1. A fransportation engineering study was conducted to defermine 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) a. Manually plot the data (draw to scale) b. Fit a straight line to the data with linear regression. Add this line to the plot.

a) At certain on-street parking, determine the number of parking spaces required to park vehicles in angles (0°, 45°, and 90° degree) if the length of the curb =240 ft, then show the layouts with dimensions. b) Briefly describe the classification of parking facilities and the methodology of parking studies. c) A traffic engineer records the travel times for six vehicles (1.35, 1.15, 1.75, 1.4, 1.8, and 1.4 minutes). These vehicles are traveling a 0.75-mile segment of a highway. Determine space mean speed (SMS) and time mean speed (TMS).
Estimate the maximum number of cars in a single lane of traffic that would pass a check-point in one hour at an average speed of 50 mph. Safe driving practice requires one car length of spacing for each 10 mph speed. (a) Layout the procedure for making the estimation including assumptions, diagrams, equations, etc.
