J1: Twitter interface for travel.
J1 uses Twitter to obtain service status information for the Los Angeles County Metropolitan Transportation Authority trains, Metrolink and some Japanese private railways. After a 6 day outage, we have redesigned the interface to Twitter using their most recent API and we have resumed travel information on J1 and the (new) J1 Mobile App.
Twitter updates will be retrieved once per minute, 24 hours a day.
Metro and Metrolink updates will take place once per minute, 24 hours a day.
Japan updates will take place on the following schedule:
- 4AM~6AM (local time in Japan): every 5 minutes
- 6AM~8PM: every 1 minute
- 8PM~2AM: every 5 minutes
At this time, weekends will be on the same schedule as weekdays.
