Design for transportation vehicle detector abstraction

Conceptual Middleware Detector Device Architecture Author: Dave Verma Associate & ITS Technical Expert Beca Transportation david.verma@beca.com +64274708178 NZTA Performance Metrics Project Ethernet LAN Dynac SCATS Diagram notes: Ethernet Concept : Use abstraction layer to mitigate the LAN following issues: 1) Prevention of proprietary drivers and software interfaces to third party applications (i.e. Loops at position A could be replaced with Radar and no Ethernet WAN change is required at Dynac end. Benefit – Money Ethernet WAN and Support impacts Golden River (GR) & Third party Applications (Backup Service) 2) Removal of single points of failure and Used for maintenance and calibration of Loops and Clustered NZTA abstracted dependencies – note failure or performance issues Detectors modular connector applications with Dynac do not impact on Performance Metrics designed to fit 99% of Loop Project or vice versa. Benefit – Higher levels of Ethernet WAN detectors and process information into a simple SQL/ service and resilience are possible SNMP / NTCIP data feed for Dynac and NZTA Performance 3) Discourages anti-competitive reactions from Metrics project whilst preserving vendors and invests intellectual property ownership Ethernet Network Loop ID and State information in NZTA. NZTA own Intellectual property for Fibre/ Wireless middleware and can enforce standards with detector vendors in tenders without vendors seeing this as loss of competitive advantage – also means that competitive tension is maintained in procurement processes. Gives NZTA a big stick to hit non performing vendors with i.e. no dependency issues. (i.e. NZTA able to run any software it likes in parallel with any software it has ) SCATS QTC RMS Loops GR /Tyco Tild / Wavetronix / EIS /Trafficon 4) Allows Dynac to get information from SCATS RMS without integrating to SCATS – SCATS is seen as another detection device.
