Hi TejaswitaK,
Good, First & foremost you have to draw out an action plan as how to proceed on this. I would suggest the following action plan for you to pursue step-by-step towards your task on this chosen topic.
1. You have to short list name of Universities under which you wish to carry out this research;
2. Search various sites providing guidance for preparation of entrance exams of this u'sities and make a check-list of date of entrance exams;
3. Once you have materials on which questions will presumably be asked in the exams identify some those scholars already researching on this topic and/or who have already completed their respective Ph.D and consult them, take guidance for your preparations to be successfully qualifying in the entrance;
4. Immediately after the entrance results are out of all the entrances you appeared, select among them the most reputed u'sity and get you regd. to do the research for Ph.D.
5. Once the U'sity so regd intimate the name of faculty & guide under whom you have to carry out the research, you go to him/her seeking their guidance;
6. Finalise the title/topic in consultation with your guide and of the targetted group/institutions and also a time line breaking down activity wise & prepare a bar chart specifying days allocated for each activity and get it approved by your guide;
7. Prepare a questionnaire containing appx.100 questions in such a way those will provide enough data for completing your requirement which are your basis for drafting your thesis;
8. Now you are ready to commence your work - first, collecting the Primary data i.e. survey responses on a listed questionnaire from the targetted group/public/industry/institutions within a span of time provided in the chart;
9.When all the above in progress you should maintain your work-diary based on which you should prepare a progress report, preferably monthly or quarterly as may be necessary and submit to the u'sity thru' your guide;
10. After collecting enough responses on your questionnaire show them to your guide and obtain his/her advices/suggestions for dissemination/presentation, grouping of the
collected responses;
11. Prepare graphical presentation of the grouped responses in the form of suitable/appropriate plates, graphs, charts;
12. The above task will provide some key summation, throw some problems and suggestions;
13. Based on the above you have to write your draft thesis providing appropriate charts, graphs,photos interleaved, write your summary, over view and conclusions, suggestions in a manner as per the Ph.D course requirements and discuss with your guide for corrections & improvements to the draft.
14. The corrected draft now ready for submission to the U'sity.
The following link will show you some of the questions for preparation of your own questionnaire. You may down load them, amend/rewrite to suit your requirement.
Traffic Questionnaire - Market Research Survey
I think you are aware of the duration of the course, implications, expenses and stipend involved in undergoing a Ph.D degree. My opinion is the duration could last from a minimum of 4 yrs and might go to 10 yrs(worst case) and be prepared. It depends on the u'sity and the guide. You should also consult few other Prof./Reseachers from faculties who are right persons to guide you appropriately in your quest.
All the best.
