Based on empirical microwave data on the second Ring Road in Beijing, spatial and temporal characteristics of traffic congestion were analyzed. Three specific indexs for the congestion have been analyzed, i.e., congestion duration, time percentage of traffic congestion and key congestion sections. The hazard-based traffic congestion duration model was established through survival method. Temporal-spatial distribution of traffic congestion was studied using non-parametric method. The discrepancies of traffic congestion on different time and different links were considered. Results show that there has a big difference on congestion duration and congestion number between different links. Hazard rate will be less than 10% when congestion lasting more than 20 minutes. Three characteristics of the key congested points are confirmed. The judgment for key congestion sections show that key congestion segments have original affect to other sections.
