Title: Control method for signal
Inventor: NISHIDA YOSHIKO
IPC: G08G1/08
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To permit a shuttle bus to smoothly travel a crossing by shortening the lighting time of a 'red' signal for necessary time in the case of a 'red' signal when a first sensor on this side of the signal at the crossing detects that the shuttle bus arrives at the crossing in specified time bands in the morning and evening. SOLUTION: Sensors 5a-5h detecting a shuttle bus detect specified signals emitted from the shuttle buses 6a and 6b. Detection signals 7a-7h outputted from the sensors 5a-5h are inputted to a control machine 4. If a signal 3c is 'red' when the first sensor 5a detects the shuttle bus 6a, the signal changes from 'red' to 'green' before the shuttle bus 6a reaches a crossing 2 and the shuttle bus 6a smoothly passes the crossing 2 in a first case. In a second case, the shuttle bus 6a temporarily stops on this side of the crossing 2 until the signal changes from 'red' to 'green' but the signal waiting time of the shuttle bus 6a is shortened in the specified time band when roads are likely to be congested.
