4 (a) An extended freeway segment with largely level terrain has an observed free flow speed of approximately 110 km/h, three lanes per direction, a 0.9 m lateral clearance, and about one interchange per 1.5 km.

It has an observed volume of 3080 veh/hr with corresponding PHF =0.88 and 154 trucks and buses and no recreational vehicles. An all commuter motor composition may be assumed. Estimate the LOS for this set of conditions 10 marks

5 (a) The off-peak traffic flow arriving at random at toll booth facility is 90 V.P.H and the peak flow is 180 V.P.H. The service rate exponentially distributed at the booth is 3.5 per minute. What is the average number of customers in the queue for each flow? 10 marks

(b) An observation on an expressway yielded a count of 200 vehicles in a period of half an hour. Calculate the number of headways in this count:
i) Greater than 4.5 seconds and ii) less than 18 seconds 15 marks
OR

6 (a) Explain the fundamental diagram of traffic flow and derive the linear relationship between speed and concentration. 10 marks

(b) The maximum capacity of a 2-lane carriageway of a four lane dual carriageway is 2000 veh/hour. Due to pipe laying operations the width of two lane carriageway is reduced, restricting the maximum capacity to 1100 veh/hour.
