WebWhile this is a common way of linearizing data, a far more common approach is to use logarithms. Logarithms can also be used to linearize data and are seen throughout the literature in the form of log-lin plots, where … WebModified Greenshield's model describes the speed-density relationship of a traffic stream by dividing entire traffic state into two regimes. Speed and density data are collected to calibrate the parameters of this model in a field study. Speed values are: 55, 48.1, 44.8,40.1, 37.3, 35.2, 34.1, 272, 20.4, 17.5, 14.6, 13.1, 11.2 and 8 km/hr. The
