Average Person Delay. This MOE is commonly adopted to reflect the performance of a roadway system. If the average person delay for the whole network was reduced by the SS-RTSP project, then we would be able to conclude a net benefit from the TSP system.
Average Person Delay. On the basis of the simulation model described in Chapter 7, we calculated average person delay from the simulation results. Delays for passengers in both transit vehicles and general purpose vehicles were included in the calculation. Table 8-5 shows calculated average delays per person at the test intersections for both the TSP on and TSP off conditions. As we can see in Table 8-5, the average person delay was reduced by the SS- RTSP system. Over all four intersections, the TSP system saved an average of 0.1 second for all passengers. Although the 0.1-second time saving seems marginal for each person, the overall benefit of more than 48 person-hours over a three-hour period (peak hours) is significant. This indicates a total peak-hour time saving of 96 person-hours (here we assume six peak hours per day) or 25,056 person-hours per year. This benefit was achieved with only 18 bus runs over the three-hour period. During the same time period, 5000 regular vehicles were generated. Given that the sample size for passenger cars was much higher than that for transit vehicles, the average person delay decreased by the SS- RTSP system was remarkable.

Average Person Delay. On the basis of the simulation model described in Chapter 7, we calculated average person delay from the simulation results. Delays for passengers in both transit vehicles and general purpose vehicles were included in the calculation. Table 9-5 shows calculated average delays per person at the test intersections for both the TSP on and TSP off conditions. In Table 9-5, the average person delay was reduced by the SS-RTSP system. Over all 13 intersections, the TSP system saved an average of 0.02 second for all passengers. Although the 0.02-second time saving seems trivial for each person, the overall benefit of more than 29.2 person-hours over a three-hour period (peak hours) for the whole corridor is noticeable. This indicates a total peak-hour time savings of 58.4 person-hours per day (here we assume six peak hours each day) or 31,171 person-hours per year. The overall person delay saved by the SS-RTSP system is remarkable. However, the reduced average person delay when TSP was on is not statistically significant from that when TSP was off at the p=0.05 level.
