How SHC 101 Aligns with International Standards to Improve Road Safety in Saudi Arabia

‍

Saudi Arabia is undergoing a transformative phase in its infrastructure development, driven by the ambitions of Vision 2030. One of the cornerstones of this transformation is the modernization and expansion of the country's road and highway network. At the forefront of this initiative stands the Saudi Highway Code (SHC), particularly SHC 101 – General, which serves as the foundational document guiding all aspects of highway planning, design, construction, operation, and maintenance across the Kingdom.

‍

But what makes SHC 101 particularly noteworthy is its alignment with internationally recognized standards, particularly those from the American Association of State Highway and Transportation Officials (AASHTO). This alignment plays a critical role in elevating road safety and ensuring uniformity in highway development across Saudi Arabia.

The Need for SHC 101: Addressing Fragmentation in Road Safety Standards

‍

Before the SHC, Saudi Arabia's road infrastructure development was governed by a patchwork of standards. Various government entities, such as the Ministry of Transport and Logistic Services (MoTLS), municipal authorities, and industrial commissions, operated under different frameworks. This fragmented approach often led to inconsistencies in road design, safety implementation, and maintenance practices.

‍

The lack of a unified system had real-world consequences, notably:

‍

• Inconsistent road safety measures.
• Variability in construction quality.
• Increased operational risks for road users.

‍

To solve these challenges, SHC 101 was developed as a comprehensive, cohesive, and authoritative guide, aligning with global best practices while being tailored to Saudi Arabia's unique geography, climate, and socio-economic conditions.

‍

Alignment with International Standards: AASHTO as the Benchmark

‍

One of the key highlights of SHC 101 is its deep integration with AASHTO standards, which are globally recognized for their rigor and effectiveness. The alignment with AASHTO provides the SHC with:

‍

• A performance-based approach to road safety.
• Design and construction practices validated by decades of international use.
• A framework that accommodates technological advancements, such as intelligent transport systems (ITS) and geographic information systems (GIS).

‍

This strategic alignment ensures that Saudi Arabia’s road infrastructure is not only modern and safe but also capable of competing on an international scale.

‍

Key Elements of SHC 101 that Enhance Road Safety

‍

1. Unified Lifecycle Approach

‍

SHC 101 covers the entire lifecycle of highway projects, from planning to decommissioning. This end-to-end perspective ensures:

‍

• Consistency in safety standards across different project phases.
• Better integration of safety audits and inspections at every critical juncture.
• Reduced risk of oversight or misalignment during design and construction.

‍

2. Mandatory Safety Protocols

‍

SHC 101 defines a clear distinction between mandatory and advisory requirements:

‍

• Words like "must", "shall", and "will" indicate legal obligations.
• Words like "may", "should", and "would" provide advisory flexibility.

‍

This clarity eliminates ambiguity, enhancing enforceability and compliance across all agencies and contractors.

‍

3. Road Safety Audits (RSA) at All Stages

‍

SHC 101 mandates four levels of Road Safety Audits:

‍

• RSA 1: Preliminary Design
• RSA 2: Detailed Design
• RSA 3: During Construction
• RSA 4: At Opening

‍

These audits ensure that potential safety hazards are identified and mitigated early, reducing accidents and enhancing public trust in the system.

‍

4. Inclusion of Vulnerable Road Users

‍

The SHC recognizes the importance of planning for pedestrians, cyclists, and other non-motorized users. Design parameters now integrate:

‍

• Dedicated lanes
• Safe intersections
• Enhanced visibility and lighting

‍

These design inclusions help reduce accidents involving vulnerable road users, a critical road safety indicator.

‍

SHC 101’s Multidisciplinary and Consultative Development Process

‍

The success of SHC 101 lies in its inclusive and transparent development. The drafting process engaged:

‍

• Subject Matter Experts (SMEs)
• Legal teams
• Municipal and national stakeholders
• Public and private sector engineers and designers

‍

This broad engagement ensured that the SHC:

‍

• Accounts for real-world application challenges.
• Receives cross-government support for implementation.
• Is rooted in practicality while reflecting global excellence.

‍

Local Adaptation with Global Insight

‍

While SHC 101 draws heavily from international benchmarks like AASHTO, it is also customized to Saudi Arabia’s local needs:

‍

• It addresses desert terrain, mountainous regions, and high temperature zones.
• It incorporates cultural, behavioral, and economic factors.
• It allows for deviation and relaxation in cases where standard implementation may not be feasible—subject to formal approval.

‍

This balance of international rigor and local flexibility ensures the SHC is both adaptable and effective.

‍

Digital Accessibility and Continuous Updates

‍

All SHC volumes, including SHC 101, are made available via an official online platform, ensuring:

‍

• Easy access to current standards for all stakeholders.
• Transparent update procedures.
• Collaborative inputs for continuous improvement.

‍

Stakeholders can propose updates, which are then reviewed and approved through a formal governance structure led by the Roads General Authority (RGA).

‍

Contribution to Saudi Vision 2030

‍

The SHC directly contributes to the Kingdom’s Vision 2030 by:

‍

• Improving transportation infrastructure quality.
• Enhancing road safety and efficiency.
• Positioning Saudi Arabia as a logistics hub connecting Asia, Africa, and Europe.
• Promoting sustainable and environmentally conscious road construction.

‍

Conclusion

‍

SHC 101 is a monumental step toward achieving international excellence in road safety and infrastructure in Saudi Arabia. By aligning with globally accepted standards like AASHTO and adapting to local realities, it creates a robust, unified framework that ensures roads across the Kingdom are not only safe but also future-ready.

‍

Its structured lifecycle approach, stringent safety mandates, inclusive development process, and emphasis on digital transformation collectively represent a new era of road governance and safety in Saudi Arabia.
