Chapter 9, Problem 1EDDS

You and your partner have been dispatched to a report of a motorcycle crash on a curvy back road. Fellow riders at the scene reported the patient was travelling too fast to negotiate a sharp curve and was thrown over a guardrail into a tree. They carried the patient up an approximate 4-foot embankment to the road.Upon your arrival, you find a male patient you estimate to be between 20 – 25 years of age, being cared for by a police officer who has opened the airway using an NPA and is administering oxygen via an NRB. The officer reports the patient has been unconscious since she got to the scene. Looking down the embankment, you see the patient’s helmet and note it has sustained significant damage.As you approach the patient, you observe the patient has gross angulation involving his left lower leg and deformity to his right humerus.1. In addition to scene safety, what else would you evaluate during your initial scene size-up?2. What specific information other than that gathered through…

1.. Please show work and steps. If an approach has a PHF of 0.90 and a counted hourly volume of 800 veh/hr what is the maximum 15-minute volume and peak rate of flow? What is the highest and lowest possible value of PHF? At a given location, the space mean speed is measured as 70 mph and the rate of flow as 2200 pc/h/ln. What is the density at this location for the analysis period? How could you decrease the density by 10%?

Calculate the minimum passing sight distance required for a two-lane rural highway that has a posted limit of 72 kph. The local traffic engineer conducted a speed study of the subject road and found the following: Average speed of passing vehicle= 76 kph Average acceleration of passing vehicle= 2.3 kph/sec Average speed of impeder vehicles= 64 kph Show complete solution. Need ASAP. Thank you.
