Abstract: We study the constraint on deceleration parameter q from the recent SNeIa Gold dataset and observational Hubble data by using a model-independent deceleration parameter q(z) = 1/2 - a/(1 + z)(b) under the live-dimensional bounce cosmological model. For the cases of SNeIa Gold dataset, Hubble data, and their combination, the present results show that the constraints on transition redshift z(T) are 0.35(-0.07)(+0.14), 068(-0.58)(+1.47), and 0.55(-0.09)(+0.18) with 1 sigma errors, respectively.
