Abstract: Through analysis of the relationship between economic growth along freeway and variety of traffic volume, the assumption that the ratio of the price and volume were steady is proposed, and the induced traffic volume of economic forecasting model is established. Then the parameter of the induced traffic volume of economic forecasting model and relevant function models are provided, and the method and step of the induced traffic volume predicting are discussed. Finally, a real instance is adopted to validate the method.

Key words: freeway, induced traffic volume, induced economic growth, ratio of the price and volume, economic forecasting model
