Determine the saturation flow rate $($in veh$/$h$)$ for a left$-$turn lane that operates in a permitted$-$only mode, under the following conditions.

Opposing demand flow rate $=1,100ve\frac{h}{h}$

Lane width $=10\mathrm{.}5ft$

Heavy vehicles $=2\%$ of the traffic stream

Approach grade $=-4\%$

No on$-$street parking

No bus stops

Bicycle and pedestrian traffic conflicting with this lane group is negligible

Intersection is not in a central business district
