Fig 4. Simulation results of ambulance diversion strategy: Study III.
(a) The crowdedness indices (CIs) of ED1 to ED6 and the regional crowdedness index (represented as EDr) throughout a day resulted from the strategy of accepting ambulatory patients. (b) The CIs of ED1 to ED6 and the EDr throughout a day resulted from the strategy of diverting ambulatory patients without giving advices. (c) The CIs of ED1 to ED6 and the EDr throughout a day resulted from the strategy of diverting ambulatory patients with appropriate advices. (d) The EDr resulted from the three patient diversion strategies.
