A simplified procedure is proposed for the design of end-plates and base-plates of cantilevered traffic sign, signal, and light structures, and also for base-plates of span-wire-mounted traffic-signal structures. This procedure is based on beam and plate bending and torsion theories, and is intended for routine application by practicing engineers designing these items. Results obtained using the proposed procedure compared well with those estimated using finite-element analysis and full-scale testing.
