AASHTO GL-7: Roadway Lighting Design Guide, 7th Edition (2018)
AASHTO GL-7: Roadway Lighting Design Guide, Seventh Edition (2018) provides comprehensive guidance on the planning, design, and implementation of roadway lighting systems. This edition reflects current engineering practices, safety standards, and lighting technologies to enhance visibility, energy efficiency, and operational reliability across modern transportation networks.
Highlights:
- Design principles covering illuminance, luminance, uniformity, and glare control
- Guidance on developing master roadway lighting plans and policies
- Recommended lighting levels for highways, streets, intersections, and pedestrian zones
- Design criteria for tunnels, underpasses, and bridges
- Considerations for temporary lighting in work zones and construction areas
- Evaluation of emerging technologies such as adaptive lighting and smart controls
- Discussion on lighting management systems and energy-efficient solutions
- Environmental impact assessments and aesthetic integration strategies
- Standards for pole placement, maintenance access, and safety
- Support for decision-making with traffic data and community planning considerations
Who It’s For:
An essential reference for transportation agencies, civil engineers, and planners responsible for roadway lighting design and policy development.

AASHTO HB-17: Standard Specifications for Highway Bridges, 17th Edition (2002)
AASHTO HB-17: Standard Specifications for Highway Bridges, 17th Edition (2002) provides comprehensive criteria for the design, construction, and maintenance of highway bridges throughout the United States. This edition is the final update prior to the nationwide adoption of Load and Resistance Factor Design (LRFD) standards.
Highlights:
- General provisions for bridge design, structural analysis, and performance
- Criteria for superstructures, substructures, abutments, culverts, and piers
- Service load and load factor design methods for concrete, steel, timber, and prestressed components
- Requirements for foundations, retaining structures, and soil-structure interaction
- Specifications addressing load distribution, fatigue, seismic considerations, and strength evaluation
- Commentary and notes incorporating interim revisions through 2003
- References to supporting standards from AASHTO, ASTM, AWS, and others
- Applicable to rehabilitation, legacy design validation, and maintenance planning for non-LRFD bridges
Who It’s For:
A critical reference for bridge engineers, transportation officials, and contractors working with legacy structures or evaluating designs developed before the transition to LRFD.
