Traffic Flow Rate (q) vs Vehicle Density (k)

Formula

## 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.

Esempio Risolto

30 vehicles per km travelling at 60 km/h.

  1. 01q = 30 x 60 = 1800 vehicles/hour
  2. 02Headway = 3600 / 1800 = 2.0 seconds
  3. 03Spacing = 1000 / 30 = 33.3 m between vehicles
