- Abstract:
-
To overcome shortcomings of pre-timed Public Transit Priority (PTP) co ntrol algorithms which are not sensitive to live traffic flow fluctuations, a no vel fuzzy logic controller is proposed. This control algorithm, using the degree of bus delay and queuing of cars as input variables, and green signal delay of current phase as an output variable, gives improved control with the target of m inimizing total delay for passengers. Simulation results with Matlab6.5 software show that the fuzzy logic algorithm is more effective than a pre-timed control, with the average delay per person under fuzzy control 26.6% lower than under pr etimed control.
