The proposed E-470 beltway is a 48-mile circumferential highway which will connect major public and private developments east of the Denver metropolitan area as well as the new Denver International Airport to the Denver, Colorado metropolitan area. The E-470 forecasting model was developed using MINUTP software on a micro computer. A focused model approach was used to incorporate regional traffic impacts in the beltway corridor. To more accurately predict toll revenue, the concept of developing a model which could simulate a driver's decision whether or not to use the tollway was implemented. The model was conceived in such a way as to be sensitive to a variety of statistically significant variables. In this way, the model has been capable oftesting the impact of both physical and policy considerations.
