An Analysis of the Influence of Urban Density on Traffic Accidents

Key Points

• The study aims to systematically analyze the relationship between urban density and traffic accidents using various density metrics.
• Conducted empirical analysis using negative binomial regression on traffic accident data from 226 cities.
• Urban density was subdivided into five metrics: population, employment, business, weekday/weekend resident densities.
• Examined socioeconomic factors including fiscal independence, commercial land ratios, and foreign populations.
• Higher employment density tends to increase traffic accidents.
• In contrast, higher business density is associated with a decrease in traffic accidents.
• Weekday resident density reduces accidents due to regular commuting, while weekend increases correlate with leisure-related accidents.
