Civil
Traffic Signal Timing Calculator
Determine the optimal signal cycle length and green time splits for a two-phase intersection. Used by traffic engineers when designing or re-timing signals to minimize delay and prevent overflow queuing.

Civil
Retaining Wall Design Calculator
Calculate active, passive, or at-rest lateral earth pressure on a retaining wall given soil properties, wall height, and surcharge loading. Use it when designing gravity walls, cantilever walls, or checking overturning stability.
