Study of Intersection Control Mode Evaluation Based on Environmental Effect

Transportation costs,energy costs and environmental costs were used as indicators for the development of comprehensive index evaluation model.Paramics and CMEM model were used as the basic tools for simulating the scenarios of different flow levels.Yield-regulated control mode,roundabout mode and signal control mode were simulated in each condition and evaluated respectively.The results show that the proportion of energy cost is the highest in the total economic cost,and the economic cost of yield-regulated control mode in low flow level is the lowest while the total cost of signal control mode is lower than the others in middle or high flow levels.
