Summary
This systematic review addresses the persistent challenge of road traffic injuries and deaths, particularly on rural and inter-urban roads, by examining the correlation between road geometry, driver behaviour, and traffic safety. The authors argue that traditional safety interventions rely heavily on geometric compliance and aggregate crash statistics, assuming rational and uniform driver behaviour. However, drivers dynamically adapt their speed, lane position, and risk-taking in response to geometric cues, often in ways not accounted for in standard design guidelines. This disconnect contributes to speed inconsistency, fluctuating driver workload, and elevated crash risks. The study aims to integrate behavioural responses into a standard geometry-behaviour-safety framework, identifying driver behaviour as a critical mediating mechanism between road design and safety outcomes. The methodology involves a comprehensive systematic review of literature published between 1990 and 2025, sourced from major transportation research databases. The review synthesizes existing research on geometry-induced behavioural adaptation, design consistency, and statistical modelling approaches. It analyzes the evolution of safety models from deterministic methods to probabilistic models, such as Poisson and Negative Binomial regressions, and further to advanced techniques including random-parameter, latent-class, and Bayesian hierarchical models. The study also evaluates the application of machine learning (ML) and deep learning (DL) techniques for processing high-resolution trajectory and behavioural datasets. Key behavioural variables examined include speed choice, speed dispersal, lane positioning, acceleration, braking rates, risk perception, and mental workload. The findings indicate that incorporating behavioural indicators significantly enhances safety model performance, improving prediction accuracy by up to 30% compared to fixed-parameter models. Geometric consistency interventions, such as smoother alignment transitions and improved sight distance, have been shown to reduce crash frequency by approximately 15% and speed variance by 12%. Furthermore, targeted design interventions informed by behavioural insights can reduce crash occurrences by up to 20%. The review highlights that perceptual countermeasures, such as delineation and speed feedback signage, offer cost-effective alternatives to physical infrastructure changes, reducing risky speed adaptations by about 10%. However, the integration of Advanced Driver-Assistance Systems (ADAS) and automated vehicles introduces new complexities; inappropriate trust calibration and improper takeover responses in mixed traffic conditions have been linked to an 8% increase in crashes. The significance of this study lies in its recommendation for behaviour-sensitive design standards and hybrid modelling frameworks that combine the interpretability of statistical models with the predictive power of ML. The authors conclude that future road safety research must move beyond two-dimensional geometric analysis to include three-dimensional, real-time behavioural data. Addressing current gaps, such as limited model transferability across different cultural and traffic contexts and the lack of interpretable AI-based safety enhancements, is crucial. The review advocates for policy shifts toward context-specific countermeasures and human-centric transport systems that account for driver cognition, emotion, and adaptation, thereby ensuring more resilient and effective traffic safety strategies.
