- Yawi Freeway is a four lane road located in the Metro where trucks, buses, and rvs can be found aside from passenger cars. At some point further along the roadway there is a 5.7% upgrade that is 1.5 km long. If the traffic stream has 25% large trucks and buses and 5% recreational vehicles, what is the heavy vehicle adjustment factor?4. TXDOT is working on the design of I-69 north of Victoria. They project a demand volume of 52,000 vehicles per day with a K factor of 0.12 and a directional distribution of 56/44 in level terrain with a target LOS of B and 17% trucks and buses. They plan to have roughly one diamond interchange every 2 miles. What number of lanes is required to achieve these design requirements? What LOS would occur for a typical 4-lane rural interstate design? DHV = AADT * K * D DHV – design hourly volume AADT - average annual daily traffic K- peak hour adjustment factor D- directional distribution (make design conservative)ramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.9. If the road is expanded to four 11-foot lanes with a 2-foot right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and peak-hour factor, what is the new LOS and estimated density? P-22 Chapter 6 Problems hour. What would be the LOS before and after the heavy vehicles are allowed on the upgrade (assuming 50% SUTs and 50% TTs.)? 6.21 A multilane highway has four lanes (two lanes in each direction) and a measured FFS of 55 mi/h. The directional peak-hour volume is 1900 vehicles (the peak-hour factor is 0.80). One upgrade is 5% and is 0.62 mi long. Currently, heavy vehicles are not permitted on the highway, but local authorities are considering allowing heavy vehicles on this upgrade. If this is done, they estimate that 150 heavy vehicles will use…
- If Vf = 2327 VPH with 9% trucks, VR1 = 653 VPH with 5% trucks, and VR2 = 594 VPH with 8% trucks, what is the passenger car equivalents (Vpcph) of the onramp? Assume that the roadway is urban.a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 11-ft lanes with a 4-ft right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 10% large trucks and buses and 2% recreational vehicles. the driver population factor has been estimated at 0.95. what will the los on this highway be on a 4% upgrade that is 1.5 miles long if the speed limit is 55 mph and there are 15 access points per mileYou are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75.000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88 and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least level of service D using the 30th highest annual hourly volume (K30+ 0.12). The answer is a number of lane freeway.
