  In this paper, we investigate a scalar field Brans-Dicke cosmological model
in Lyra's geometry which is based on the modifications in geometrical term as
well as energy term of Einstein's field equations. We have examined the
validity of proposed cosmological model on observational scale by performing
statistical analysis from latest $H(z)$ and SN Ia observational data. We find
that the estimated values of Hubble's constant and matter energy density
parameter are in agreement with their corresponding values, obtained from
recent observations of WMAP and Plank collaboration. We also derived
deceleration parameter, age of the universe and jerk parameter in terms of
red-shift and computed its present values. The dynamics of deceleration
parameter in derived model of the universe shows a signature flipping from
positive to negative value and also indicates that the present universe is in
accelerating phase.
