https://doi.org/10.1057/9781137297723sportation economists (and other transportation researchers) have used two models of traffic that are considered to be alternative approaches to the study of urban highways; the continuous (steady-state) flow model and the bottleneck model. These two models are discussed briefly below. The point of
