Detailed Description
NYCT Subway extensions for the trip descriptor.
Member Data Documentation
| optional Direction NyctTripDescriptor::direction = 3 |
Uptown and Bronx-bound trains are moving NORTH.
Times Square Shuttle to Grand Central is also northbound.
Downtown and Brooklyn-bound trains are moving SOUTH. Times Square Shuttle to Times Square is also southbound.
EAST and WEST are not used currently.
| optional bool NyctTripDescriptor::is_assigned = 2 |
This trip has been assigned to a physical train.
If true, this trip is already underway or most likely will depart shortly.
Train Assignment is a function of the Automatic Train Supervision (ATS) office system used by NYCT Rail Operations to monitor and track train movements. ATS provides the ability to "assign" the nyct_train_id attribute when a physical train is at its origin terminal. These assigned trips have the is_assigned field set in the TripDescriptor.
When a train is at a terminal but has not been given a work program it is declared unassigned and is tagged as such. Unassigned trains can be moved to a storage location or assigned a nyct_train_id when a determination for service is made.
| optional string NyctTripDescriptor::train_id = 1 |
The nyct_train_id is meant for internal use only.
It provides an easy way to associated GTFS-realtime trip identifiers with NYCT rail operations identifier
The ATS office system assigns unique train identification (Train ID) to each train operating within or ready to enter the mainline of the monitored territory. An example of this is 06 0123+ PEL/BBR and is decoded as follows:
The first character represents the trip type designator. 0 identifies a scheduled revenue trip. Other revenue trip values that are a result of a change to the base schedule include; [= reroute], [/ skip stop], [$ turn train] also known as shortly lined service.
The second character 6 represents the trip line i.e. number 6 train The third set of characters identify the decoded origin time. The last character may be blank "on the whole minute" or + "30 seconds"
Note: Origin times will not change when there is a trip type change. This is followed by a three character "Origin Location" / "Destination Location"
The documentation for this struct was generated from the following file:
