The invention relates to a rapid road congestion index estimation and prediction method which comprises the following steps: mounting a detection device on a selected road section, and acquiring traffic flow data in real time according to set time periods; according to the acquired traffic flow data, establishing a congestion index estimation model, and calculating the congestion index of a corresponding time node; fitting corresponding congestion indexes of different time nodes within the set time period, establishing a congestion index prediction model of the selected road section, and performing congestion state prediction. By adopting the rapid road congestion index estimation and prediction method, a practical expanding application for roads is achieved through obtained traffic index, a better guiding effect on daily vehicle trips is realized, and a basis is provided for future city traffic management.
