Proof; Figure 2 illustrates Principle 1 using the information in Table 1. 49 for j = 1 and j = 2, respectively, the resultant headways are those required. The transition load is the one determined for the 8:01 departure, and is comprised of 20 minutes arrivals for j = 1, and 1 minute arrival for j = 2. Therefore (20/20) x 50 +(1/17) x 55 = 53 approximately. This transition load is not the exact average between d] = 50 and d2 = 55 since departures are made in integer minutes. 688 minutes, and inserting this value instead of 1 minutes in the above calculation yields a closer value to the exact average.
Figure 8 illustrates an example of two terminals and seven trips using the DH representation in part (i). Part (ii) shows how to reduce the fleet size using shifting tolerances of % time unit (forward or backward) where the shifts are shown with small arrows and the update DF is marked by a dashed line. Part (iii) shows how to apply only the URDHC procedure with DH times of 2 time units, and part(iv) presents a modified URDHC (mixed with the shifting) procedure. As can be seen in Figure 8(i) the fixed schedule without DH considerations requires 5 vehicles.
G. from the road supervisions) to support it. g. from APCs) it is possible to construct procedures to better match the timetables (departure times) with the variable demand. This and the next section provide such procedures. The Undergoing Principle of Procedure 2 The results of procedure 1 starts with the 7:20 and 7:40 departures for j = 1. 96 for j = 1 (as is shown in Table 1). This frequency aimed at 50 passengers per bus while considering the entire hourly max demand. 2 pass/min between 7:15 and 7:45 at the hourly max load point B.
