Validating the Interval Valued Neutrosophic Soft Set Traffic Signal Control Model Using Delay Simulation.

Currently most signalized intersections in almost all developing countries use fixed time traffic controllers or pre-timed traffic lights. But as a real life situation, in addition to uncertainty and impreciseness there is also indeterminacy in traffic signal control constraints due to various factors like unawareness of the problem, inaccurate and imperfect data and poor forecasting in addition to uncertainty in the constraints. To overcome these interval valued neutrosophic soft set traffic signal control model at four way isolated signalized intersections has been developed. The main aim of this research is to validate the IVNSS traffic signal control model and compare it with fixed time trafic signal control model using MATLAB simulation tool. Vehicle delay at the junction is used as a measure of efiectiveness. The simulation is conducted for seven consecutive days from Monday up to Sunday for eight hours to reflect the difierent trafic flow conditions. The simulated delay model results are analysed under 5 different scenarios. And results showed that in case of heavy trafic conditions vehicle delay under IVNSS trafic signal control model is minimized by 36 percent and under light trafic conditions the average vehicle delay is minimized by 73 percent when compared to fixed time trafic signal control model.
