IRC:86: Geometric design for urban roads. Lower design speeds than rural highways because of: frequent intersections, pedestrians, mixed traffic, right of way constraints. Arterials: 60–80 km/h; sub-arterials: 50–60 km/h; collector: 40–50 km/h; local: 30 km/h. Pedestrian safety: provides footpaths, crossings.
