The contractor may supply the traffic signal equipment.

The state may furnish the traffic signal equipment. With this method, the state purchases the traffic signal equipment through the general warehouse, small purchase, or blanket order and provides the equipment to the contractor for installation. This method will also require that a Public Interest Statement (PIS) be submitted to TRF for approval. The PIS must include justification as to why it is in the public's best interest that TxDOT provide the signal equipment.

When a traffic signal is being installed in a city, the city may supply the traffic signal equipment to the contractor for installation. If the city wishes to be compensated for providing the equipment, a PIS must be submitted to TRF for approval.
