Road Traffic Safety
It refers to the state in which personal casualties or property losses can be controlled at an acceptable level in the course of traffic activities. Traffic safety means that the possibility of loss to people or things is acceptable; if this possibility exceeds the acceptable level, it is unsafe. As a dynamic open system, the safety of road traffic system is not only restricted by internal factors of the system, but also disturbed by external environment of the system. It is closely related to human, vehicle and road environment. Any unreliable, unbalanced and unstable factors in the system may lead to conflicts and contradictions, resulting in unsafe factors or unsafe states.
(1) Traffic safety is a state under certain dangerous conditions, and it is not absolutely free from traffic accidents.
(2) Traffic safety is not an instantaneous result, but a description of the process or state of the traffic system in a certain period or stage.
(3) Traffic safety is relative and absolute traffic safety does not exist.
(4) For different periods and regions, the acceptable level of loss is different, so the criteria for measuring the safety of the transportation system are different.
Raising the level of road traffic safety is a matter of great benefit to the country and the people. Many experts and scholars have carried out extensive and in-depth research in this area. Traffic accident prevention is one of the main tasks of traffic safety and an important part of traffic engineering research. From the point of view of traffic engineering, it is considered that the prevention of traffic accidents should start from three aspects: laws and regulations, education and engineering, and from the point of view of people, vehicles, roads and environment, which constitute the four elements of road traffic, it is also considered that the prevention of traffic accidents should start from these four elements.
Improving Transportation Legal System
Strengthening the construction of road traffic safety laws and regulations system is a direct and effective measure to improve the overall level of road traffic safety. At present, the content of our country’s road traffic safety regulation system has been covered in a number of different laws, regulations and other traffic management normative documents, and it plays an active and important role in our country’s road traffic operation practice. With the development of the times, the legal system should be amended and adjusted accordingly.
Strengthen Traffic Safety Education
(1) Carry out traffic safety propaganda
Traffic safety propaganda is an important way to publicize and educate the masses. In carrying out propaganda activities, we should attach importance to achieving practical results and link traffic safety with everyone’s vital interests so as to arouse people’s attention to traffic safety. We should adopt propaganda forms popular with the masses, incorporate them in people’s daily work and life, and in cultural entertainment. At the same time, propaganda activities must mobilize the strength of society to the greatest extent possible, and strive for the depth and breadth of propaganda to ensure the quality of propaganda.
(2) Strengthen traffic safety education
Traffic safety education, like other cultural knowledge, should be carried out systematically from the early childhood. Before high school, every stage of education was listed as a compulsory course, which enabled students to establish the concept of traffic legal system, traffic safety, traffic ethics and safety prevailing concepts from the beginning of education. To educate the society, we should adopt different ways and methods according to different objects, and carry out targeted education.
Improve vehicle safety performance and maintain good vehicle condition
To improve the safety performance of vehicles, we should take active safety measures and passive safety measures.
(1) Active safety measures
1) Improve side and front vision, install reversing lights and alarms to prevent traffic accidents caused by blind areas.
2) Improve the perspective performance of windowpanes to prevent traffic accidents caused by rain, snow and frost.
3) Take anti-glare measures to improve the illumination of headlamp in order to prevent traffic accidents caused by glare and insufficient illumination of headlamp.
4) In terms of power performance, the overtaking acceleration capability should be improved and the drive anti-skid system (TCS) should be installed.
5) In the aspect of stability, we should improve the stability and portability of operation, such as installing electronic stabilization program (ESP).
6) In braking aspect, the auxiliary braking system, ABS anti-lock braking system, retarder and braking system fault alarm system are installed to improve the anti-skid performance of tires, so as to ensure safety.
7) In terms of accident prevention measures, we should also improve the recognition performance of vehicles, including rear, signs and driving directions, in order to prevent accidents.
8) Active anti-collision warning system is adopted. When the vehicle encounters danger, the driver can be reminded in time. If the driver fails to take measures in time because of his errors, the system can automatically take measures to avoid danger (such as deceleration, bypass, etc.).
(2) Passive safety measures
1) In-car measures
In-car measures mainly include increasing occupant space as much as possible, i.e. the strength of the car body, in order to reduce the deformation of the collision, using toughened glass or partition glass to reduce the injury of the occupant caused by the accident, enlarging the area of the steering wheel to make it elastic, and making the switches, knobs and handles inside the car as round as possible. Sliding and soft; door and roof have enough strength to protect the safety of passengers and facilitate rescue. In addition, fire prevention performance, safety belt and airbag play an important role in occupant safety protection.
2) Outside measures
Extravehicular measures mainly refer to minimizing injuries when crashing bicycles and pedestrians, such as bumpers should be as smooth and flexible as possible, movable rearview mirrors and fenders, and protective nets connected with trailers, etc., which will have certain effects on the protection of the weak traffic.
Strengthen the Construction of Road and Traffic Safety Facilities
(1) Improving road conditions
Considering from the aspect of road alignment design, we should strictly follow the horizontal and vertical curves of the designed road to make the curves and ramps conform to the technical standards of highway engineering. The safety of various alignment combinations should be fully considered.
(2) Improving road safety facilities
Road safety facilities mainly include partition belts, safety fences, traffic signs, markings, sight guidance facilities and anti-glare facilities. For urban traffic, pedestrian overpasses, underground passages, traffic safety islands, etc.
(3) Implementing traffic control
Traffic control can be divided into traffic signal control and traffic regulation control. Traffic signal control refers to the establishment of traffic lights at road entrances and intersections to reasonably control the driving of vehicles. Traffic regulation control includes setting up one-way traffic section, turning lane, bus lane, etc.
(4) Establishment of Traffic Information System
Traffic information is also known as traffic information. In order to ensure the safety and rapidity of vehicles traveling on automobile lanes or urban trunk roads, public security and management departments should report traffic congestion, weather, road ahead or temporary traffic control to drivers in time so that drivers can change their countermeasures in time.
(5) Establishing Emergency Rescue System for Accidents
The monitoring and forecasting system estimates possible accident areas according to abnormal weather conditions, adopts information collection and liaison system, and assigns special personnel to monitor and make preparations. When an accident occurs, advanced communication equipment and means should be used to quickly and reliably contact the relevant departments to deal with the accident in a timely and effective manner so as to ensure road safety and smoothness.
(6) Improving the Road Traffic Environment
The improvement of road traffic environment mainly includes two aspects: on the one hand, improving road environment, making drivers have good driving sight distance and constantly changing visual effect, improving the monotonous environment which makes drivers tired and irritable; on the other hand, improving traffic flow environment, keeping good density as far as possible, and avoiding as possible. No mixed traffic flow.

Cow dung, which is also known as cow manure, is a natural by-product of the cattle industry. It is a rich source of nutrients and organic matter that can be used to improve soil health and promote plant growth. However, cow dung is typically quite difficult to handle and process, as it is often wet and contains a high percentage of water.
The cow dung powder making machine is designed to overcome these challenges by drying and pulverizing the cow dung into a fine powder that can be easily stored, transported, and applied to crops. The machine consists of several components, including a drying system, a pulverizing system, and a screening system.
The first step in the process is to dry the cow dung. This is typically done by exposing the dung to heat in a drying chamber. The temperature and humidity inside the chamber are carefully controlled to ensure that the dung is dried thoroughly but does not become too hot or brittle.
Once the dung is dry, it is pulverized using a machine called a pulverizer. This machine uses a series of blades or hammers to break the dried dung into small particles. The particles are then screened to remove any large or uneven pieces, leaving behind a fine powder that is ready to be used as fertilizer.
The cow dung powder making machine offers several advantages over traditional methods of processing cow dung. For one, it is much faster and more efficient, allowing farmers to process large quantities of dung in a relatively short amount of time. Additionally, the machine is much more hygienic than traditional methods, as it reduces the risk of contamination from pathogens and other harmful microorganisms that can be present in wet cow dung.
