Please I need help with Theories and concepts I can use for my theoretical framework in my masters research work on PROBLEMS OF INADEQUATE PARKING SPACE IN PUBLIC FACILITIES. Thanks.

Can you tell a bit more? Where is this research? Is it generally the problem? Also, so far, how far have you done your research and any preliminary thoughts/hunch/hypothesis? Give me some more so I can help you. Also, what is your discipline so I can advice on method.
