Answer: D
The method not used for speed and delay studies is the Pavement Unevenness Method.
Speed and delay studies measure journey times, running speeds and the location and causes of delays along a route. The usual methods are the floating car (moving observer) method, the license plate method, photographic techniques, elevated observers and interviews.
Pavement unevenness is measured with instruments such as the bump integrator to assess riding quality of the road surface. It is a pavement evaluation test, not a traffic study, so it is the odd one out.
