Assuming a linear speed-density relationship. the mean free speed is observed to be 65 mph at near zero density and the corresponding jam density is 160 veh/mi. Assume that the average length of vehicles is 20 feet.

a) Write down the equations for speed-density and flow-density relationships

b) Calculate the speed and density corresponding to a flow of 1000 veh/hr

c) Calculate the average time headway and average space headway when the traffic flow is at maximum value

The mean wind speed in San Francisco is 13.6 mph in July, according to the U.S. National Oceanic and Atmospheric Administration. Suppose that the distribution of the wind speed in July in San Francisco is normal with mean μ=13.6 mph and standard deviation σ=6 mph. Find the probability that a randomly chosen day in July has the following wind speeds: 1. 7.2 mph or less 2. Greater than 20 mph 3. Between 15 and 20 mph 4. Tours to Alcatraz...

μ = the population mean speed (mph) of trucks in a specific region in Greeley, CO. A random sample of 8 trucks has a sample mean speed of 25.4 mph and the population standard deviation is known to be 3.2 mph. Find the 95% confidence interval for μ. a.) (23.18, 27.62) b.) (12.68, 18.70) c.) (24.08, 30.05) d.) (18.80, 24.56) What is the required sample size if you want an error margin for the 95% confidence interval for μ to...

A wire with a linear mass density of 1.08 g/cm moves at a constant speed on a horizontal surface and the coefficient of kinetic friction between the wire and the surface is 0.250. If the wire carries a current of 1.31 A westward and moves horizontally to the south, determine the magnitude and direction of the smallest magnetic field that can accomplish this. magnitude ____ T direction ______

A company has observed that there is a linear relationship between indirect labor expense (ILE) , in dollars, and direct labor hours (DLH). Data for direct labor hours and indirect labor expense for 18 months are given in the file ILE_and_DLH.xlsx Treating ILE as the response variable, use regression to fit a straight line to all 18 data points. Based on your results, If direct labor hours (DLH) increases by one hour, the indirect labor expense (ILE), on average, increases...

Assume the speed and density at a freeway location follows a linear relationship.You observe traffic flow rate of 2250 vehicles/hour at 45 mph and 3000 vehicles/hour at 30 mph. What are the jam density, free flow speed (max speed), and capacity of this freeway location? How about the density and speed (i.e., the critical density and the critical speed) at the capacity?

Traffic on a three-lane freeway observes a triangular flow-density relationship with free-flow speed vf=100km/h, capacity c=2000veh/h/lane, jam density kj=150veh/km/lane. Flow in the freeway from upstream is 5000veh/h, while the ramp flow is negligible (almost zero).At 9:45am, an accident occurs at point A. The vehicles involved close one lane of traffic (total capacity reduces to 4000veh/h) for 15min and afterwards the scene is clear (capacity returns to 6000veh/h). Lucy enters the freeway via the ramp at point B at 10:00am. Distance...
