Traffic modeling is one means of being able to predict time-varying traffic conditions in an urban roadway network support traveler information systems and traffic management advisories. The development and testing of DYMOD (a dynamic traffic assignment model) was implemented in the Denver metro area to predict observed volumes and speeds during a typical weekday peak period (5am - 10am). On average, predicted flows agreed to within 12% of actual 5-minute volumes on I-25 through lanes at the detector locations. DYMOD was also able to model incident conditions to generate route diversion planning strategies during lane blocking accidents to estimate vehicle hours of delay.
