Revisiting TODs: How Subsequent Development Affects the Travel Behavior of Residents in Existing Transit-Oriented Developments

This reactive approach overlooks the many near-miss incidents and perceived hazards that occur daily but go unrecorded. Understanding such incidents is essential for proactive transportation safety planning, allowing for interventions before injuries or fatalities occur. However, current practice lacks a systematic way to collect and analyze near-miss data, creating a critical g...
