Kinematical models are constrained by the latest observational data fromgeometry-distance measurements, which include 557 type Ia supernovae (SNIa)Union2 data and 15 observational Hubble data. Considering two parameterizeddeceleration parameter, the values of current deceleration parameter $q_{0}$,jerk parameter $j_{0}$ and transition redshift $z_{T}$, are obtained.Furthermore, we show the departures for two parameterized kinematical modelsfrom $\Lambda$CDM model according to the evolutions of jerk parameter $j(z)$.Also, it is shown that the constraint on jerk parameter $j(z)$ is weak by thecurrent geometrical observed data.
