For the Greenshields model, the mean free flow speed on a highway facility lane equals 75 mph near zero density, and the jam density is observed to be about 160 veh/mi. Plot the q-k-u curves in proper order. Write down the speed-density, flow-speed, and flow-density equations. Find out the maximum flow, and also mark it on your diagrams. Compute speeds and densities corresponding to a flow of 2,880 veh/h, describing traffic conditions from a driver’s point of view. Calculate average headways, gaps, clearance, and spacing at CASE 1: maximum flow and at CASE 2: jam density. (Suppose the average vehicle length is 17ft)

Ina road-intersection near Dhaka, average 120 cars make right-hand turns in every hour. Road planner wants to put in a 3-vehicle right- hand turn lane in the intersection to avoid blocking of thru traffic. Determine if 3-vehicle right-hand turn lane satisfy the following design criteria: Red light time of right-hand traffic is 30 seconds Right-hand turn lane must be sufficient 90% of the time.
Traffic volume count has been collected on a 2- lane road section which needs upgradation due to severe traffic flow condition. Maximum service flow rate per lane is observed as 1280 veh/h at level of service 'C'. The Peak Hour Factor is reported as 0.78125. Historical traffic volume count provides Annual Average Daily Traffic as 12270 veh/day. Directional split of the traffic flow is observed to be 60: 40. Assuming that traffic stream consists of 'All Cars' and all drivers are 'Regular Commuters', the number of extra lane(s) (round off to the next higher integer) to be provided, is
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
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?
An existing four-lane freeway in rural area is with the following :information Lane width 3.5m, 0.9m lateral clearance, 1800 veh/hr peak hour volume, PHF=0.9, interchange density =0.90, 5% trucks, 5% buses and the road is within a mountainous terrain. Then based on the HCM procedure, the service flow rate (pc/h/In) is
A signalized intersection has four approaches. If the north, south, east, and west approaches have average control delays of 21, 25, 34, and 32 seconds, respectively, and their respective volumes are 198, 176, 265, and 303 pc/h, what is the intersection LOS?

A minor two-lane road (lane width = 3.4 m) intersects a four-lane divided highway (lane width = 3.5 m) at 90° forming a T-intersection. The median width on the major road is 1.75 m. The design speeds on the major and minor roads are 90 and 60 km/h, respectively. (a) Determine the minimum sight distance required for a single-unit truck on the minor road to depart from a stopped position and turn left onto the major road. (b) Determine the sight distance required by the minor-road a single-unit truck to safely complete a right turn onto the major road.
What distance will a vehicle travel before coming to a complete stop from a speed of 70 mph, (a) When the vehicle is traveling on a level roadway with no grade, (b-1) When the vehicle is traveling uphill on a roadway of constant grade = 0.10, (b-2) If the roadway grade is not constant but starts at 0.10 uphill and decreases to 0 at a continuous rate, would the braking distance be equal to, greater than, or less than that in the case of a constant 0.10 uphill grade (briefly explain why) (c) When the vehicle is traveling downhill on a roadway of constant grade = 0.10. Assume a perception-reaction time of 2.5 seconds, and an a/g value equal to 0.35.
