1. A transportation engineering study was conducted to determine the proper design of bike lanes. Data were gathered on bike - lane widths and average distance between bikes and passing cars. (Use three decimal places) The data from 9 streets are: Distance 2.4 1.5 2.4 1.8 1.8 2.9 1.2 3 1.2 (m) Lane Width 2.9 2.1 2.3 2.1 1.8 2.7 1.5 2.9 1.5 (m) c. If the minimum safe average distance between bikes and passing cars is considered to be 1.8m, determine the corresponding minimum lane width. d. Using the same data, determine the equation of the best fit 2nd degree curve

Determine the severity number for a section of highway that had 2 fatal crash, 48 personal injury crashes, and 105 property damage only crashes during a particular time period. Use a weighting scheme of 50 for fatal crashes, 25 for personal injury crashes, and 1 for crashes with only property damage. Determine the severity index by dividing the severity number by the total number of crashes, thereby normalizing the severity number by the number of crashes.
