Abstract:With the expansion of Zibo city urban space, the level of urban residents motorization continues to improve, the city scale is expanding year by year, followed by the rapid growth of the total amount of urban traffic. There are no skeleton expressways in the main urban area and between groups, and the urban traffic is dominated by trunk roads. The main highways are connected between the groups, and the interference of transit traffic and freight traffic is becoming more and more serious. The congestion of the backbone communication channels between the groups is significant during peak hours. In order to support industrial layout and urban development, and improve the operation efficiency of urban road traffic network in Zibo, it is necessary to build a fast passage network with clear function, reasonable structure, high efficiency and smoothness, which is suitable for urban development, integration of support groups and traffic demand.
