The state is one of the most important variables of the vs | plus control. This variable defines how the traffic stream may be worked with. The value of the state can be divided into two areas:
The traffic stream is red:
|
0 |
The traffic stream is inactive. |
|
1 |
The traffic stream has intervention type 1 (intervention not permitted in stage transition). |
|
101 |
The traffic stream has intervention type 1 (intervention permitted in stage transition). |
|
2 |
The traffic stream has intervention type 2 (intervention not permitted in stage transition). |
|
102 |
The traffic stream has intervention type 2 (intervention permitted in stage transition). |
|
3 |
The traffic stream has intervention type 3 (intervention not permitted in stage transition). |
|
103 |
The traffic stream has intervention type 3 (intervention permitted in stage transition). |
|
4 |
The traffic stream has intervention type 4 (intervention not permitted in stage transition). |
|
104 |
The traffic stream has intervention type 4 (intervention permitted in stage transition). |
|
8 |
The traffic stream can be given green. |
|
9 |
The traffic stream was given green. |
The traffic stream has green:
|
10 |
The traffic stream has not yet reached the green time tgmin1. |
|
11 |
The traffic stream has exceeded the green time tgmin1. |
|
12 |
The traffic stream has exceeded the green time tgmin2. |
|
13 |
The traffic stream has exceeded the green time tgmax1. |
|
14 |
The traffic stream has exceeded the green time tgmax2 and there is still traffic. |
|
15 |
The traffic stream has no traffic, but can be extended further if necessary. |
|
16 |
The traffic stream has no traffic, cannot extend any further |
|
19 |
Special red command for the traffic stream. |
|
