This presentation describes the new features
and changes introduced in
SCATS 6.10 Commercial Release.
SMUG 2013

Corporate Delivery Plan (2012-2013)
• Improve the efficiency of the road network during peak times on
Sydney’s road corridors, including supporting road based public
transport.
 Develop an Intelligent Transport System Strategy to drive the
ongoing development of the SCATS and associated traffic
management systems.
 Develop the Smart Managed Motorways concept for the M4
Motorway to improve travel flow efficiency and road user safety.

SCATS 6.10: Objectives
• Improvement of traffic management capabilities through the addition
of new features as well as enhancements of existing SCATS
functionality.
• Provide a better interface to external ITS applications.
• Lay down the foundation for future SCATS technologies (i.e. new
TRAFF protocol support).
• Improve existing Ramp Metering management within SCATS.

SCATS 6.10: Scope
• Improve traffic management: re-engineer adaptive SCATS
• Improve intersection diagnostics: New History File & Walks
• Introduce robust repository: Site Inventory
• Improve interoperability: New ITS messages
• Enhanced monitoring: New Picture & Tablet Interface
• Continuity: New TRAFF protocol
SMUG 2013
5
Improve Adaptive SCATS
• Commence the re-engineering of some of the SCATS adaptive
operations that are handled via variation routines which limit us to
modify, enhance or add new features such as supporting more than 4
phases in ISS operations.
• Three variation routines will be enhanced in the next release:
- VR35 - Incremental Split Selection (ISS)
- VR43 - Diamond Overlap phase control
- VR59 - SD control of a diamond phase
• New operations will be optional in 6.10 – trial & feedback
SMUG 2013
6
Improve Adaptive SCATS – cont’d
• VR35 (ISS) limitations
- Intersections with 2, 3 and 4
phases
- ISS table do not contain all
possible combinations
- Maximum increment split value
is limited to +/- 4
• Introduce all possible
combinations for all
phases and configure max
split value for each phase
SMUG 2013
7
Improve Adaptive SCATS – cont’d
• VR43 - Diamond Overlap phase control
• Two modes of operation
- Introduce trailing turn
• if it’s in the selected split plan
- Introduce trailing turn
• Based on voting result
• Simple thresholds
- Cycle length
- Bay time
SMUG 2013
8
Improve Adaptive SCATS – cont’d
• Improved Strategic Approach
- VR59 - SD control of a diamond phase
- VR83 - Test an SA for congestion
- Configurable voting
SMUG 2013
9
Improve Adaptive SCATS – cont’d
• Allow SA specific options
- Instead of setting these options from
subsystem options
• Allow SA voting based on DS
or volume, and conditional
voting (VR59)
• Allow SA gating/congestion
control (VR83)

SCATS 6.10: New History File
• Combine the information already logged by HIST and IDM files as
well as log additional new information
• One daily file per Region for ALL intersections, incrementally sent to
Central Manager, similar to SM and VS
• Additional information that will be stored in the new history file
- All Walks (including Secret)
- External I/O (XSF, MSS)
- Alarms to be recorded as state changes
SMUG 2013
12
SCATS 6.10: Walk Definitions
• Provide ability to define all walks in SCATS
- Option to chose SCATS or controller managed
• Allow empty walks
- remove sequential walks definition
• Visibility of ALL walk states
- New history file to include start/termination request/ended
SMUG 2013
13
SCATS 6.10: Site Inventory
• Provide configurable data storage and report mechanism
• Import existing Site Details
- Line, Names, Camera etc
• Capture equipment details
- Log changes
• Add new information
- Power Supplier, Network Provider
- In Service/Out Service
SMUG 2013
14
SCATS 6.10: New ITS messages
• Keep existing ITS as it is
• Introduce new port/protocol that allows new paradigm – extendable
& authenticated
• Closer integration with SRMS
- Provide access to more Central Manager functionalities – special dates
• Interoperability
SMUG 2013
15
SCATS 6.10: New Picture
• Provide real-world layout for intersections
- Support new requirements
• Design and implement SCATS Spatial Data
- Easier to integrate other systems
• ITS extension to manage intersection pictures
- Import/Export spatial attributes
SMUG 2013
16
SCATS 6.10: New TRAFF Protocol
• Open paths to improve intersection efficiency, responsiveness and
provide data reporting to improve network coordination
- Plan-based operation
• Increase number of phases, approach timers etc.
• Allow phase order to be variable
- Supporting mechanism to repeat any phase in the sequence
• Send all signal group colours to SCATS
- Green, Yellow, Red, and flashing state
