Application Areas
Application areas are deployment-oriented categories that focus on commonly deployed ITS services or systems. Application areas provide a starting point for identifying the ITS standards that may be relevant to a specific type of deployment.
The architecture flows in the ITS Architecture for Canada may be categorized based on interface classes. Each interface class is further subdivided into application areas. Interface classes are defined by the type of system at each end of the architecture flow: centre, field, vehicle, and traveller. An application area within the centre-to-field interface class would include bidirectional communication between a centre system (e.g., traffic management subsystem) and a field system (e.g., roadway subsystem).
To determine which standards may be applicable, first identify the interface class for which you are looking for a standard, then find the application area within that interface class that best describes the project component. ITS projects could include a single application area (such as a dynamic message sign deployment) or more than one application area (traveller information collection from various centres and dissemination of the information to travellers). Use the table below to learn more about application areas and associated standards.
| ITS Architecture for Canada Interface Class | Standards Application Areas |
|---|---|
| Centre to Centre - This class of application areas includes interfaces between transportation management centres. |
Data Archival Incident Management Rail Coordination Traffic Management Transit Management Traveller Information |
| Centre to Field - This class of application areas includes interfaces between a management centre and its field equipment (e.g., traffic monitoring, traffic control, environmental monitoring, driver information, security monitoring, and lighting control). |
Data Collection/Monitoring Dynamic Message Signs Environmental Monitoring Lighting Management Ramp Metering Traffic Signals Vehicle Sensors Video Surveillance |
| Centre to Vehicle/Traveller - This class of application areas includes interfaces between a centre and the devices used by drivers or travellers. It includes interfaces with motorists and travellers for exchange of traveller and emergency information as well as interfaces between management centres and fleet vehicles to support vehicle fleet management. |
Mayday Transit Vehicle Communications Traveller Information |
| Field to Field - This class of application areas includes interfaces between field equipment, such as between wayside equipment and signal equipment at a highway rail intersection. |
Highway Rail Intersection (HRI) |
| Field to Vehicle - This class of application areas includes wireless communication interfaces between field equipment and vehicles on the road. |
Probe Surveillance Signal Priority Toll/Fee Collection Vehicle Safety |
| Vehicle to Vehicle (On Board and Vehicle Coord) - This class of application areas includes communications links between devices on-board a vehicle as well as direct wireless communications links between vehicles. |
Vehicle Safety |
Note that not all possible application areas in the ITS Architecture for Canada are included in the table above.
