On two-lane, two-way highways, pavement resurfacing is usually done by closing one lane
at a time. Then, vehicles travel in the remaining lane along the work zone, alternating
directions within each control cycle. Such a work zone can be analyzed as a one-way traffic-
control system in which queuing and delay processes are analogous to those at a two-
phase signalized intersection. Efficient scheduling and traffic control through work zones
may significantly reduce the total cost. A model is presented for optimizing work plans …

Pavements on two-lane two-way highways are usually resurfaced by closing one lane at a
time. Vehicles then travel in the remaining lane along the work zone, alternating directions
within each control cycle. In an earlier work, Chen and Schonfeld developed a work zone
optimization model for two-lane highways with time-dependent inflows and no detours,
based on simulated annealing. In this paper, several alternatives are evaluated, defined by
the number of closed lanes and fractions of traffic diverted to alternate routes. The algorithm …
