Traffic management techniques (beyond the MUTCD) used to reduce delay in work zones

Puerto Rico has used different techniques.
a) In urban areas traffic signals have been reprogrammed using historic and actual data on the area of the project.
b) In some cases reversible lanes are prepared while areas are in construction to handle high peak volumes in the mornings and afternoons.
c) The work near or at intersections is done during the night and on weekends. The Authority holds special meetings to establish a total commitment and coordination for this work.
d) Portable variable message signs are used for some projects.
