Abstract

Commuter Train is one of the facilities that must be managed properly, economically and efficiently in accordance with the principles of Facility Asset Management. The availability of infrastructure and vehicles for this facility is adjusted based on passenger demand. This requires sufficient knowledge on the travel behavior characteristics, ie different composition proportion. Characteristics require the appropriate formula to calculate the minimum sample size, especially for the proportion cases of pq, pqr, pqrs etc. Therefore a research for Sample Calculation Method for the Travel Behaviour Survey for Commuter Train is needed. A literature study was employed for this search. This is important because the calculation method for the minimum sample size for proportions pq exists, but for the proportion of pqr, pqrs etc do not yet exist. The results of the study can be conveyed that the SR method is the most appropriate method for calculating the minimum number of samples for the case of the proportion of pqr, pqrs, pqrst etc. Besides, the SR method also follows the MAECCL principle and has a smaller error value than the Goodnees of Fit method.
