And that includes the time the bus is stopped at the Jamaica Ave stop and the Metropolitan Ave stop, even though those are not "between Jamaica Avenue and Metropolitan Avenue"?As Stephen described, a data point is collected every 30 seconds or so (with some gaps), and the distance from the next downstream stop is estimated by latitude and longitude. It's hard to gauge dwell time unless it's really long. For example, on 10/22/2014, bus 199 was 32.7 feet upstream of the Jamaica Avenue stop at 8:56:48; at the stop at 9:00:28, 9:01:00, and 9:01:31; and was next recorded 121.5 feet upstream of the Myrtle Avenue stop at 9:04:41. In my analysis, I tried to find a similar upstream distance from Jamaica Avenue and and Metropolitan Avenue as start and end points, so it includes dwell time at Jamaica and Myrtle but not Metropolitan. |
