Includes Physical Objects:

Physical Object	Class	Description
Basic Transit Vehicle	Vehicle	The 'Basic Transit Vehicle' represents the transit vehicle that hosts the on-board equipment that provides ITS functions. It includes a specialized and extended databus that is subject to different vehicle databus standards and hosts a broad range of components that are unique to a transit vehicle including the farebox and associated electronics, passenger counters, and transit security systems. The Transit Vehicle may represent a bus, paratransit vehicle, light rail vehicle, or other vehicle designed to carry passengers.
Basic Vehicle	Vehicle	'Basic Vehicle' represents a complete operating vehicle. It includes the vehicle platform that interfaces with and hosts ITS electronics and all of the driver convenience and entertainment systems, and other non-ITS electronics on-board the vehicle. Interfaces represent both internal on-board interfaces between ITS equipment and other vehicle systems and other passive and active external interfaces or views of the vehicle that support vehicle/traffic monitoring and management. External interfaces may also represent equipment that is carried into the vehicle (e.g., a smartphone that is brought into the vehicle). Internal interfaces are often implemented through a vehicle databus, which is also included in this object. Note that 'Vehicle' represents the general functions and interfaces that are associated with personal automobiles as well as commercial vehicles, emergency vehicles, transit vehicles, and other specialized vehicles.
Driver	Vehicle	The 'Driver' represents the person that operates a vehicle on the roadway. Included are operators of private, transit, commercial, and emergency vehicles where the interactions are not particular to the type of vehicle (e.g., interactions supporting vehicle safety applications). The Driver originates driver requests and receives driver information that reflects the interactions which might be useful to all drivers, regardless of vehicle classification. Information and interactions which are unique to drivers of a specific vehicle type (e.g., fleet interactions with transit, commercial, or emergency vehicle drivers) are covered by separate objects.
Transit Management Center	Center	The 'Transit Management Center' manages transit vehicle fleets and coordinates with other modes and transportation services. It provides operations, maintenance, customer information, planning and management functions for the transit property. It spans distinct central dispatch and garage management systems and supports the spectrum of fixed route, flexible route, paratransit services, transit rail, and bus rapid transit (BRT) service. The physical object's interfaces support communication between transit departments and with other operating entities such as emergency response services and traffic management systems.
Transit Vehicle OBE	Vehicle	The 'Transit Vehicle On-Board Equipment' (OBE) resides in a transit vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient movement of passengers. The types of transit vehicles containing this physical object include buses, paratransit vehicles, light rail vehicles, other vehicles designed to carry passengers, and supervisory vehicles. It collects ridership levels and supports electronic fare collection. It supports a traffic signal prioritization function that communicates with the roadside physical object to improve on-schedule performance. Automated vehicle location enhances the information available to the transit operator enabling more efficient operations. On-board sensors support transit vehicle maintenance. The physical object supports on-board security and safety monitoring. This monitoring includes transit user or vehicle operator activated alarms (silent or audible), as well as surveillance and sensor equipment. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. It also furnishes travelers with real-time travel information, continuously updated schedules, transfer options, routes, and fares. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including transit vehicles. The Transit Vehicle OBE supplements these general capabilities with capabilities that are specific to transit vehicles.
Transit Vehicle Operator	Vehicle	The 'Transit Vehicle Operator' represents the person that receives and provides additional information that is specific to operating the ITS functions in all types of transit vehicles. The information received by the operator would include status of on-board systems. Additional information received depends upon the type of transit vehicle. In the case of fixed route transit vehicles, the Transit Vehicle Operator would receive operator instructions that might include actions to take to correct schedule deviations. In the case of flexible fixed routes and demand response routes the information would also include dynamic routing or passenger pickup information.
Transportation Information Center	Center	The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.
Vehicle	Vehicle	This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. Many of these capabilities (e.g., see the Vehicle Safety service packages) apply to all vehicle types including personal vehicles (including motorcycles), commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle includes the common interfaces and functions that apply to all motorized vehicles. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co-pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.

Includes Functional Objects:

Functional Object	Description	Physical Object
TIC Traffic Control Dissemination	'TIC Traffic Control Dissemination' serves as intermediary between transportation operations centers (e.g., TMC, Transit MC) and transportation users (e.g., vehicles, personal devices). It collects and disseminates intersection status, lane control information, special vehicle alerts, and other traffic control related information that is real-time or near real-time in nature and relevant to vehicles in a relatively local area on the road network. It collects traffic control information from Traffic Management and other Center(s) and disseminates the relevant information to vehicles and other mobile devices.	Transportation Information Center
Transit Center Fixed-Route Operations	'Transit Center Fixed-Route Operations' manages fixed route transit operations. It supports creation of schedules, blocks and runs for fixed and flexible route transit services. It allows fixed-route and flexible-route transit services to disseminate schedules and automatically updates customer service operator systems with the most current schedule information. It also supports automated dispatch of transit vehicles. Current vehicle schedule adherence and optimum scenarios for schedule adjustment are also provided. It also receives and processes transit vehicle loading data.	Transit Management Center
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.	Transit Vehicle OBE
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.	Transit Vehicle OBE
Vehicle Traveler Information Reception	'Vehicle Traveler Information Reception' receives advisories, vehicle signage data, and other driver information of use to all types of vehicles and drivers and presents this information to the driver using in-vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information.	Vehicle

Includes Information Flows:

Information Flow	Description
driver input	Driver input to the vehicle on-board equipment including configuration data, settings and preferences, interactive requests, and control commands.
driver update information	Information provided to the driver-vehicle interface to inform the driver about current conditions, potential hazards, and the current status of vehicle on-board equipment. The flow includes the information to be presented to the driver and associated metadata that supports processing, prioritization, and presentation by the DVI as visual displays, audible information and warnings, and/or haptic feedback.
driver updates	Information provided to the driver including visual displays, audible information and warnings, and haptic feedback. The updates inform the driver about current conditions, potential hazards, and the current status of vehicle on-board equipment.
host transit vehicle status	Information provided to the ITS on-board equipment from other systems on the Transit Vehicle Platform.
host vehicle status	Information provided to the ITS on-board equipment from other systems on the vehicle platform. This includes the current status of the powertrain, steering, and braking systems, and status of other safety and convenience systems. In implementations where GPS is not integrated into the Vehicle On-Board Equipment, the host vehicle is also the source for data describing the vehicle's location in three dimensions (latitude, longitude, elevation) and accurate time that can be used for time synchronization across the ITS environment.
transit stop locations	The current geographic location and dimensions of transit stops. This flow may also include the road geometry in the vicinity of the stops as needed to support transit vehicle safety applications when arriving at or departing from stops.
transit vehicle operator display	Visual, audible, and tactile outputs to the transit vehicle operator including vehicle surveillance information, alarm information, vehicle system status, information from the operations center, and information indicating the status of all other on-board ITS services.
transit vehicle operator input	Transit vehicle operator inputs to on-board ITS equipment, including tactile and verbal inputs. Includes authentication information, on-board system control, emergency requests, and fare transaction data.
vehicle location and motion	Data describing the vehicle's location in three dimensions, heading, speed, acceleration, braking status, and size.
vehicle path prediction	The predicted future vehicle path of travel. This flow includes an indication of the future positions of the transmitting vehicle that can be used by receiving vehicles to support coordinated driving maneuvers and enhance in-lane and out-of-lane threat classification.
vehicle signage data	In-vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., local traffic and road conditions, restrictions, vehicle requirements, work zones, detours, closures, advisories, and warnings).

Basic Transit Vehicle	Transit Vehicle OBE	host transit vehicle status	This can include some sensitive data. However, other data, such as vehicle location and motion will then be broadcast. There also may be proprietary information included in this. DISC THEA believes this to be LOW: "sensor data is not confidential; harm should not come from seeing status."	This is used later on to determine whether a vehicle should request priority at an intersection. If this information is incorrect the vehicle may make false requests. All other flows that use the data from this flow have a MODERATE integrity requirement, therefore, this must also have a MODERATE integrity requirement. DISC: THEA believes this should be HIGH: "sensor data needs to be accurate and should not be tampered with."

Transit Vehicle OBE	Transit Management Center	vehicle location and motion	This data is intentionally transmitted to everyone via a broadcast. Much of its information content can also be determined via other visual indicators	Incorrect information could lead to the system not operating properly. If the system does not properly know where the vehicle is, it cannot make an accurate decision about whether there is going to be a pedestrian in the crosswalk that the vehicle is approaching. This can have a safety impact.	This data is required for the system to operate properly. If this data is not available, the system cannot give accurate warning information.

It would be possible for a person standing behind the driver to observe the information transmitted.	Some minimal guarantee of data integrity is necessary for all C-ITS flows. This entire application should not directly affect the drivers driving habits. The operator should still be slowing and stopping at yellow or red lights, along with observing all other driving regulations. DISC: Original V2I analysis classified this as LOW.	Even if the operator is not made aware of the signal preemption, the system should still operate correctly.

Transportation Information Center	Vehicle	vehicle signage data	Low	Moderate	Moderate
Transportation Information Center	Vehicle	vehicle signage data	This data is intentionally transmitted to everyone via a broadcast. It is meant to augment other signage data, and by definition is meant to be shared with everyone.	These signs are meant to augment other visual cues to the driver. They should be accurate, but any inaccuracies should be corrected for by other means.	These notifications are helpful to a driver, but if the driver does not receive this notification immediately, there should still be other visual cues.
Vehicle	Basic Vehicle	driver update information	Low	Moderate	Moderate
Vehicle	Basic Vehicle	driver update information	This information is all presented to the vehicle operator. Encrypting this information may make it harder to reverse engineer vehicle systems, and may defeat criminal tracking tools when the vehicle has already been compromised. Unless those scenarios are of concern to the operator or manufacturer, this can safely be set LOW.	Any information presented to the operator of a vehicle should be both accurate and timely. By definition this includes safety information, but given that the driver has other means of learning about most threats, it seems difficult to justify HIGH. If HIGH is warranted, it should apply to both availability and integrity.	Any information presented to the operator of a vehicle should be both accurate and timely.

Vehicle	Driver	driver updates	Not Applicable	Moderate	Moderate
Vehicle	Driver	driver updates	This data is informing the driver about the safety of a nearby area. It should not contain anything sensitive, and does not matter if another person can observe it.	This is the information that is presented to the driver. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as an oncoming vehicle or crossing safety lights.	If this information is not made available to the driver, then the system has not operated correctly.
