Traffic Signal Management Platform

Every Signal.
Every Corridor.
Every Second Accounted For.

Signal orchestrates the pulse of a city — every intersection timed, every corridor modeled, every phase calibrated to move 10,000+ vehicles per hour without a single wasted green.

Model every phase, every movement, every conflict point before a single controller is reprogrammed. Signal's intersection engine validates timing plans against MUTCD warrants and capacity thresholds in real time — not after a field study.

Corridor-Level Timing Plans

Living Blueprints.
Not Static PDFs.

Signal renders every arterial corridor as a dynamic timing plan — green pulses flowing through each intersection in sequence, offset calculations updated live as demand shifts, compliance flags raised automatically against federal standards.

From the Field

Engineers Who've
Stood at the Glass.

"Signal's corridor model flagged a queue spillback issue on our 14th Street arterial that we'd been chasing for two years. The phase adjustment took 20 minutes. The spillback disappeared in the first PM peak."
