The invention discloses a stereoscopic bus road section road traffic organization design and intersection road traffic organization design system. A stereoscopic bus road section road traffic organization design system of the stereoscopic bus road section road traffic organization design and intersection road traffic organization design system comprises a stereoscopic bus dedicated rail, a median strip, a height-limiting portal frame, a lifting separator bar, a sedan car lane being below a stereoscopic bus, a road side lane, a stereoscopic bus detecting device, an abouchement lane and a lane signal lamp. A stereoscopic bus intersection road traffic organization design system comprises a stereoscopic bus intersection entrance channelization area, a lifting separator bar, a pre-signal lamp, a main signal lamp, a stop station, a height-limiting portal frame and an intersection exit area. According to the stereoscopic bus road section road traffic organization design and intersection road traffic organization design system, on the basis of reducing changes of existing road designing as far as possible, compared with independently-arranged bus dedicated lanes, road spaces are reduced, meanwhile, a stereoscopic bus runs by using spaces above a road, intersection road traffic organization design is conducted by combining with platforms, and the operation and service level of public traffic is improved.
