The recommendations are based upon 45 hours of capacity counts at 33 different work zones between 1987 and 1991. These new data indicate average capacities for short-term freeway work zone lane closures from 3 to 1 lanes and from 2 to 1 lanes that are significantly higher than older values reported in the 1985 Highway Capacity Manual. A base capacity value of 1,600 pcphpl is recommended for all short-term freeway work zone lane closure configurations.
