Speed and density data were obtained by time-lapse photography on a highway. a linear regression analysis is applied to estimate parameters in greenshields’ model of traffic flow. a linear regression model takes the form us = a + bk, where us is space mean speed and k is density. linear regression analysis yields values of the coefficients a = 62.8 and b = – 0.57. determine the jam density (in veh/mi).
