Common use of Average Person Delay Clause in Contracts

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.
