What is with the Traffic Plugin options?
The May 2010 NAM marks the advent of the new NAM Unified Traffic Simulator, which comes in five different capacity levels (Classic, Low, Medium, High and Ultra in order of lowest to highest). Additionally, the NAM Simulator can be customized using the new Traffic Simulator Configuration Tool (TSCT). The old traffic simulator options from the July 2009 release and earlier are available in the NAM Previous Traffic Simulators package. Please note that these options are not supported.
