@eng_james_murithi: Why Curve Phasing in Road Design is Critical (Watch the Video) As a road design engineer, one key concept you must understand is phasing. The coordination of horizontal and vertical curves on a road. Here’s why it’s important: ✅ It helps improve road user comfort and riding quality. ✅ It reduces multiple decision points, confusion, hesitation, and unexpected braking ✅ It improves safety, especially on high-speed roads ✅ It ensures hazards are visible well within the stopping distances If curves are not well-phased, safety challenges can occur: ❌ The road may have 'sharp kinks' and 'depressions', especially in sag curves ❌ Drivers may slow down suddenly due to visual discomfort, causing accidents ❌ Headlight glare is a safety risk, especially in sag curves Always aim to align curves in a way that feels natural and predictable to the driver. This video by @Daniel Findley (edited) takes you through the DOs and DON'Ts in the coordination of Horizontal and Vertical Alignments It's not just about geometry.  It's about safety, flow, and user comfort.
