1. Traffic speed is investigated at a certain section of freeway. Mean speed is 73mph. Sample standard deviation was 20 mph. There were 24 samples. A researcher claims the actual speed on that freeway is more than 76 mph. What would be the null hypothesis? null hypothesis= H0: μ=76, Alternative hypothesis= H1: μ>76. One Tail test. This is the only information I was given.

2. Find the critical value

Traffic on a section of an arterial road is flowing at a space mean speed of 40km/hr. The flow of traffic on the road section can be described using the following equation (where q represents flow in veh/hr and k represents the density in veh/km): q = 50 * (k - k^2/150) A slow moving heavy vehicle turns onto the roadway at 2pm, 2km from the beginning of the arterial road, driving at 15km/hr due to its heavy load. The...

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?

Ramp metering is a traffic engineering idea that requires cars entering a freeway to stop for a certain period of time before joining the traffic flow. The theory is that ramp metering controls the number of cars on the freeway and the number of cars accessing the freeway, resulting in a freer flow of cars, which ultimately results in faster travel times. To test whether ramp metering is effective in reducing travel times, engineers conducted an experiment in which a...
