Pokey Awards Fall 2006 METHODOLOGY These awards are intended as a follow-up to the NYPIRG Straphangers Campaign four previous Pokey Award reports issued in 2002, 2003, 2004 and 2005. The methodology used by the campaign in this report is identical to the one used in 2005 .
Selection of Routes
Due to significant differences between route patterns of the Manhattan M14A and M14D, these routes were measured separately. In total then, our sample includes 23 local bus routes.
Bus Speed Measurement
Each route was measured with an actual trip in both directions , beginning with the first bus departing from a terminus after 12:00 noon. The return trip was made from the second terminus back to the first on the next bus available. During each trip, surveyors recorded to the second the amount of time taken from terminus to terminus in each direction. Timing began as each bus pulled out of the first stop and concluded immediately after stopping at the last. In our analysis, times were rounded down to the minute and converted to a fraction of an hour. Distances covered were measured to the nearest 1/100th mile using computer GIS software. Bus speeds were calculated by dividing the number of miles per trip by the fraction of the hour taken to cover that distance. For each route, the bus speed cited in this report is an average of the speeds calculated for each direction on the route. Below is an example of how this methodology was applied to a sample route, Manhattans M66.
Sample CalculationM66
Immediately following their eastbound measurement, surveyors boarded the next westbound M66 at its eastern terminus, East 67th Street and York Avenue. The trip began at 12:51:10 PM and concluded at 1:12:56 PM at the western terminus, West 66th Street and West End Avenue. The westbound trip represents a distance of 1.91 miles, which was covered over 0.35 hoursa speed of 5.5 miles per hour. This report cites an average of the west- and eastbound speeds on routes surveyed. For the M66, this speed works out to 4.7 miles per hour. news release | pokey award methodology | the unreliables methodology www.straphangers.org | www.nypirg.org |
