The traffic from a suburban area to a city uses the following five shorter routes, as shown below. Access from Suburban Route 4 Route 1 Route 5 Route 2 Route 3 Access to City The models below show the travel time as a function of traffic flow on each route. t₁ = 18 + 4.5 x₁ t₂ = 21+ 7.0 x₂ t3 = 26 + 4.9 x3 t4 = 29+ 3.4 x4 t5 = 34 + 0.3 x5 Where: t; is travel time on route 'i' (in minutes) and x; is traffic flow on route 'i' (in 1000 vehicles).
A segment of rural freeway is being designed for a FFS of 70 mph through rolling terrain. The directional (i.e. one-way) design volume is 3,000 vehicles per hour. If 10% of the design volume is expected to be heavy vehicles (i.e. trucks and buses), what is the heavy vehicle adjustment used to determine the flow rate? Provide you answer to the nearest hundredths. Response Feedback: f₁ HV 1 1+ · + P ₁ (E₁ − ¹) T T -where PT-0.1, ET=3.0
