Both routes I and II use only one-way roads. (a) Travelers simultaneously choose which route to use. Find Nash equilibrium values of m and y, and either provide calculations for your answer or explain your answer. (b) Now a two-way highway is constructed between cities C and D. The C - D highway requires 0 hours of travel time (in either direction) per traveler regardless of the number of travelers who use the road. Find a Nash equilibrium for this new road network. Be sure to specify a; and y and either provide calculations for your answer or explain your answer. (0) Compute the travel time per traveler in the Nash equilibria that you found in parts (a) and (b). You should nd that the time per traveler changed after the new highway was built. Briefly explain why it changed and why it increased or decreased
