- The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.The road alignment for the construction of a highway passes through a mountainous area. There is therefore the need to embark on a slope stability analysis for the safe and economical design of the slope. Outline the procedure you will go through to achieve this purpose.Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?
- The C-5 Southlane Freeway/Expressway having 6 lanes (three lanes in each direction) is 3.6m wide per lane and has an edge distance of 2 m to the nearest obstruction. A total of 26 on-or off-ramps within the 40 km span, from which 3 ramps are located within 5 km upstream and 4 ramps within 5 km downstream from the midpoint of the analysis segment can be observed. Determine the free-flow speed of the existing freeway, in kph. Do not round-off your FFSThe 3 eastbound lanes of a rural freeway segment have 11 ft lane widths. There is a 3 ft lateral clearance on the right side of the road. There are no ramps within the influence area. What is the estimated FFS (mph)? Provide your answer to the nearest tenths.A particular roadway segment has a 6000-ft section of 3% upgrade, followed by a 5000-ft section of 5% upgrade. The traffic on the road includes 8% trucks and 4% recreational vehicles. Determine the PCEs.
- A vertical curve was designed in 2006 for SSD requirements at a design speed of 120 km/h to connect grades G1 = +1% and G2 = -2%. The curve is to be redesigned for 120 km/h design speed in the year 2050. Vehicle braking technology has advanced such that vehicle deceleration rate has increased by 40% relative to 3.4m/s2 value used in the original design. However, due to the higher percentage of older people in the driving population, design reaction times have increased by 20%. Also, because vehicles have become smaller, the driver’s eye height is assumed to be 0.9 m above pavement. Compute the difference in design curve lengths for the 2006 and 2050 designs. Assume heye =1.08 and hobs = 0.60 m.9) The driver of an automobile moving with the velocity of 90 km/h on a 4% graded descendinghighway section decides to overtake the bus moving with a velocity of 70 km/h despite theapproaching truck with a velocity of 50 km/h on the opposite direction.a) What should be the minimum distance between the automobile and the truck at thebeginning of the overtaking for safe manouevre ?b) If the truck has to stop op the highway, what is the upper and the lower limit of the tractionforce that must be diverted to its wheels in order to restart moving ?Given: di=8+0,2.Vi; pavement sliding coefficient, f=0,40; t = 0,020; the mass of the truck = 12ton, Qm=2/3.QA 960-m segment of 5.4-km six lane divided TWLTL multilane highway in a suburban area is at a 1.5% grade. The highway is in level terrain and lane widths are 3-m. The peak-hour volume is 3500 veh/hr/ln, PHF is 0.90, and there are 13% trucks and 2% RVs. Determine the LOS for the following:(a) extended directional segments (b) 3% upgrade(c) 4% downgrade
- A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 4-ft shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has only regular users, there are 8% large trucks and buses (no recreational vehicles), and it is on rolling terrain with a peak-hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway’s AADT?If a four legged roundabout has 8 conflict points, how many does a 3 legged roundabout?
