Modelling public transport corridors with aggregate and disaggregate demand

Traditional microeconomic modeling of public transport (usually a single line) has been based on aggregated demand description, that is, total ridership along a line and average journey length. In this paper we examine the advantages of having different levels of aggregation regarding demand information in order to explore improvements on the recommendations and conclusions obtained from classical microeconomic models. Thus, we establish the optimal conditions for the relevant decision variables (frequency and vehicle size) on a public transport corridor with inelastic demand, in cases where the demand data is only available at an aggregated level (at the level of an entire line, or ridership per direction of movement) as well as cases in which it is feasible to obtain more detailed information on the demand structure, like origin-destination matrices at the level of bus stops or number of passenger who board and alight each bus at each stop.
