From the Rhode Island DOT:
"...Since the pavement must be saw-cut to install the detector, once the wiring for the detector is installed, there is a rubber coating that is placed over the wires to seal the cut in the pavement. This rubber coating is on the surface of the pavement and therefore its location can be seen...
In a few locations throughout the state, the vehicle detectors are embedded in the base of the roadway, which means they are beneath the surface of the pavement and cannot be seen. These types of detectors may be more difficult for motorcyclists to see and therefore cyclists cannot position themselves on the detector to make the light change.
Painting these locations on the roadway cannot be done because doing so would not follow the national standards and guidelines set forth in the Manual on Uniform Traffic Control Devices (MUTCD). This is a publication by the Federal Highway Administration that states nationally accepted standards for all traffic control devices (i.e. signs, pavement markings, traffic signals, etc). All states in the U.S. follow this manual so that there is uniformity in traffic control devices when traveling from state to state.
Our suggestion to motorcyclists at locations where the detectors are embedded is to sit approximately 3 feet off the center of the travel lane. The reasoning behind this is that the standard size for the vehicle detectors is 6 feet by 40 feet, and they are typically placed in the center of the travel lane. Therefore, if riders sit 3 feet to either side off the center of the travel lane, they should be sitting close to the edge of the detector."
