*Principles

 


There is a need for a transit system that can carry a large number of passengers swiftly throughout an urban area.

Structuring the transit system around a row of berths enables a high-frequency, high-capacity passenger carrying service to be achieved.

A. Four-stage parallel structure

1) Sequential start of vehicles at several berths arranged in a row.

2) Sequential start of vehicles at several terminals arranged in a row.

3) Sequential start of vehicles at a several branch-lines arranged in a row.

4) Arrangement of the guideway with multiple lanes.

The branch-line structure makes a high-frequency service on the mainline possible.
The high-frequency service makes a large carrying capacity possible.
If 5-seater cars are used in place of 10-seater cars, then the capacity is halved.

B. The interchange structure for high-speed passing

The interchanges of a two level guideway are structured with left-turn ramps having a large radius by means of twisted ramps. This structure enables high-speed passing, and facilitates construction in urban areas, because of the small size of interchange that can be achieved.
