Q6. Drivers, driving at 60mph, must slow down to negotiate a severe curve coming towards a busy urban interchange. A warning sign for the curve is clearly visible from a distance of 19ft How far in advance of the curve must the sign be located to ensure that drivers can pay attention to the sign, and decide and act accordingly? Use the standard reaction time of 14.5 sec and maneuver time of 4sec Also calculate the final speed (accurate within +2mph) at which the deiver should enter the curve if it is designed for a radius of 89on and superelevation is 4%? Recalculate the radrus for the worst case scenario that drivers do not reduce their speed. Note interpolation for final value of frictional coefficient may be required

A driver will exit from a major road to enter a minor road via a ramp. From a distance of d1, he sees the EXIT sign located at d2 m before the exit RAMP (designed as a circular curve). He has to slow down to enter the RAMP safely while moving over the distance of (d1 + d2) on a 2-percent downgrade. He can read a road sign at a distance of 15 m for each 30 mm of the letter height. He will move along the ramp on a 3% downgrade and come to a complete stop at the STOP sign to enter the minor road as shown in the following figure:
A driver (with a reaction time 0.60 sec) is driving down hill on a 5% grade at 60 km /hr .find minimum stopping sight distance required on highway section ?assume coefficient of friction =0.7 locked wheels?
A traffic stream is moving at a steady state when entering a mountain grade. Upon entering the grade, the speed, density and flow are 72 km/h, 25 veh/km and 1800 veh/hr respectively. On the grade, a truck drops to a speed of 15 km/h causing traffic to bunch up to a density of 85 veh/km. When the truck pulls over, traffic accelerates to the maximum flow until steady state flow conditions resume. Calculate (a) the flow of traffic behind the truck on the mountain grade (b) the jam density and free flow speed for this road (c) the density and speed when traffic resumes a steady state flow (d) the maximum flow
Where you have to put a warning sign for checkpoint if the design speed is 100km/hr, deceleration rate is 3.4m/s² with downgrade 2.5%, and driver reaction time is 0.50 sec?
2 A slight bend prior to a curve means that a 65 km/h curve advisory speed sign is not visible to drivers until 95 m before the start of the curve. The 85th percentile speed of vehicles on this approach, prior to reaction and braking, has been measured by survey as 88 km/h. If it is assumed that it is desirable for vehicles to slow down to the posted 65 km/h-advisory speed before reaching the curve, what is the required distance to achieve this? Is the available sight distance adequate for this?
A building is located 19 ft from the centerline of the inside lane of a curved section of highway with a 400 ft radius. The road is level; e = 0.10. Determine the appropriate speed limit (to the nearest 5 mph) considering the following conditions: stopping sight distance and curve radius. Assume f= 0.15

The design speed of a multilane is 55kph. What is the minimum stopping sight distance that should be provided on the road if the road is level.
Vehicles arrive at an intersection approach at 550 veh/h at the beginning of an effective red and 15 vehicles are left in the queue from the previous cycle (end of the effective green). Due to peak hour congestion, the arrival rate increases 50 veh/h/min. Therefore after 1 minute, the arrival rate will be 600 veh/h, after 2 minutes it is 650 veh/h. The saturation flow rate of the approach is 1800 veh/h, the cycle length is 65 seconds, and the effective green time is 30 seconds. Determine the total vehicle delay until complete queue clearance. (Assume D/D/1 queuing).
