A. Arrows indicate passenger flow on a two-way passenger conveyor belt system in the loading and unloading phase.
B. Cars are turned on free-running rub- ber wheels. When turn is completed, cars are accelerated to main belt speed in one direc- tion and decelerated before turn for ter- minal station in the other direction.
C. Main belts carry cars at express speed. At the next terminal in either direc- tion cars will be decelerated to unloading speed, then loaded and accelerated to high speed for the run to the next terminal point.
D. Accelerating and decelerating beds control speed changes. Consisting of power. ed rollers geared to increase or decrease speeds of cars in a fluid motion, accelerating beds receive cars from a loading belt and pass them to a main line belt at a higher speed, while decelerating beds receive cars from main line belts at high speed and pass them on to unloading belts at lower speed.
E. Moving sidewalks (passenger con- veyor belts without cars or seats) can be used to feed traffic from bus terminals or parking lots to loading and unloading sta- tions on the main system.
trailing edge of a car as it accelerates 24 mph per sec.
To go from the 12 mph of the loading platform to 15 mph on the main run requires about 5 sec, whether the car is empty or fully loaded, while the distance traveled is 64 ft. Decelera- tion is similar in concept and actually some power is regenerated for the rest of the system by the slowing down action of the cars.
In conventional mass-transit vehi- cles, passenger discomfort is caused by either vertical or lateral motion or a combination of the two. The cars on the Carveyor passenger conveyor sys- tem can develop neither vertical or lateral motion. They are brought up to speed at a constant rate of acceleration (24 mph per sec or 4 fps per sec) with- out disturbing fluctuations. The brak-
