How do speed breakers influence vehicular emission?
Best insight from top research papers
Speed breakers play a significant role in influencing vehicular emissions. Studies show that traditional speed breakers can lead to increased emissions due to factors like noise pollution, air contamination, and vehicle wear and tear . On the other hand, modern automated speed breaker systems have been found to reduce emissions by improving traffic flow efficiency, reducing delays, travel times, fuel consumption, and emission rates compared to conventional speed breakers . The speed of vehicles is a crucial factor affecting emissions, with higher speeds generally resulting in increased emissions of pollutants like CO2, NOx, and particulate matters . Proper spacing and design of speed control devices like speed humps and tables can help maintain lower speeds, thereby reducing emissions and noise levels on local streets .

How to estimate ship emission?5 answersEstimating ship emissions can be achieved through various methods outlined in the research papers. One approach involves utilizing a bottom-up modular ship emission modeling system (MoSES) that calculates emissions based on ship position data, engine characteristics, and emission factors. Another method is the Ship Emissions Assessment (SEA) method, which combines ship track density data and average voyage information to estimate emissions accurately and efficiently, making it a cost-effective and resource-efficient solution. Additionally, remote sensing techniques like long-path differential optical absorption spectroscopy (LP-DOAS) measurements can be used to monitor ship emissions in real-time, providing valuable data for emission rate calculations without requiring knowledge of fuel consumption. By employing these methods, stakeholders can make informed decisions to mitigate the detrimental effects of ship emissions on climate change and human health.
Why are emission invetories so important?5 answersAccurate emission inventories are crucial for informed decisions about emission control strategies. Emission inventories provide estimates of the amount of pollutants released into the atmosphere from various sources. They help in understanding the sources and levels of pollution, identifying trends, and assessing the effectiveness of emission reduction measures. Emission inventories are used by policymakers, researchers, and regulatory agencies to develop and evaluate air quality management plans. They also serve as a basis for modeling and predicting air pollution levels, which is important for assessing the impact of emissions on human health and the environment. Additionally, emission inventories help in identifying areas and sectors that require targeted emission reduction efforts. Overall, accurate emission inventories are essential for effective air pollution control and management.
What are the emissions of car exhausts?4 answersCar exhaust emissions include nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs), hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). These emissions are released into the air during the combustion of fuels in vehicle engines. The composition of car exhausts can vary depending on factors such as the type of engine, fuel, and combustion process. The emissions from car exhausts have adverse effects on the environment and human health. To reduce the harmful effects of car exhaust emissions, various techniques are used, including the use of catalytic converters that convert toxic pollutants into less harmful substances. Additionally, the use of monitoring portable sensors has been employed to determine the composition of car exhausts and evaluate their impact on human health.
What is the emissions breakdown from the electronics industry?5 answersThe emissions breakdown from the electronics industry includes significant metal emissions such as copper, lead, and antimony. Bromine emissions are also present due to the presence of brominated flame retardants in the waste. Emissions of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) were found to be below regulatory limits, possibly due to the presence of bromine in the waste stream. The embodied emissions in electronic goods imported to the US have increased over time, primarily driven by increased consumption of computers and peripherals, audio/video equipment, wireless communications equipment, and various components. The international transport and wholesaling/retailing portions of the supply chain also contribute to emissions. The electronics industry is under pressure to reduce its environmental impact, and performance measures are being developed to assess environmental performance and practices. The industry also generates a high demand for raw materials that are considered scarce or rare, such as precious metals and rare earth elements.
Can we generate electricity from speed breakers?3 answersYes, electricity can be generated from speed breakers. Several studies have been conducted on this topic, exploring different mechanisms for power generation. One approach is to use the weight and momentum of vehicles passing over the speed breaker to produce electrical power. This can be achieved by employing mechanisms such as rack and pinion, slider-crank, and gear drives to convert the reciprocating motion of the speed breaker into rotary motion, which can then be used to generate electricity. Another method involves using a hybrid energy system, which combines multiple energy sources, such as potential energy, piezoelectricity, and hydraulic systems, to generate electricity from the movement of vehicles over the speed breaker. These approaches offer a cost-effective and sustainable way to generate electricity from the mechanical energy of vehicles, making speed breakers a potential source of renewable energy.
How exhast emission from vehicels are controlled?3 answersExhaust emissions from vehicles are controlled through various methods. One approach is to determine the emissions of the vehicle and the current driving conditions, and then adjust the engine and/or exhaust gas treatment accordingly to maintain emissions below a threshold value. Another method involves cutting off the connection between the engine and the transmission system when the catalyst temperature is below the ignition temperature. In this mode, the engine provides energy for the catalyst while a motor connected to the transmission system provides torque output. Additionally, vehicles can be designed to automatically switch to a reduced-emission mode when they enter a designated reduced-emission zone, thereby reducing emissions for a given drive power. These methods aim to improve fuel efficiency while effectively reducing vehicle exhaust emissions.
