Abstract

Some observations are made on the fundamental diagram of freeway traffic,among which are three influence regions, three types of transition around capacity, and a capacity drop phenomenon. This research aspires to interpret these observations from the human factors perspective in traffic flow theory. A combination of these factors shapes the above-mentioned influence regions, transition around capacity, and capacity drop. Of critical importance in determining the transition around capacity and capacity drop is drivers' aggressiveness, a factor that has long been overlooked in the past. This paper provides a detailed account of where it comes from and how it influences the fundamental diagram.
