Transition into the electrified transportation sector is being investigated among the feasible
technological resolutions to tackle the mounting climate change issues. Such a transition …

On-road vehicle has been a prominent emission source, hence a key target of control for
environment, health, and climate concerns. While considerable efforts have been made to …

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 …

Energy efficiency is among the main reasons for the increasing popularity of electric
vehicles. Even though they are significantly more efficient in comparison to internal …

Electronic toll collection (ETC) has been designed and implemented to improve traffic
efficiency and reduce traffic-related air pollution. However, the real-world impact of ETC on …

Emission benefits of transit buses depend on ridership. Declines in ridership caused by
COVID-19 leads uncertainty about the emission reduction capacity of buses. This paper …

On-road emissions from urban traffic during interrupted and congested flow conditions are
too high as compared to free-flow condition and often influenced by accelerating and …

Discrepancies between real-world use of vehicles and certification cycles are a known
issue. This paper presents an analysis of vehicle fuel consumption and pollutant emissions …

Nowadays, more and more conventional diesel buses are being replaced by new-energy
buses in many cities in China. Although new-energy buses are more environmentally …

To accurately estimate real-world vehicle emission at 1 Hz the road grade for each second
of data must be quantified. Failure to incorporate road grade can result in over or …
