SCOOT Version 3.1

SCOOT Version 3.1 was introduced in 1995. The main new facilities provided were:

Bus Priority. A facility has been introduced to integrate active priority to buses or other public transport vehicles. The system is designed to allow buses to be detected either by selective vehicle detectors or by an automatic vehicle location (AVL) system.
ASTRID (Automatic SCOOT Traffic Information Database). ASTRID is a database designed to take information from SCOOT and to process and store it for later retrieval and analysis.
INGRID (Integrated Incident Detection). INGRID is a system operating in real time which uses information from the SCOOT detectors together with historic data from ASTRID to automatically detect incidents. Improved faulty detector logic. SCOOT 3.1 can use the historic data from ASTRID to replace data from faulty detectors. Flexible Optimiser Authorities. The amount by which the optimisers can change the signal timings has been made more flexible and can be increased at higher cycle times and under incident conditions.
