1. FIGURE Q1 shows Highway 82 network connecting Town X and Y. The highway is currently having LOS C and the government authority plans to develop an industrial area Z as shown in the figure. It is predicted that the new traffic demands generated by the industrial area would decrease LOS of the highway. Therefore, a new highway is planned to connect Town X, Town Y and the industrial area Z. Moreover, a railway is also planned to shift some travel demands of Town X to Town Y, Town X to Industrial Area Z, and Town Y to Industrial Z. Plan the new highway including the justifications on the type of highways and number of lanes. Analyse the Annual Average Daily Traffic (AADT) of Highway 82 from TABLE Q1a and adjust the AADT from the permanent counter station. Justify the Design Hour Volume (DHV) using information in TABLE Q1b. Outline the process in designing the cross-sections of the new highway with appropriate Level of Service (LOS). Use the traffic volume information in APPENDIX I.
