To study the design rationality of intersection and gateways, reduce traffic congestion and accidents, based on the function design conception, this paper took connected roads in Pearl River Delta urban agglomeration as research object, combined theoretical analysis and VISSIM simulations, analyzed the traffic characteristics, reasonable forms, traffic organization design methods in the intersections, as well as the locations and reasonable intervals of passageways. The results show that: length of left-turn lanes on city agglomeration connection roads can be 40 m to 100 m, while the length of right-turn lanes for acceleration or deceleration can be 40 m ∼ 60 m. When the distance between two gateways ranges is 800 m ∼ 900 m, the running speed will increase obviously and the longest queue length will decrease remarkably; But when it is over 900 m, the variation of running speed and queue length will change to be smaller. So the distance recommended value is 900 m - 1200 m.
