A new section of Richmond Highway is being designed as a six-lane facility (three in each direction) with a two-way left-turn lane. Traffic data include directional design hourly volume = 3600 veh/h, PHF = 0.94, assumed base free-flow speed = 55 mi/h (88 km/h). Geometric data include: urban setting, rolling terrain, lane width = 11 ft (3.3 m), shoulder widths = 4 ft (1.2 m) (right side) and 1 ft (0.3 m) (left side), and average access point spacing = 12 points per mile on each side.
The lane of a 2-lane one way carriageway is closed for repairs. The maximum mean free speed under conditions of low flow in the 2-lane portion is 65km/hr. Under conditions of low flow, observations show that the maximum mean free speed in the bottleneck is also 65km/hr. The average space headway when vehicles are stationary is 12.5m. The volume of traffic on the 2-lane road is 1800 veh/hr. Assuming that the speed-concentration relation is linear, find The mean speed of traffic through the bottleneck caused by the closure of one lane; The mean speed of traffic in the congested conditions immediately on the approach to the bottleneck The mean speed of traffic on the carriageway clear of the influence of the bottleneck The rate at which the queue of the congested traffic enter
