Abstract
The prediction of the incident duration is an important issue to the advanced traffic incident management. An accurate prediction of incident duration contributes significantly to making appropriate decisions to address incidents for traffic managers and obtaining traffic information for travelers in a timely manner. This paper analyzes several regression methods, such as the principal component regression (PCR), partial least square regression (PLSR), and builds models between incident duration and its influence factors. The models were established for three types of incident, correspondingly, i.e. stopped vehicle, lost load, and accident. The models received the best prediction accuracy of 83.6%, 92.7%, and 88.2% for stopped vehicle, lost-load and accident at error for 20 minutes, respectively. The results indicated that the regression method is a promising application to predict incident duration and the PCR and the PLSR have a better performance.
