Town of Mendon , VT US Route 4 Mendon Village Solar Powered Radar Speed Limit Signs Project The Town of Mendon seeks to have a radar speed limit feedback sign installed on US Route 4 located on the East and West ends of the Village of Mendon , Vermont . These signs will be installed with a solar battery to power it . The intention is to create a safer community by giving drivers a visual cue to reduce their speed on the road . Before installing the Driver Feedback Sign , an installation site must be selected . It is very important to select a site with the following characteristics : Pre - Install There must be a clear view of the sign from the roadway for at least 500 feet , and the viewing area must be clear of trees . Attenuation of the radar ’ s signal , caused by trees , may reduce the radar ’ s effective range . Do not install the sign facing an intersection or bridge if possible . If the sign must be installed facing an intersection or bridge , the sign should be located at least 400 feet away . Cross - traffic may be registered by the radar as an oncoming vehicle . The sign should be located at least 200 feet away from large street signs that fall within the radar ’ s detection zone and cause the radar to reflect its ’ output . Reflecting the radar ’ s output by objects such as signs may cause vehicles to be detected in the opposite direction . Install sign in roadway geometries that allow clear view of the sign ’ s display and provide the most efficient radar detection zone . Proper site selection will provide the greatest traffic calming effect and sign performance . Using Class B concrete ( 3000psi ), the concrete footing will be installed to a depth of 4 ’ ( FOUR FEET ) and width of 2 ’ ( TWO FEET ). The are 4 anchor bolts that are secured in the footing along with a flexible conduit to run a # 6 grounding wire to a ground rod . The ground wire will be attached to the ground rod using an exothermic weld . There will be 4 # 6 Bars 5 ” shorter than the footing height .
