Humans live interacting with other people and do everyday tasks in individual and collective ways. Robotics people are interested in building robots that can interact with people in the same way that humans do. In order to reach this goal robots must learn from the interaction with humans and learn the human skills used in everyday life to acquire robot social behaviors that can then be used in...

OBJECTIVES Environmental factors associated with winter outdoor falls are poorly understood. This study describes the demographic, spatial and temporal distribution of outdoor falls that occurred in Laval and Montréal Island (Canada) in relation to meteorological conditions. METHOD Data on falls, including geographic coordinates, were obtained from ambulance services (December 1, 2008 to janu...

Route generation is an ideal subject for studying the interactions of spatial and temporal reasoning in a practical setting. Starting from a cognitive study of pedestrian route descriptions in urban environments generated by human subjects, we identified the main requirements for a knowledgebased-system that would generate and describe routes in a cognitively plausible way. In this paper we pre...

A system of signalized intersections is a critical element in the smooth operation of both arterial and urban street facilities. The amount of vehicular and pedestrian traffic which can be processed by a system of intersections depend on a) characteristics of the traffic and pedestrian stream, b) traffic control measures, c) various physical and operating characteristics of the roadway and d) t...

conclusions it is proposed that the needed research be conducted at national and regional levels in coordination and cooperation with international organizations active in the field of traffic crashes in various parts of the world, especially in asian, african and latin american developing countries, where a greater proportion of pedestrian traffic crashes occur. results a review of the studies...

We demonstrate that random walks embed connected undirected graphs into Euclidean space, in which distances and angles acquire the clear statistical interpretation. Being defined on the spatial network of Venetian canals, random walks afford a portrait of the city space syntax and measure its intelligibility. In the present Letter, we investigate the spatial network of 96 canals in Venice (that...

Autonomous vehicles are an emerging technology that will play a significant role in shaping transport systems in the decades to come. Consequently, implications are anticipated for societal issues ranging from transport safety to congestion, from energy consumption to the allocation of public and private lands. Driverless technology will undoubtedly influence other transport modes, too. With th...

Walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.Today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

OBJECTIVE Different sources are available for the surveillance of Road Traffic injuries (RTI), but studied individually they present several limits. In this paper we present the results of a surveillance integrating healthcare data with the data gathered by the municipal police in the southeastern area of Rome (630,000 inhabitants) during the year 2003. METHODS The Municipal police RTI report...
