Roadway Geometric Design - Horizontal Curve Analysis

A technical roadway design project focused on horizontal curve geometry using Transportation Association of Canada (TAC) standards. The project involved designing simple curves for local road designation with precise calculations for curve radius, point of curve (P.C.), center of curve (C.C.), and right-of-way requirements. The design ensured compliance with all TAC safety standards including stopping sight distance, decision sight distance, and maximum gradient requirements.

Applied TAC geometric design standards to create horizontal curve layouts, calculated curve radii (R=130m, R=120m), determined point of curve locations, designed right-of-way widths (minimum 20.00m), and prepared technical drawings showing centerline geometry and curve details. Ensured all designs met TAC standards for 70km/h design speed including minimum stopping sight distance of 85-420m and decision sight distance of 170-235m.

Delivered complete roadway geometric design meeting all TAC standards with maximum gradient of 6-11%, minimum stopping sight distance of 85-420m, and appropriate curve radii. The design achieved minimum 30.00m intersection distance from point of curve and established proper right-of-way widths determined from street centerline. All dimensions calculated to 2 decimal places precision, demonstrating professional engineering standards.
