With the acceleration of urbanization and the continuous growth of urban population, the pressure of urban transportation is gradually increasing, and the urban traffic situation is complicated, and its safety problems are increasingly apparent. The Research Progress of Urban Traffic Meteorological Observation and Early Warning and Forecasting Technology, which was jointly compiled by Jiangsu Meteorological Bureau and China Institute of Meteorological Science, made research and exploration on observation means and methods, interpretation of numerical model prediction and application of artificial intelligence technology, and provided a positive solution for urban traffic safety management.

In recent years, Jiangsu Meteorological Bureau has gradually launched the brand of "Traffic Meteorological Service" in the whole country on the basis of traffic meteorological research and service iterative upgrade, combined with the pilot work of early warning and disposal of bad weather traffic and the work results of 108 national optimization and upgrading projects of bad weather and high-impact road sections. Meteorological researchers used the self-developed comprehensive experimental platform for highway traffic meteorology, traffic meteorological warning control piles, intelligent video recognition software and hardware integrated machine and other related instruments and equipment to conduct thermal spectrum map observation experiments on expressways in Jiangsu Province and highways around Nanjing, Huai ‘an and other cities, providing data support for studying pavement temperature distribution characteristics, road maintenance operations and driving safety under high and low temperature weather, and helping to realize comprehensive monitoring and dynamic management of urban road networks.

"Meteorological conditions are one of the key factors affecting urban traffic." Dr. Zhu Shoupeng, the first author of the research progress and the traffic meteorological team of Nanjing Institute of Meteorological Science and Technology Innovation, introduced that on the one hand, bad weather such as heavy snow and cold wave can easily lead to road icing and road breakage, which will affect the normal operation of the urban transportation system; On the other hand, different meteorological conditions such as fog (mass fog) and precipitation will also affect the driver’s visual function, reaction ability and driving ability, thus affecting traffic safety. The traffic meteorological team combed around the establishment of observation network, the development of observation experiments, forecasting and early warning technology, meteorological business services and other aspects, and discussed the frontier dynamics and development trends in the field of urban traffic meteorology at home and abroad.

Under the background of global warming and frequent extreme weather, severe weather such as dense fog, heavy precipitation, extreme high temperature and low temperature is becoming more and more frequent, and the impact of severe weather on urban traffic can not be underestimated. At present, meteorological departments all over the world are carrying out traffic meteorological research in succession to promote the development of traffic meteorological observation, early warning and forecasting and other related technologies. "Strengthening the monitoring of urban traffic meteorological disasters and improving the ability of early warning and forecasting are important foundations for helping the construction of smart cities and transportation powers." Zhu Shoupeng said that this is also the direct driving force for the team to carry out research. The traffic meteorological team further strengthened the technical research, and developed a variety of short-term and imminent forecast and early warning technologies of dense fog based on multi-source observation data and machine learning, intelligent monitoring and early warning technology of road surface condition based on deep network model, and forecast and early warning technologies of road surface temperature and road surface condition, and optimized them according to the special conditions of specific scenes, which have been successfully applied to the dynamic early warning and intelligent decision support system of meteorological disasters of Mazhao Expressway in Yunnan Province, and achieved remarkable social and economic benefits.

With the rapid development of big data and artificial intelligence, Jiangsu Meteorological Bureau has also turned its attention to all kinds of more advanced technical means, and made simultaneous efforts in observation means, forecasting mode, key technologies and working mechanism, further carried out research and service work on traffic meteorology, urban meteorology and urban traffic meteorology, promoted the development of relevant theoretical research and forecasting technology, and provided a solid scientific and theoretical basis for building a higher-level traffic power, smart city and disaster prevention and reduction.

In today’s automobile market, BYD Han has become a magic car in the hearts of ordinary consumers with its excellent performance, people-friendly price and economical use cost. Today, taking BYD Han as an example, starting from the data of insurance premium, charging fee, maintenance fee, etc., we analyze in detail why it can become the best choice for ordinary people.

I. Insurance premium: affordable and fully guaranteed.

For ordinary consumers, the insurance premium after buying a car is an expense that cannot be ignored. However, BYD Han has shown a very high cost performance in terms of insurance premiums. The insurance cost of my new BYD car in the first year is about 7000 yuan. This price is obviously more close to the people than the luxury models of the same level.

Take the 2022 BYD dmi Premium Edition as an example. Its annual premium includes compulsory insurance in 760 yuan, travel tax in 0 yuan and commercial insurance of 2,894.72 yuan, totaling 3,654.72 yuan. With the accumulation of driving records, the premium will decrease year by year. Such insurance premium is undoubtedly an acceptable expense for ordinary consumers.

Second, the charging fee: low cost, green travel

In the field of new energy vehicles, charging fee is one of the most concerned issues for consumers. As a pure electric vehicle, BYD Han has shown a very low cost in charging fees. Take the 2022 BYD Han dmi Premium Edition as an example, its power consumption per 100 kilometers is 13.2kWh. If you drive 20 thousand kilometers a year, the electricity bill is about 1700 yuan. This cost is much lower than that of similar fuel vehicles, which saves consumers a lot of fuel expenses.

In addition, BYD Han also supports various charging methods such as household charging piles and public charging piles, which provides great convenience for consumers. When charging public charging piles, although the cost will be relatively high, considering the battery life and the convenience of charging, this cost is still reasonable.

Third, the maintenance fee: economical, quality assurance.

In terms of vehicle maintenance, BYD Han also showed the characteristics of economic benefits. Take the 2022 BYD Han dmi Premium Edition as an example, its maintenance is relatively simple, and it needs about 300 yuan every time. This fee includes the inspection and replacement of the status of the three power systems, air conditioning filter elements, brake fluid and antifreeze. Compared with the same level of fuel vehicles, BYD Han’s maintenance costs are obviously more close to the people.

In addition, BYD Han’s maintenance cycle is relatively long. Take the 2022 dmi distinguished model as an example, the first maintenance is carried out within 5,000 kilometers or 3 months, and then the routine maintenance is carried out every 20,000 kilometers or every 12 months. Such a maintenance cycle is undoubtedly more friendly to ordinary consumers. At the same time, BYD manufacturers may also provide some maintenance preferential policies, such as free first insurance, maintenance packages, etc., which further reduces the maintenance cost of car owners.

Therefore, BYD Han is more cost-effective.

Recently, a Changan Mazda EZ-6 car purchase invoice has triggered heated discussions on the auto forum. The invoice shows that the purchased model is an EZ-6 pure electric BEV model, priced at 221,800 yuan. Many people believe that as Changan Mazda’s first new energy product, this certain price is reasonable and competitive for a joint venture B-class car market that only provides range extension power. This adds a strong touch to Changan Mazda’s important step into the new energy market.

Let’s first verify the authenticity of this invoice. According to the pictures released, the invoice date of this car purchase invoice is August 16, which is more than a month earlier than the pre-sale time. This time difference is not surprising for car companies. Car companies usually have a complete time advancement process before a new car is launched, especially in joint venture car companies, decision-making requires the joint participation of both China and Japan. Therefore, it is understandable to agree on the price two months in advance. In addition, although the key code and other information on the invoice are coded, from the information of the invoice, the information of the invoicing party and the details such as the invoice seal of Changan Mazda Automobile Co., Ltd., can almost confirm the authenticity of this invoice. This also means that the price of 221,800 yuan shown in the invoice is likely to be the actual price of the EZ-6.

In fact, since the EZ-6 made its debut at the 2024 Beijing Auto Show, it has quickly become the hottest sedan in the joint venture new energy field. From the perspective of vehicle design, the EZ-6 stands at the forefront of joint venture new energy design. It is the only model in the joint venture B-class sedan market that offers extended range power options, filling the gap in the joint venture new energy extended range products in the market. This uniqueness makes the EZ-6 quickly attract widespread attention both inside and outside the industry.

In terms of specifications, the product power of the EZ-6 should not be underestimated. In terms of body size, the length, width and height of the EZ-6 are 4921mm, 1890mm and 1485mm respectively, and the wheelbase is 2895mm. It adopts a frameless door and a hatchback design. Although it is more new energy, the through taillights and four round gun downlights on both sides still retain the classic design elements of Mazda.

In terms of power, the EZ-6 is available in both pure electric and extended range forms, and adopts a rear-drive layout. The power parameters of the pure electric version are 190kW, while the extended range version uses the same 1.5-liter range extender, and the power parameters are exactly the same. In terms of battery life, depending on the capacity of the battery pack, the pure electric model can last between 480km and 600km, while the extended range vehicle can achieve a long battery life of more than 1300km with a single charge and a tank of fuel.

In terms of intelligent configuration, the EZ-6 is also leading the way. It is equipped with the Qualcomm Snapdragon third-generation 8155 chip, equipped with a 14.6-inch floating center control screen and a full LCD instrument cluster. In addition, there are high-tech configurations such as AR-HUD head-up display, 180-degree panoramic chassis, etc. Adaptive cruise control, lane keeping assistance, automatic parking and a rare Sony sound system of the same level, as well as 64-color ambient lights, zero-gravity seats, etc., further enhance the sense of technology and luxury of the whole vehicle.

In terms of product power and price, the price of 221,800 yuan is very competitive for the EZ-6. Compared with the same level of models, such as Tesla’s price is close to 300,000 yuan, and the price is also about 300,000. The starting price of the Volkswagen ID7 is 227,700 yuan. The pricing of the EZ-6 is undoubtedly very reasonable and very attractive. Especially its extended range version can greatly relieve users’ "battery life anxiety", which is also its unique market advantage.

Combined with Mazda’s past pricing strategy, it is expected that the final price of the EZ-6 may fall between 180,000 and 240,000. If the pre-sale period is matched with some preferential policies, such as car purchase subsidies and low-interest loans, it will undoubtedly bring huge pressure to the existing joint venture new energy model market.

According to the latest news, the EZ-6 will start pre-sale on September 28th and is scheduled to be officially launched at the end of October. As the pre-sale and launch date approaches, more details and official pricing will be revealed.

The upcoming launch of the Changan Mazda EZ-6 signals a strong competitor in the field of new energy. Can the EZ-6 make waves in the market and trigger a consumer car buying boom? Let’s wait and see. Readers are welcome to share their views and expectations for this car in the comment area.
