Density (k) and space mean speed (vs) data have been collected from a traffic survey for a k specific highway and the expression: kf is developed to describe the speed- V₁ = V fe density relationship. Where, Vs space mean speed (km/hr) V₁ = mean free flow speed (km/hr) k = density (veh/km) k;= jam density (veh/km) 1.a (5 marks) In order to estimate the free flow speed and jam density of the highway, transform the speed-density expression into a linear format to complete a linear regression analysis. Identify the independent variable, dependent variable, and the parameters you would estimate through the regression analysis. (Note: Do not complete the regression analysis, only complete the transform) Please Ignore the box below and provide the solution in the answer sheet that you will be uploading.
