What road AIDS are there?

Question 1: What traffic safety facilities are included in road traffic safety facilities, which plays an important role in ensuring traffic safety and reducing the potential of accidents. A good safety facility system should have many functions such as traffic management, safety protection, traffic guidance, isolation and sealing, anti-glare and so on. Road traffic safety facilities include: traffic signs, pavement markings, guardrails, isolation guardrails, lighting equipment, sight-guiding signs, anti-glare facilities, etc. Road traffic signs include warning signs, prohibition signs, indicating signs, guiding signs, tourist area signs, road construction safety signs and auxiliary signs. The purpose of setting up traffic signs is to provide accurate information for road traffic personnel and ensure safe and smooth traffic. Expressway has high speed and many lanes, and the sign size is much larger than that of ordinary roads. Pavement markings include prohibition markings, indication markings and warning markings. They are traffic control facilities that are directly painted on the road surface or paved with concrete precast blocks into lines and symbols, which are used in conjunction with road signs. There are many kinds of pavement markings, such as lane centerline, parking line vertical markings, kerb markings, etc. There are solid lines, dotted lines, arrow indicating lines, etc. White or yellow paint is usually used. The safety guardrail on expressway should not only prevent vehicles from crossing the road, but also prevent vehicles from crossing the central divider and breaking into the opposite lane; At the same time, it must be able to induce the driver's sight. Guardrail is one of the infrastructures in expressway, which makes expressway completely closed and prevents people and animals from entering expressway. It can effectively eliminate lateral interference, avoid traffic delays or traffic accidents caused by it, and ensure the benefits of expressway. According to the different materials used, the isolation fence can be divided into metal mesh, steel mesh, barbed wire and evergreen hedge. Road lighting is mainly to ensure the safety and smoothness of traffic at night, which can be roughly divided into continuous lighting, local lighting and tunnel lighting. Lighting conditions have a great influence on road traffic safety. Sight guide signs are generally set along both sides of the lane, which have the function of indicating the road alignment and guiding the driver's sight. At night, on the road section where line-of-sight guidance is required, reflective line-of-sight guidance signs shall be set. Anti-glare facilities are designed to block the glare of headlights of oncoming cars, and are divided into anti-glare nets and anti-glare plates.

Question 2: What are the urban road traffic management facilities? Urban road traffic facilities can be divided into three categories according to their functions: traffic management facilities, traffic safety facilities and traffic service facilities.

Traffic management facilities include: traffic signs, traffic markings, physical isolation devices, traffic signal control equipment, traffic violation monitoring and capture equipment, etc.

Traffic safety facilities include: anti-collision guardrail and anti-collision column, anti-glare device, sight guiding facilities, bumpy road surface (speed bump), expressway reflector, etc.

Traffic service facilities include: parking lot, gas station, emergency telephone, etc.

Question 3: What auxiliary facilities are there for bridge foundation construction?

Question 4: What public facilities are there on the road? In fact, it is necessary to analyze specific problems, but as far as the development of the country is concerned, the main public facilities on the road are:

(1) Road traffic facilities: bus station, social parking lot, gas filling station, etc.

(2) Water supply and drainage facilities: feed pump station, sewage treatment plant, sewage pump station, rainwater pump station, etc.

(3) Power facilities: substations, urban power plants, etc.

(4) Communication facilities: long-distance office, end office, target office and long-distance hub office; Broadband (IP) office address; Mobile communication office address, mobile communication base station, etc. ;

(5) Radio and TV facilities: cable TV center, cable TV sub-center, cable TV community management station, etc.

(6) Gas facilities: LPG storage and distribution station, natural gas gate station, gas emergency repair station, etc.

(7) Fire fighting facilities: general fire fighting station, small general fire fighting station, road special fire fighting station, water special fire fighting station, helicopter special fire fighting station, fire fighting training base, fire fighting squadron, etc.

(8) Sanitation facilities: garbage transfer stations, garbage landfills, etc.

Question 5: What are the traffic management facilities in urban road management in China? There are three kinds of traffic management facilities in urban road management in China: traffic signs, traffic command signals and road traffic signs.

① Traffic signs

It is a device to indicate road conditions and traffic requirements. The traffic signs used on roads in China are divided into 3 categories and 34 kinds: indicating signs; Warning signs; Prohibition.

Signs are mostly installed on sign poles or hung on iron ropes across the road. The indicating sign pole and warning sign pole are black and white bamboo square poles, and the forbidden sign is red and white bamboo square poles, each side is 10cm wide. The installation height of the sign is from the ground to the lower edge of the sign 180 ~ 200 cm. The sign post should be located on the right side of the road 30 ~ 50 cm away from the roadside. The lower edge of the hanging sign should be outside the clear height limit of road vehicles.

The colors, sizes and shapes of the symbols in the world are basically the same. Mainly depends on the design speed of the road. The higher the speed, the easier it is to feel the signs and the greater the visible distance. The number of signs should be reduced appropriately, and the setting distance should be increased accordingly. In foreign expressway, it is required to minimize signs with * * such as warnings and bans, so that drivers will not be nervous and can drive safely without accidents, but they must be set up where necessary. Road numbers, place names and other guiding signs must be set up. On the road with a width of 6 ~ 8 lanes, the road signs set on the roadside are often blocked by the traffic flow. Therefore, on the wide expressway, important signs are often installed on the frame crossing the road, and the lights controlled by the circuit are coded into characters. The traffic control center uses variable characters to guide the traffic according to the needs of the traffic situation. In any light, the color and handwriting of the sign should be clear and easy to read.

In order to ensure the function of night signs unchanged, it is best to use reflective or luminous materials on busy main roads or expressway, and the brightness of reflective signs should be uniform without glare. Sign boxes can also be used on general roads. The lamp is installed in the box, and the logo pattern is painted on the glass of the logo box.

On the expressway, cars often collide with signboards. In order to reduce the loss in accidents, some countries use fragile cast aluminum as columns and use living hinges to connect the columns with signboards. After the car collides, the column just breaks and flips, and neither the driver nor the car will be seriously damaged.

② Traffic command signal

In the case of small cross flow, traffic police usually direct traffic. The advantage of this method is flexible management and no need to invest in equipment costs; If the traffic volume is large or there are special requirements, use signal lights to direct traffic. The advantage of this way is that it can reduce the labor intensity of traffic police, reduce traffic accidents and improve the capacity of intersections.

The signal lights shall be clear in color and uniform in brightness, and can be seen by drivers at a distance of 100 meters. At the same time, the signal light should also face the direction of the vehicle, so that drivers waiting in front of the stop line at the intersection can also see the change of the color light. If the sun shines directly on the surface of the signal lamp, a sunshade should be added on it. In order to avoid visual confusion, all lights that interfere with traffic lights at intersections should be removed. There are two ways to manage traffic lights: manual control and automatic control.

③ Road traffic signs

In addition to the above traffic signs similar to traffic lights, various pavement signs are widely used on urban roads. There are usually lane lines, parking lines, crosswalk lines (zebra crossings), guiding arrows, as well as dividing lines, public transport parking areas, parking lanes (and road edge lines in expressway). All these lines, arrows, characters or patterns that organize traffic are generally painted with white paint (or yellow paint) on the road surface, but also with white asphalt or cement concrete, white tiles or patterns.

Question 7: What equipment and facilities are needed for road closure? As the road surface collapsed, our project department was responsible for repairing the road surface. Due to several safety considerations in the construction, it is necessary to temporarily close the road section.

Question 8: What kinds of traffic safety facilities are included in road traffic safety facilities, which play an important role in ensuring traffic safety and reducing the degree of hidden dangers of accidents. A good safety facility system should have many functions such as traffic management, safety protection, traffic guidance, isolation and sealing, anti-glare and so on. Road traffic safety facilities include: traffic signs, pavement markings, guardrails, isolation guardrails, lighting equipment, sight-guiding signs, anti-glare facilities, etc. Road traffic signs include warning signs, prohibition signs, indicating signs, guiding signs, tourist area signs, road construction safety signs and auxiliary signs.
