Q1 · Level 1 · TE-TRF-0002
The fundamental relationship between speed (u), density (k), and flow (q) in traffic stream theory is:
Q2 · Level 2 · TE-TRF-0001
Webster's formula for optimum signal cycle length is C₀ = (1.5L + 5)/(1 − Y), where L is the total lost time per cycle and Y is the sum of critical flow ratios. The term 'L' represents:
Q3 · Level 4 · TE-TRF-0004
A 3-phase signal intersection has critical flow ratios: y₁ = 0.30, y₂ = 0.25, y₃ = 0.20, with 4 seconds lost time per phase. Using Webster's method, determine the optimum cycle length and the effective green time for each phase.
Q4 · Level 5 · TE-TRF-0005
An intersection has 2 phases. Phase 1 (N-S): demand = 900 PCU/hr, saturation flow = 3600 PCU/hr. Phase 2 (E-W): demand = 720 PCU/hr, saturation flow = 3000 PCU/hr. Lost time = 4 s/phase. Using Webster's method, calculate the optimum cycle length and check the degree of saturation for each phase. Is the intersection operating within capacity?
