The system includes a sensor associated with at least one of the streetlights and configured to detect the presence of a moving vehicle and to provide a signal representative of the moving vehicle. The system further includes a radio frequency transceiver associated with each of the streetlights. The system yet further includes processing electronics configured to receive the signal representative of the moving vehicle from the sensor and to cause the radio frequency transceiver to transmit a command to one or more of the plurality of the streetlights to change lighting states along a pathway for the vehicle. ## Claims ### Claim at position 1 1-12.
