Along with the development of the national economy and the improvement of people’s living standards, the development of Commercial plaza has gradually become the most suitable consumption patterns for the modern urban. Development and construction of commercial Plaza is bound to produce and attract large crowds and traffic. And then change the distribution of traffic flow around the square network, and bring huge traffic load to the network of local, even global. Eventually lead to traffic problems, such as traffic congestion, traffic accidents, environmental degradation, etc. Traffic impact analysis is to analyze and evaluate the impact of construction projects on the surrounding road network traffic load, from microscopic study on relationship between urban land use and urban transport, solve urban traffic problems effectively.On the basis of analysis and summing up of foreign-related experience, combined with china’s current situation of the traffic impact assessment, this paper introduces traffic impact assessment system of commercial Plaza systematically, analyzes the steps and method of traffic impact assessment and technology involved in the traffic impact assessment process in detail. Then this paper gives the method to determine the target year and peak time. This paper also gives the method to determine threhold for traffic impact assessment. Besides, on the basis of Investigation on status of traffic flow, the traffic demand is divided into background traffic volume and project traffic volume to be forecast respectively. This study aslo uses the four-stage method to forecast the traffic volume.At last, the paper uses a Shopping Plaza as example for traffic impact assessment to explaine work processes, approaches, methods and solutions of the traffic impact evaluation, and verify the rationality and practicality of paper’s methods and theories. In the view of the development in China, city center area still needs to build a large number of commercial Plaza in the future for a long period of time. Given of the traffic demand characteristics of the commercial projects in the city center area, this paper proposes traffic evaluation methods applicable to it development characteristics, it can coordinate land development and transportation services, and clear traffic responsibilities of developer. Traffic impact assessment has important significance to alleviate the urban transport crisis and promote healthy and sustainable development of the city.
