| Abstract: | Since the projects requiring setup of temporary construction crossings on urban expressways are more and more, the construction opening should be studied in detail so as to guarantee smooth operation of the traffic of urban expressways. Aiming at principal ＂八＂, ＂X＂ and ＂∞ ＂ types of construction openings on expressways, this paper analyzes influences of each type on traffic capacity and traffic safety of urban expressways and applicable topographic conditions, and presents computing methods for influences on traf- fic capacity and security countermeasures, providing a reference for construction openings of expressways in the future. |
