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.
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 Operations Personnel	Center	'Transit Operations Personnel' represents the people that are responsible for fleet management, maintenance operations, and scheduling activities of the transit system. These different roles represent a variety of individuals in the transit industry. Within the transit industry the person responsible for fleet management is known by many names: Street Supervisor, Starter, Dispatcher, Supervisor, Traffic Controller, Transportation Coordinator. This person actively monitors, controls, and modifies the transit fleet routes and schedules on a day to day basis (dynamic scheduling). The modifications will take account of abnormal situations such as vehicle breakdown, vehicle delay, detours around work zones or incidents (detour management, connection protection, and service restoration), and other causes of route or schedule deviations. Transit operations personnel are also responsible for demand responsive transit operation and for managing emergency situations within the transit network such as silent alarms on board transit vehicles, or the remote disabling of the vehicle. In addition the Transit Operations Personnel may be responsible for assigning vehicle operators to routes, checking vehicle operators in and out, and managing transit stop issues. This object also represents the personnel in the transit garage that are responsible for maintenance of the transit fleets, including monitoring vehicle status, matching vehicles with operators, and maintenance checking of transit vehicles. Finally, it represents the people responsible for planning, development, and management of transit routes and schedules.
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.

Includes Functional Objects:

Functional Object	Description	Physical Object
Transit Center Operator Assignment	'Transit Center Operator Assignment' automates and supports the assignment of transit vehicle operators to runs. It assigns operators to runs in a fair manner while minimizing labor and overtime services, considering operator preferences and qualifications, and automatically tracking and validating the number of work hours performed by each individual operator. It also provides an exception handling process for the operator assignment function to generate supplemental operator assignments when required by changes during the operating day.	Transit Management Center
Transit Center Vehicle Assignment	'Transit Center Vehicle Assignment' assigns individual transit vehicles to vehicle blocks and downloads this information to the transit vehicle. It also provides an exception handling process for the vehicle assignment function to generate new, supplemental vehicle assignments when required by changes during the operating day. It provides an inventory management function for the transit facility which stores functional attributes about each of the vehicles owned by the transit operator. These attributes permit the planning and assignment functions to match vehicles with routes based on suitability for the types of service required by the particular routes.	Transit Management Center
Transit Garage Maintenance	'Transit Garage Maintenance' provides advanced maintenance functions for the transit property. It collects operational and maintenance data from transit vehicles, manages vehicle service histories, and monitors operators and vehicles. It collects vehicle mileage data and uses it to automatically generate preventative maintenance schedules for each vehicle by utilizing vehicle tracking data. In addition, it provides information to service personnel to support maintenance activities and records and verifies that maintenance work was performed.	Transit Management Center
Transit Vehicle On-Board Maintenance	'Transit Vehicle On-Board Maintenance' collects and processes transit vehicle maintenance data on-board the vehicle, including mileage and vehicle operating conditions. This maintenance information is provided to the management center and used to schedule future vehicle maintenance and repair.	Transit Vehicle OBE
Transit Vehicle Schedule Management	'Transit Vehicle Schedule Management' monitors schedule performance and identifies corrective actions when a deviation is detected. It provides two-way communication between the transit vehicle and center, enabling the center to communicate with the vehicle operator and monitor on-board systems.	Transit Vehicle OBE

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.

Transit Management Center	Transit Vehicle OBE	transit schedule information	This information is not sensitive. It is generally made public, to support transit system functionality.	This data contains the vehicle assignment. It should be accurate, and not easily modified. However, the bus drivers will have some knowledge about what a reasonable configuration is, and should be able to notice any unusual configurations, such as all busses being a #27.	This information is necessary for the TSP to work correctly. A few missed messages will not have a large impact.

Such information could be used as part of damage assessment or target identification.	This needs to be accurate to properly schedule maintenance activities (for the basic maintenance data items) and to properly respond to warning indicators. If corrupted or unavailable, there could be a significant repurcussion for the vehicle and by extension, the vehicle operator.

Transit Vehicle OBE	Transit Vehicle Operator	transit vehicle operator display	This should not include any sensitive 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. The operator should be using the traffic lights to influence their decision about whether or not to stop, not the display.

Even if the vehicle were compromised and these communications monitored, most of this information is directly observable.	Some minimal guarantee of data integrity is necessary for all C-ITS flows. If this is compromised, it could result in an incorrect signal priority request, which has minimal impact. DISC: Original V2I analysis classified this as LOW.	A delay in reporting this may result in a signal priority request not going through, which has minimal impact.
