Fuel-efficient vehicles require safety, reliability, as well as user-friendly and modern external forms.
For example, low emission traffic zones, efficient parking management, imposing traffic tax and congestion charge, encouraging the use of clean and efficient vehicles, enforcing higher tax on buyers who choose vehicles with high energy consumption, and double tax on large cars and heavily polluting cars.
Perspective on policy "bottlenecks" for energy saving and emission reduction of China's motor traffic.

Which verifies that the NOTAM distribution service model is correct and effective. 1 Introduction Timely and effective aeronautical information services are an important part of air traffic management.
At present, the civil aviation aeronautical information processing system used in China is based on C/S(Client/Server) communication model, which receive, process and distribute all kinds of NOTAMs, generate pre-flight announcements and provide the inquiry services for users with NOTAM information, air traffic control and so on [1].
In order to ensure the safety and reliability of the System, publishers, subscribers need to log into the system with authentication.

The traffic is not perfect.
We should set up more tall buildings and try hard to build Tai’an City into a large city with the population of more than a million so as to make its construction march in step with the famous Mount Tai and the well-known international tourist city. 2.
We should increase the publicity of such festival activities as Taishan International Mountaineering Festival and Dongyue Temple Fair and highlight the characteristics of Taishan local culture.
We should also continue holding such activities as Taishan International Mountaineering Festival and plan other related tourist activities, which can effectively promote Tai’an’s tourist growth. 9.
We should actively enhance the management level of engineering quality, firmly grasp system construction, insist on the standardization and specialization in the construction process, perfect the construction quality and safety system of government’s and the masses’ supervision, social management and enterprise responsibility.

At the same time information platform of agricultural products posted on the latest international and domestic standards to guide production.
Consumers can also check the purchased product quality and safety through the platform, and for tracing the origin.
Consumers achieve orange quality and safety enquiries through information center, and can also make order directly on the internet.
At the same time it can help to improve the international competitiveness of China's agricultural products, and achieve an industrialized operation of agriculture.
