A six-lane multilane highway (three lanes in each direction) currently operates at maximum LOS C conditions. The measured FFS is 55 mi/h. The highway is on rolling terrain with 14% SUTs and 6% TTs, and the peak-hour factor is 0.92. If 17% of all directional traffic occurs during the peak hour, determine the total directional traffic volume.

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
