I need the Data Collection methods available to estimate the demand for curb pickup/drop-off zone, bicycle parking facilities, and car parking at a particular station.
The best way to collect such data is to use questionnaire and interview methods. Also, in the current situation, it is preferable to use an online forms.
Field trips with observation can help you manually collect observation data. I once advised a student to collect data on parking conditions for bike sharing in a Chinese city. Of course, if you want to know the demand for bike sharing, you probably need to do questionnaire survey for pedestrians and users of bike sharing.
