Time and cost based public transportation network modelling for transportation decisions: Istanbul case

This research is conducted to provide a methodlogy that will help planners, with the best way, in understanding the passangers' expectations and guiding authorities to meet the expectations of public transportation users where "sustainable public transportation services" have great importance. Today, it is very critical to understand the market's expectation. It is blatant that the public transportation systems' attractiveness will increase if the passengers' priorities are understood properly. In this research, it has been shown that the public transportation systems' demand prediction could be modelled with the methods such as Customer Expectation Surveys, Data Minig, and Mathematical Methods besides the expectations of public transportation users are handled appropriately. The public transportation systems' requirements in strategic planning and operation planning phases can be met with this studies' outputs of this study.
