How to get wide and detailed information about public transportation


While being on a public transportation, a few questions sometimes arise. For instance, movement of people is different over time, but why is the operation interval of a public transportation almost static over time?
In a similar manner, why is there no bus route that a lot of people really like to take? Are the public transportation schedule designer aware of the up-to-date transport demand of the entire city?
Is the electronic check-in and check-out system implemented for public transportation efficiently monitoring the transportation volume? We are seeking for the answers to these questions by utilizing smartphones. We are also trying to quantitatively study how much public transportation efficiency can be improved from our answers.
