Applicability of SIDRA for heterogeneous traffic

Delay is an important factor in the optimization of traffic signals and the determination of the level of service of a signalized intersection. Various models have been developed to estimate delay to traffic at signalized intersections. All the models are based on homogeneous traffic conditions; the...
