Study on the diffusion law of per meation grouting in oval fissure;

Study on the Diffusion and Models of Urban Arterial Road Congestion;

This paper adopts Vissim to analyze the feature of recurrent congestion diffusion,which obtains the wave and delay characteristics,and quantifies such correspondent congestion indexes as queue number and queue length between detector stations.
