“…IoT technology, as an extension of the network technology, can be associate with RFID (radio frequency identification), infrared sensors, global positioning systems, laser scanners and other sensing devices to provide real-time information (Cai et al, 2014;Chen, 2017;Cheng et al, 2018;Jiang et al, 2014;Li et al, 2013;Lai et al, 2017;Liu et al, 2017;Lu and Xu, 2018;Xu, He and Li, 2014;Xu, Xu, Cai, Xie, Hu and Bu, 2014;Xu et al, 2018). In order to achieve smart identification, positioning, tracking, monitoring and management, different devices and internet are connected to conduct information exchange and communication based upon the agreement, such as RFID technology, sensing and control technology, short-range wireless communications technology and general packet radio service GPRS technologies (Feng and Xu, 1996;Fang et al, 2014;Li et al, 2015Li et al, , 2018Qi et al, 2017;Zhai et al, 2016, Huang et al, 2016. They are employed to the areas where congestion, stampede and blockage occur, such as transfer channels, gates, stairs, etc.…”
