intersections unsafe for vehicles and pedestrians
Intersections are a major source of crashes and vehicle delay (as vehicles yield to avoid conflicts with other vehicles).

Why Traffic Signals?
Most roadway intersections are not signalized due to low traffic volumes and adequate sight distances.
At some point, traffic volumes and crash frequency is very high so we have to install traffic signals.
