High NO2 Concentrations Measured by Passive Samplers in Czech Cities: Unresolved Aftermath of Dieselgate?

open access: yesAtmosphere, 2021
This work examines the effects of two problematic trends in diesel passenger car emissions—increasing NO2/NOx ratio by conversion of NO into NO2 in catalysts and a disparity between the emission limit and the actual emissions in everyday driving—on ...

Study of traffic volumes

open access: yesInternational journal of health sciences, 2022
"The area of transportation planning deals with transportation facilities (usually streets, roads, walkways, bike lanes, and public transit lines)." It is vital to assess the present state of traffic volume and anticipate the future state of traffic volume in this field traffic volume survey.

Automated Machine Learning Pipeline for Traffic Count Prediction

open access: yesModelling, 2021
Research indicates that the projection of traffic volumes is a valuable tool for traffic management. However, few studies have examined the application of a universal automated framework for car traffic volume prediction.

Accumulation of Major, Minor and Trace Elements in Pine Needles (Pinus nigra) in Vienna (Austria)

open access: yesMolecules, 2021
Increasing heavy metal pollution in the environment and the fact that pine needles are good bio-monitors for air pollutants was the reason to investigate their accumulation in pine needles in Vienna (Austria).

Study of time indicators of public transport operation depending on the season of the year

open access: yesTransport Technologies, 2023
Mobility problems in large cities of Ukraine and Eastern Europe are complicated by the fact that the increase of private transport volume significantly exceeds street and road network`s capacity.

Factors Determining Seasonal Variations in Traffic Volumes

open access: yesArchives of Civil Engineering, 2017
The characteristics of seasonal variations in traffic volumes are used for a variety of purposes, for example to determine the basic parameters describing annual average daily traffic – AADT, and design hourly volume – DHV, analyses of road network ...

Modeling Highway Traffic Volumes [PDF]

open access: yes, 2007
Most traffic management and optimization tasks, such as accident detection or optimal vehicle routing, require an ability to adequately model, reason about and predict irregular and stochastic behavior. Our goal is to create a probabilistic model of traffic flows on highway networks that is realistic from the point of applications and at the same time ...

Intelligent Transportation System Using Multi Stream Feature [PDF]

open access: yesITM Web of Conferences
Traffic flow prediction accuracy is very important for intelligent transportation systems (ITS). Many studies have proposed different methods for traffic flow prediction including ARIMA, ANN and SVM.
