Investigating the Impact Factors of Night Construction for Urban Road Projects

Abstract

Construction work on urban roads often causes changes in the speed and trajectory of vehicles, resulting in serious congestion and traffic accidents. Construction work on urban roads also poses several energy, environmental and social problems. In this context, maintenance work is increasingly being carried out at night, when traffic pressure is relatively low, to minimize the adverse effects of road construction. This study uses a literature review and expert interviews to construct a model of the influencing factors of urban road construction at night containing 11 factors. A questionnaire is designed to investigate the road construction enterprises' agreement with these influencing factors. The results of the statistical analysis and factor analysis showed that the factors can be divided into two main factors: the competent factor and the objective factor. The objective factors of road construction have a significant impact on construction companies, which should pay more attention to the impact of road construction at night on construction and traffic. Air pollution and energy consumption are the least important factors for construction companies when considering whether to use night work as a method. The only way to carry out night work is to ensure the safety of construction workers, adequate lighting and a comprehensive traffic control plan.
