In the cartesian coordinate system $(xOy)$, the parametric equation of line $l$ is given by $ \begin{cases} x=1- \frac {1}{2}t \\ y= \frac { \sqrt {3}}{2}t\\ \end{cases}(t \text{ is the parameter })$, and in the polar coordinate system with the origin $O$ as the pole and the positive $x$-axis as the polar axis, the equation of circle $C$ is given by $ρ=2 \sqrt {3}\sin θ$.
(I) Write the standard equation of line $l$ and the cartesian equation of circle $C$;
(II) If point $P$ has cartesian coordinates $(1,0)$, and circle $C$ intersects line $l$ at points $A$ and $B$, find the value of $|PA|+|PB|$.
