Traffic organization during urban road constructions

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 optimum solution with good convergence.
