Interface: COTA Transit Fixed-Route Vehicles - COTA Fixed-Route Transit Management System
Architecture Flow Definitions
alarm acknowledge (Existing) Applicable ITS Standards
Confirmation that alarm was received, instructions and additional information for the alarm initiator, and requests for additional information.
alarm notification (Existing) Applicable ITS Standards
Notification of activation of an audible or silent alarm by a traveler in a public area or by a transit vehicle operator using an on–board device.
connection protection instructions (Planned ) Applicable ITS Standards
A request to hold at a specific stop for a specified time period to protect connections. This flow would also include subsequent adjustments to, or cancellation of, a hold request.
demand response passenger and use data (Planned ) Applicable ITS Standards
Data collected on board a demand response vehicle relating to the picking up and discharging of passengers.
transfer request (Planned ) Applicable ITS Standards
A traveler request for a transfer between transit routes, services, or modes. The request may also include preferences such as a need for extra connection time or connection protection in the event of a delay.
transfer status (Planned ) Applicable ITS Standards
Information indicating whether a requested transfer can be confirmed including specific information about the connection including fare payment information. Real–time updates are provided if the transfer status changes up to and including a reminder just prior to the transfer. In the event that a requested transfer is not feasible, alternatives including other transit, rideshare, and taxi options are provided.
transit schedule information (Planned ) Applicable ITS Standards
Current and projected transit schedule information used to initialize the transit vehicle with a vehicle assignment, monitor schedule performance, and develop corrective actions on–board.
transit stop locations (Planned ) Applicable ITS Standards
The current geographic location and dimensions of transit stops. This flow may also include the road geometry in the vicinity of the stops as needed to support transit vehicle safety applications when arriving at or departing from stops.
transit traveler information (Existing) Applicable ITS Standards
Transit information prepared to support transit users and other travelers. It contains transit schedules, real–time arrival information, fare schedules, alerts and advisories, and general transit service information.
transit traveler request (Planned ) Applicable ITS Standards
Request by a Transit traveler to summon assistance, request transit information, or request any other transit services.
transit user information (Planned ) Applicable ITS Standards
Information about individual transit users boarding a transit vehicle, used to track a user's progress on a scheduled transit trip.
transit vehicle loading data (Existing) Applicable ITS Standards
Data collected on board the transit vehicle relating to passenger boarding and alighting.
transit vehicle location data (Existing) Applicable ITS Standards
Current transit vehicle location and related operational conditions data provided by a transit vehicle.
transit vehicle measures. (Existing)
Transit vehicle status measured by on–board ITS equipment.
transit vehicle operator information (Existing) Applicable ITS Standards
Transit service instructions, wide area alerts, traffic information, road conditions, and other information for both transit and paratransit operators.
transit vehicle schedule performance (Existing) Applicable ITS Standards
Estimated times of arrival and anticipated schedule deviations reported by a transit vehicle.
vehicle situation data (Planned ) Applicable ITS Standards
This flow represents vehicle snapshots that may be provided by the vehicle to support traffic and environmental conditions monitoring. Snapshots are collected by the vehicle for specific events (e.g., when a sensor exceeds a threshold) or periodically and reported based on control parameters when communications is available. Traffic–related data includes snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control events. Environmental data may include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected.
vehicle situation data parameters (Planned ) Applicable ITS Standards
A request for vehicle situation data that includes parameters used to control the data that is reported and the flow of data reported by the vehicle. This flow identifies the type of data/snapshots that are requested and reporting parameters such as snapshot frequency, filtering criteria (data thresholds for reporting), and reporting interval.
