Electric vehicles (EVs) are gaining popularity as a low-emission and cost-effective alternative to conventional cars. But how can they be used in public transportation? In this article, you will learn about some of the benefits and challenges of integrating EVs into public transit systems, and some of the best practices and examples from around the world.
One of the main benefits of using EVs in public transportation is reducing greenhouse gas emissions and air pollution. EVs have zero tailpipe emissions, which means they do not produce carbon dioxide, nitrogen oxides, particulate matter, or other harmful pollutants that affect human health and the environment. By replacing diesel or gasoline buses and trains with EVs, public transit agencies can contribute to mitigating climate change and improving air quality in urban areas.
Another benefit of using EVs in public transportation is lowering operational and maintenance costs. EVs have fewer moving parts and require less frequent servicing than conventional vehicles. They also have lower fuel costs, as electricity is cheaper and more stable than fossil fuels. Additionally, EVs can benefit from smart charging strategies, such as using renewable energy sources, demand response, or vehicle-to-grid technologies, to optimize their energy consumption and reduce peak demand.
The complete life cycle of vehicles is essential in assessing transport sustainability. Factors such as fuel efficiency, manufacturing and energy sources influence vehicle environmental impact. Electric vehicles (EVs), powered by renewable energy, typically have lower carbon footprints than traditional internal combustion engines. Battery manufacturing carries environmental implications, the emissions during EV operation, especially with renewable energy sources like solar or wind power, often offset this initial footprint. With a 15-year life cycle in focus, EVs powered by renewables emerges as the most sustainable choice. Advancements in battery technology and recycling enhance EV sustainability will solidify eco-conscious transportation.
Os veículos elétricos s?o uma solu??o sustentável para os desafios do transporte público em grandes cidades, trazendo benefícios ambientais, econ?micos e sociais. No entanto, a falta de infraestrutura de recarga é uma dificuldade crucial. Uma solu??o para essa dificuldade é a implementa??o de um plano abrangente de infraestrutura de recarga, envolvendo parcerias entre o governo, empresas de energia e operadores de transporte público.
Apart from direct impact in reducing greenhouse gas emissions and air pollution, electric vehicles in public transport can help alleviate traffic congestion by reducing the number of individual vehicles on the road. This, in turn, can contribute to smoother traffic flow, shorter travel times, and reduced overall congestion-related emissions.
EVs hold a crucial entry point in reducing public transport-related emissions. Public transport is geared towards reducing reliance on private or low-capacity vehicles and eventually reducing emissions per passenger kilometer. EVs can be deployed in all aspects of public transport: from buses to trams, trains, motorcycles, tricycles, taxis, and water vehicles where applicable. They are important in alleviating tailpipe emissions, by replacing ICE vehicles used in public transport systems. This will help reduce GHGs and improve overall urban air quality.
One item I believe is of paramount benefit is overcoming the perception of EVs in public transit as a novelty and more as a norm. The energy placed within the vehicle is often inconsequential in comparison to consumer demand for convenience. While there are many positive values to EVs, and we can speculate on congestion reductions, the majority of American consumers will still hop in their SOVs and head to the pump. The greatest benefit EVs can provide in public transit right now can be addressing the symptoms of SOV use by partnering with gov’t agencies and/or private firms to promote enabling legislation for supportive and more convenient public transit infrastructure.
However, using EVs in public transportation also poses some challenges that need to be addressed. One of the main challenges is the high upfront cost of purchasing and installing EVs and their charging infrastructure. EVs are still more expensive than conventional vehicles, and their batteries have limited lifespan and capacity. Moreover, EVs require adequate and accessible charging stations, which may involve upgrading the existing grid, securing land use permits, and coordinating with utility providers.
Another challenge of using EVs in public transportation is the uncertainty and variability of their performance and reliability. EVs are sensitive to weather conditions, traffic congestion, driving patterns, and passenger loads, which can affect their range and efficiency. EVs also have different operational and safety requirements than conventional vehicles, such as driver training, fire protection, and emergency response. Therefore, public transit agencies need to plan and monitor their EV fleets carefully, and adapt to changing conditions and customer needs.
Desde mi punto de vista el principal desafio está en el metodo de carga adoptar. - ?Solo en el deposito? - ?En distintas puntas de linea de transporte publico? - ?Mediante catenarias? - ?O una combinacion de ellas? Ya que eso, me definirá el tama?o de baterías ideal para mi flota de buses, aunque también se puede ver a la inversa: El tama?o de batería me ayuda a definir el método de carga mas adecuado.
Charging cycles, inflexibility in routes and change of schedules frequently (for eg a deployment scenario considering peak hours on business hubs vs. city shopping centers may not be as easy as reprogramming a bus number and route on any day) depending on the technology deployed (fast charging, ultra fast or swapping).
Na minha experiência com testes e contrata??o de veículos elétricos, dos vários desafios, quero citar um que é pouco discutido: Compreender quais linhas s?o passíveis de serem substituídas no sistema. Quando se fala em mudar a frota para elétrica e o estudo apresenta que várias linhas n?o s?o possíveis, por n motivos, é normal os gestores desistirem do processo. Entretanto, a tecnologia está em evolu??o, portanto, substituir as linhas que hoje já conseguem é importante. Pois já se inicia o processo de instala??o dos sistemas de carregamento e adapta??o das garagens para esse novo tipo de veículo.
Os desafios enfrentados pelos veículos elétricos no transporte público s?o inúmeros e impactam diretamente no custo e na satisfa??o dos passageiros. A necessidade de infraestrutura adequada para a recarga dos veículos, bem como a limita??o da autonomia das baterias, s?o fatores que elevam os custos operacionais e, consequentemente, o valor das tarifas. Além disso, a preocupa??o com a comodidade e a seguran?a dos passageiros também se faz presente, uma vez que a tecnologia ainda está em constante evolu??o. Diante desses desafios, é fundamental buscar solu??es inovadoras e sustentáveis para garantir a eficiência e a viabilidade dos veículos elétricos no transporte público.
First and foremost, to get the most benefit from electric buses and from any rail based systems, you need to be starting from a reasonably high baseline to begin with. There's little to be gained from having a poor market share to begin with and converting a diesel fleet to all-electric. This folly is compounded by removing bus lanes before you switch to electric buses. Yes, we need electric buses, but they need protected running routes first. Far better to build market share with BRT, or by dedicating to LRT to begin with, and then for these established BRT networks to switch to battery electric, than it is to have headline grabbing electric bus fleets with sub 10% mode share.
Despite the challenges, many public transit agencies around the world have successfully implemented or are planning to implement EVs in their systems. To achieve this goal, they should conduct feasibility studies and pilot projects to assess the technical, economic, and environmental viability of EVs in different routes and scenarios. Additionally, they should develop clear and realistic goals and strategies for EV deployment, such as setting emission reduction targets, selecting optimal vehicle types and sizes, and choosing suitable charging modes and locations. Engaging with stakeholders and partners is also necessary to ensure their support and collaboration in the EV transition. Moreover, public transit agencies should leverage funding and incentives to reduce the initial cost and risk of EV adoption. Finally, they should evaluate and improve the performance and impact of EVs using data collection, analysis, and feedback mechanisms to identify any issues or opportunities for improvement.

Peu ou pas d'entretien requis. Contrairement aux voitures à essence, qui nécessitent des vidanges et des mises au point régulières, les voitures électriques ne nécessitent qu’une recharge occasionnelle. De plus, comme les voitures électriques ne fonctionnent pas à l’essence, elles sont respectueuses de l’environnement.
Public transportation has increasingly adopted electric vehicles (EVs) in recent years. For instance, Shenzhen, China has electrified its entire fleet of more than 16,000 buses and 22,000 taxis, and installed over 20,000 charging stations. This program has reduced carbon dioxide emissions by 1.35 million tons and fuel consumption by 366,000 tons. Santiago, Chile has introduced over 800 electric buses, the largest fleet in Latin America, and plans to add more than 1,000 more by 2022. Oslo, Norway has replaced over 200 diesel buses with electric ones and installed over 1,300 charging points. These initiatives have saved $12 million in fuel costs in Santiago, and reduced nitrogen oxide emissions by 50 tons and noise levels by 15 decibels in Oslo. These examples demonstrate the potential of EVs for reducing emissions and improving public transportation.
As of October 2023, Santiago has more than 2,000 electric buses, which is just over 30% of its total fleet, with Chile being recognized as having the largest electric bus fleet outside China. Meanwhile, Delhi, India has introduced over 1,600 electric buses, just over 20% of its total fleet, as of February 2024. The government has also announced a plan to introduce “Mohalla buses” – small-sized e-buses to connect areas in outer Delhi to the main city, custom-designed for narrower roads.
Oslo has been a pioneer in electrifying its public transport, including buses, ferries, and trams, to achieve its goal of becoming a zero-emission city. The city's public transport agency has systematically replaced diesel buses with electric buses, reducing emissions and noise pollution. The electrification efforts extend beyond buses to include ferries and trams, contributing to Oslo's reputation as a leader in sustainable urban mobility.

An example i've seen through worldwide trend, everyone want introduce electric transportation. There are a lot of example of buses that already use EV as their main public transportation. Among company that already established their name in EV public transportation such as AVAS Matilda, Eurabas 2.0, BYD K-9, EPV Ecosmart, Gépébus Oreos 4X,
Let's not forget the power of e-bikes too! EVs can play a crucial role in public transportation, offering several benefits for both urban environments and the overall sustainability of transportation systems. However, e-bikes in public transportation adds another layer of flexibility and advantages, heres why: Reduced Congestion: EV's can still cause the age old problem of congestion. E-bikes can help alleviate traffic congestion by offering an alternative mode of transportation that is faster in dense urban areas, especially during peak hours. Last-Mile Connectivity: E-bikes provide an excellent solution for the "last mile" problem, helping commuters bridge the gap between public transportation stops and their final destinations.
Part 2. Second and most important point is the localization of chemical pollution makes it unattractive. Using diesel fuel does creat a global environmental agenda in the long run. Whereas the use of EVs with battery creates local environmental agenda. It shifts the CO2 global agenda to battery chemicals local pollutant agenda. Therefore, if public transport EVs use online (grid) electric energy sources (as the trolley buses), the benefit for the operators and the overall global environmental agenda could be high, otherwise EVs with batteries cannot be sustainable economically to operators and environmentally to local governors at least in the short run.
Drawing from my involvement and position in the deployment and execution of India's first electric bus project, I have gleaned several critical insights: 1. Effective route planning is paramount. 2. The planning of depots and charging stations is crucial. 3. Scheduling must accommodate timings for opportunity charging. 4. Maintenance facilities need to be properly equipped for the repair and maintenance of electric buses. For other modes like eTaxis etc i think charging station locations to cover entire city properly shall be critical.
The shift to electric vehicles (EVs) impacts road safety in various ways. EVs feature advanced safety technologies like automatic braking and lane-keeping assistance, potentially reducing accidents. Their design, with a lower center of gravity due to battery placement, improves stability and lowers rollover risks. However, the quietness of EVs poses risks to pedestrians and cyclists, leading to regulations for artificial noise at low speeds. Additionally, EVs' heavier weight due to batteries could increase collision severity. Despite challenges like emergency response to battery incidents, the transition to EVs is seen as a positive step towards safer roads, with ongoing adjustments needed to address new safety concerns.
I can remember when I was working for Charlotte Uptown Development Corporation (Charlotte Center City Partners), and we were making the needed assessment for shuttle services in the uptown Charlotte area for the first time. This was years ago before electric vehicles had really ever been used or were on ‘the scene’. We chose the initial option then because of fuel efficiency issues and true power efficiency trials, and a partnership at the time with electric providers from Tennessee and an interest locally with then-Duke Power. It was a successful choice to service a small route in the uptown area, to try alternative energy sources and test both market and supply options. That was truly almost 30 years ago, way ahead of many EV choices.
