## Fundamental Traffic Flow Equation
Traffic flow, density, and speed are linked by a fundamental relationship.
### Formula
**q = k u**
where q is flow rate (vehicles/hour), k is density (vehicles/km), and u is space mean speed (km/h).
Time headway = 3600/q seconds. Spacing = 1000/k metres. At capacity, flow is maximised with moderate speed and density.

Ejemplo Resuelto
30 vehicles per km travelling at 60 km/h.
- q = 30 x 60 = 1800 vehicles/hour
- Headway = 3600 / 1800 = 2.0 seconds
- Spacing = 1000 / 30 = 33.3 m between vehicles
