Context A data set of historical toll prices on Mopac express lanes in Austin, Texas. Variable tolls are used to manage the number of vehicles entering the express lanes at any given time. When traffic is heavy and demand for the Express Lanes is high, toll rates increase. When demand is low, toll rates go down. The prices are indicative of traffic on these express ways. The express lanes have multiple segments and run in two directions - north bound and south bound.
