An undivided multilane highway segment has two 11 ft lanes in the eastbound direction with no shoulders and a 55 mi/h speed limit. This highway segment has 40 access points on a 1.25 mikes, 2.5% upgrade. During the highest 15 minutes of traffic flow within the peak hours there are 755 vehicles and 12% of these are heavy vehicles with a 70%/30% mix of single-unit and tractor-trailer trucks. What are the estimated speed, density, and level of service of upgrade?
