We assume that individuals in population i {1: novice drivers, 2: skilled drivers} have strategy j {1: expressway, 2: ordinary highway route} to choose from. Here, we only consider the evolution in an infinite and well-mixed group, which includes both novice and skilled drivers. The variable x denotes the proportion of novice drivers, and the proportion of skilled drivers is . denotes the proportion of group i choosing strategy j. The ratio of strategy choice is for the novice drivers and for skilled drivers. The most significant difference between the two routes is travel speed. We assume both routes meet capacity requirements without congestion or speed fade. Without loss of generality, the parameters of average speed of the expressway are set to be and the ordinary highway .
