Calculation of system evolution parameters under occasional congestion.
| Parameter | Situation | Lane 2 is occupied | Lane 3 is occupied | Lanes 2 and 3 are occupied at the same time |
| Road capacity | 1863.08 | 2013.85 | 538.46 | Traffic flow at breakpoints | 2433.14 | 2564.60 | 774.55 | Change rate of the flow when it is stable | −53.75% | −56.01% | −68.00% | Change rate of capacity when it is stable | 21.45% | 22.82% | 30.52% |
