One of these, termed the engineering effect, refers to the intended effects of a road safety measure on a set of risk factors related to accident occurrence or injury severity.
Having a significant effect of the road lighting and significant interactions, a further analysis was made to test the effects of the road lighting in presence or absence of glare.
We found that exposure to road traffic noise was significantly associated with incident diabetes both before and after adjustment for air pollution, suggesting an independent effect of road traffic noise.
In this work we introduce two new indices: (1) Integral Road Effect (IRE), which measured the sum effects of points in a road at a fixed point in the forest; and (2) Average Value of the Infinitesimal Road Effect (AVIRE), which measured the average of the effects of roads at this point.
Hessler chronicles the effects of an expanding road network on individual lives.
This study characterized the effect of road construction, a human-induced environmental phenomenon, at the scale of Phewa watershed during field work in 2014 with an update of the situation after the extreme rainfall event of July 29 , 2015
An exposure effect of road traffic noise was indicated in the youngest age group (18 - 39 years old) at exposure levels 60 - 64 dB(A) OR 95%CI) 1.47 (1.01-2.14), whereas the estimated effect at higher exposure levels was imprecise (Table 3).
In order to ensure a high level of road safety, road network planning needs to be based on the best knowledge available of the effects of road design on road safety.
Finally, the effect of different road lighting in the presence of glare from an oncoming car was tested.
However, the DNC only lasted for four days, with road closures during a fraction of the day, giving us less power to detect the effect of the road closures.
Furthermore, the past (1962) road network was more important than the recent road network (1981) when explaining forest dynamics between 1981 and 2000, suggesting a long-term effect of roads.
