Unlike KN, these markers are not likely affected by changes in trafficking conditions.
Self-driving cars are just around the corner, and we can start imagining how our daily lives will be changed by the changes in traffic, our schedule, and transportation infrastructure in general.
Based on the planned road closures, we identified highway or road segments that could potentially be influenced in different ways by the changes in traffic volume.
On the other hand, for a range of other infrastructure improvements considered by the study, such as changes in traffic signal program, resurfacing and replacing lenses by LEDs, at junctions, the values of accident reduction factors were not obtained, to a certain extent, due to small samples of sites of those treatments.
It was hypothesised that the significant differences in the studied dependencies were caused by changes in weather conditions because traffic intensity did not differ significantly between the 2 observation years (Erofeeva 2014b).
It is reasonable to rule out confounding by chance variation, long-term trends, changes in traffic volume and regression-to-the-mean.
We attempted to control for changes in traffic volume by including dummy variables for day of the week and for the strata combining year and month, which had been shown to produce estimates of associations between meteorological parameters and traffic accidents in the Netherlands that were consistent with estimates from models adjusted for traffic volume (Brijs et al. 2008).
In this approach, the features that are extracted from traffic measurements by using wavelet transformation are directly utilized in detecting changes in traffic flow.
The finding that SNAT-2 protein expression was decreased in the MVM but not in total placental homogenate strongly suggests that the observed responses are caused by changes in SNAT-2 plasma membrane trafficking, implicating the inhibition of mTORC1 and mTORC2 as the mechanism underlying the decreased MVM SNAT-2 expression in IUGR.
