Fargo has about 180 signalized intersections; engineers explain how signals are timed
Summary
City Engineer Tom Nachmus said Fargo operates roughly 180 signalized intersections and uses software plus spacing and posted speed limits to coordinate green lights on corridors; alternatives such as roundabouts and reduced-conflict U-turns are used when warrants are not met.
City Engineer Tom Nachmus said Fargo manages a large signal network and uses software tools and spacing strategies to time signals so drivers who follow the posted speed limit are more likely to encounter green lights along corridors. “I think we have like 180 signalized intersections in the city,” Nachmus said, noting the work needed to maintain and coordinate signal systems.
Nachmus said engineers evaluate signal placement against Federal Highway guidance and a set of warrants—traffic volumes, pedestrian counts and turning movements—to decide whether a signal is the right solution. He noted the city sometimes chooses alternatives such as reduced-conflict U-turns and roundabouts, citing an installation on 52nd Avenue west of 45th Street as an example.
