“…They use the combined model to evaluate the performance of various variable message sign strategies on a hypothetical 14-link network. Lin et al (2011) couple a mesoscopic traffic simulator (DynusT; Chiu et al, 2011) with the microscopic emissions model MOVES in order to evaluate the impact on CO 2 emissions of various congestion management schemes in Sacramento (California, USA). Lee et al (2009) use a microscopic traffic simulator (TransModeler;Caliper, 2008) in combination with both a microscopic emissions model (CMEM; Scora et al, 2006), which is used to estimate CO, CO 2 , HC and NO x , and a macroscopic emissions model (EMFAC; CARB, 2008), which is used to estimate PM.…”
