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
Soil Bearing Capacity Calculator
Estimate the ultimate bearing capacity of soil beneath a square footing using Terzaghi's general bearing-capacity equation. Foundational geotechnical design input — used with appropriate safety factors to determine maximum allowable footing loads.
