2.  PART B: APPLICATION & APPROVAL GUIDELINES

2.1  GENERAL

These Application & Approval Guidelines generally cover the types of fixed Intelligent Transport Systems (ITS) that are currently being utilised by Main Roads Western Australia.  It is understood that this document does not cover emerging or mobile ITS initiatives, and will therefore have to be reviewed when these new initiatives are ready for general implementation.

For application and approval guidelines for ITS refer to the Managed Freeway Provision Guidelines which have been developed as a part of ITS and Managed Freeway developments in Main Roads WA.

 

2.2  SYDNEY COORDINATED ADAPTIVE TRAFFIC SYSTEM (SCATS)

All traffic signal installations in the State shall be connected to SCATS using the form of connection approved by the Traffic Systems Operations Coordinator. In general terms this connection shall be by ADSL where optic fibre is not available.

ITS communications cabins and communications nodes are located at selected locations around the metropolitan area to ensure that the operations and ongoing costs of the system are optimised.

The Traffic Systems Operations Coordinator shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if ITS communications cabins and /or communications nodes are to be installed as part of the project, their location and functional requirements / specifications. 

All mid-block signalised pedestrian crossings shall utilise "on-crossing" pedestrian detection and a flashing yellow "give-way" signal period (Pelican) for drivers, unless special circumstances at the site make this undesirable. As this forms part of the operations of such traffic signals, the application & approval requirements are as per those for traffic signals

 

2.3  TRAFFIC MONITORING CAMERA SYSTEM

Traffic monitoring cameras assist the Traffic Operations Centre staff to manage traffic flow by allowing them to view the actual traffic conditions and activities being undertaken on the road in real-time. This assists with managing normal traffic congestion, incidents affecting the road network, road works and special events.

The Traffic Systems Operations Coordinator shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if traffic monitoring cameras are to be installed as part of the project, their location and functional requirements / specifications.

Additional details and warrants can be found in section 7.2 of the Managed Freeways Provision Guidelines.

 

2.4  VARIABLE MESSAGE SIGNS (FIXED)

Variable Message Signs (VMS) are utilised to provide information to drivers relating to the following activities: -

    • Management of real-time traffic flow and incidents affecting the road network
    • Road works / traffic management and planned events
    • General road safety
    • The promotion of alternative transport modes
    •  

The Road Network Operations Manager shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if VMS's are to be installed as part of the project, their location and functional requirements / specifications.

Additional details and warrants can be found in section 6 of the Managed Freeways Provision Guidelines.

 

2.5  ITS DUCTS & COMMUNICATIONS CABLING SYSTEMS

 In general, ITS ducts & communications cabling systems shall be provided on freeways and Control of Access Highways in the Perth Metropolitan Area.

The Asset Manager Traffic Systems shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if ITS ducts & communications cabling systems are to be installed as part of the project, their location and functional requirements / specifications.

Additional details and warrants can be found in section 8.1 of the Managed Freeways Provision Guidelines.

 

2.6  TRAFFIC COUNTING STATIONS

Traffic counting stations collect traffic data, such as traffic volumes, traffic classification and vehicle mass information. This is undertaken through a combination of temporary and permanent counting stations, which includes "Culway" weigh-in-motion sites and data collected by the SCATS traffic signal control system.

Wherever practical data from SCATS shall be utilised for traffic reporting purposes. The Manager Asset & Network Information and the Traffic Systems Operations Coordinator shall further develop these systems so that ultimately all traffic signals shall be able to be utilised as permanent counting stations, including the counting of unsignalised movements at these intersections.

The Manager Asset & Network Information shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if traffic counting stations are to be installed as part of the project, their location and functional requirements / specifications.

Additional details and warrants can be found in sections 7.1 and 7.3 of the Managed Freeways Provision Guidelines.

 

2.7  REAL-TIME TRAFFIC MONITORING STATIONS

Real-time vehicle detection stations (VDS) collect traffic volume, speed and headway information on sections of freeway as inputs for such systems as driver information systems, incident detection or freeway management systems.

The Road Network Operations Manager shall be consulted during the Project Planning phase of all major projects (i.e. when determining the project scope of works), and he/she shall determine if real-time traffic monitoring stations are to be installed as part of the project, their location and functional requirements / specifications.

Additional details and warrants can be found in section 7.1 of the Managed Freeways Provision Guidelines.
