SCATS, SPLITS AND OFFSETS SIMPLIFIED (SOS)
SCATS is an adaptive coordinated traffic signal system. Its adaptive method requires a predetermined data base inclusive of a library of phase split plans and offset plans for each intersection, and offset plans and control parameters for each sub-system. The ultimate performance of SCATS depends on the accuracy of this data base in terms of catering for the expected range of traffic conditions and in conforming to the requirements of the SCATS software. The australasian wide use of the system as planned will result in 49 SCAT systems controlling 4400 sets of traffic signals. Experience to date has shown that New South Wales Department of Main Roads conducted training programs can transfer the necessary skills to generate these data bases but the activity within each user authority remains a specialised function. To ensure that the system can be operated in the future with less specialised training and skills the authors have written two off line computer programs. These allow non-specialist practitioners to generate interactively from basic information a data base which will ensure reliable and effective operation. The programs provide an output in exact scats format which specifies the phase split plans, the offset plans, associated control parameters and the detector specification required. The paper describes the application of the programs. The number of the covering abstract for the conference is TRIS No. 393385. (Author/TRRL)
