This paper analyzes mode choice behavior in different weather conditions, with population groups, on travel purposes and travel distances to support the formulation of weather responsive traffic management measures. Revealed and stated adaptation surveys are carried out with 400 respondents and 100 respondents, respectively. The survey shows that the rate of mode change due to adverse weathers is much smaller than the figure in developed countries. The major patterns of mode change are shifts from motorcycle to car or taxi, accounted nearly half of mode changes, thus causing severer traffic congestions. The mode choice modelling show travel time, travel cost, gender, income, specific jobs, motorcycle ownership, bus ticket holding, provision of weather information prior to the trip are significant factors to mode choice decision under bad weather conditions. The results suggest focusing on “avoid or reduce unnecessary mobility demand” and “improve public transport” measures.
