在2014年和2015年朝觐期间，进行了一项实验性活动，以测量克尔白附近地区的行人流量。使用了高分辨率视频和照片。空间被划分为10平方米的区域。行人被计数，速度从视频剪辑测量。结果是令人惊讶的：在非常高的密度区域的速度增加，这也意味着增加的通量。这一区域的通量（超过8微粒子/平方米）达到超过3.5微粒子/米/秒的数值，比以前在走廊和通道中更“标准条件”下记录的通量高得多。
An experimental campaign was undertaken to measure the pedestrian flow in the region close to the Kaaba during the Hajj pilgrimages of 2014 and 2015. High resolution video and photographs were used. The space was divided into areas of 10 sqm. The pedestrians were counted, and the velocity measured from video clips. The results were surprising: the velocity in the very high density region increases, which implies also an increase of the flux. The flux in this region (with more than 8p/sqm) reaches values that exceed 3.5 p/m/sec, much higher than previously recorded under more `standard conditions' in corridors and passages.
