Structure of bifurvation and crossover site of guideway in guided vehicle transportation system

Structure of a bifurcation site and crossover site of a guideway in a guided vehicle transportation system in which a vehicle configured to travel on the guideway;

• the structure of the bifurcation site and crossover site of the guideway comprising:
• left and right roadbeds on which left and right traveling wheels of the vehicle,
• a depression formed between the roadbeds, and
• a guard rail made of a channel-steel having a U-shaped groove laid down on a surface of the depression along a center line between the roadbeds so that a top of the guard rail is level with surfaces of the roadbeds;
• wherein the vehicle includes
• automatic steering systems for steering front wheels and rear wheels respectively by means of actuators each being provided for steering the front and rear wheels;
• guard wheels in an underside of the vehicle rotatably in a lateral plane and received in the groove of the guard rail with ample clearances between the periphery of the guard wheel and the side walls of the groove of the guard rail being laid down along the center line of the guideway;
• a fail-safe mechanism constituted by the guard wheels and the guard rail;
• wherein
• a movable guard plate and driving means thereof are provided to switch a connection of the groove of the guard rail at a bifurcation thereof, and
• a movable plate and driving means thereof are pluggable or coverable each of openings of grooves of guard rails in a region where the guard rail crosses a roadbed so that the movable plate is moved to plug or cover the groove thereby preparing a flat surface level with the roadbeds.
