The RTA Geometric Design Manual for Dubai Roads (2017) is the primary technical framework used to ensure that new infrastructure in the Emirate meets world-class standards for safety and mobility.

- Navigate to the RTA.gov.ae website.
- Go to "About RTA" > "Policies, Strategies, and Regulations."
- Filter by "Roads and Transport" > "Technical Specifications."
- Look for "Geometric Design Manual for Dubai Roads (Issue 4, 2017)".

- Highway and Arterial Design: The manual updates horizontal and vertical alignment criteria for design speeds ranging from 40 km/h (local streets) to 140 km/h (major highways). It introduced stricter standards for stopping sight distance (SSD) in desert environments where sand drift can reduce visibility.
- Intersections and Interchanges: A major overhaul was given to roundabout design (moving away from older UK standards to a more modern, turbo-roundabout concept) and signalized intersections. The manual mandates dedicated left-turn bays with specific taper lengths based on 85th percentile speeds.
- Multimodal (Pedestrian & Cycling): The 2017 update was the first RTA manual to robustly integrate Dubai’s Cycling Master Plan. It specifies minimum clear widths for footpaths (2.0m in commercial areas) and protected cycle tracks (1.5m one-way).
- Drainage & Utilities: While primarily geometric, the 2017 manual coordinates cross-section slopes with Dubai’s strict stormwater drainage standards (e.g., 2.0% to 2.5% shoulder slopes to prevent ponding).
