With the rapid economic and social development in Jinan City, the average growth rate of motor vehicle ownership and driving the number maintained in more than 15 percent of the people of the city traffic, vehicles, roads have become increasingly prominent, seriously affecting urban life and economic development in . If you can not be effectively addressed and governance, is bound to pose a serious threat to the sustained, rapid and healthy development of Jinan City economy. In this paper to learn about the investigation and gathering Dikou road, road and traffic data (including basic road conditions, the peak traffic flow parameter data, traffic congestion causes) 更多：https://www.bmcx.com/ , to analyze the congestion causes. After careful study, the paper argues thatShould be the focus of the governance Dikou road traffic congestion from the perspective of road planning and construction and traffic control, combined with intelligent transportation system to carry out comprehensive improvement; sections of the main intersection, traffic flow theory, reveals the point of conflict exists endanger the source of traffic safety, traffic flow control and reduce the point of conflict is to improve the intersection capacity key. Mentioned in the text at the end of the article, a simulation study to combine vissim emulation software on the main Jinan City Dikou Road two intersection, through the simulation comparison analysis of before and after optimization,Come to the conclusion that the new program could improve the efficiency of the intersection traffic.

With the rapid economic and social development of Jinan, the number of cars and driving more than average growth rate for the number of 15%, city traffic, vehicles, roads become apparent contradictions, seriously affecting the lives and the economic development of the city. If it cannot be effectively solved and governance, Jinan City, is bound to the sustained, rapid, and healthy economic development posed a serious threat. Through this article to understand, investigate and acquisition of dikoulu road and traffic data (including basic road conditions, causes traffic jam in peak traffic flow data 更多：https://www.bmcx.com/ , and so on), analysing its causes jams. After careful research, think of this article,Governance dikoulu traffic hold blocking of focus should from road planning and construction and traffic tube control of angle, and auxiliary to intelligent traffic system to for integrated treatment; in sections of main cross mouth, to traffic flow theory for Foundation, reveals has conflict points exists is endanger traffic security of roots, effective to for traffic flow control and reduced conflict points is improve cross mouth passage ability of key is located. At the end of the article, the combination of methods in simulation software vissim of Jinan City dikoulu a simulation study of two major intersections, before and after optimization by simulation comparison analyses,Draw conclusions of new programmes to improve the efficiency of traffic at intersections.

With the rapid development of economy and society in jinan city, motor vehicle quantities and driving number of average growth rate to stay above 15%, the city traffic people, cars, and contradiction between, severely affects city life and economic construction and development. If can't effectively solve and management,Will the economy in jinan sustained, rapid and healthy development of a serious threat. based on the field investigation and collection dike know, mouth road and traffic data (including basic road conditions, rush hour traffic flow parameters data 更多：https://www.bmcx.com/ , traffic jams the causes), analysis of the causes of traffic congestion. After careful study,This paper thinks, mouth road traffic congestion management dike the key should be from a road plan and construction and traffic control point of view, and with the intelligent transportation systems to comprehensive rearrangement; In a section of the main intersection to traffic flow theory as a foundation, reveals the existing ChongTuDian is to endanger the root of traffic safety,Efficient traffic flow control and reduce ChongTuDian is to improve the traffic capacity of intersection point. at the end of the article, using the proposed method and combining with the vissim simulation software in jinan mouth road embankment two major intersection simulation research, through the optimization of the simulation analysis before and after,By using the new scheme that can improve the efficiency of the intersection traffic conclusion.
