| Functional Area: On-board Transit Fare Management |
- The transit vehicle shall read data from the traveler card / payment instrument presented by boarding passengers.
- The transit vehicle shall provide an image of all travelers which shall be used for violation processing of those who do not have a traveler card / payment instrument or whose transit fare transaction fails.
- The transit vehicle shall determine the traveler's travel routing based on the transit vehicle's current location and the traveler's destination.
- The transit vehicle shall calculate the traveler's fare based on the origin and destination provided by the traveler as well as factors such as the transit routing, transit fare category, traveler history, and route-specific information.
- The transit vehicle shall have access to the complete range of transit services (routes and schedules) that are available to the traveler.
- The transit vehicle shall provide a transit fare payment interface that is suitable for travelers with physical disabilities.
- The transit vehicle shall include a database on-board the transit vehicle for use in fare processing from which the fares for all possible trips within the transit operational network can be determined.
- The transit vehicle shall support an emergency fare structure overriding all other fares that can be activated during disasters, states of emergency or evacuations.
- The transit vehicle shall support the support advanced payments for tolls, and/or parking lot charges, and/or transit fares via the traveler card / payment instrument.
- The transit vehicle shall provide fare statistics data to the center.
|
| Functional Area: On-board Transit Security |
- The transit vehicle shall perform video and audio surveillance inside of transit vehicles and output raw video or audio data for either local monitoring (for processing or direct output to the transit vehicle operator), remote monitoring or for local storage (e.g., in an event recorder).
- The transit vehicle shall perform local monitoring of video or audio surveillance data collected inside of transit vehicles, and identify potential incidents or threats based on received processing parameters.
- The transit vehicle shall output an indication of potential incidents or threats and the processed video or audio information to the center along with the vehicle’s current location.
- The transit vehicle shall detect potential threats via sensors for chemical agents, toxic industrial chemicals, biological agents, explosives, and radiation.
- The transit vehicle shall detect potential threats via object detection sensors (e.g. metal detectors).
- The transit vehicle shall output an indication of potential incidents or threats and the processed sensor information to the center along with the vehicle’s current location.
- The transit vehicle shall accept sensor control data to allow remote control of the sensors.
- The transit vehicle shall monitor and output surveillance and sensor equipment status and fault indications.
- The transit vehicle shall accept emergency inputs from either the transit vehicle operator or a traveler through such interfaces as panic buttons, silent or audible alarms, etc.
- The transit vehicle shall output reported emergencies to the center.
- The transit vehicle shall receive acknowledgments of the emergency request from the center and output this acknowledgment to the transit vehicle operator or to the travelers.
- The transit vehicle shall be capable of receiving an emergency message for broadcast to the travelers or to the transit vehicle operator.
- The transit vehicle shall be capable of disabling or enabling the transit vehicle based on commands from the center or authentic inputs from the transit vehicle operator.
- The transit vehicle shall perform authentication of the transit vehicle operator.
|
| Functional Area: On-board Transit Signal Priority |
- The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
- The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.
- The transit vehicle shall send the schedule deviation data and status of priority requests to the transit vehicle operator and provide the capability for the transit vehicle operator to control the priority system.
- The transit vehicle shall prevent a priority request from being sent when the transit vehicle cannot use the priority (e.g., when the transit vehicle makes a passenger stop on the approach to an intersection).
|
| Functional Area: On-board Transit Trip Monitoring |
- The transit vehicle shall track the current location of the transit vehicle.
- The transit vehicle shall support the computation of the location of a transit vehicle using on-board sensors to augment the location determination function. This may include proximity to the transit stops or other known reference points as well as recording trip length.
