BACKGROUND It is principally the area of enforcement that offers the greatest opportunity for reducing alcohol-impaired driving in the near future. How much of a reduction in drinking and driving would be achieved by how much improvement in enforcement intensity? METHODS We developed logistic regression models to explore how enforcement intensity (6 different measures) related to the prevalen...

The paper studies the complementarity of the methods from the field of traffic flow theory: methods of traffic flow intersecting intensity and the method for the at-grade intersection capacity analysis. Apart from checking mutual implications of these methods, the proportionality of mutual influences is assessed. Harmonized application of these methods acts efficiently on the entire traffic net...

It is by now widely accepted that the arrival process of aggregate network traffic exhibits self-similar characteristics which result in the preservation of traffic burstiness (high variability) over a wide range of timescales. This behaviour has been structurally linked to the presence of heavy-tailed, infinite variance phenomena at the level of individual network connections, file sizes, tran...

The instantaneous, average, and critical speeds of vehicles passing through the Kamchik pass were determined in this article. law safe movement traffic flow has been developed. research results on determining speed different categories mountain conditions are presented. To ensure safety, depending condition road surface dangerous areas road, recommendations given limits signs to be installed.

Vehicle Color Recognition System is the implementation of automatic detection of predominant color of vehicles from the traffic images captured through CCTV cameras installed at crossings. This document presents a new effective method for extracting color of vehicle using MATLAB, Firstly vehicle is cropped automatically from the traffic image and then color of individual vehicle is picked accor...
