“…More recently, a number of approaches have been proposed employing various computationally expensive numerical solution algorithms, including genetic algorithms (AbuLebdeh and Benekohal, 1997;Lo et al, 2001), multi-extended linear complementary programming (Schutter and Moor, 1998), and mixed-integer linear programming (Lo, 1999;Beard and Ziliaskopoulos, 2006). In Lo (1999); Lo et al (2001); Beard and Ziliaskopoulos (2006) the traffic flow conditions are modeled using the cell transmission model (Daganzo, 1994), a convergent numerical approximation to the first-order hydrodynamic model of traffic flow for network links.…”

“…In Lo (1999); Lo et al (2001); Beard and Ziliaskopoulos (2006) the traffic flow conditions are modeled using the cell transmission model (Daganzo, 1994), a convergent numerical approximation to the first-order hydrodynamic model of traffic flow for network links. In view of the high computational requirements, the reallife implementation of these optimization-based approaches might face some difficulties in terms of real-time feasibility.…”

“…A los efectos de aliviar la carga computacional se han diseñado simplificaciones del modelo LWR tales como el método CTM (Cell Transmission Model) desarrollado por Daganzo (1994Daganzo ( , 1995, que es una aproximación de diferencias finitas al LWR que permite obtener resultados similares a aquel con menor tiempo de cálculo. Lo et al (2001) han desarrollado una formulación de control de semáforos (DISCO) basada en la combinación del modelo CTM con el método de optimización de Algoritmos Genéticos. La metodología DISCO ha mostrado ser eficiente en diversos escenarios brindando resultados comparables y aún mejores que el código comercial TRANSYT (Courage y Wallace, 1991).…”

“…As an extension to the LWR model, Daganzo (Daganzo, 1994) built a cell transmission model (CTM) to evaluate the traffic on a highway network with a single entrance and exit. Some improvements of CTM are further explained in literature (Lo, 1999;Lo et al, 2001;Daganzo, 1995). However, CTM is only sufficient for signalised networks where the traffic interaction among flows from competing arms is eliminated.…”
