Abstract
Humans are the most significant resources in the universe. Subsequently, people life is urgently desired to be protected against the natural disasters such as earthquakes in which modern technologies can play an essential role. This paper presents a study of modeling road network traffic (RNT) using data communication networks (DCNs) with the focus on earthquake disaster aiming to achieve safer evacuation. Five DCN models are proposed to represent the traffic analogy of the corresponding RNT cases, namely, speed-flow relationships, left turn effect, four-way cross section control, roundabout cross control, and cracked roundabout. Using the road network (RN) mapping parameters to data network (DN) equivalents in these five models, the DN solutions can be used to solve RN problems. The simulation results indicate a close traffic performance analogy in both RNT and data DCNs. The proposed mapping is verified using two statistic tests called t-test and analysis of variance (ANOVA). Consequently, DCNs can be exploited in managing a safer evacuation during natural disasters.
