An important aspect to sampling transportation networks that has not been previously examined in detail is addressed here; it incorporates the correlation between road segments in a traffic network into the sampling design. An approach for estimating the correlation between links in a transportation network is described, and a recommended approach for incorporating this correlation into the sampling design is presented. Also, the implementation and evaluation of these approaches relative to simple random sampling without replacement is illustrated by using four sampling scenarios typically encountered when sampling a transportation network.
