Method of Expressway Traffic Volume Forecast Based on Searching Traffic Volume Evolvement Mode

The effect of an accident occurring on an expressway can be estimated by the method of traffic volume forecasting. The common characteristic of forecast algorithms is that they need historical data support, and an algorithm always forecasts more accurately by absorbing additional data. Referring to the theory of image compression, the historical traffic volume evolvement mode was abstracted from history data and the evolvement mode was expressed by compressed code. Historical data similar to current traffic volume evolving can be selected by searching similar compressed code and traffic volume trends can be forecasted by integrating this historical data which has similar evolvement mode. Factual experiment shows that the forecasted data has good coherence with real data.
