The situation of blockage on shared lanes was divided into four cases: right-turn movement not being blocked during the red, right-turn movement being blocked during the red, through movement not being blocked during the lag time, through movement being blocked during the lag time. Then the corresponding probability and capacity under four cases were calculated. The capacity model of shared right-turn lanes considering right turn on red and the lag green time of right-turn was proposed. The presented model was verified by using microscopic traffic simulation software VISSIM. Results showed that the simulated results accorded with the theoretical model. The capacity on the shared lane increases with the decrease of the lag time, and the capacity has a negative correlation with the proportion of turning movement, while has a positive correlation with the effective green time.
