Signal-Planning Optimization Model for Bus Priority Signal Intersections Based on Loss Equilibrium

Abstract:

In order to equilibrate the influence of bus priority induction signal control in non-priority phases, signal timing should be optimized in the intersection. Equilibrium methods are proposed for three bus priority strategies: green extension, red truncation and phase insertion. The unsaturated intersection delay is analyzed for a single bus priority request based on linear vehicle flow arrival process, procedures of green loss and loss offset are considered to infer intersection delay formulation. The signal-planning optimal model with total passengers delay minimum and other phase vehicles passing intersection normally for restraint condition is suggested.
