Five-minute average speed in km/h and flow rate in veh/h during 12 hours were collected from a section of the eastbound lanes of Highway 401 in Toronto. The collected data were plotted to form the scatter diagram shown in the figure below. A curve was drawn to describe the general relationship between speed and flow rate q as shown in the figure. 120 300 Speed km/h 60 1000 Flow Rate vel (a) From the above speed-flow rate curve, determine the...

5. Traffic on Route 15 south of Selinsgrove was observed at two different times. The first observation found a flow rate of 1,863 vehicles per hour per lane and a density of 85 vehicles per mile. The second observation found a flow rate of 1,050 vehicles per hour per lane and a density of 25 vehicles per mile. Using this data, compute the following: a. For both observations, determine the vehicle speed [mph] and the time headway [sec] b. If...

Question-4: Speed-flow-density relationships of a particular site has resulted in the model U = 68.3(1-10) Where U is the speed (mi/hr), and K is the density (veh/hr/lane) Find the following i. Free flow speed and jam density ii. Derive the equation depicting relationship between flow and density Derive the equation depicting relationship between speed and flow iv. Show the values of free-flow speed, jam density and capacity graphically

Question 2 (a) A small electric vehicle is propelled by a motor with the performance data shown in Figure Q2 below. The motor drives a gear with 12 teeth, which in turn drives a larger gear, which is attached to the vehicle's driving wheels. The diameter of the driving wheels is 380 mm and the vehicle is designed for a speed of 30 km/h. (Note: Errors of +10% in reading data from the graphs are acceptable for the purposes of...

1) (35 points) A model of a vehicle suspension system is shown below. The of a 500 kg vehicle is connected to the wheels through a suspension system that is modeled as a spring in parallel with a viscous damper. The wheels are assumed to be rigid and follow the road contour which is also shown below. If the vehicle travels at a constant speed of 52 m/s, what is the acceleration amplitude of the vehicle? m = 500 kg...

The single degree of freedom model of a vehicle shown below will
be used to obtain a first
approximation of the dynamic behavior of the entire vehicle. The
mass m of the vehicle is
1200 kg when fully loaded and 400 kg when empty. The spring
constant k is 400 kN/m and
the damping ratio ζf is 0.4 when the vehicle is fully
loaded. The vehicle is traveling at 100
km/h over a road whose surface has a sinusoidally varying...

Three objects move and their velocity vs time graphs are shown
below
The following questions refer to the velocity vs time graphs
above.
1.Are any of the graphs shown representing objects that are
slowing down?
2.Do any of the objects have a negative acceleration? How can
you tell?
3.Which object’s motion(s) most likely is/are experiencing air
resistance? Explain your reasoning.
4.Sketch what the acceleration vs time graphs would look like
for each of the velocity graphs.

Plot the data for the measurements given below. Being able to create graphs and interpret graphs is an integral part of any science course. You can use the graph paper included in this document, an Excel spreadsheet or your own graph paper. The time measurements are the x-axis coordinates. The temperature measurements are the y-axis coordinates. Space your axes in consecutive intervals such as units of 1,5 or 10. Make sure to label your axes with the appropriate information, including...
