The number of highway work zones is increasing due to the aging highway infrastructure, and the increasing number of work zones demands spatial and temporal coordination of these work zones for efficient use of the existing transportation network. Individually scheduled C/M projects may prevent drivers from using alternative routes due to another work zone. Consecutive construction/maintenance activities along a corridor, mainly due to the lack of coordination, become a source of public complaints. This study is seeking an optimal schedule for multiple construction projects by applying a genetic algorithm to a transportation network problem.
