Improving roundabouts for cyclists and visually impaired
Roundabouts are continuing to increase due to their high traffic safety, low delay times and their winning design. However, there are also problems related to roundabouts; the traffic safety for cyclists is unclear or even negative and there are reports of accessibility problems for people with …

Do Roundabouts Work? An Evaluation for Uniform Approach Demands
With the increased prevalence of roundabouts in the United States, there is a need to evaluate the performance of roundabouts relative to other intersection control strategies. Few studies have compared roundabouts with other intersection control strategies in a systematic fashion. Consequently, …

Innovációs minták a design-vezérelt iparágakban. A nyílt Made in Italy = Innovation Patterns In the Design-Driven Industries: Opening Up The Made In Italy
… the findings presented, despite the swirls and roundabouts of discussion with which I explicitly intend to deepen our understanding of the fields discussed. I am not less eager to challenge, and at some points even entertain by adding dimensions to flat writing. I invite the Reader to jump into …

Evaluation of PC-Based Virtual Reality as a Tool to Analyze Pedestrian Behavior at Midblock Crossings
… reality to analyze pedestrian behavior at roundabouts. Although this study showed that PC-driven virtual reality is not effective in replicating pedestrian walking speeds or pedestrian observation patterns at a midblock crosswalk, researchers may expect PC-driven virtual reality to have …

A framework for smart traffic management using heterogeneous data sources
… optimisation procedure for determining missing roundabouts and urban roads flow distribution using constrained optimisation. Existing imputation methodologies have been developed on straight section of highways and their applicability for more complex networks have not been validated. This task …

Roll and Yaw Stability Evaluation of Class 8 Trucks with Single and Dual Trailers in Low- and High-speed Driving Conditions
… in places where tight turns occur—such as in roundabouts—are closely examined in a simulation study in order to evaluate the elements that could cause large vehicle body lean (or high rollover index), besides the truck elements that have most often been studied. Two roundabout geometries, …

Development and Testing Of The iCACC Intersection Controller For Automated Vehicles
… vehicle classes/models, shared movements, roundabouts, and passenger priority. In addition, the iCACC is capable of capturing the heterogeneity of roadway users (cyclists, pedestrians, etc.) using a video detection technique developed in this dissertation effort. It is anticipated that the …

Heterogenous motorised traffic flow modelling using cellular automata
… controlled and uncontrolled intersections and roundabouts. In this heterogeneous model (binary mix), space mapping rules are used for each vehicle type, namely long (double-unit length) and short (single-unit length) vehicles. Vehicle type is randomly categorised as long (LV) or short (SV) with …

EVALUATION AND MITIGATION OF THE RISK OF ROAD ACCIDENT IN URBAN AREAS ACCORDING TO TECHNIQUES BASED ON HUMAN-ROAD INTERACTION
… The road elements considered are intersections (roundabouts and T-junctions) and pedestrian paths.

Influence of accelerator pedal force feedback on truck drivers' speed control
… between the two drivers when negotiating roundabouts. A new mathematical model of the human driver’s longitudinal control was also developed to include the driver’s cognitive control of the accelerator pedal. Model Predictive Control theory, commonly used for modelling the driver’s …

Peripheral Transverse Pavement Markings for Speed Control
… driving situations such as work zones, curves, roundabouts, and toll plazas. Evaluations are required in order to determine the effectiveness of these various treatments at reducing speeds. This research project explored several possible perceptual countermeasures to try on the approaches to …

Mind wandering during everyday driving
… situations that are usually demanding, such as roundabouts. Although there is an inverse association between patterns of mind wandering and the places where most crashes happen, there is no evidence that mind wandering causes crashes. Findings from this research support theories of mind …

Estudio de la influencia de determinadas variables en el ruido urbano producido por el tráfico de vehículos
… facade shape. Intersections: traffic lights and roundabouts. This research consists of measuring all variables existing in a big city which could have some influence on acoustic pollution as well as the noise level in a large city as Madrid. This is accomplished by fieldwork in which all …

Upgrading of Milner and Klipfontein Road Southbound Approach to alleviate traffic issues
… Rotary movement control which refers to roundabouts or traffic circles, can handle larger volumes of traffic and reduce conflicting movements. They are therefore, considered much safer than other forms of at-grade intersections. The literature review will provide more detail regarding …
