The average desired velocity of the drivers has been assumed to be proportional to the instantaneous velocity by M ndez and Velasco when a alternative model was proposed. Based on this postulate, the desired velocity of a single driver delineates to be proportional to the local instantaneous velocity in this paper, which is a property of aggressive drivers who all want to drive with the maximum velocity. However, the deriver does not occupy this aggressive characteristic all the time.

基于M ndez 和Velasc关于司机平均期望速度与瞬时速度成比例的假设，认为个体司机的期望速度与其局域瞬时速度成比例，期望以更大的速度行驶，然而并非所有的司机都具有这样的进取特性，为了抑制司机这样的进取特性，引入适应性公式来近似表达单个司机期望速度随时间的变化率。
