How to map route_id from LIRR/MNR json API feed to line name?

[Александр Кочкарёв]

Hello!

For example, i get an alert like this:

       "alert": {

            "active_period": [

                {

                    "start": 1632506023,

                    "end": 1632507762

                }

            ],

            "informed_entity": [

                {

                    "agency_id": "LI",

                    "route_id": "5",

                    "transit_realtime.mercury_entity_selector": {

                        "sort_order": "LI:5:14"

                    }

                }

            ],

            "header_text": { ... },

            "description_text": { ... }

        }

And i want to match "route_id": "5" to some line name which i can see in https://new.mta.info page for Rails , like "Babylon", "City Zone", "Far Rockaway" etc.

Where can i get this mapping or route_id meaning information?

From the GTFS file (example here: https://openmobilitydata-data.s3-us-west-1.amazonaws.com/public/feeds/mta/86/20210927/original/routes.txt)

1 - Babylon

2 - Hempstead

3 - Oyster Bay

4 - Ronkonkoma

5 - Montauk

6 - Long Beach

7 - Far Rockaway

8 - West Hempstead

9 - Port Washington

10 - Port Jefferson

11 - Belmont

12 - City Zone

Thank you so much! All is clear now.

I've faced another trouble when try to match routes with lines.

I've got the latest gtfs.zip files for LIRR and MNR from https://openmobilitydata.org/

But there is some inconsistency with https://new.mta.info/ site.

1)  LIRR routes.txt has next record:

"11","","Belmont Park","2","60269E","FFFFFF"

But there no "Belmont Park" line at https://new.mta.info/ in Rail section.
Why? Is this line active?

2) MNR
On site i see next lines:

"Wassaic"

"Pascack Valley"

"Port Jervis" (i found in api feed that it matched to route_id "NJT:6")

but they are not listed in MNR routes.txt:

route_id,agency_id,route_short_name,route_long_name,route_desc,route_type,route_url,route_color,route_text_color

10,5,,MNR Shore Line East,,2,,555555,FFFFFF

11,2,,Haverstraw Ferry,,4,,009B3A,FFFFFF

12,3,,Hudson Rail Link(Spuyten Duyvil),,3,,009B3A,FFFFFF

13,3,,Hudson Rail Link(Riverdale),,3,,009B3A,FFFFFF

14,2,,Newburgh Ferry,,4,,009B3A,FFFFFF

3,1,,New Haven,,2,,EE0034,FFFFFF

4,1,,New Canaan,,2,,EE0034,FFFFFF

5,1,,Danbury,,2,,EE0034,FFFFFF

6,1,,Waterbury,,2,,EE0034,FFFFFF

1,1,,Hudson,,2,,009B3A,FFFFFF

2,1,,Harlem,,2,,0039A6,FFFFFF

What does it mean and how can i get route_id for this lines?

Will be glad to any advice.
