The existence of urban "dead end road" seriously affects the travel of citizens, hinders the road microcirculation and restricts the function of urban road network. There are many "dead end roads" with the multi-type causes in the central urban area of Dongying, which are mainly divided into "T"-type roads, unconnected roads and variable roads so as to seriously restrict the development of urban traffic. The connection of "dead end road" is a necessary measure to promote the microcirculation of urban roads and speed up the high-quality development of Dongying City. The research results have the important practical significance to provide the "Dongying Experience" for the research of "dead end road".
