The invention relates to a mobile terminal-based judgment method of a travel manner. The method includes: acquiring moving speed and a moving trajectory of a monitored object in a travel time period through a mobile terminal carried by the monitored object; calculating a curvature radius of each curved portion in the moving trajectory; and judging the travel manner of the monitored object according to the above moving speed and moving trajectory. According to the method of the invention, the amount of required data is small, a calculation amount is small, judgment is simple and accurate, and travel manners of massive monitored objects can be conveniently and quickly judged in time. The method is especially suitable for large cities with populations of millions and even more than ten millions.
