A transportation engineer collected the data shown in the Table below. Develop a linear v-k model, and then establish v-q and q-k relationships. Draw v-k, v-q and q-k diagrams and depict all of the critical values (i.e., free-flow speed, jam density, maximum traffic flow, critical speed and density) in the three diagrams
