Table 1 Determination and optimization strategy for traffic spillover dissipation state.
Sg1i | Sg2i | Sr1i | Sr2i | Pi | State determination and optimization strategy |
|---|---|---|---|---|---|
0 or 1 | 0 | 0 | 0 | 1 | No traffic spillover occurs; spillover control is not required |
1 | 1 | 0 | 0 | 2 | Effectively dissipating traffic spillover occurs; spillover control is not required |
1 | 1 | 1 | 0 | 3 | Potentially non-dissipating traffic spillover occurs; spillover control is required, and the signal timing plan should be adjusted accordingly |
1 | 1 | 1 | 1 | 4 | Absolutely non-dissipating traffic spillover occurs; spillover control is required, and the signal timing plan should be readjusted |
