With the rapid development of rail transit, traffic problems caused by open-cut metro construction have become increasingly prominent. In order to quantify the negative impact of subway station construction, taking a metro stations under construction in Chengdu as example, collected relevant data such as traffic flow, congestion time, speed during congestion and noise decibel value at metro construction intersection by field test. Through quantitative calculation, the negative effects of open-cut construction are monetized from four aspects: extra fuel cost, time delay cost, environmental pollution cost and fatigue cost. It is found that the social cost is as high as 20 million yuan per year. Based on the calculation results and the actual traffic situation in Chengdu, the corresponding measures to reduce social costs are put forward.
