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.
Connected Vehicle Roadside Equipment	Field	'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices (i.e., Roadside Units (RSUs)) equipped with short range wireless (SRW) communications technology, as well as any other supporting equipment that leverage the RSU and are not described by other objects (e.g., a local roadside processor). CVRSE are used to send messages to, and receive messages from, nearby vehicles and personal devices equipped with compatible communications technology. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
Personal Information Device	Personal	The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.
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.
Traveler	Personal	The 'Traveler' represents any individual who uses transportation services. The interfaces to the traveler provide general pre-trip and en-route information supporting trip planning, personal guidance, and requests for assistance in an emergency that are relevant to all transportation system users. It also represents users of a public transportation system and addresses interfaces these users have within a transit vehicle or at transit facilities such as roadside stops and transit centers.
Traveler Support Equipment	Field	'Traveler Support Equipment' provides access to traveler information at transit stations, transit stops, other fixed sites along travel routes (e.g., rest stops, merchant locations), and major trip generation locations such as special event centers, hotels, office complexes, amusement parks, and theaters. Traveler information access points include kiosks and informational displays supporting varied levels of interaction and information access. At transit stops this might be simple displays providing schedule information and imminent arrival signals. This may be extended to include multi-modal information including traffic conditions and transit schedules to support mode and route selection at major trip generation sites. Personalized route planning and route guidance information can also be provided based on criteria supplied by the traveler. It also supports service enrollment and electronic payment of transit fares. In addition to the traveler information provision, it also enhances security in public areas by supporting traveler activated silent alarms.

Includes Functional Objects:

Functional Object	Description	Physical Object
Personal Trip Planning and Route Guidance	'Personal Trip Planning and Route Guidance' provides a personalized trip plan to the traveler. The trip plan is calculated based on preferences and constraints supplied by the traveler and provided to the traveler for confirmation. Coordination may continue during the trip so that the route plan can be modified to account for new information. Many equipment configurations are possible including systems that provide a basic trip plan to the traveler as well as more sophisticated systems that can provide transition by transition guidance to the traveler along a multi-modal route with transfers. Devices represented by this functional object include desktop computers at home, work, or at major trip generation sites, plus personal devices such as tablets and smart phones.	Personal Information Device
RSE Transit User Guidance	'RSE Transit User Guidance' uses short range communications to provide terminal or stop-specific guidance to transit user devices that assists users in finding the right stop and the right bus. Optionally, this object can collect the transit user location and planned itinerary so that tailored guidance can be provided.	Connected Vehicle Roadside Equipment
Transit Stop Information Services	'Transit Stop Information Services' furnishes transit users with real-time travel-related information at transit stops, multi-modal transfer points, and other public transportation areas. It provides transit users with information on transit routes, schedules, transfer options, available services, fares, and real-time schedule adherence. In addition to tailored information for individual transit users, it supports general annunciation and/or display of imminent arrival information and other information of general interest to transit users.	Traveler Support Equipment
Transit Vehicle On-Board Information Services	'Transit Vehicle On-board Information Services' furnishes en route transit users with real-time travel-related information on-board a transit vehicle. Current information that can be provided to transit users includes transit routes, schedules, transfer options, fares, real-time schedule adherence, current incidents, weather conditions, non-motorized transportation services, and special events are provided. In addition to tailored information for individual transit users, it also supports general annunciation and/or display of general schedule information, imminent arrival information, and other information of general interest to transit users.

If this flow is not available then stop requests won't be completed and the originator of the request is inconvenienced. Long term however, if this flow is generally not reliable then users are unlikely to use or rely on it. Should be MODERATE to instill confidence and encourage use.

General transit schedule information, as well as more specific "next stop" and similar information should be prompt and correct or users will lose confidence and not use the system. Also inconvenienced by the lack of correct and timely information. Impact is localized and limited however, so MODERATE and not HIGH.

Personal Information Device	Transit Vehicle OBE	transit user information	Moderate	Moderate	Moderate
Personal Information Device	Transit Vehicle OBE	transit user information	May contain the PII of the originator, which should be readable only by the intended recepient lest the originator's privacy be violated. If the implementation does not provide traveler identity, this may be reduced to LOW.	If this is compromised or corrupted, the user's needs may not be properly communicated or met. If this is forged, the transit provider may provide unnecessary services.	If this is not available, the user may not receive transit services offered, and as with other transit services may ceases using the system. While the immediate impact is LOW, long term impact is MODERATE due to user confidence issues.
Personal Information Device	Traveler	traveler interface updates	Not Applicable	Moderate	Moderate
Personal Information Device	Traveler	traveler interface updates	Personalized data that includes directions and guidance for an individual, but eventually evident anyway.	Should be accurate as the Traveler will be relying on this information for routing and related choices. Lack of accuracy will result in lack of confidence from the traveler as well as an unsatisfactory trip, leading to a negative feedback spiral.	Users expect their devices to work. If information is not presented to the operator, the relevant applications simply won't be used.

Transit Vehicle OBE	Transit Vehicle Operator	transit vehicle operator display	Low	Moderate	Low
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.
Transit Vehicle Operator	Transit Vehicle OBE	transit vehicle operator input	Low	Moderate	Low
Transit Vehicle Operator	Transit Vehicle OBE	transit vehicle operator input	This information is transmitted through systems on board the Transit Vehicle. 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.
Traveler	Personal Information Device	traveler input	Not Applicable	Moderate	Low
Traveler	Personal Information Device	traveler input	This data is informing the vehicle of operational information that is relevant to the operation of the vehicle. It should not contain anything sensitive, and does not matter if another person can observe it.	While public, information must be correct or travelers may make incorrect decisions with regard to their travel plans.	Information is available through other means, though depending on the location this might not always be the case, in which case this would be MODERATE.
