摘要：	A comprehensive highway capacity study and guideline development was undertaken in the Hebei and Henan provinces in 1995-1999. Field data collection was conducted at 144 road links and at 19 major intersections outside of urban areas. Aggregated data from all road link sites were analyzed to obtain passenger car equivalents, free-flow speed, and speed-flow-density relationships for all road and terrain types. Significant influencing factors included cross section characteristics, road class, side friction, and terrain type. The intersection analysis showed that traffic flow, split between major and minor road traffic, level of side friction, and road width were the main variables influencing traffic performance. Driver behavior studies showed that only 40% of the vehicles waited for a gap in the major road flow making it impossible to use gap acceptance models. A further development of the capacity guidelines based on data from five more major provinces in China is under way led by the Highway Research Institute, Beijing.
