PV-Alert: A fog-based architecture for safeguarding vulnerable road users

2017

International audience; High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert (Pedestrian-Vehicle Alert) where fog nodes process delay sensitive data obtained from smartphones for alerting pedestrians and drivers before sending the data to the cloud for further analysis. Fog computing is considered in developing the architecture since it is an emer…

An overview of safety effects on pedestrians at modern roundabouts

2011

Pedestrians are important users of the transportation system, but most guidelines have given them little importance in the geometric design of roads and intersections. In these cases it can be difficult for vehicles and pedestrians to share the road safely, particularly at intersections where vehicle-pedestrian conflicts (and the risk of vehicle–pedestrian crashes) can be a frequently recurring situation even with low pedestrian volume. In a sustainable safety vision road system planning and design must include engineering choices that help to improve the sharing of road space between vehicles and pedestrians, as well as for other vulnerable users. It is known that modern roundabouts are sa…

Pedestrian Safety Indicators Study

2008

Pedestrian mobility can be considered an important feature in a new model of town organization, being suitable for the newly urbanized areas as well as the old quarters and the outskirts, places where streets and squares, once devised for a pedestrian based mobility, were eventually overcame by an ever increasing motorized traffic. Enhancing pedestrian mobility could bring new life and activities into the old and historic parts of the town reviving their original identities. The last decade’s increase in the recourse to private cars requires improvements in pedestrian mobility quality. This can be achieved by building new infrastructures, limiting the use of private cars, improving public t…

Pathways and pedestrian crossings: indicators of quality and safety

2014

Pedestrian mobility can be considered an important feature in a new model of town organization. Enhancing pedestrian mobility could bring new life and activities in the old and historic parts of the town reviving their original identities. The planning of new quarters is often performed considering a wide use of private cars, this resulting in urban highways and long and winding local roads hindering pedestrian mobility and safe-ty. Town social features and mobility purpose, related to pedestrian age, are important elements to define the Pedestrian Safety Indicators. Using a GIS software, an evaluation of risk was carried out along a main urban road in order to study and develop measures to…

Identification of factors increasing the risk of pedestrian death in road accidents involving a pedestrian with a motor vehicle

2023

Walking is a basic form of activity for every human being and has many advantages, including health, economic and environmental benefits. Every journey made using various means of transport begins and ends on foot. As is well known, the group of road users particularly exposed to the risk of serious injury in road accidents, apart from cyclists, also includes pedestrians. These are the so-called vulnerable road users. Pedestrians are a group of road users that is often deprecated by many drivers of motor vehicles, but very important in road traffic. Pedestrian injuries and pedestrian fatalities have enormous social and economic consequences. The problem of high pedes-trian risk on Polish ro…

Safety effects on pedestrians at urban roundabouts: an overview

2013

Pedestrians are important users of the transportation system, but most guidelines have given them little importance in the geometric design of roads and intersections. Thus it can be difficult for vehicles and pedestrians to share the road, particularly at intersections where vehicle-pedestrian conflicts can be frequently recurring situations even with low pedestrian volume. In a sustainable safety vision, pedestrians and vehicles are required to safely share the road; thus the need that roads have a recognizable design and predictable traffic situations where users know what they should do and what they can expect from other users, should be even more deeply felt. It is well-known that mod…
