Freeway Traffic Volume Prediction Based on Improved Cell Transmission Model

Abstract

The traditional cell transmission model (CTM) requires that all cell lengths must be equal. In order to improve the applicability of CTM model and make the prediction result more accurate, improved CTM was proposed. In the improved CTM, the length of the cell cannot be equal, so it is more suitable for the prediction of different length sections on the highway. The simulation results show that the improved CTM model meets the requirements of freeway traffic flow forecasting.
