Identify the causes for a phenomenon

Hi everyone. I would like to investigate the relationship of different factors to a phenomenon.

Saying I have traffic accidents (1 or 0) with related data at the same time and place e.g. traffic condition, weather, speed deviation, time-of-the-day, etc. How can I tell if those factors are significantly affected the traffic accidents ? And do the factors need to be independent with each other ?

Thank you very much. Your suggestions would be highly appreciated !
