and how it is integrated with the ASTRID database and the INGRID incident detection system. SCOOT version 3.0 was issued in June 1995. This version incorporated bus priority as developed within the European Union DRIVE project PROMPT with supporting funding by the UK Department of Transport. SCOOT version 3.1, the latest version, was issued in September 1995 and further included modifications to SCOOT to allow the integration of SCOOT with ASTRID and INGRID. The ASTRID and INGRID programs, developed within the DRIVE projects ROMANSE and HERMES with funding from the Department of Transport, were issued by TRL at the same time. Other enhancements in version 3.1 include the use of historic data from ASTRID when detectors are faulty and greater flexibility in the split and offset optimisers when operating at higher cycle times and under incident conditions. These enhancements were developed as part of a contract with Siemens Traffic Controls Ltd and Peek Traffic Ltd. ASTRID and INGRID are not essential to the operation of SCOOT but provide optional extra facilities.
