Macroscopic simulation of traffic flows in complex freeway segments on a personal computer

A personal-computer based, macroscopic freeway simulation model, called KRONOS, is presented. KRONOS employs the simple continuum modeling approach and explicitly models the interrupted road traffic flow behavior such as merging, diverging and weaving. The coupling effects of ramps on the main freeway are considered in determining actual amount of flows entering/exiting freeways. The current version can handle up to a 32 km (20 miles) freeway section with 8 lanes.
