Resilience Analysis of Urban Road Networks Based on Adaptive Signal Controls: Day-to-Day Traffic Dynamics with Deep Reinforcement Learning

Figure 6

Evolution of route costs, route flow, and total cost evolution under different levels of disruptions when the ASC based on DRL is employed. First row (from (a) to (c)): the evolution of route costs, route flow, and total cost when the capacity of link 9 reduces by 25%; second row (from (d) to (f)): the evolution of route costs, route flow, and total cost when the capacity of link 9 reduces by 50%; third row (from (g) to (i)): the evolution of route costs, route flow, and total cost when the capacity of link 9 reduces by 75%.
