Rtageometric Design Manual For Dubai Roads2017 Pdf New May 2026

The Geometric Design Manual for Dubai Roads, referencing AASHTO standards and local practices, acts as the primary technical guide for road planning, design, and construction. It defines critical parameters, including road hierarchy, lane widths of 3 to 3.75 meters, and specific sight distance requirements.

Design Vehicles & Control – Updated turning radius and swept path analysis for modern truck and bus fleets operating in Dubai.
Cross-Section Elements – New lane width standards (typically 3.65m for mainline arterial), shoulder widths, median design (including crash-tested barriers), and kerb types.
Horizontal & Vertical Alignment – Tighter criteria for sight distance (stopping, passing, and intersection), superelevation rates, and curvature coordination to accommodate higher design speeds (up to 120 km/h for major highways).
Intersections – Detailed warrants for roundabouts (discouraged on high-speed facilities) versus signalized intersections; channelization island designs; and U-turn criteria.
Interchanges – New guidance on ramp design (direct, loop, semi-direct), acceleration/deceleration lengths, and auxiliary lanes.
Pedestrian & Bicycle Facilities – Mandatory provision of footpaths, elevated/at-grade crossings (signalized and unsignalized), and dedicated cycle tracks (aligned with Dubai Cycle Master Plan).
Public Transport Integration – Bus bay design, bus priority lanes, and shelter placement at intersections.
Drainage & Utilities Coordination – Integration with stormwater networks and utility corridors to avoid conflicts with geometric layout.
Traffic Control Devices – Signing, marking, and signal head placement as part of geometric design (not an afterthought).

Conclusion The RTA Geometric Design Manual for Dubai Roads (2017) is a foundational document that codifies safe, efficient, and context-sensitive geometric standards. It supports Dubai’s ambitions for a world-class transportation network by offering designers a clear technical framework while leaving room for adaptive, future-focused updates. As Dubai’s transport needs continue to evolve, iterative revisions that incorporate new modes, technologies, and resilience measures will ensure the manual remains a relevant tool for sustainable urban mobility. rtageometric design manual for dubai roads2017 pdf new
