In order to study the dynamic decision making processes of travelers, based on decision field theory(DFT), automobile travelers' microcosmic and macroscopic dynamic decision making behavior under multiple attribute are studied. The basic model of DFT is analyzed, and travelers' dynamic decision making scene and frame are constructed. Historical travel time, forecast travel time and comprehensive time of the both are considered as route attributes, and calculation method of attention weight matrix is produced according to the difference of attributes and actual travel time. An example is studied, and we find that,freedom travel time is the primacy factor influencing route choice result, travelers rely on route attributes intensely, and preference reversal exists during the decision making, which denotes decision making is continuously changing with the decision time and travelers route choice is the result of time accumulating.
