Traffic is an important economic and social activities in urban area, and its congestion tends to be a bottleneck for their activities and economic developments, especially in developing countries. Heavy rainfall and urban flood are factors which generate or enhance the traffic congestions in urban area. Bangkok, our target city, has been under a rapid economic growth in last decades and the traffic congestion have been one of important and urgent social issue through the increasing population and economic activities. This study aims to analyze the impacts of urban flood and effects of adaptation measures on the traffic flow in Bangkok with connecting rainfall/floods and probe data which obtained from a large number of vehicles in motion through communication networks. In addition, we evaluated the effectiveness of adaptation measures to reduce the impacts of urban flood on traffic by applying the connected flood and traffic models to several adaptation scenarios.
