Functional Objects

Functional ObjectDescriptionUser Defined
ITS Communications Support'ITS Communications Support' provides means to send and receive messages to and from other ITS Objects. It provides mechanisms for scheduling and prioritizing communications traffic. It may also provide relay functions.False
Transit Vehicle On–Board Connection Protection'Transit Vehicle On–Board Connection Protection' monitors vehicle schedule performance and provides it to the transit center for connection protection processing. It receives operator instructions relating to managing connection protection and recognizes individual travelers who have arranged for connection protection and provides connection protection information to the transit center.False
Transit Vehicle On–Board Fare Management'Transit Vehicle On–board Fare Management' supports fare collection using a standard fare card or other non–monetary fare medium and detects payment violations. Collected fare data are made available to the center.False
Transit Vehicle On–Board Paratransit Operations'Transit Vehicle On–board Paratransit Operations' forwards paratransit and flexible–route dispatch requests to the operator and forwards acknowledgements to the center. It coordinates with, and assists the operator in managing multi–stop runs associated with demand responsive transit services including paratransit. It collects transit vehicle passenger data and makes it available to the center.False
Transit Vehicle On–Board Trip Monitoring'Transit Vehicle On–Board Trip Monitoring' tracks vehicle location, monitors fuel usage, collects operational status (doors opened/closed, running times, etc.) and sends the collected, time stamped data to the Transit Management Center.False
Transit Vehicle Pedestrian Safety'Transit Vehicle Pedestrian Safety' exchanges current location and motion information with pedestrian–carried devices in the vicinity and uses that information to warn the driver of pedestrians in the vehicle's path. Information from on–board sensors (e.g., radars and image processing) are used to augment the short range communications, if available. In addition to notifying the driver, control information can also be provided to support automated control functions that can avoid the collision.False
Transit Vehicle V2V Safety'Transit Vehicle V2V Safety' exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to predict vehicle paths, and notifies the driver when the potential for an impending collision is detected. Information from on–board sensors (e.g., radars and image processing) are used to augment the V2V communications, if available. In addition to notifying the driver, control information can also be provided to support automated control functions that can avoid the collision. This object is similar to the 'Vehicle Basic V2V Safety', but it accounts for crash scenarios that are unique to transit vehicles (e.g., Vehicle Turning Right in Front of Bus). It is also stop–aware since stop locations pose specific crash threats for transit vehicles. Finally, the detection and control algorithms, filters, and timing account for bus performance and risk profiles associated with remote vehicles that are unique to transit.False
Vehicle Map Management'Vehicle Map Management' supports map updates and makes current map and geometry data available to other applications. It manages map data on–board and provides map data to end–user applications that provide location–based services.False
Vehicle System Executive'Vehicle System Executive' provides the operating system kernel and executive functions that manage the software configuration and operation and support computer resource management, security, and software installation and upgrade.False
Vehicle System Monitoring and Diagnostics'Vehicle System Monitoring and Diagnostics' includes on–board sensors and integrated self test software that monitors the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance. The status of the vehicle and ancillary equipment and diagnostic information is provided to the driver and service center.False
