Bus signal priority is an important indicator of public transit metropolis construction, and it is also an indicator that many public transit metropolises are difficult to complete. Taking the intersection of Fenghe North Avenue and Changjiang Road in Nanchang City as an example, this study obtained the relevant basic data for priority design of bus signals through on-site shooting and investigation. This study proposes a total of eight designs for public transit active priority and passive priority. The model results show that prohibiting the left-turn can reduce the intersection delay. If the signal period length is reduced, the intersection delay can be further reduced. The pre-signal design can reduce the per capita delay of the intersection; It is more advantageous to combine the active priority and the passive priority than only have a single signal priority, and the per capita delay of the intersection is reduced by more than 50%. The research results have certain reference value for the construction of public transit metropolis.
