SNUG, February 2017 Tauranga SCATS Update SNUG, February 2017 Tauranga

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

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

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

SCATS 6.10 CR - cont’d 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

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)

SPE trial: PTIPS PTIPS replacement

SPE trial: TPE extension

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

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

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
