• Addresses gaps in current VIA methodologies through systematic integration of visual pollution assessment. • Propose a two-stage framework combining landscape character assessment and environmental theories. • Identifies seven visual perception variables linked to specific perceptual impacts of visual pollution. • Integrates evolutionary and cultural perspectives for comprehensive viewer response assessment. Highway landscapes play a multifaceted role in modern infrastructure, providing environmental mitigation and cultural expression while impacting viewers’ experiences and well-being. However, these landscapes face challenges from visual pollution, which can compromise their aesthetic appeal and functionality. This study proposes a comprehensive conceptual framework that addresses gaps in current visual impact assessment methodologies, particularly in systematically capturing how viewers interpret and respond to visual pollution in highway landscapes. While NCHRP (NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM) Report 741 established evaluation criteria and FHWA (Federal Highway Administration) Guidelines offered procedural guidance, neither fully addresses the complex relationship between visual pollution and viewer perception. Our framework integrates multiple environmental theories with landscape character assessment principles, identifying land use, landform, and land cover as fundamental elements and seven visual perception variables (openness, naturalness, complexity...
