Given a 4-regular graph F, we introduce a binary matroid M (F) on the set of transitions of F. Parametrized versions of the Tutte polynomial of M(F) yield several well-known graph and knot polynomials, including the Martin polynomial, the homflypt polynomial, the Kauffman polynomial and the Bollobas-Riordan polynomial.
