A detailed phenomenological model is developed for the normal state transport properties of optimal and overdoped high-Tc cuprates. In particular, an explicit form of scattering rate is identified that may account, qualitatively and quantitatively, for the normal state (magneto)-transport properties of Tl2Ba2CuO and Bi2Sr2CaCu2O across the overdoped side of the phase diagram. The proscribed form of the scattering rate is consistent also with features seen in the photoemission spectroscopy of Bi2Sr2CaCu2O and offers a new and intuitive way to understand the evolution of the temperature dependence of the inverse Hall angle in Bi-based cuprates with carrier concentration.
