Using computer simulation modeling, this research assessed the effectiveness and response times when using a mobile safety system versus an emergency call box when reporting an emergency at Purdue University, West Lafayette's Engineering Mall area, attempting to answer the first question "What emergency call system is more effective: a mobile safety system or an emergency call box?" The second question asks "What emergency call system has a faster response time: a mobile safety system or an emergency call box?" A discrete event simulation model of the emergency call service is used. The outcome of the study was that the mobile safety solution resulted in being more effective than the emergency call box. This study shows that the arrival time to reach an emergency call box is a major factor in lowering the average effectiveness time when using an emergency call box to report an emergency. This study shows that the emergency call box results in an average overall faster response time when reporting an emergency versus using a mobile safety system. This study uses a simulation approach that produces a decision tool for campus security officials to assess emergency call systems effectiveness and response times on a college campus.
