"This data will serve as an input to various studies required to assist in drafting a strategy for 2010 and beyond," the eThekwini Department of Communications said in a statement Thursday.
"This strategy will determine the planning of, and with the intention to improve, the city's transport system and infrastructure."
A representative sample of 15 000 households will be interviewed about their weekday travel habits.
A pilot survey consisting of 100 interviews has already been undertaken to test the questionnaire methodology.
The four sampled areas, with 25 interviews each are:
* Umnini, a Tribal Authority in the southern rural area;
* Chesterville, a formal township in the central urban area;
* Cato Crest, an informal settlement in the central urban area; and
* Durban North, a formal suburb in the central urban area.
Deputy Head of Strategic Transport Planning Logan Moodley, said he had positive feedback from the survey contractor, Delca Research, about the pilot survey.
The municipality indicated that residents were very cooperative considering that the interviews were done without prior arrangements due to the nature of the random sampling method.
"I am touched and encouraged by the enthusiasm of the residents who although were not immediately available to participate in the interview but made arrangements to be interviewed at an alternative time," Mr Moodley said.
The project team has undertaken an analysis of the pilot survey with input from the debriefing sessions with the interviewers.
A quality assurance process was taken which included a follow up telephonic review of the survey methods, understanding questionnaires with respondent's samples and a review of the survey results.
Subsequently, the project team has refined the questionnaire methodology and consolidated operational issues for the purpose of a full survey on 1 June.
