$4\mathrm{.}31$ A transit route with vehicles operating in mixed traffic has a total of $10$ bus stops. Based upon ridership observations, it was determined that bus stop $7$ is the critical bus stop. This is an on$-$line stop, located at the far side of a signalized intersection. The following information is provided:

Dwell time at bus stop $7=35$ seconds;

Curb lane volume $=600p\frac{c}{h}r$;

Capacity of right curb lane $=800p\frac{c}{h}r$;

The signal has a cycle length of $80$ secs$,$ and the bus approach gets the green for $50$ secs;

Bus stop $7$ has $2$ loading areas.

Determine the bus lane capacity, given that it is desired to limit the probability of a queue forming behind the bus to less than $10\%.$
