Speeds

An alternative definition that appears in the literature for the space mean speed is based on the average time taken to cross a given distance, or space, X:

Equations 7 & 8

Graphic image of a mathematical equation explaining ti is the time for the l to the th vehicle to travel the distance X: ti= X/vi.  The space mean speed can be calculated as the harmonic mean of the individual vehicle speeds as follows: bar over vs=1/1/N Σ over i 1/vi
