Those values represent three different options for converting the existing fare into a
distance-based fare. For example, the current average trip distance on Corridor I is
roughly 9.5 kilometers. Rp.2000 + (9.5 x 50) = 2500, Rp. 1500 + (9.5 x 100) = Rp.2450
(rounded to rp.2500), Rp. 1000 + (9.5 x Rp.160 = Rp.2520 (rounded to Rp.2500).
Changing the fare to a distance-based fare will of course change the average trip distance
of the passengers captured by the system, so the revenue impacts have to account for this:
The following table presents the results compared with actual fare system, for morning
peak hour. The operating costs have been calculated with Rp6500 per kilometer.
min. fare variable fare collected average running operating
Rp. Rp./km demand fare USD distance km cost USD gain USD
2500 0 4337 1205 9.53 660 476 728
2000 50 4401 1223 9.29 660 477 746
1500 100 5627 1458 8.51 781 564 894
1000 160 6675 1595 7.69 851 615 980
With a flat fare of Rp.2500 but with some optimization of the bus service in the corridor,
some modest increases in profits could be achieved. With a minimum fare at Rp1500 and
even more at Rp1000, the total demand increases, respectively 30% and 50%, catching
more short trips and less long trips. The trip renovation factor (the number of people
getting on and off the buses) on the line is higher, and hence the system is more
profitable. The total revenue increase of 20% and 30%, is lower than the increased
demand due to the loss of revenue on shorter trips, and the shorter average trip distances.
The bus frequency would need to be adapted to the change in demand structure, so the
running kilometer and operating costs also increase, but the gain (collected fare-operating
cost) is positive.
Even in the best scenario, the bus frequency is inferior to 60 bus/hour, it means it is in
theory compatible with the actual design of the corridor. But since the operation is not
optimized today, some improvement in regularity and boarding time are necessary to
absorb the additional demand.
When all the tree corridors are in operation, however, the situation will change, and the
distance-based fare considered differently. The first two options (Rp1500+Rp70/km and
Rp1000+Rp110/km) are calculated based on the average distance with flat fare. The third
one offers a fare discount for long trips in relation with the average flat fare.
