Transit Time Match. As defined in Section 4.1, transit time match refers to the absolute difference between the actual transit arrival time at the timing point and the scheduled arrival time. The test corridor had seven bus stops, and six were affected by the TSP system. The average transit time match results at these bus stops are shown in Table 8-2. We calculated the arrival times of transit vehicles on the basis of TSP reader logs. The first three bus stops in the table are eastbound, and the others are westbound. Table 8-2 Time Match at Bus Stops in the Phase One Test Stop 197 Stop 189 Stop 196 Stop 1101 Stop 1573 Stop 1575 TSP Off 10′12″ 7′36″ 7′54″ 9′42″ 12′24″ 10′12″ TSP On 8′06″ 7′18″ 6′30″ 9′18″ 9′00″ 9′12″ The transit time match results showed that when TSP was on, transit coaches were more reliable at each bus stop. The increase of on-time performance varied from 18 seconds to 3 minutes and 24 seconds, or 3.9 percent to 27.4 percent, in comparison with the scenario in which TSP was off. The overall average improved time match at all the stops was 93.6 seconds, or about 16.3 percent in comparison with the scenario in which TSP was off.
Transit Time Match. The calculated TTM values are summarized in Table 9-2. The results show that transit vehicles would arrive at bus stops with reduced variability when the TSP system was on. The reduction in travel time variability varied from location to location, with a maximum reduction of 5 minutes and 51 seconds at stop 1013, located near the 220th Street intersection. The average improvement in transit time matched for all the bus stops was 15 seconds, or about 6 percent, in comparison with the scenario when TSP was off.
