1. A traffic mitigation device, the device comprising:
a base having a base sidewall including first threads;
a cap movably coupled to the base, the cap having a cap sidewall including second threads and at least one rib;
a motor operable to move the cap between a flush position and a raised position by rotating the cap along the first threads engaged by the second threads;
a pinion coupled to the motor;
a rotator rotatably positioned in the base, the rotator including a ring gear positioned to engage the pinion and at least one slot positioned to engage the at least one rib;
a battery electrically coupled to the motor;
a power generator electrically coupled to the battery, wherein the power generator is configured to generate electricity and charge the battery with the generated electricity; and
an electronics unit housed in the base or the cap, wherein the electronics unit comprises:
a control circuit configured to control operation of the motor; and
a communication module operably coupled to the control circuit, wherein the communication module is configured to receive one or more signals from communication modules of adjacent traffic mitigation devices,
wherein operation of the motor rotates the pinion along a motor axis,
wherein rotating the pinion rotates the ring gear and thereby the rotator and the at least one slot about a vertical axis,
wherein rotating the at least one slot rotates the at least one rib and thereby the cap about the vertical axis,
wherein rotating the cap causes the second threads to engage the first threads and thereby move the cap between the flush position and the raised position, and
wherein the control circuit is configured to operate the motor such that the cap moves between the flush position and the raised position synchronously with caps of the adjacent traffic mitigation devices based on the one or more signals.
