Chen, T; Hu, H and Zhu, F (2020) Developing a hierarchical road layout method for large-scale construction site. Journal of Construction Engineering and Management, 146(9): 04020115, ISSN 0733-9364
Abstract
Large-scale construction projects that unify multiple subprojects and cover a large site area have been increased by rapid urbanization. Frequent traffic accidents have occurred inside these construction sites, which highly requires a reasonable road system to prevent traffic problems from the planning level. To address the research gap in modeling road layout for large-scale construction projects, this paper develops a hierarchical road layout method. Specifically, the method is established in three levels to distinguish the traffic demands inside and outside subprojects. Permanent roads are reconstructed to form a basic road network for the three road levels. Two optimization models are established to arrange nodes and links on the basic network. Preliminary evaluation results of a tourist resort project show that the proposed method can improve efficiency and safety performance. Further, the scenario analysis proves the feasibility in other types of large-scale projects. This primary investigation initially considers road hierarchy and utilization of permanent roads. Hopefully, it will enhance the traffic performance of large-scale projects and inspire more concerns on the traffic planning at preconstruction stage.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
