- Step 4 The traditional traffic control signal lights in other directions of an entrance road that intersects with an entrance road will work as a green light between 210-240;
- the working situation of the double traffic control signal group is as follows:
- the traffic control signal lights of a certain direction in a certain direction are between 60-120, that is, a period of 30 seconds before the end of the first step of the green light for the green light to work;
- the double traffic control signal lights of an entrance road in a certain direction that intersect with an entrance road are between 90-150 hours, that is, a period of 30 seconds before the end of the second green light for the green light work;
- the dual traffic control signal lights in other directions of an entrance road are between 120-180, that is, the green light works for a period of 30 seconds before the third step of the green light ends;
- the double-sided traffic control signal lights in other directions of an entrance road that intersects with an entrance road are between time 150-210, gp.
- the green light works for a period of 30 seconds before the end of the fourth step green light; and the above steps are repeated. .
- the green light duration of the dual traffic control signal and the green light duration of the traditional traffic control signal are generally intended to drive in a certain direction in the above dual traffic control method
- the number of vehicles designated as feasible lanes on the entrance road is between 0.6-1 times the ratio of the number of vehicles designated as feasible lanes on the entrance road in the traditional traffic control method.
- the invention is not limited to the embodiments shown here, but according to the widest scope defined by the appended claims.
