“…When we talk about average models, they are used to analyze emissions for each lane or for certain areas, they are based on a scale that includes micro or measurement-type models. Therefore, we can say that the micro model can only analyze emissions from certain areas, roads, or intersections, but the most important assessment is in real-time [ 19 ].…”

A real problem of today’s society is the loss of human lives due to road accidents and the pollution caused by freight transport through metropolitan areas. The restrictions imposed in the near future for freight transport could reduce its efficiency and create many more problems. Using data centralization and developing applications or algorithms dedicated to the freight transportation sectors, routes and emissions can be managed much more efficiently. In this work, general aspects are presented, as well as a route optimization model for freight transport, taking into account the environmental impact, based on a heuristic algorithm, that of the ant colony (ACO). A multitude of studies has focused on what represents the benefits created by the applicability of solutions rather than on generalities and perspectives. The paper aims to highlight the usefulness of an optimization model of freight transport routes and the minimization of time and social costs. The study will show us that an optimized route for freight transport has a huge impact on costs, but also on time efficiency and polluting emissions.

“…For certain pollutant it should be calculated using average operating speed. Furthermore, adjusted average speed due to emission can be calculated using simulation method and parameter adjustments of the speed of running cars [19]. It has been demonstrated that the development of lighter, lower-drag design methods that will make increase of vehicle speed considerably improves fuel efficiency and reduces pollutants.…”

Air pollution is a Worldwide challenge that is a reason for premature death. It affects both developing nations and developed nations. In particular, the air is so much polluted so that cities are fighting to fulfill air quality range and protect humans from harmful substances. One of the greatest global challenges of 2050 is the reduction of greenhouse gas emissions. Besides greenhouse gas emissions, air pollution is the major problems in many urban areas this situation is due to the sudden increase in the count of vehicles. According to the studies, Nitric oxide and particulate matter contribute more to air pollution. Due to urban transportation improvements vehicle traffic volume is on the rise over the past few years. Air pollution is majorly contributed by vehicular congestion and traffic. This paper analyzes traffic data at Coimbatore. From the review, comparing various locations, two-wheelers are the highest in count among all of the rest of the vehicles. Air pollution is a crisis that causes damage to the human who are living in areas where air pollutants are high in level. The type and amount of air pollutant decides the risk of illness. This indicates that carbon monoxide and particulate matter emitted from a vehicle of two passengers is higher than a single passenger vehicle. Although the centralization of poisons close by avenue are not always connected to transportation sector, this marker can be used as an indication of increase in residents. It also acts as an indication of how much surrounding areas are being polluted by metropolitan toxic wastes. This paper examines the vehicular emissions in Coimbatore, India. The study looks at reviewing data from various sources to formulate solutions for improving air quality in the city.

“…For the reasons given, estimation of exhaust emissions of car engines is still an active field of research. Road-related air quality management has based the estimation of vehicular traffic emissions mainly on average speed-based approaches and instantaneous (modal) models [12,13]. The average speed-based approaches rely on emission functions derived from measurements of the emission rates over a wide range of driving patterns at different levels of speed.…”

“…The average speed-based approaches rely on emission functions derived from measurements of the emission rates over a wide range of driving patterns at different levels of speed. Since these approaches do not capture the differences in emissions estimates due to the changes in modal activity, their usual applications concern emission inventories for large geographical areas at the road network level [12]. In turn, the instantaneous (modal) models describe the emissive behaviour of vehicles at the microscale level by relating emission rates to vehicle operation over a short time interval; they usually use vehicle activity parameters to estimate second-by-second emission rates and vehicle fuel consumption [14,15].…”

In line with globally shared environmental sustainability goals, the shift towards citizen-friendly mobility is changing the way people move through cities and road user behaviour. Building a sustainable road transport requires design knowledge to develop increasingly green road infrastructures and monitoring the environmental impacts from mobile crowdsourced data. In this view, the paper presents an empirically based methodology that integrates the vehicle-specific power (VSP) model and microscopic traffic simulation (AIMSUN) to estimate second-by-second vehicle emissions at urban roundabouts. The distributions of time spent in each VSP mode from instantaneous vehicle trajectory data gathered in the field via smartphone were the starting point of the analysis. The versatility of AIMSUN in calibrating the model parameters to better reflect the field-observed speed-time trajectories and to enhance the estimation accuracy was assessed. The conversion of an existing roundabout within the sample into a turbo counterpart was also made as an attempt to confirm the reproducibility of the proposed procedure. The results shed light on new opportunities in the environmental performance evaluation of road units when changes in design or operation should be considered within traffic management strategies and highlighted the potential of the smart approach in collecting big amounts of data through digital communities.
