To explore the relationship between traffic safety and efficiency and its influencing factors under specific types of weaving areas, this paper selects length of weaving area, ramp traffic volume, mainline traffic volume and interweaving flow ratio as influencing factors; conflict numbers and conflict rate as safety indicators; and delay and average speed as traffic efficiency indicators. Through the VISSIM simulation test, the test parameters were calibrated, and 38 orthogonal tests were designed. Range and variance analyses were conducted and the importance of each influencing factor on each index was obtained. The study found that for traffic safety and efficiency in the weaving area, the length of the interweaving and the ramp flow are the two most important factors; for traffic safety, the mainline traffic volume and the interweaving traffic ratio are of equal importance; for the traffic efficiency, the mainline traffic volume is more important than the interweaving traffic ratio.
