Application and validation of the LWR-IM traffic model in class II urban arterial

This paper presents investigation on the applicability and validity of the Lighthill-Witham-Richards - Integrated Model (LWR-IM) traffic model in modelling and simulating platoon progression and performance indices of traffics in urban arterials. For this purpose, the LWR-IM is applied to a class II urban arterial in the city of Klang, Malaysia. Real traffic demands are fed into the model to simulate the queuing conditions along the arterial. Simulated queues are compared with real queues observed using the two-sampled t-test and the mean absolute error (MAE). The comparison reveals low MAEs and insignificant differences of simulated queues with real queues where the p-values produced concluded that the null hypothesis cannot be rejected. Thus, this further proved the applicability and the validity of the LWR-IM.
