The present study investigates the adoption of predictive methods for road safety in the
Italian context. The main goal of predictive methods is to describe safety performances of a …

Despite widespread recognition of operating speed as a key safety-related variable for
roundabouts, there is no consensus on the best models for capturing the relationship …

This study aims to establish an effective approach for evaluating the safety performance of
road infrastructure. Road safety levels are typically quantified using safety performance …

The purpose of this study is to determine the safety effectiveness of an intervention on an
existing road by using predictive methods. Predictive methods allow the benefit of the …

Roundabouts are considered the safest intersection design; however, the safety effect may
not be satisfactory at each specific roundabout. This is true especially in countries where …

Several types of modern roundabouts are alternatives to standard ones. They are either in
use or at the development stage today. One such intersection is the two-geometry …

Mobility, safety, and environmental sustainability are priorities in the geometric design of
roundabouts. This paper presents a multi-objective optimization model that determines the …

A total of 30 roundabouts with different dimensions and characteristics were selected from
three cities in Jordan. The collected data included the approaching road free flow speed …

With more than 460 roundabouts located in Abu Dhabi, the capital city of the United Arab
Emirates, it is imperative to evaluate the safety benefits provided by those roundabouts. In …

Roundabouts affect operating speeds depending on a number of parameters.
Consequently, their performance affects urban transport systems (safety, environmental and …
