Traffic stream characteristics

Fortunately, drivers tend to behave within a reasonably consistent range and, thus, traffic streams tend to have some reasonable consistency and can be roughly represented mathematically to better represent traffic flow, relationships have been established between the three main characteristics: (1) flow, (2) density, and (3) velocity these.
