Accurate estimations and assessments of vehicle emissions can support decision-making
processes. Current emission estimation tools involve several calculation methods that …

This study investigated the effects of passenger load, road grade, and congestion level on
the fuel consumption and emissions from a Euro VI compressed natural gas (CNG) urban …

Abstract Tehran, a city with 8.5 million inhabitants, has suffered from rapid and unplanned
urbanization in recent years resulting in substantial environmental impacts perhaps fore …

A fuel-based approach is used to estimate long-term trends (1990–2010) in carbon
monoxide (CO) emissions from motor vehicles. Non-methane hydrocarbons (NMHC) are …

Coupling a traffic microsimulation with an emission model is a means of assessing fuel
consumptions and pollutant emissions at the urban scale. Dealing with congested states …

Modeling is an essential tool for the development of atmospheric emission abatement
measures and air quality plans. Most often these plans are related to urban environments …

Objectives Air pollutant concentrations in many urban areas are still above the legal and
recommended limits that are set to protect the citizens' health. Madrid is one of the cities …

Emissions from mobile sources have become a major concern for health, environmental
sustainability and climate change and high-resolution inventories are needed to support the …

This paper presents the evaluation of emissions from vehicle operations in a domain of 300
m× 300 m covering a complex urban roundabout with high traffic density in Madrid. Micro …

The regular and robust collection of traffic data for the entire road network in a given country
will usually require high-cost investment in traffic surveys and automated traffic counters …
