Saudi Arabia’s rapid infrastructure expansion, driven by Vision 2030, relies heavily on the Kingdom’s ability to deliver both long-term strategic road corridors and short-term highway upgrades. With major growth concentrated around economic and industrial hubs such as Jubail, Yanbu, NEOM, and the Riyadh metropolitan region, highway planning has become one of the most critical pillars of national development.
A key enabler of this progress is the integration of surveying standards, mapping frameworks, and geospatial reference systems that ensure consistency and accuracy across all road projects. Modern digital tools such as AI-powered road infrastructure monitoring platforms are also helping authorities analyse highway performance and infrastructure conditions across national road networks.
Strategic highway planning refers to long-term infrastructure development aligned with national economic and transport priorities. In Saudi Arabia, strategic planning focuses on identifying and developing corridors that:
• connect major urban centres
• support industrial and logistics zones
• enhance regional and international trade routes
• improve access to ports, airports, and economic cities
• enable sustainable national mobility growth
Advanced digital infrastructure tools such as AI road network monitoring systems allow authorities to analyse corridor performance, detect congestion patterns, and support long-term strategic planning.
Short-term highway planning addresses immediate transport needs driven by traffic demand, urban expansion, or operational constraints.
Typical short-term highway projects include:
• road widening and capacity upgrades
• interchange redesigns
• pavement rehabilitation programs
• temporary bypass and diversion construction
• safety improvements in high-risk areas
Technologies such as AI-based road damage detection platforms help authorities quickly identify pavement failures and infrastructure deterioration, enabling faster maintenance planning.
Accurate highway surveying forms the foundation for both strategic corridor development and short-term road improvements.
The Saudi Highway Code (SHC 202) establishes approved surveying methodologies, equipment standards, and geodetic reference systems required for highway projects across Saudi Arabia.
Without consistent surveying control, highway projects may face:
• alignment conflicts
• construction inaccuracies
• incomplete infrastructure documentation
• inefficient long-term maintenance planning
Infrastructure intelligence tools such as AI pavement condition monitoring systems support ongoing asset evaluation and improve long-term highway maintenance planning.
Saudi Arabia’s highway development framework relies on modern surveying technologies and national spatial standards.
Terrestrial surveying determines precise locations of highway features including carriageways, drainage structures, and roadside assets. This method is widely used during detailed design and construction stages where high positional accuracy is required.
Highway surveying across Saudi Arabia is based on the Saudi Arabia National Spatial Reference System (SANSRS).
This national framework ensures that all infrastructure projects operate within a consistent coordinate system, allowing geospatial datasets to integrate seamlessly across agencies and regions.
The KSA-CORS network provides Real-Time Kinematic (RTK) positioning services that deliver centimetre-level accuracy for highway survey operations.
GNSS-based surveying allows engineers to efficiently capture spatial data across large-scale corridor developments and regional highway networks.
Topographic surveys support feasibility studies, preliminary design, and detailed engineering analysis by producing:
• digital terrain models (DTMs)
• contour maps
• corridor constraint analysis
These datasets allow engineers to optimise route alignment while considering environmental and construction constraints.
Surveying activities defined under SHC 202 support the full lifecycle of highway development.
Early planning stages focus on corridor identification using:
• satellite imagery
• aerial photogrammetry
• reconnaissance-level topographic surveys
These methods help planners evaluate economic feasibility and potential alignment options.
During the preliminary design stage, surveyors establish foundational control systems through:
• GNSS ground control networks
• Total Station traverses
• integration with national GIS databases
This phase supports route optimisation and geometric design validation.
Detailed design and construction represent the most survey-intensive stage, including:
• high-resolution mapping
• detailed surface modelling
• construction staking and setting-out
• calibration and localisation procedures
Technologies such as AI-powered construction monitoring systems support real-time project tracking and ensure alignment accuracy during highway construction.
Surveying continues after construction through:
• deformation monitoring
• pavement condition surveys
• digital twin integration
• periodic asset re-surveys
Asset management platforms such as roadside infrastructure inventory systems help authorities maintain accurate records of highway assets and roadside infrastructure.
SHC 202 defines strict requirements for survey accuracy and measurement quality.
Key standards include:
• horizontal accuracy of RMSExy ≤ 0.25 mm at map scale
• vertical accuracy consistent with approved contour intervals
Survey errors must be controlled through:
• instrument calibration
• redundant observations
• data validation and adjustment procedures
These processes minimise systematic, random, and blunder errors across all highway development phases.
Modern highway planning in Saudi Arabia relies on GIS-based data integration across multiple agencies.
Survey deliverables must include:
• GIS-compatible raster and vector datasets
• CAD engineering drawings
• standardised metadata documentation
• compliance with SANSRS coordinate systems
AI-based traffic analytics tools such as traffic behaviour monitoring platforms allow agencies to integrate infrastructure and traffic datasets into GIS-based planning systems.
The Saudi Arabia National Spatial Reference System (SANSRS), managed by the General Authority for Survey and Geospatial Information (GASGI), provides a unified geodetic framework for all national infrastructure projects.
Benefits include:
• reduced duplication in infrastructure planning
• improved inter-agency data compatibility
• enhanced infrastructure reliability
• stronger long-term asset management
Unified mapping frameworks are essential as Saudi Arabia accelerates infrastructure development under Vision 2030.
Strategic and short-term highway planning in Saudi Arabia extends far beyond road construction. It requires precise surveying standards, advanced mapping technologies, and integrated geospatial frameworks that support efficient infrastructure development.
The Saudi Highway Code (SHC 202) provides a robust technical foundation ensuring that highway projects meet the Kingdom’s economic, transportation, and sustainability objectives.
As Saudi Arabia continues to expand its national transport network, adherence to these standards will help deliver safe, reliable, and future-ready highways.
Advanced infrastructure intelligence solutions such as AI road safety risk analysis tools further support safer and smarter highway development by identifying high-risk locations and enabling proactive safety improvements across national road networks.
