SCATS Update SNUG, February 2017 Tauranga - 1 -
SCATS Update Feb 2017 SCATS 6.9.3 CR reported issues SCATS 6.10 CR New features VC5.1 trial results SCATS Priority Engine (SPE) trial results Planned work packages Vehicle detection technology Upstream vehicle detection External detectors - 2 -
SCATS 6.9.3 CR - Issues Pedestrian movement terminates on expiration of minimum green interval RPS before NXP Phase gap events not recorded as specified Rare incorrect VC 5.x recognition Communication stalls set to VC=4! Patch released 6.9.3 Build 21 If CL > 180 seconds, SK=AR! fails - 3 -
SCATS 6.10 CR prepared New ITS interface System status Intersection status/monitor Scheduled Dwell replacing GWR SDS support TransIS replacement SPaT map and message SSDI spatial support for measured data SPE SPE-Web interface Spatial queries instead of SCATS centric - 4 -
SCATS 6.10 CR - contd SCATS SIM Repeatability Access: support new operating systems Windows 10 Access uses true-type font Unlimited VR Increased the number of scheduler items Provide SS fallback reason Show last 4 voted SP, LP, marriage - 5 -
VC5.1 trial 4 x each controller type deployed True signal group state verified Intersection fallback - verified Issues SS fallback is not managed as specified Detector state gets stuck on actuation VC6.2 is now compiled (VC6.1 + VC5.1) - 6 -
SPE trial: PTIPS PTIPS replacement - 7 -
SPE trial: TPE extension - 8 -
SBC 1: vehicle detection Re-wiring of existing induction loops Provide information on travel speeds and vehicle lengths New detection technology: Count on half loop Calculate DS with full loop Optimise the offset time between intersections - 9 -
SBC 2: upstream detection Measure all arriving vehicles, including queued vehicles, using mid-link upstream detectors Improve SCATS real-time optimisation at the downstream traffic signals Combine with SBC1 (detection technology + associated SCATS algorithm changes) Improve congestion measurement slow short vehicle from an efficient, fast long truck - 10 -
SBC 3: external detectors Enable use of IP base detectors Provide drivers for converting continuous detection to SCATS input (Vo, NonOcc) Provide interface delivering speed and length of each vehicle/pedestrians Ability to define SI in a region from external sources - 11 -
