Through that survey, we built a comprehensive transportation analysis platform and played a role in policy development and planning. We now say that less than 5 kilometers of passenger cars travel less than 5 kilometers, which is the result of traffic survey and analysis. This has played a role in our efforts to develop bus priority and guide car travel.
