AbstractBased on GIS and the basic model of hot zone, the identification method of road hot zone was studied. Road networks were merged by following a priority sequence, and the basic spatial units(BSU) of road were obtained. The spatial distribution of traffic accidents was simulated, and the threshold value of traffic accident for each BSU was defined by using Monte Carlo method. The spatial contiguities of BSUs were examined to obtain hot zones, and the hot zones around Shanghai Expo Venue were identified. Analysis result shows that the share of irregular BSUs decreases from 41.5% to 14.8% after merging road networks. There are 84 hot zones involving only vehicles and 33 hot zones involving pedestrians, which accords with the real situation. So the method can effectively identify road hazardous locations. 5 tabs, 6 figs, 14 refs.
