Seasonal, Weekly, and Diurnal Black Carbon in Moscow Megacity Background under Impact of Urban and Regional Sources

open access: yesAtmosphere, 2022
Moscow megacity has a big gap in assessment of air quality, resulting in severe aerosol pollution. Black carbon (BC) concentrations over different timescales, including weekly and diurnal, are studied during four seasons of 2019–2020 at urban background ...

Modelling Effects of Land Use Changes on Traffic Based on Proposed Traffic Simulator [PDF]

open access: yesComputational Engineering and Physical Modeling, 2019
In this paper, a traffic simulator is designed in order to investigate the travel demand based on GIS data and analysis. In order to evaluate the proposed simulator, four different scenarios are provided for the arrangement of land use services. In first

Open Traffic: A Toolbox for Traffic Research

open access: yesProcedia Computer Science, 2014
AbstractOpen Traffic is an open source software project that provides a transport modeling software environment. While most transport model packages offer ready-to-use modules for end-users, Open Traffic provides open access to a modelling environment for the (further) development of methods and algorithms and enables the sharing, distribution and ...

The effect of social desirability on self reported and recorded road traffic accidents [PDF]

open access: yes, 2010
The use of lie scales has a fairly long history in psychometrics, with the intention of identifying and correcting for socially desirable answers. This represents one type of common method variance (bias introduced when both predictors and predicted ...

Implications of Interdomain Traffic Characteristics on Traffic Engineering [PDF]

open access: yesEuropean Transactions on Telecommunications, 2002
AbstractWe study the interdomain traffic as seen by a non‐transit ISP, based on a six days trace covering all the interdomain links of this ISP. Our analysis considers the relationships between the interdomain traffic and the interdomain topology. We first discuss the day‐to‐day stability of the interdomain traffic matrix to evaluate the feasibility of
