What is early, on-time and late (EOL)?

EOL is how we define On time performance (OTP). The number of times the closest matching bus heartbeat was detected early* at this stop, out of the total number of matched instances. 

*Early = 60 seconds or more ahead of schedule.

Average early time

Average time a matching bus heartbeat was detected early at this stop.

On time - by count and percentage

The number of times the closest matching bus heartbeat was detected at this stop between 60 seconds ahead of and 5min 59 seconds behind schedule, out of the total number of matched instances.

First stop count

The number of times the closest matching bus heartbeat was detected at this stop as the first stop on its trip, out of the total number of scheduled instances.

Last stop count

The number of times the closest matching bus heartbeat was detected at this stop as the last stop on its trip, out of the total number of scheduled instances. 

Timing points count

The number of times this stop was counted as a timing point for a bus passing it, out of the total number of scheduled instances. 

Late - by count and percentage

The number of times the closest matching bus heartbeat was detected late* at this stop out of the total number of matched instances.

* Late = 5 mins 59 seconds or more behind schedule.

Average late time

Average time a bus was late at this stop.

Not detected (Not observed)

The vehicle was not “seen” at the timing point

No data

No instances of heartbeats (real-time data) have been received to match a scheduled journey in the GTFS
