| Abstract: | The object is to develop a simulation-based dynamic traffic assignment model to analyze the impact of various emergency situations and response countermeasures.The analysis was conducted from three perspectives:network,route,and link levels.The effectiveness of route guidance system(RGS) was also assessed.Simulation results reveal that incident duration is the most significant factor for network performance.For traffic crashes,clearance time and quick response are highly recommended.Lane closure has a relat... |
