Roundabouts are a kind of at-grade intersection, sought-after for their perceived safety
improvements and potential for traffic flow enhancement. However, the crash statistics of …

Transforming intersections into roundabouts has shown that a sufficient degree of road
safety and traffic capacity can be achieved. Because of the lower speeds at the area of a …

Traffic crashes tend to be more serious when commercial trucks are involved. And an
increasing number of commercial vehicles are equipped with advanced driver assistance …

Roundabouts are considered as one of the most efficient forms of intersection that
substantially reduce the types of crashes that result in injury or loss of life. Nevertheless, they …

Over the past several years, Louisiana has installed quite a few relatively new crash
countermeasures, such as center line rumble strips (CLRS) on rural two-lane highways …

This study examines crash risk factors and develops a severity model for rear-end and angle
collisions in roundabouts and its vicinity in non-lane-based heterogeneous traffic. The rear …

Drivers' safety and overall road functionality are key triggers for deciding on road
interventions. Because of the socioeconomical implications of traffic incidents, either fatal or …

Roundabout crashes are common worldwide but have received little attention. In particular,
the investigation remains relatively understudied in distinct collision modes of roundabout …

Roundabouts reduce fatal and injury crashes at intersections when converted from other
intersection control types. In Wisconsin, roundabouts have been linked to a 38% decrease in …

Research on roundabout safety has shown that roundabouts can significantly reduce fatal
and injury crashes but often lead to an increase in property damage only crashes. Most …
