Microscopic traffic flow models are a class of scientific models of vehicular traffic dynamics. In contrast to macroscopic models, microscopic traffic flow models simulate single vehicle-driver units, so the dynamic variables of the models represent microscopic properties like the position and velocity of single vehicles. ==Car-following models== Also known as ''time-continuous models'', all car-following models have in common that they are defined by ordinary differential equations describing the complete dynamics of the vehicles' positions and velocities . It is assumed that the input stimuli of the drivers are restricted to their own velocity , the net distance (bumper-to-bumper distance) to the leading vehicle (where denotes the vehicle length), and the velocity of the leading vehicle. The equation of motion of each vehicle is characterized by an acceleration function that depends on those input stimuli: : In general, the driving behavior of a single driver-vehicle unit might not merely depend on the immediate leader but on the vehicles in front. The equation of motion in this more generalized form reads: : 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「microscopic traffic flow model」の詳細全文を読む スポンサード リンク
