. In three sentences or less, explain why traffic density and speed are related.

Expert Solution

The relationships between speed and traffic density are not difficult to observe in the real world they are relate to each other .while the effects of speed and density on flow are not quite as apparent.Under uninterrupted flow conditions, speed, density, and flow are all related by the following equation:

q = k*v

                          Where
                            q = Flow (vehicles/hour)
                           v = Speed (miles/hour, kilometers/hour)
                          k = Density (vehicles/mile, vehicles/kilometer)

Because flow is the product of speed and density, the flow is equal to zero when one or both of these terms is zero. It is also possible to deduce that the flow is maximized at some critical combination of speed and density.

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...

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
