Building of Urban Emergency Road Network and Seismic Reliability Research Abstract Earthquakes have always been disasters to the human being with great loss of lives and personal injuries which destructive influence the disaster-affected area. , Nevertheless the increasingly urban size lead to the over dependence of the life line system such as water and power supply, transportation and communication system while the occurence of earthquake may cause the afunction of the city life line system. The urban transportation system not only plays a vital important role of city function in daily life but in earthquake rescue work. The integrity and reliability of the transportation system should be addressed to ensure its function in carrying out the emergency rescue work to minimize the disaster loss. Due to the profound influence of urban transportation system,the need to enhance our knowledge of it has greatly risen. A better comprehension of this issue is quite necessar . y Most of the previous investigations have been performed on individual structures such as roads and bridges. However, less attention has been given to the entire transportation system. This paper, based on the privious work have been done by other researchers, mainly focuse on the arterial road whi
