This guideline specifically covers AMS balise placement when Target Speed Monitoring is needed, which includes: - High risk turnout only - High risk overlap deficiency - High risk end of lines / buffer stops - High risk speed sign consideration - Calibration BG consideration To gain a complete overview of ATP / AMS signalling design requirements, this document should be read in conjunction with the AMS suite of signalling design principle modules. material Reference 4912713_38 QUALITY MANAGEMENT SYSTEM DeskSite Reference: 4912713 © TfNSW 2017 UNCONTROLLED WHEN PRINTED Page 4 of 36 BALISE ARRANGEMENT FOR HIGH RISK LOCATION DESIGN GUIDELINE Infrastructure and Services : ATP / AMS Program Project type: Major Table of contents 1.
