SU15: Vulnerable Road User Device Transition Support

This service package supports the transition of a device used by a vulnerable road user (VRU) when they change from one mode in which they are vulnerable - walking, cycling, using a wheelchair, etc., to one in which they are less vulnerable, e.g., riding or driving a car, truck, emergency vehicle, transit vehicle, etc. This also supports the transition back to a more vulnerable mode. This service package represents a scenario where an aftermarket carry-in device, the PID, is carried into a vehicle that is already equipped with one of the Vehicle OBE implementations. In this scenario, there are two different devices with possibly two different radios and two different user interfaces that must be coordinated to avoid interference or conflicts.

Includes Physical Objects:

Physical Object Class Description
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.
Personal Personal The 'Personal' physical object is used to model core capabilities that are common to more than one physical object in the 'Personal' class. It provides the general executive, management, and utility functions that may be shared by different types of personal devices.
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.
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, 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
Personal Device Coordination 'Personal Device Coordination' coordinates with the vehicle on-board equipment (Vehicle OBE), micromobility vehicle (MMV) OBE or similar vehicle class equipment so that the PID for the traveler is not broadcasting conflicting information or is interfering with the OBE for the vehicle that the traveler is traveling on. Personal
Vehicle Device Coordination 'Vehicle Device Coordination' coordinates with the personal information device (PID) to transition between modes when the device used by the traveler or personnel no longer needs to broadcast safety and other information as well as when it is time to transition back to the personal device. This function also supports cases in which the PID will serve as the proxy for the vehicle onboard equipment and will act as a bridge to provide the vehicle's status and operating conditions to the PID. Vehicle

Includes Information Flows:

Information Flow Description
device configuration coordination A handshake between two different devices in the same vehicle or conveyance so the devices don't interfere with each or send conflicting information. This coordination may result in a personal information device (PID) carried by a traveler not transmitting its current location while on board vehicle, a transit vehicle, or a micromobility vehicle transmitting its vehicle profile and current location. For example, in the carry-in scenario, the personal device might go into a 'quiet' mode when carried into the vehicle that is already equipped with an integrated system that can broadcast safety messages.
driver input Driver input to the vehicle on-board equipment including configuration data, settings and preferences, interactive requests, and control commands.
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.
traveler input User input from a traveler to summon assistance, request travel information, make a reservation, or request any other traveler service.
traveler interface updates Visual or audio information (e.g., routes, messages, guidance, emergency information) that is provided to the traveler.

In order to participate in this service package, each information flow triple should meet or exceed the following security levels.

Information Flow Security
Source Destination Information Flow Confidentiality Integrity Availability
Basis Basis Basis
Driver Vehicle driver input Moderate High High
Data included in this flow may include origin and destination information, which should be protected from other's viewing as it may compromise the driver's privacy. Commands from from the driver to the vehicle must be correct or the vehicle may behave in an unpredictable and possibly unsafe manner Commands must always be able to be given or the driver has no control.
Personal Traveler traveler interface updates Not Applicable Moderate Moderate
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.
Personal Vehicle device configuration coordination Low High Moderate
Unlikely that any personal or not observable information is included here. Misconfiguration could cause a malfunction or lead to undesireable vehicle behavior. Will only affect the one vehicle, but could be dangerous to the MMV operator. Service cannot operate without this flow, and there is no alternative integrated solution. Listed as 'MODERATE' and not 'HIGH' only because loss of these services would be inconvenient and disadvantageous, particulary to vulnerable road users, but not catastrophic.
Traveler Personal traveler input Not Applicable Moderate Low
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.
Vehicle Driver driver updates Not Applicable Moderate Moderate
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.
