Fig 3. Simulation results of ambulance diversion (AD) strategy: Study II.
(a) The crowdedness indices (CIs) of ED1 to ED6 and the regional crowdedness index (represented as EDr) throughout a day resulted from implementing patient diversion rule 1. (b) The CIs of ED1 to ED6 and the EDr throughout a day resulted from implementing patient diversion rule 2. (c) The CIs of ED1 to ED6 and the EDr throughout a day resulted from implementing patient diversion rule 3. (d) The EDr resulted from the three AD strategies.
