Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Work zones can give rise to significant costs, both to maintenance agencies as well as to road users. In this paper we focus on the optimal configuration of work zones on two-lane highways. While … [Read more...] about Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Optimal Design of Work Zone Median Crossovers
The use of temporary median crossovers in work zones allows for the closure of one side of a multi-lane roadway while maintaining two-way traffic on the opposite side. This process provides the … [Read more...] about Optimal Design of Work Zone Median Crossovers
