Transit Management Center --> Transit Vehicle OBE:
transit vehicle operator authentication update
Definitions
transit vehicle operator authentication update (Information Flow): Results of authentication process or update of on-board authentication database.
Transit Management Center (Source Physical Object): 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 (Destination Physical Object): 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.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | Authentication information exchanged probably does not include PII, but even so it betrays actions that are otherwise not easy to observe and not designed to be observable. Attackers might use this information during the commission of a crime. | As this may be used as part of transit vehicle security processes, any corruption or manipulation of this flow could defeat those processes, impacting vehicle security. | There are likely onboard mechanisms for coping with a loss of availability, but if this flow is a critical part of transit security then it really should be protected at all costs. Possibly MODERATE. |
