The present research work is concerned with most appropriate and desirable sizing and location of Bus Depots or Garages and their spatial dispersion in a given region to meet the travel requirements of the people while providing the highest operational efficiency of the Transport Organisations. The proposed approach is formulated in 3 Modules.
Module-I present the quantification procedures of the short and long distance bus travel. The long distance travel between the identified traffic zones is proposed by Internal Volume Forecasting Module employing link Bus Volume data obtained through conductor's Statistical Returns. The demand for short distance travel within a zone is proposed by developing  relationship between the socio-economic and demographic indicators and the per capita trip rate of the people of the delineated sub-zones.
Modules-II present the procedure to asses the required number of buses to meet the long and short distance travel as established in Module-I.
Module-III provides a procedure to identify the candidate location for depots based on the hierarchical trip generation and by determining ideal combination of locations minimising the total cost of operations, through an optimisation program. As there are gaps between the module attempting to explain the travel behaviour and those observed in reality, sincere efforts are required to study the micro level interfacing based on accurate decumentation procedures at depot level on cost of operation
