You Ve Been Contracted By The City Of Corvallis To Verify The Design Of A Traffic Circle To Help With Traffic Congesti 1 (44.85 KiB) Viewed 20 times

You've been contracted by the city of Corvallis to verify the design of a traffic "circle” to help with traffic congestion on highway 20. Upon review of the plans, you realize the shape actually an ellipse, not a true circle. The plans say the traffic ellipse has a 130 A radius in one direction and 200 ft radius in the other. The speed limit in the traffic circle is 35 mph. What is the maximum acceleration experienced by drivers in the circle expressed in g's? Note: 1g is 9.81 m's Note: This was not intended as a math exercise, but an applicable real-world problem. You may derive the radius of curvature from the equation in class (this is how it's done in problem 12-139 from the book), it's a great exercise in algebraic manipulation. However, this is a math intensive course, not a mathematics course. For your convenience, you may start from the equation: NEUE 1 + p = b azya Then determine the maximum acceleration For convenience, the equation for an ellipse is: + = 1 Supplemental Questions: Is this value reasonable, why or why not? Assuming it wasn't, what would be your recommended change?
