This TRAC PAC 2 module combines mathematics, social studies and technology so students can better understand all the factors in Highway Design and Construction. Through five activities students will learn data visualization, law of sines, societal impact of transportation systems, and computer algorithms. Road capacity, design consequences, budgets, and environmental impact must be considered when students are asked to design and build a new roadway. To do this, students will utilize spreadsheets, computer-based modeling, and real estate pricing tools. Mathematics will be applied to road design using High Roads CAD software to create a road and explore curves. Intelligent Transportation Systems (ITS) concepts of sensors, traffic management systems and software engineering are also introduced.
