A Simulation Model for Two-Lane Urban Work Zones

摘要

Unnecessary operations on ill-designed work zone would cause heavy monetary losses and also put users at tremendous inconvenience. Therefore proper design of work zones to accommodate traffic is very important. Previous studies have concentrated on the optimization of work zone length by minimizing the total cost comprising of user and construction cost. This study extends the existing literature by proposing a discrete stochastic event simulation model, which considers the randomness associated with the arrival process. Simulation is done for a variety of different cases and the results are tabulated after performing output analysis to determine the confidence intervals for the various performance measures.
