The design stopping sight distance of a circular highway segment is 370 feet. The travel lane width is 12 feet and the radius of the highway centerline (R) is 290 feet. There is an obstruction blocking drivers' eyesight. Calculate the minimum required clearance distance (C) between the travel lane edge and the obstruction, as shown in the figure below. (Round UP to the nearest foot and fill in the blank with a number only.) -G.. C sight obstruction R 12 ft

To "tailgate" is to follow another vehicle at an unsafe distance. Detail the many problems that arise from tailgating.
A vertical bar screen is constructed of 20-mm diameter bars that have a clear spacing of 25 mm. Determine the headloss and velocity through a clean screen when the channel approach velocity is 1.0 m/s. For the previous, we assume that the bar screen is at 90o angle from the horizontal. If the screen is inclined at a 50, 55, and 60° angle from the horizontal, how will the headloss and velocity through the clean screen be impacted? Hint: using a spreadsheet will allow you to quickly calculate the headloss and velocity at different angles.
