Generate the relationships between concentration, flow and speed on roads. Assess the likely capacity of specific road types in terms of Average Annual Daily Traffic (AADT) and peak flow. Quantify the traffic volumes and patterns on interurban road networks. Quantify the current traffic and safety situation at a specific junction or road. Design alternative traffic signal stagings and timings for simple urban junctions. Describe the process involved in the design of roads. Describe the functions of the different elements of geometric road design. Conduct preliminary design of roads.
