A budget without layoffs or service cuts narrowly received Santa Maria Town Hall‘s approval this week amid a dispute over the provision of Spanish translation services during meetings.

Mayor Alice Patino along with council members Etta Waterfield and Mike Cordero voted to pass the budget, but their colleagues Gloria Soto and Carlos Escobedo voted against.

The dispute arose after City Manager Jason Stilwell offered options for translation services ranging from the status quo, with live interpreters working during meetings upon prior request, to the city paying for an interpreter to attend all meetings of the advice.

“The threshold question is whether the board wants to do something different, and then how much,” Stilwell said.

A moderate option would be to initiate closed captions in Spanish for Youtube meeting recordings.

Language interpreters translate orally (sometimes in a real-time setting, such as government meetings or court hearings), while the term translator generally refers to someone who translates written material from one language to another. The terms are sometimes used interchangeably for translation services.

About 65% of residents in the city of Santa Maria speak a language other than English at home, according to data from the US Census Bureau.

Soto and Escobedo supported hiring Spanish-language interpreters, with Escobedo suggesting a one-year trial period to gauge demand for the service.

“I just can’t stress the importance of accessibility for all residents when it comes to local government so that we can ensure genuine and genuine engagement,” Soto said. “I would say we’re going to do the whole thing. Let’s bring someone.

“I disagree,” Waterfield said, adding that the $200,000 cost could be used for other programs, and pushed for a conservative approach.

City staff provided an estimate of $200,000 for the service based on Santa Barbara County costs. However, county meetings are often all day long and include two locations (in the courtrooms of the Santa Barbara and Santa Maria administration buildings), so they may not be valid for Santa’s anticipated expenses. Mary.

Stilwell said the city has in the past paid $60 an hour for a two-hour minimum for translators, which would make the cost much lower than the county.

Waterfield, Patino and Cordero voted to add Spanish closed captions to YouTube video replays of council meetings in addition to continuing to provide translators at city council meetings upon prior request. They also asked staff to contact Spanish-language media to share information about the services offered.

“If the need is there, then I agree 100% we should have someone here to do it,” Cordero said. He added that translation services should not be limited to Spanish, but include Mixtec and other locally spoken languages ​​as needed.

“I think some people have to take responsibility too. We cannot take full responsibility for that,” Patino said.

“I think we have to keep in mind that this is taxpayers’ money and we have a lot of unfunded things that we need to do in Santa Maria,” Patino added. “I think we have to be wise in how we spend taxpayers’ money.”

“In my 19 years with the city, I don’t recall a single employee or meeting rejecting people or making anyone feel very unwelcome,” Waterfield said.

Escobedo said council should consider how to accommodate members of the Spanish-speaking community in guest rooms.

“At least let’s try for a year…” said Escobedo, for whom Spanish is the first language. “Let’s find common ground. Let’s go, let people know and then we can move on. That would be my two cents.

“I have no idea what you said,” Waterfield said with a laugh. “I’m just trying to understand.”

Soto expressed his disappointment with some comments from his colleagues during the discussion

“The others, it’s terrible to be completely frank. It’s important for us to remember that the Spanish-speaking monolingual community is also part of our taxpayer base,” Soto said, adding that having translators would remove a barrier.

The Santa Maria Mixed High School and Santa Maria Bonita school districts routinely provide Spanish language interpretation services at their board meetings.

The City’s biennial financial plan, available herecovers the financial years 2022-2023 and 2023-2024.

For the next fiscal year, beginning July 1, appropriations for all funds will be $333.5 million, including $119.4 million for the general fund.

The budget proposed the addition of 36 full-time positions and five part-time positions, including six in the police department and two in the fire department.

The city plans to restore the hours of operation of the Santa Maria Public Library on Sundays and extend the hours of operation of the bookmobile in the second year.

The budget also includes $22.8 million over two years to upgrade the Santa Maria Regional Transit fleet, primarily to add electric buses.

A second aerial ladder truck, at a cost of $1 million, is proposed for the fire department.

Other changes include moving the code enforcement division from the city attorney’s office to the community development department.

The budget also proposed 151 capital projects at $140.7 million. However, several dozen proposed projects will not be funded.

“Overall, this is a balanced budget that maintains and improves public services. We can be proud of this two-year spending plan for what it will do in our community,” Stilwell said.

Rep. Lauren Boebert (R-CO) has repeatedly insulted Transportation Secretary Pete Buttigieg and her husband, Chasten. She voted against President Joe Biden’s infrastructure initiative and decried it as wasteful spending.

Now, however, she goes hat in hand to Buttigieg, asking $33 million for a new bridge in his neighborhood.

Related: Right-Wing Rag Attacks Pete & Chasten Buttigieg With ‘Poem’ Full Of Homophobic Tropes

Boebert proudly proclaimed last year that she gave birth in a truck in order to insult Transportation Secretary Pete Buttigieg for taking “maternity leave” to “find out how to feed” her children. She said he wasn’t doing his job and accused him of making an “R-rated” movie with Jeff Bezos instead.

But now she would like a bridge to drive her truck over.

“With funds from the Rural Surface Transportation Grant, Glenwood Springs will construct a new bridge connection that will provide a second emergency route/critical evacuation access between State Highway 82 and the west side of the Roaring River. Fork in the city’s southern corridor,” she said. wrote in a letter to Buttigieg. Wildfires have ravaged Colorado in recent years due to climate change, which Boebert downplayed as a liberal plot to raise gas prices.

But only a few months ago, Boebert called the spending “wasteful” and said only “RINOs” (Republicans in name only) would support the initiative. When the Herald of Durango asked the far-right MP about the hypocrisy of asking for money from a fund she opposes, Boebert turned away from the question.

“I’m all for investing in rural Colorado, but Biden’s so-called infrastructure bill was the wrong way to do it,” she told the newspaper. “Less than 10% of (the) $1.2 trillion infrastructure bill went to roads and bridges. The bill provides tens of billions of dollars for Solyndra-style slush funds, the policies of Green New Deal, electric buses (sic) and government welfare.

This isn’t the first time Boebert has tried to quietly ride Buttigieg’s coattails to a stronger approval rating. The initiative to improve the country’s aging infrastructure has been incredibly popular among average Americans.

She distributed a newsletter that touted “9 Boerbert wins for Colorado” earlier this year. She bragged that she brought needed money to local communities, but the money came from the infrastructure package and earmarkings. Earmarks, specific funding priorities added to legislation before final passage, were also the target of Boebert’s contempt. She says she opposes it.

Buttigieg, a professional administrator, should ignore Boerbert’s partisan and personal attacks when considering the application.

Hungary and Egypt will continue their transport cooperation and explore the expansion of military-industrial cooperation, László Palkovics, Minister of Technology and Industry, said after talks in Cairo on Monday.

Palkovics and Kamel al-Wazir, Egypt’s transport minister, agreed on the growing importance of railways and electrified rail infrastructure powered by solar panels, as well as the potential involvement of Hungarian companies in related projects. Hungary could also deliver electric buses to Egypt, he added.

Hungary is involved in the delivery of 1,300 railway wagons to Egypt, and other opportunities may arise for Hungary in the North African country, Palkovics told MTI by telephone.

Palkovics noted that tourism was a key source of income for Egypt, adding that both countries had an interest in Wizz Air launching new flights to Egypt, and he asked his Egyptian partner to eliminate the administrative and financial obstacles to the expansion of the Hungarian low-cost airline.

The Minister also highlighted new areas of bilateral military-industrial cooperation. Hungary and Egypt will soon continue to discuss these opportunities, as the Egyptian minister in charge of military production is due to visit Hungary in the coming months, Palkovics said.

Besides the transport minister, Palkovics met with Mohamed Ahmed Morsi, minister in charge of military production, Mohamed Manar Anba, minister of civil aviation, and Abdelmonem Eltarras, president of the Arab Organization for Industrialization.

Egyptian President Abdel Fattah el-Sissi visited Hungary in 2021 and held talks with Prime Minister Orbán.

Tribune press service

Chandigarh, June 18

The Chandigarh Transport Undertaking (CTU) has decided to lease 20 AC diesel buses for intercity operations on a km basis.

Unable to get an answer twice earlier, the ministry went out to tender for the third time. On the other hand, the CTU workers’ union opposed the department’s decision to lease buses under the km program. Previously, 40 electric buses circulating in the city were leased under the program and the department will receive 40 more electric buses by next month.

A department official said the main objective was to motivate people to prefer the use of public transport as a means of travel to personal transport by modernizing the fleet and operations and improving the quality and appearance of buses in order to they are comfortable, aesthetic. and attractive.

It will be the responsibility of the selected company to keep the buses in working order and clean. These buses will be leased by km for 10 years, which can be extended by one year depending on the condition of the buses.

In the 20 diesel buses, the driver will be hired by the company, while the driver will be from CTU. The agency must deliver the buses within 90 days of issuing the letter of award. Interested agencies can submit their proposals before July 12 and the call for tenders will open the same day.

The new buses will be equipped with air conditioning and heating installations. Additionally, the forward destination map will be LED-based. Each bus will have nearly 47 seats. CCTV cameras will also have to be installed on the buses.

With recent announcements from state governments such as Victoria to transition to electric bus fleets, many businesses are now operating with a mix of hydrogen and electric buses. ABC takes a look at the difference between the two.








Volvo questions whether hydrogen or electric is better for the future of buses

The bus industry is leading the way in many ways as the world shifts to greener modes of transportation.

This should come as no surprise to those working in the industry – buses often run in city centres, around pedestrians and outdoor dining areas, so fleets’ rapid transition to zero emissions will help governments clean up towns.

A number of governments are choosing to go electric, but many fleets are also using hydrogen, so which is best?

ENERGY STORAGE

A hydrogen engine works the same way as an electric bus, but it’s in the way the energy is stored and harnessed that the two differ.

Hydrogen is a clear gas that can be harnessed in many ways including using fossil fuels, but when produced using renewables it is a green energy source .

Once produced, it can be transported in the same way as gasoline and pumped into the tanks of the bus to then be converted into electrical energy in a fuel cell.

This is where the two types become similar – the energy is then either used to power the bus or stored in a battery for later use.

An electric bus stores energy from a power source such as renewable energy or mains power in a battery which powers the driveline.

Both types of buses have similar powertrains or an “electric motor” that powers the vehicle.

SETTING UP

The transition of bus operators to a greener fleet requires a drastic change in infrastructure within depots.

Where a driver has traditionally left a depot to refuel at a service station, now much of the refueling will be done on site, either by hydrogen pumps or battery charging.

Mark Fryer, head of Volvo National Engineering and Bodybuild, explains some of the challenges companies face when switching to renewable energy.

“Hydrogen requires a higher installed cost for infrastructure due to the nature of the gas,” says Fryer.

“There are many additional safety standards and requirements that must be met for this solution to be used in the depot. Plus, a lot of operator training because this solution is so foreign to most.”

The electric solution requires a battery charger to complete the configuration. There is also a certain number of kilowatts needed to charge all the vehicles that must be taken into account, the question being whether the network is sufficiently supplied?

“How can we best use solar power to charge vehicles? Does the depot need storage batteries? These are all questions operators need to ask themselves,” says Fryer.

For operators on long-haul routes such as Melbourne to Canberra, there are a number of considerations they need to take into account when considering a move to an eco-friendly bus fleet.

A recent announcement from the state governments of Queensland, New South Wales and the State of Victoria may provide a solution to this problem.

In March, the governments of the three states announced a historic memorandum of understanding to install a hydrogen fueling network along the eastern seaboard.

Dr Fiona Simon, CEO of the Australian Hydrogen Council (AHC), said the announcement was an exciting time for the AHC.

“Collaboration between these three states will facilitate the adoption and use of hydrogen as a fuel for heavy transportation along the eastern highways,” she said.

Although recharging an electric bus can cause a lot of downtime, especially on a long trip, the grid or hydrogen pumps along the east coast can solve this problem.

The challenge operators face is the range of each vehicle, as more time spent loading and not transporting customers will increase costs.

Mark Fryer explains some of the challenges that each form of renewable energy poses to those considering using them.

“Hydrogen allows you to carry more usable energy than an electric but, in electric, 25% of the energy is wasted whereas, in hydrogen, 75% of the energy is wasted,” he says. he.

ELECTRIC ATTRACTION

It looks like state governments are looking to electric buses for city center bus lines with a number of recent announcements demonstrating where governments are looking at the future of buses for city center lines.

The Victorian Government will deploy 41 buses across five different networks across the state to help Victoria reach its goal of net zero emissions by 2050 in a landmark trial.

Public Transport Minister Ben Carroll spoke of the importance of rolling out electric buses.

“Trialing the electric bus will be instrumental in our transition to a more environmentally friendly and sustainable transport network.

“Creating a greener fleet is part of our bus plan to develop a more modern and reliable network that will attract more people to the convenience of buses,” Carroll said.

The Queensland Government recently opened the first all-electric bus depot on the Gold Coast, with 100% of the energy used to charge the buses coming from renewable sources.

Using solar panels in depots appears to be an effective way to make fleets as green as possible.

Electric bus fleets are essential for governments aiming to achieve zero or net zero emissions goals.

Queensland State Government Minister for Transport and Trunk Roads Mark Bailey said he was building on the state government’s recently released zero-emission vehicle strategy.

“We are committed to having every new bus in South East Queensland be zero emissions from 2025, so to see it happening now is a fantastic achievement,” Bailey said.

Mark Fryer explains that, for operators, it is not a simple either/or decision, but something where they have to establish the needs of the business.

“I think each operator will have to make their choice based on their local factors, including the power available to charge the batteries, the cost of the infrastructure, and the route requirements, including range,” he said. he declares.

For Volvo, when helping a customer choose the option that’s best for them, they take a hands-on approach.

“It’s always the customer’s choice, but we can do full simulations on the route to make sure the electric product is suitable for that route,” says Fryer.

“We also have the flexibility to increase or decrease the number of batteries for the customer to ensure their route requests can be met.”

While the shift to renewable energy on the roads is an exciting time for the industry, it presents a number of challenges and the years to come will be important for the survival of these energy sources.

Victoria’s first all-electric bus depot will charge 27 buses in Melbourne’s north by the start of 2024 as part of Andrews Labor Government’s zero-emission bus trial.

The largest participant in the $20 million trial, bus operator Ventura, will install 15 charging stations to power electric buses at its converted Ivanhoe depot, with its first 12 test electric buses set to enter the network This year.

In early 2024, the depot’s 27 electric buses will run on nine routes through the northern suburbs, transporting up to 10,000 people each week, including to La Trobe University and Northland Shopping Centre. They will travel more than 1.2 million kilometers over a year.

Major work to convert the depot to an all-electric depot will involve the construction of a new on-site substation and the installation of battery management technology and charging units, with work due to start in early July and end in November this year.

The initiative will provide valuable insight into the challenges and issues of transitioning an entire bus depot to battery electric bus technology, before more depots are built or converted in the years to come.

Six Victorian bus companies have been selected to trial two hydrogen and 50 electric buses on existing routes in Melbourne, Seymour and Traralgon, fostering vital partnerships between bus operators, manufacturers and energy companies ahead of the major transition from the state away from diesel buses.

Achieving zero emissions for buses is essential for Victoria to meet its legal commitment to net zero emissions by 2050, with the Labor government pledging that all new buses from 2025 will be zero emissions. A phased approach will allow the industry to prepare for the transition of around 4,000 buses to zero emissions.

Creating a greener fleet is part of Victoria Bus Map develop a more popular, modern and reliable network.

As Public Transport Minister Ben Carroll said

“We have a lot of work ahead of us as we transition our bus fleet to zero emissions, so having the opportunity to study and learn from the conversion of the Ventura depot to an all-electric bus depot will be invaluable for this process.”

“We are moving from dirty diesel to fume-free buses in an orderly and informed way that brings bus operators, manufacturers and energy providers on our side. »

As Minister of Energy, Environment and Climate Change Lily D’Ambrosio said

“Transport is the second biggest contributor to Victoria’s emissions – we are investing in putting more zero-emission vehicles on the road for personal and public transport, helping to cut the cost of living while halving emissions by 2030.”

As Ivanhoe MP Anthony Carbines said

“Zero-emission vehicles are the way of the future, so it’s very exciting to see Ivanhoe as the location for this game-changing new depot.”

As Ventura General Manager Andrew Cornwall said

The transition from diesel buses to locally built electric buses at our Ivanhoe depot will be a breath of fresh air for customers traveling to destinations such as Latrobe University, Northland Shopping Centre, Preston Market and Railway Station of Gowrie.

“This trial will pave the way for us to have confidence in purchasing the right equipment to outfit our remaining 11 depots in time for the transition to all new zero-emission buses from 2025.”

Background

The global energy structure is gradually changing as energy constraints and pollution problems increase. Due to their low emissions and excellent fuel efficiency, electric vehicles are gaining popularity. Electric buses possess more advantages in the public transport system than ordinary diesel buses.

However, several issues remain, such as challenges in assessing charging needs, planning vehicle routes, and designing battery energy storage systems. Therefore, the development of an accurate vehicle energy consumption prediction model can solve the aforementioned problems that are critical for the widespread adoption of electric buses.

China’s National New Energy Vehicle Monitoring and Administration Platform (NEVS) has collected vast amounts of data on new energy vehicles. For vehicle energy consumption research and modeling, the platform can provide a large volume of vehicle driving data. Previous studies have used physical modeling approaches or artificial intelligence algorithms to develop vehicle energy consumption models. The results of a single type of model or a single method of estimating energy consumption are less reliable. A more reliable energy consumption estimation model with few input features is required.

About the study

In this study, the authors discussed the development of a physical and data-driven fusion model for estimating the energy consumption of electric buses. A simplified physical model was used to model the basic energy consumption of the electric bus. The model took into account the effects of brake use, rolling drag and air conditioning consumption. A CatBoost decision tree model was built to account for volatility in power consumption caused by many causes. After that, a fusion model was created.

The team tested the performance of the energy consumption model using electric bus data analyzed on a big data platform. A physical and data-driven fusion model has been proposed for vehicle energy consumption. Physical formulas have been used to express some of the energy used by the vehicle while driving, such as the energy used by rolling resistance and air resistance. Model complexity has been reduced by using formula modeling directly.

The researchers statistically analyzed the data from the electric buses. To acquire continuous data in the car’s charging and driving cycle process, the original data was pre-processed and recreated. The energy consumption estimation model was also created. Based on the dynamic performance of the electric bus powertrain, a physical model of vehicle power consumption was constructed.

The least squares method was used to calibrate the model parameters first. In addition, elements that influence changes in vehicle energy consumption, such as driving habits and environmental factors, were summarized and discussed. The impacts were described using the CatBoost decision tree model, and finally, the two models were combined to obtain the final result of the vehicle energy consumption estimate. The energy consumption estimation model was reviewed and validated.

(a–h) Relationships between speed variation, average speed, number of accelerator pedal presses, number of deceleration pedal presses, departure time, departure date , ambient temperature, battery internal resistance and power consumption, respectively.

Comments

The time taken to process the data was six seconds, while the time spent training the model was only 0.9 seconds. The results revealed that for many vehicles, the errors in estimating energy consumption were less than 8.1%. The results of the estimation of vehicle energy consumption had an average inaccuracy of 7.5%. On the Bus 1 dataset, the relative error of the fusion model was 4.8%.

The proposed model had a high level of accuracy, with an average relative error of 6.1%. The fusion model has been a useful tool for vehicle planning, optimizing the energy consumption of electric buses and the rational organization of charging stations. Other driving factors, such as vehicle departure time, ambient temperature, etc., impacted the vehicle’s driving energy consumption. The correlation coefficient was 0.79. With both indicators, the fusion model outperformed conventional energy consumption modeling methods. The proposed merger model was used as the basis for vehicle planning, optimization of the energy consumption of electric buses and the layout of charging stations. The majority of points with substantial inaccuracies were concentrated in severe weather.

conclusion

In conclusion, this study estimated the energy consumption of electric buses using a data-based and physical fusion model. A rudimentary model of energy consumption was built in terms of physical modeling. The effects of kinetic energy consumption, rolling drag and air conditioning have all been considered. The main factors determining the variability of vehicle energy consumption were investigated using data-driven modelling. The model input features have been simplified so that the model input can be built before the car is driven. The variable power consumption assessment model was built using the CatBoost decision tree modeling approach. The concept of built-in learning was used to optimize the model in a hierarchical iteration during the model training process.

The average relative imprecision of the vehicle energy consumption estimation result was 6.1%. Also, during the driving process, the mass of the vehicle was treated as a constant value, which contributed to the model error. The authors mentioned that meteorological parameters could be added to the model in the future to further improve its accuracy.

The central government has asked states to replace thousands of aging diesel public buses with electric ones, but state transport units say their finances have collapsed because passenger numbers have fallen after the pandemic.

The Ministry of Road Transport and Highways (MoRTH) has instructed State Transport Units (STUs), responsible for procuring and operating buses, to replace over 32,000 old diesel buses with vehicles electric, said several people familiar with the development.

Twenty-five STUs, according to an estimate by MoRTH, own 32,062 buses that are more than 10 years old. According to a draft notice from MoRTH, permits for buses at the end of their 15-year life cycle will not be renewed, meaning they will have to be phased out.

Granted, some states, like Delhi, already have rules in place on scrapping old vehicles.

Most of the aging buses currently in use by STUs, with the exception of Delhi which has an all-CNG fleet, are BS-II or BS-III diesel buses which are not only highly polluting but also expensive to maintain and to exploit.

But STUs were badly hit by low usage in the aftermath of the covid-19 pandemic, when intra- and inter-city public transport was hit hard as commuters switched to personal mobility.

VC Sajjanar, Vice President and General Manager of Telangana State Road Transportation Corp., said: “Switching to electric buses is a good plan, but STUs have been in bad shape after covid-19. We are losing 4 to 6 crore per day due to increased operating costs as diesel prices have steadily increased. Electric buses will help reduce costs. We have nearly 2,000 buses nearing the end of their life and needing to be scrapped, but we cannot fund these orders when we incur losses – our operating costs are currently close to 20 crore, we only do about 12 crore or more. Even on a peak day with more than 70% utilization, we do 4 to 6 crore losses,” he said.

“We are asking MoRTH to participate and assist STUs through grants and sustainability gap funding. We will have to invest in setting up charging infrastructure and we can use government assistance here,” Sajjanar added.

Telangana recently placed an order for 300 electric buses through a tender launched by Convergence Energy Services Ltd (CESL), a public sector unit, to aggregate demand for electric buses by taking advantage of the incentive scheme restructured FAME-II.

CESL’s tender resulted in the discovery of prices for electric buses that were found to be less than or equal to the operating costs of diesel buses, prompting NITI Aayog to commission CESL to extend the exercise to a national level for 50,000 electric buses.

“STU is indeed keen on scrapping these old buses – they are inefficient and polluting. But we also need to keep STU’s finances in mind. Now that we know the prices are lower than diesel I am sure we can devise a proper mechanism to help them,” said Mahua Acharya, CEO of CESL.

A senior MoRTH official said: “The draft Disposal Notification has not yet been finalized given the financial constraints of STUs. But it is certain that they will have to replace the old and inefficient buses.”

Guwahati: Diesel-powered buses will be banned in Guwahati soon after the state government launches 200 electric buses, which have already been tendered.
Transport Minister Chandra Mohan Patowary told media on Saturday that CNG would be an available option for private bus owners. “We have prepared a pollution control policy. In the first phase, we launched 20 electric buses in Guwahati. The Assam government will then purchase 200 such buses after which diesel buses will no longer be allowed to operate in Guwahati city,” Patowary said.
He cited population growth in the city and increased pollution as the reason diesel-powered buses were taken off the road. “They will no longer be able to run buses on petrol or diesel. If they want to continue with these vehicles, they will have to convert them to CNG buses. In phases, we have prepared a roadmap to operate electric buses across the state,” Patowary added.
He said various electric vehicle manufacturers were approaching the state government.
Meanwhile, the association of bus owners reacted strongly, criticizing the “unilateral decision”. Pradip Das, general secretary of the All Assam Motor Transport Association, the umbrella organization of commercial vehicle owners associations in the state, denounced the hasty decision.
“About 1,000 diesel city buses are operational in Guwahati, including those of the government-owned Assam State Transport Corporation. If all the diesel-powered buses go off the road, how will the 200 buses meet the needs of the city?” He asked.
Das, however, said carriers have no objection to converting buses to CNG for better mileage in a phased manner. “The Covid-19 pandemic has hit the transport sector hard. For the conversion to CNG, we will need government assistance as it is an expensive affair,” he added.
In September last year, the government of Assam announced plans to convert existing public transport and government vehicles to electric mode by 2030 under a new policy – Electric Vehicle Policy of Assam, 2021. It has also set a target to introduce at least two lakh electric vehicles in the next five years through a package of incentives for buyers.
