$(5)$

A$)$ A non$-$signalized intersection comprises a one$-$way street carrying $500ve\frac{h}{h}r$ which crosses a two$-$way street carrying $1600ve\frac{h}{h}$ in the same period. There are two traffic lanes on the twoway street and the traffic on it has right$-$of$-$way.

Determine:

The practical absorption capacity of the major stream

The minimum number of lanes required on the one$-$way approach carriageway to eliminate long queuing delays, and hence the average flow per approach lane in the minor road

The average delay to the minor road traffic

The queue length $($with the probability of $95\%$ of not being exceeded$)$
