ConnDOT: Acquisition

{Blue Photolog Banner}
ConnDOT's Data Services Section operates two state-owned Automatic Road Analyzer Vans or ARANs to photolog Connecticut's 12,300 state-maintained kilometers annually.

A wheel-mounted distance measuring instrument triggers sensors and cameras to capture at intervals of 4, 5, and 10 meters, depending upon the data item.
