Pedestrian crossings in the UK and US require people to walk at 1.2 m/s to cross the road in time; however a large proportion of older people do not walk this fast, potentially discouraging walking or putting older people at risk of injury. We use longitudinal data to investigate changes in walking speed, and ability to cross the road in time, at older ages. 31,015 walking speed measurements we...

Context Understanding the factors determining impacts of roads and how they fragment landscapes limiting movement animals, is key to implement efficient mitigation measures. Aims Here we investigate if road orientation in relation resources, a largely overlooked factor on impact assessments, can influence animals within landscape where water resources are spatially clustered. Methods We evaluat...

Pedestrians' road-crossing behavior can often interrupt traffic flow and cause vehicles queueing. In this paper, we propose some moving rules for modeling the interaction of vehicles and pedestrians. The modified visual angle car-following model is presented for the movement of vehicles with consideration of the lateral effect of waiting pedestrians. The pedestrians' behavior is summarized as c...

The Namoi River Road Bridge is a colonial era high level wrought iron lattice truss bridge crossing the (Manilla) built in 1886 to replace dangerous river crossing. was part of main road between Sydney (New South Wales – NSW), and Brisbane (Queensland), with opening allowing wool trade from northern extents colony NSW be exported via Port Sydney. six approach spans southern flood plain have his...

Most research on perceptual-motor development has focused on changes occurring during infancy and toddlerhood. In this paper, we describe our work on the development of perceptual-motor development during late childhood and early adolescence in the context of an important applied problem: bicycling across traffic-filled roads. Specifically, we have examined the gaps between cars that children a...

The seemingly intractable issue of level crossing collisions has been the subject of countless industry studies over the years in just about every country of the world. While there has been excellent, robust work from committed and dedicated people, tragically there are still people dying every year. To address this Queensland Rail (QR) has moved beyond the operation of technical silos to form ...

Road networks are important for modelling the urban geographic environment. It is necessary to determine the spatial relationships of road intersections when using maps to help researchers conduct virtual urban geographic experiments (because a road intersection might occur as a connected cross or as an unconnected bridge overpass). Based on the concept of using different map layers to organize...

background and aims: this study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in iran. methods: in a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light cr...

This paper presents a data fusion algorithm which is able to robustly estimate the Time-to-Lane-Crossing (TLC) of a vehicle traveling along a lane on the basis of road images, collected by an on-board videocamera, and kinematic data coming from car sensors. This algorithm is instrumental to built Lane Departure Warning Systems (LDWS) with enhanced predictive capabilities which allow the generat...
