摘要：AbstractThe diamond interchange is one of the common forms of road intersection. The design of most of the existing diamond interchanges is based on unsaturated traffic conditions, and transit operation shows its unique properties when traffic tends to reach saturation. In view of this, we analyzed the traffic organization of diamond interchange, studied the improvement of scheme and focused on the import and export of massive diamond interchange traffic organization. VISSIM software was used to simulate the adjustment effect of import and export of the massive in saturated traffic conditions with the specific parameters such as average delay time, average queue length and the times of the average parking. Import and export traffic organization before and after adjustment was also evaluated based on entropy of the congestion of intersection to make objectively assessment more effective.
