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 connected vehicle on-board equipment.
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.
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.

This data is broadcast and intended for general consumption. False information here could play havoc with an individual's schedule and cause inconvenience to users of transit services that received incorrect information. This data should be available through other means, but it will be more convenient if available. Depending on the implementation and other dissemination methods, this may be LOW.

This information could be of interest to a malicious individual who is attempting to determine the best way to accomplish a crime. As such it would be best to not make it easily accessible. If this is compromised, it could send unnecessary maintenance workers, or cause the appearance of excessive traffic violations, leading to further unnecessary investigation. A delay in reporting this may cause a delay in necessary maintenance, but (a) this is not time-critical and (b) there are other channels for reporting malfunctioning. Additionally, there is a message received notification, which means that RSE can ensure that all intersection safety issues are delivered.
Personal Information Device Connected Vehicle Roadside Equipment personal location Not Applicable High Moderate
This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. An incorrect locations message, could lead to a false warning or lack of warning. A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. DISC: NYC believes this to be HIGH if the data is used as part of Pedestrian-focused goals, but in other circumstances might be LOW and treated as informative information only. There are other visual indicators about the geofenced areas. PID users in dynamic environments (incident and work zones) should know when they are leaving a geofenced area. As long as they remain in the geofenced area, this information is not as necessary. Not all pedestrians will carry a personal information device, and the system should be able to operate without this information.
