that have updated the 2017 manual.
The RTA classifies roads based on their specific utility, balancing the competing needs of mobility (speed and throughput) and accessibility (access to properties).
Dubai Municipality also handles various road-related standards, often aligned with the RTA 0.5.1. Conclusion
The 2017 edition focuses heavily on three pillars:
Often collaborates on road and infrastructure standards. rtageometric design manual for dubai roads2017 pdf new
Determined based on the design speed and the maximum allowable superelevation rate to counteract centrifugal forces.
Context and Purpose Dubai’s unprecedented growth over recent decades has demanded a comprehensive, consistent approach to road design. The RTA manual provides standardized criteria that align with international best practice while addressing local needs: high summer temperatures, sand encroachment, heavy growth in mixed-use developments, and a multicultural road user population. By codifying parameters like design speed, lane widths, sight distances, superelevation, and roadside clearances, the manual helps reduce design ambiguity, promote interoperability across projects, and improve long-term maintainability.
Geometry must include dedicated left-turn and right-turn auxiliary lanes with sufficient storage length to prevent queue spillover into through-lanes.

Applied at complex locations like major freeway splits, interchanges, and toll (Salik) zones, giving drivers extra time to maneuver. 3. Cross-Section Elements
: Focuses on the "clear zone" concept to minimize hazards for vehicles running off the road. Accessing the Manual
To help find specific design parameters or sections within the manual, let me know: g., Expressway vs. Local Road)?
The distance required for a driver to bring a vehicle to a complete stop before reaching a hazard, factored against Dubai’s specific pavement friction coefficients under high temperatures. Conclusion The 2017 edition focuses heavily on three
Designing roadway cross-sections and intersections to sustain high levels of service (LOS) even during peak hours.
Streets that collect traffic from local areas and distribute it to the arterial network.
RTA Geometric Design Manual for Dubai Roads 2017: A Comprehensive Guide
Prior to the issuance of the 2017 manual, infrastructure design in Dubai relied heavily on a mixture of international codes, predominantly the American Association of State Highway and Transportation Officials (AASHTO) standards and the British Standards (BS). While these frameworks provided a solid foundation, they lacked optimization for the unique challenges of the Arabian Gulf, such as extreme thermal variations, rapid sand accumulation, and hyper-accelerated urban growth.
Primary routes connecting different districts with partially controlled access and signalized junctions.
