Safety effects of signalizing uncontrolled intersections on suburban arterials: An empirical Bayes before-after evaluation by crash type.

Suburban arterial intersections often face safety challenges related to high speeds, mixed road users, and incomplete traffic control. Signalization is a commonly used countermeasure, but existing studies have primarily examined the signalization of stop-controlled intersections, with limited before-after evidence for...

Meso-Level Safety Analysis for Urban Arterials Considering Road Network Characteristics

With the increase in the density of urban road networks, the problem of inappropriate road networks has become increasingly prominent. In particular, improper road connectivity has raised significant safety concerns on urban arterials. Traditional micro-level crash prediction models have explored the relationship amo...
