Evaluating emission mitigation strategies for sustainable transportation system: a system dynamics approach
The sustainable development of urban transportation system demands a trade–off between economic, social, demographic, geographic, and political concerns. To address these concerns there is a need of induction of viable transportation policies. In order to examine, the effect of these policies, a system dynamics modelling framework has been presented. A simulation model has been developed to ...

Air Pollution and Traffic: Monitoring Strategies for Reducing Emissions in Big Cities
TL;DR - Vehicle emissions comprise a significant portion of global air pollution, with vehicles responsible for a wide range of pollutants known to be harmful to human and environmental health - including particulate matter, nitrogen dioxide, volatile organic compounds, and ground-level ozone. Traffic-related pollution is made worse by idling and traffic congestion, which causes a build-up of ...

Analysis of the impacts of an environmental traffic management system on vehicle emissions and air quality
Environmental traffic management systems (ETMS) are implemented to improve air quality in urban streets. They allow for a situation-related control of light signal systems to optimise road capacities and enhance traffic flow in street sections. Therefore, they are equipped with mitigation strategies and continuously provided with traffic and air quality data. In this context, it is ...

Explaining vehicle emissions – why do laboratory and road measurements differ?
The road transport sector is a major contributor to Europe’s emissions of greenhouse gases and air pollution. For certain pollutants, vehicles can emit substantially higher emissions on the road than official emissions tested in laboratories. A report released today by the European Environment Agency (EEA) provides a non-technical guide that describes the reasons for these often significant ...

Prediction of energy consumption of passenger transportation and GHG emissions in Jordan
In this paper, the structure of the Jordanian transport sector is analysed with focus on passenger cars, which represent 65% of total vehicles and responsible for almost all of the national gasoline fuel demand. In order to achieve the objectives of this study, an empirical model is developed based on multivariate linear regression analysis to identify key drivers that influence gasoline ...

What are clean air zones and how do they affect HGV drivers?
Clean Air Zones are popping up more and more around the country in order to try and reduce the pollution in the area. This means that charges are put in place for certain vehicles that want to pass through the zone. For many, this can be avoided, but for HGV drivers, this could be a difficult and costly minefield to negotiate. Whilst the importance of Clean Air Zones is clear, the impact on those ...
