In order to understand the safety characteristics of continuous downgrade segment in two-lane highway, some investigations and analyses were done. The data we collected included accident data, geometric data, driveway data, roadside data of G110 highway in Beijing. Road accident data collected was from 2002 to 2004. This paper illustrated the spatial patterns of geometric and accident data using distributing analysis and road accident hotspots identification. The Poisson modeling technique was also used to deliver the compositive relation of the traffic accident occurrence, traffic composing and driveway density in continuous downgrade segment. The estimation results can enhance our understanding of the road character of accident hotspots, the effect of reverse grade, and the compositive character in continuous downgrade segment in two-lane highway.
