Undoubtedly, the new format of the Internet era, such as the car, allows more people to experience the convenience, economy and pleasure of travel. However, in major cities such as Beijing, although strict restrictions on purchases and purchases have been taken for private cars, the degree of traffic congestion has intensified with the rapid development of online cars in the past year or two. No matter what kind of ground transportation is adopted, its travel experience Both are greatly discounted. Industrial plug valves are wildly used in oil tank or any type of chemical industry pipeline system. DBB Plug Valve and Sleeved Plug Valve with ASME & DIN standard are commonly used by customer. Industrial Plug Valve are with soft and metal seal type and valve size are from 1/2 inch to 24 inch(DN15-DN600) matching pressure from class 150 to class 600(PN10-PN100) which are suitable for operating in the working media temperature from -29℃ to 180℃, as well as material in carbon steel, stainless steel, alloy steel and duplex steel in casting material.

A sustainable urban transport system should enable efficient movement of people and things, not the movement of cars. Under the condition that the city is in a contradiction between supply and demand and traffic congestion, as the manager of the urban transportation system, the various modes of travel should be prioritized based on the comprehensive effects of efficiency and consumption. High-efficiency and low-cost travel is better than low-efficiency and high-traffic travel, and should be given a high priority to encourage travel. Specifically, urban sustainable development should give priority to public transportation and non-motorized transportation. This is also the fundamental purpose of traffic demand management in many cities such as Singapore, Hong Kong, London, Tokyo, New York, Beijing, Shanghai, etc., which have restrictions on purchases, restrictions, congestion charges, and high parking fees. The core idea of ​​these managements is to increase the cost of owning or traveling by individual cars, and to promote large-capacity public transportation and green travel such as bicycles and walking.
Since the rise of the network about car rental, it has been regarded as a representative of the sharing economy. The so-called shared economy refers to the economic model in which each person contributes his or her idle resources (tangible assets, intangible services, time, etc.) to others and obtains corresponding returns. However, if it is only to achieve efficient and low-cost use of private low-capacity vehicle resources, rather than the efficient use of public road resources, it will eventually lead to inefficiency in the use and operation of the entire transportation system resources.
In fact, in addition to walking, people's travel depends on transportation infrastructure and carrying tools, both of which are indispensable. Regardless of the network car or the cruise car, the realization of its basic functions requires the use of road resources to transport passengers. The network about car rental improves the utilization efficiency of idle vehicle resources and enhances the availability of vehicle resources, but it also increases the road traffic and mileage. The road resources are fixed resources and cannot be reserved through Internet. When the resource is air conditioned, or increase its capacity. Therefore, the excessive use of the network car will undoubtedly increase the load of limited road resources, especially the peak load. The peak hours of the Beijing road network are already in an overload state. The traffic flow in many sections is super-saturated traffic flow, which has significant fragility and low reliability. Adding a small number of car trips will cause the operation of the road network. The larger impact, so like private cars, the government should adopt a more strict control strategy for the number of vehicles or cruisers to ensure that the city has a sustainable travel structure.
In addition, whether it is a private car, a network car, or a cruise car, it is a tool for public motorized traffic. Because its common feature is to occupy urban public road resources, it should also have its social cost. As a low-load passenger transportation mode, we not only see the efficiency of its vehicle resources compared with the traditional rental industry, but also the inefficiency of occupying road resources compared with public transportation. In a city with a contradiction between supply and demand in Beijing, low-cost, especially the low-cost travel under the “burning subsidy†model should not be the main advantage of its competition with public transport.
As the two different modes of operation, the network car and the cruise car can meet the different needs of different travellers. With their respective suitable market space and service groups, the government should guide the two to form a benign competition and complementary relationship and promote Its coordinated development is of great significance to ensure the long-term sustainable development of the city's diversified travel service market. On the one hand, the network car and the traditional taxi are supplemented by public transportation, and jointly provide personalized travel services for the general public. Both can improve service quality and maintain stable and reasonable prices through moderate competition. However, for the elderly who do not use mobile phones and the specific people who do not want to use mobile phones, traditional taxi services will still be their first choice; in addition, in densely populated areas and hubs such as airports and train stations, travel demand During the peak hours, the advantages of accurate matching of supply and demand for net vehicles are no longer prominent, while the supply of traditional taxis is sufficient, and the management of stop and waiting is more mature, which is conducive to avoiding congestion caused by disorderly waiting in local areas.
In the use of big data means to achieve accurate matching of supply and demand, efficient scheduling, the use of Internet means to achieve service quality control and interactive feedback with passengers, the use of financing platform to achieve rapid market occupation, the network car has the advantage of the traditional cruise car is incomparable. For traditional taxi companies, they should actively embrace new technologies such as Internet + or big data to improve service levels and operational efficiency. For online car companies, they should actively cooperate with the government to regulate the number of vehicles, employees and vehicles. To promote the optimization of the overall transportation structure of the city is also the responsibility and obligation of the enterprise.
In a sense, the transportation system is also a huge market. But for an effective market, certain specific norms must be followed, such as consumer choice, competition, and cost-based pricing. This necessarily requires the constraints of legal regulations. In the future, the healthy development of new modes of transportation should increase the choice of road users (ie consumers) and encourage the healthy competition of transport operators. On the other hand, it should also make the price more accurately reflect the cost and create more Objective price and tax system. The economic cost of a network car should not only consider the use and operating costs of the vehicle, but also the social cost of occupying the road resources. As traffic congestion will lead to higher transportation operation costs, bring a lot of internal consumption of the city, become the main factor restricting economic development, and at the same time reduce the attractiveness and radiation of the city. Therefore, the government industry supervision department should respect the market. At the same time of law, we attach more importance to the efficient and fair use of public road resources, rationally regulate the scale and price of car rentals, and more importantly, improve the service level of urban public transportation and bicycle pedestrians, and give travellers a really attractive Green travel options.
