Developing Non-skid Road Surfaces

In the second direction, accompanying this outdoor ex­ posure, will be the standard laboratory tests on these same materials after they have been subjected to freezing and thaw­ ing, wetting and drying. Such laboratory work will, when compared to the outdoor experiment, tell us whether or not it is necessary to go through the actual construction of a test road in order to find out what may othe...

On the mutual relatedness of evenness measures

Several evenness measures have been proposed for quantifying the distribution of abundance among community species, but none seems to be generally preferred. Since these measures have the common objective of summarizing community structure, they may be expected to be intercorrelated. In this paper, seven standard measures of evenness were calculated for 65 sample plots of ruderal vegetation wit...

Predicting Road Conditions with Internet Search

Traffic congestion is an important problem both on an individual and on a societal level and much research has been done to explain and prevent their emergence. There are currently many systems which provide a reasonably good picture of actual road traffic by employing either fixed measurement points on highways or so called "floating car data" i.e. by using velocity and location data from roam...
