Research Report Agreement T2695 Task 61 Single Loop Video DataResearch Report Agreement • January 22nd, 2007
The speed estimation parameter, g is often regarded as a constant that converts the occupancy into density, and the space mean speed is then calculated by the fundamental relationship between volume, density, and space mean speed. Because both traffic volume and lane occupancy are direct measurements from single loops, and T is a known variable from the system configuration, assuming a constant value of g for speed estimation with Equation (2-1) is simple and has been employed by many state departments of transportation. The Chicago Traffic Systems Center uses g = 1.90 (Aredonk, 1996), and WSDOT used g = 2.4 for a number of years until recently.
