Sensitivity Analysis and Optimization of Urban Roundabout Road Design Parameters Based on CFD by Hangyu Zhang, Sihui Dong, Shiqun Li, Shuai Zheng

“…There is a strong coupling relationship between the pressure of the maximum pressure extreme point in the ring and the radius parameters of the outer ring. According to the optimal scheme of road parameters, that is, when the parameter set (inlet angle/°, number of lanes, outer radius/m) meets (35.4, 5, 65), the pressures of the feature points decrease by 34.1%, 38.3%, and 20.7%, respectively, which has a significant effect on alleviating the pressure in the intersection. …”
