Reducing speed in and upstream of a bottleneck is believed to reduce the probability of breakdown and increase capacity. The FOSIM microsimulation model was applied to simulate the effects of reduced speed limits. A single on-ramp was modeled under various operating conditions. Results of the simulation experiments show that there is a trade-off between breakdown probability and queue length. Thus speed reduction creates a situation where either the probability of breakdown with a small queue length is high, or the probability of breakdown with a large queue length is small.
