“…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.…”
