| Abstract | Transportation networks serve as critical hubs in city operations, facilitating the movement of people and goods. However, transportation networks are inherently susceptible to random events like weather or accident, which causes nodes or links within the network to deteriorate at varying degrees, ultimately resulting in degradable capacities. Capacity degradation due to deteriorated roads could increase congestion, and thus significantly influence travel time reliability and carbon emission. This study employs the Dirichlet distribution to model stochastic capacity degradation and introduces Monte Carlo simulation to simultaneously assess both travel time reliability and carbon emission. A numerical example indicates that as network degradation intensifies, travel time reliability (TTR) declines while carbon emissions increase, yet they exhibit distinct evolutionary patterns.
