Understanding the Highway Planning Process in Saudi Arabia

‍

Highway planning is a critical aspect of Saudi Arabia's infrastructure development, directly influencing the Kingdom's economic growth, public safety, environmental sustainability, and social mobility. Governed by the Saudi Highway Code (SHC), particularly SHC 201, the planning process is a comprehensive, multi-layered framework that integrates strategic vision, technical precision, and community needs. This blog explores the various stages, considerations, and methodologies used in the highway planning process in Saudi Arabia, based on the SHC 201 documentation.

Overview of the Highway Planning Framework in Saudi Arabia

‍

The SHC 201 outlines the foundational framework for planning highways in both urban and rural contexts. It emphasizes the importance of mobility and accessibility and integrates transportation needs with public policies on urban growth, economic development, and environmental conservation.

‍

The planning process involves:

‍

• Understanding socio-demographic, land-use, and economic contexts
• Vision development
• Goal and objective setting
• Performance measurement
• Data collection and analysis
• Strategy evaluation
• Programming and implementation
• Project development and system monitoring

‍

Major Phases of the Transportation Planning Process

‍

SHC 201 details the step-by-step process used by planners:

‍

• Context Understanding: Analyzing current land use, demographics, and economic indicators.
• Visioning: Developing a shared vision that reflects economic, environmental, and accessibility goals.
• Goal Setting: Establishing objectives that align with national and regional development.
• Data Analysis: Gathering and analyzing existing and forecasted traffic and infrastructure data.
• Alternative Evaluation: Assessing different strategies for improvement.
• Programming: Matching desired actions with available funding.
• Project Development: Refining selected strategies for implementation.
• Monitoring: Evaluating effectiveness and refining plans accordingly.

‍

Key Planning Considerations

‍

SHC 201 introduces a wide range of considerations that influence highway planning:

‍

• Urban Highway Planning: Multimodal integration, functional classification, land-use alignment, and connectivity.
• Strategic (Long-term) Planning: Typically covers a 20-year horizon, includes safety, congestion, infrastructure condition, and environmental sustainability.
• Implementation (Short-term) Planning: Focuses on 5-year Transportation Improvement Programs (TIPs) to address urgent needs.
• Corridor Planning: Detailed studies focusing on specific routes for future expansion, safety, and congestion issues.
• Sustainability: Emphasis on environmental impact mitigation and climate-conscious designs.
• Safety Planning: Integration of crash data, safety performance indicators, and countermeasures.
• Stakeholder Engagement: Extensive collaboration with local authorities, law enforcement, environmental groups, and the general public.
• Freight Transport: Emphasis on supporting economic activities through efficient goods movement.
• Special Event Planning: Ensuring the highway system can accommodate surges in traffic during large-scale events.

‍

Functional Classification of Highways in Saudi Arabia

‍

Saudi highways are classified into:

‍

• Freeways: Fully controlled-access roads, primarily for long-distance travel.
• Principal Arterials (Expressways): Limited-access roads connecting key urban centers.
• Minor Arterials: Serve moderate-distance trips and connect collectors to expressways.
• Collectors: Link local roads to arterials, facilitating internal area circulation.
• Local Roads: Primarily provide direct land access with lower traffic volumes.

‍

Each classification has distinct design standards, speed regulations, and land-use considerations as specified in SHC 301 and SHC 603.

‍

Integration with Urban Planning and Public Transport

‍

SHC 201 stresses the integration of highway planning with urban development and public transport systems. Highlights include:

‍

• Designing highways to support transit-oriented development (TOD)
• Encouraging walkability and bike-friendly infrastructure
• Developing feeder and trunk transit networks in conjunction with highway layouts
• Reducing vehicle kilometers through compact, mixed-use development

‍

Non-Motorized User and Accessibility Considerations

‍

Inclusive infrastructure is prioritized with specific planning for pedestrians and cyclists:

‍

• Safe sidewalks and crossings
• Dedicated bicycle lanes
• Accessibility features for people with disabilities
• Encouraging active transport as part of sustainable mobility

‍

Planning for Highway Capacity

‍

Capacity planning ensures that highways meet future demand without overloading the system:

‍

• Level of Service (LOS) analysis
• Highway capacity modeling
• Design controls based on traffic volume projections

‍

Data, Monitoring, and Continuous Improvement

‍

Planning does not end with implementation. Continuous monitoring helps refine future strategies:

‍

• Crash and congestion data analysis
• Public feedback loops
• Regular updates of long-term and short-term plans (typically every 5 years)

‍

Conclusion

‍

Saudi Arabia's highway planning process is a model of thoroughness, balancing long-term vision with short-term action. Governed by the SHC 201 and associated volumes, it promotes safety, sustainability, inclusivity, and economic development. With growing urbanization and national transformation goals under Vision 2030, the Kingdom's highway infrastructure planning will continue to play a pivotal role in shaping the nation’s future.
