Common use of On-Time Performance Clause in Contracts

On-Time Performance. Table 13 shows the 4 month averages for on-time performance for the 95 Express Bus Service. Figure 8 shows the overall trend line from January 2008 to April 2010. A trip is defined as late if the bus arrives at a scheduled stop more than 5 minutes after the scheduled time and early if it arrives more than five minutes ahead of schedule. It should be noted that these data represent the entire length of the 95 Express routes in both directions, as it was not possible to isolate the direction or the I-95 section of the routes. Also, the data is based on time-points along the route. Both Table 13 and Figure 8 show that the 95 Express Bus was already performing well, but there was also some improvement. Average on-time performance improved from 76% in 2008 to 81% in 2010. For the UPA evaluation, Miami-Dade Transit conducted occupancy counts once a month at the Golden Glades Park and Ride Lot. This lot lies southwest of Golden Glades Interchange where Highway U.S. 441 and State Road 9 converge. It provides parking for the Golden Glades Tri-Rail Station, Miami-Dade Transit, Broward County Transit, and Greyhound. For much of the evaluation period, the lot’s capacity was 1,007 spaces. Then in December 2009, 535 spaces were added increasing the capacity to 1,542. Table 14 shows the four- month average utilization figures for the Golden Glades Park and Ride Lot. Shortly after Phase 1A began in December 2008, lot utilization increased 15%. For the first half of 2009, the lot was operating at or over capacity. The 2009 Phase 1A transit report even speculated that the lot’s capacity was hampering further ridership growth on the 95 Express Bus Service. However, utilization went on a downward trend beginning in the second half of 2009 and continued through the rest of the year. Average utilization from January to April 2010 was 23% lower compared to 2009. Why did utilization drop between 2009 and 2010? At first glance, it would appear that declining ridership on Tri-Rail was the source. Table 15 shows that over the same time period that utilization dropped 23%, average weekday Tri-Rail boardings at Golden Glades Station dropped 17%. Avg. Lot Utilization 899 1,036 797 -23% Avg. Tri-Rail Boardings 2,709 2,681 2,213 -17% However, when we looked at more detailed month-by-month data, it does not appear that the decline in Tri-Rail boardings was the contributing factor. Figure 9 compares by month the average weekday boardings for Tri-Rail at Golden Glades Station to the vehicle counts at Golden Glades Park and Ride Lot. The boardings are shown in blue. The vehicle counts are shown in red. One will notice that from August 2009 forward Tri-Rail boardings were fairly level even as the number of cars using the park and ride lot fluctuated back and forth. For this reason, Tri-Rail is not the source of the decline in lot utilization. A more plausible answer is that some Broward County riders of the Route 95X switched to one of the three new routes because they can board them closer to home. When they switched routes, they switched park and ride lots too. Table 16 looks at ridership on just the Route 95X, which serves Golden Glades Park and Ride Lot. Ridership dropped 14% between 2009 and 2010. Avg. Lot Utilization 1,036 797 -23% Avg. Ridership for 95X 2,398 2,067 -14% When one looks at the month-by-month data in Figure 10, one sees a direct relationship between the average weekday ridership on the Route 95X and the utilization of the Golden Glades Park and Ride Lot. The ridership is shown in blue, and the vehicle counts for the parking lot are shown in red.
