The safety of river-crossing tunnels is an important aspect of urban road traffic systems. Previous studies concerning traffic safety mainly focused on urban roads. Given the absence of a number of variables, such as speed and real-time traffic volume, in traffic accident databases, the traffic safety of urban river-crossing tunnels has rarely been studied. This study used the microscopic traff...

This paper investigates fatal accidents and fatalities at level crossings in Great Britain over the 64-year period 1946-2009. The numbers of fatal accidents and fatalities per year fell by about 65% in the first half of that period, but since then have remained more or less constant at about 11 fatal accidents and 12 fatalities per year. At the same time other types of railway fatalities have f...

This study reviews the impact of roadside friction on urban arterial roads in published literature and aims to identify various side frictional parameters that roads. The are non-motorized vehicles, pedestrian crossing or moving along road, street vendors, on-street parking, animal movement, land-use activity. all these traffic performance leads a reduction capacity, speed (instantaneous speed,...

Objectives: To propose a novel technique to halt vehicles at the signals before stop line of zebra crossing and allow pedestrians cross road safely. Methods: An advanced automated signal controlling system is developed using controller, various sensors, devices. The bollards are one important parts our system. It used crossing. raised during red phase lowered green phase. Different sensors such...

A novel image-based approach for detecting pedestrian crossings to enhance the safety and mobility of blind people while crossing a road is described. This is achieved through bipolarity-based segmentation and projective invariantbased recognition. A thorough evaluation of the proposed approach was conducted using 100 real images with and without crossings. It was found that the proposed techni...

—Roads represent a pervasive feature on most landscapes that can pose multiple threats to wildlife populations and substantial challenges for management. To be effective, management strategies must often target where threats are most concentrated. Road mortality and nest predation are well-documented threats to Diamondbacked Terrapins (Malaclemys terrapin) across the majority of their range, in...

We examined gap choices and crossing behavior in children and adults using an immersive, interactive bicycling simulator. Tenand 12-year-olds and adults rode a bicycle mounted on a stationary trainer through a virtual environment consisting of a street with 6 intersections. Participants faced continuous cross traffic traveling at 25 mph or 35 mph and waited for gaps they judged were adequate fo...

The extraction of road network is an emerging area in information extraction from high-resolution satellite images (HRSI). It is also an interesting field that incorporates various tactics to achieve road network. The process of road detection from remote sensing images is quite complex, due to the presence of various noises. These noises could be the vehicles, crossing lines and toll bridges. ...

Studies assessing the efficacy of wildlife crossing structures often lead to spurious results because of their failure to address masking effects of confounding variables. Confounding variables include variation in human activity, density of crossing structures along the highway corridor, and equality of species’ perceived access to each crossing structure. We investigated these issues for wide...
