This research presented a bi-level programming approach to optimize the schedule of urban road construction activities based on a hypothetical transport network,with an objective of minimizing the overall traffic delays.A heuristic algorithm was utilized to identify a set of road construction schedules,while PARAMICS was adopted to estimate the total travel time in the network under each road construction scenario.To test the performance of proposed heuristics-simulation methodology,a numerical test was implemented.The overall results suggested that the proposed methodology could quickly find the optimurn solution with good convergence.
