“…In this study, we analytically formulate a simplified continuous dynamic network loading problem (Wu et al, 1998;Xu et al, 1999;García-Ródenas et al, 2006) by incorporating an anisotropic flow model (Dell'Orco, 2006;Celikoglu and Dell'Orco, 2007;Celikoglu et al, 2009). We seek the solution within simulation approach by feeding traffic data obtained on a freeway route that is artificially segmented to multiple links.…”

“…This entails to collect huge real-time data which is often a difficult and costly undertaking (Long et al, 2011;Xu et al, 2004). At the present moment, the state of the art of dynamic models is not yet completed and requires improvements related to domains, tractability and realism (García-Ródenas et al, 2006;Lin et al, 2004;Peeta and Ziliaskopoulos, 2001). In fact, the lack of data and resources has sometimes implied model proposals without sufficient revision or proper calibration (Hawas, 2002).…”

This paper presents a methodology for the dynamic estimation of traffic flows on all links of a network from observable field data assuming the first-in-first-out (FIFO) hypothesis. The traffic flow intensities recorded at the exit of the scanned links are propagated to obtain the flow waves on unscanned links. For that, the model calculates the flow-cost functions through information registered with the plate scanning technique. The model also responds to the concern about the parameter quality of flow-cost functions to replicate the real traffic flow behaviour. It includes a new algorithm for the adjustment of the parameter values to link characteristics when its quality is questionable. For that, it is necessary the a priori study of the location of the scanning devices to identify all path flows and to measure travel times in all links. A synthetic network is used to illustrate the proposed method and to prove its usefulness and feasibility.
