National Traffic Signal Report Card
• Overall score is low
• Management & detection scored lowest• Individual intersections scored highest• Large systems scored higher than
national
National Traffic Signal Report Card:
Why such a low score?Signals turn green, yellow and redBUT,Not operating as an efficient, well-
integrated systemProactive management is limitedLimited resources spent fighting fires
National Traffic Signal Report Card:Other Findings
Proactive Management68% have no documented management
plan or manage “ad hoc”
Coordinated Operations50%+ do not conduct timing reviews every
3-5 years
National Traffic Signal Report Card:Other Findings
Individualized Operations75% have no documented process to
trigger timing reviews
Detectors1/3 have no regular process for collecting
data for timing
MaintenanceAgencies operate with minimum staffing
National Traffic Signal Report Card:What We Learned
Nation doesn’t support signal operations wellResource limitations result in inefficient operationsAgencies manage signals by fighting firesSmall investments have big benefits (40:1 B/C)We can do better!
National Traffic Signal Report Card:More Resources Needed
Signal Hardware - $265m/yearTiming Updates - $200m/yearMaintenance - $500m/yearTotal - $965m/year
$104B/year spent on highway transportation

If we had the resources for a high score
Delay would decrease by 15-20%Travel time would reduce up to 25%Emissions would reduce up to 22%Fuel consumption would reduce up to
10%
