Analyzing the relationship between the efficiency and safety of a turbo roundabout by the factor analysis method [PDF]
The construction of cities and economic development lead to more and more serious environmental pollution, and the concept of green and low-carbon city has been proposed. Therefore, a series of requirements have been put forward for transportation.

ANALYSIS OF SUN GLARE ON ROUNDABOUTS WITH AERIAL LASER SCANNING DATA [PDF]
Road geometry and sun glares play an important role concerning road safety. In this research, the direct sunlight in a roundabout sited in Ávila (Spain) is analysed using Aerial Laser Scanning (ALS) point clouds.

Geometric Design of Suburban Roundabouts
A modern roundabout is an intersection with a circulatory roadway at which the vehicle speed is low, and the traffic is continuous and circulating in one direction around the central island towards the exits at the approach legs. Modern roundabout design

Bi-Level Coordinated Merging of Connected and Automated Vehicles at Roundabouts
Traditional uncoordinated traffic flows in a roundabout can lead to severe traffic congestion, travel delay, and the increased fuel consumption of vehicles.

It is 2015, and what goes around has come around several times in the past 10 years. Back in 2005, Zebedee, or whoever it was who spun the magic roundabout from the Department of Health, seemed confused about the difference between change and progress. Change produced instant good-news stories but constant disruption within the health service. Progress

‘Fix Crash Corner’ – a Roundabout Story
In 2020, a new roundabout was constructed at the intersection of Church and Victoria Streets, Auckland, New Zealand. It replaced a ‘Stop’ controlled cross-roads junction with adverse crash history, nicknamed ‘crash corner’ by locals, having 54 crashes ...
