摘要：AbstractThe article has studied about the temporal distribution characteristics of freight transportation in common condition. The research applied SQL database to streamline and screen GPS data in programming language. The research used Matlab to check the validation and smoothness of the data, and it used Excel to analyze the time characteristics of the freight traffic in Shenzhen City and then utilized traffic wave theory model to have quantitative calculation to get its impact. It portrayed the traffic delay generated by the superposition of passenger traffic and freight traffic in the passenger commuter rush-hour stage. With the analogy on the analysis of existing data, the study extracted the running characteristics from the freight traffic phenomenon based on the macroscopic traffic demand of freight transportation, temporal and spatial characteristics of the freight transportation in Shenzhen City. Besides, by the methods of the appropriate allocation of resources, the research results have a positive and important role in social production and traffic conditions. It may promote the development of the modern city and enhance the overall effectiveness of transportation as well. The study results want to achieve an enhancing positive and important impact on the core competitiveness of Shenzhen City in the context of globalization.
