BACKGROUND Particulate air pollution has been consistently linked to increased risk of arterial cardiovascular disease. Few data on air pollution exposure and risk of venous thrombosis are available. We investigated whether living near major traffic roads increases the risk of deep vein thrombosis (DVT), using distance from roads as a proxy for traffic exposure. METHODS AND RESULTS From 1995 ...

Transport infrastructure plays a central role in rural development, yet little is known about the size and especially the distribution of benefits from road investments. This paper develops and implements a method for nonparametrically estimating the benefits from road projects at the household level using the relationship between the value of farmland and its distance to agricultural markets. ...

This paper presents a method for road extraction from lidar data based on SVM classification. The lidar data are used exclusively to evaluate the potential in the road extraction process. First, the SVM algorithm is used to classify the lidar data into five classes: road, tree, building, grassland, and cement. Then, some misclassified pixels in the road class is removed using the road values in...

We examine the relationship between cell phone use and traffi c accidents using a unique measure of cell phone coverage. The distance from an antenna tower accurately predicts whether or not an area has cellular coverage according to provider coverage maps in 2016. Cellular coverage between 2001 and 2011 is proxied for using the the distance between a road segment and the nearest antenna tower....

plants polluted with pb produced by automobiles along the roads and highways have extensively been reported all over the world. it is the most important source of pollution in the environment. this research was carried out to determine the polluting degree of plants along the highways such as: rasht-anzaly, kelachay-ramsar, tehran-karaj, and isfahan-tehran. at each arbitrary point, a transect 1...

We describe the problem of automated steering using computer vision, focusing the analysis and design on appropriate lateral controllers. We investigate various static feedback strategies where the measurements obtained from vision, namely offset from the centerline at some lookahead distance and the angle between the road tangent and the orientation of the vehicle at some lookahead distance, a...

The objective of our study was to measure the impact of transportation-related noise and total environmental noise on sleep disturbance for the residents of Montreal, Canada. A telephone-based survey on noise-related sleep disturbance among 4336 persons aged 18 years and over was conducted. LNight for each study participant was estimated using a land use regression (LUR) model. Distance of the ...

We provide the most comprehensive study to date on the correlation between network centrality measures and vehicular movement flows, using a model of the UK’s entire road network (2,031,971 nodes) and a very large dataset of vehicular movement counts (20,752 instances, evenly distributed over the UK’s territory). We describe the statistical associations between observed vehicular flows and the ...
