Interface: MTS Buses - MTS Transit Enforcement

MTS Buses to MTS Transit Enforcement Interface Diagram

Information Flow Definitions

alarm acknowledge  (Existing)  

Confirmation that alarm was received, instructions and additional information for the alarm initiator, and requests for additional information.

alarm notification  (Existing)  

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.

emergency acknowledge  (Planned)  

Acknowledge request for emergency assistance and provide additional details regarding actions and verification requirements.

emergency data request  (Planned)  

A request for additional information or a control command issued by the emergency response agency in response to an emergency request for assistance from a traveler.

emergency notification  (Planned)  

An emergency request for assistance that is automatically initiated by a vehicle or manually initiated by a vehicle occupant. The request includes call–back number, date, time, location, pre–event vehicle heading, vehicle make, model, model year, and fuel type, and crash severity indicators. Crash severity indicators include: airbags deployed, number of impacts, crash delta velocity, principle direction of force, and rollover indication. In addition, seatbelt restraint use, number of occupants, occupant location, and intrusion may be included. For commercial vehicles, this flow may also include freight equipment type (box, flatbed, trailer, container, etc.), type of cargo (refrigerated, non–perishable, liquid, etc.), hazardous material data, quantity of cargo, and cargo permits as applicable (hazmat, special routing permissions).

emergency notification relay  (Planned)  

The relay of a previously received emergency notification. This relay enables a connected vehicle that is passing within radio range of a vehicle in need of assistance to store the notification and then forward it to a public safety agency when communications is available. Multiple relays may be necessary in remote areas with infrequent traffic and spotty communications coverage. The relay includes all of the information included in the original emergency notification (see 'emergency notification') and relay–specific data that can be used to manage the relay. Relay–specific data may include the date and time of original emergency notification receipt and the number of times the message has been relayed.

secure area sensor control  (Existing)  

Information used to configure and control threat sensors (e.g., thermal, acoustic, radiological, chemical), object, motion and intrusion detection sensors. The provided information controls sensor data collection, aggregation, filtering, and other local processing.

secure area sensor data  (Existing)  

Data provided by threat sensors (e.g., thermal, acoustic, radiological, chemical), and intrusion, motion, and object detection sensors in secure areas indicating the sensor's operational status, raw and processed sensor data, and alarm indicators when a threat has been detected.

secure area surveillance control  (Existing)  

Information used to configure and control audio and video surveillance systems used for transportation infrastructure security in secure areas. The provided information controls surveillance data collection, aggregation, filtering, and other local processing.

secure area surveillance data  (Existing)  

Data collected from surveillance systems used to monitor secure areas. Includes video, audio, processed surveillance data, equipment operational status, and alarm indicators when a threat has been detected.
