How to calculate the distance between vehicles on the highway 200 meters

In the design of highways, the distance between vehicles varies according to the speed of the vehicle.

In general, road studies have shown that the distance between vehicles is the speed of the vehicle multiplied by the second. If the speed is 10ms, then the distance between the vehicles should be kept at 10*. However, considering that individual drivers may not be so fast, it is increased to seconds.

The speed of 120kmh only needs to be maintained, and the distance between the vehicles can be maintained.

When I arrived at the traffic police department, in order to reduce the occurrence of car accidents, the stopping sight distance (210m) of the highway was used as the driving distance, and it became 200m.

Therefore, you can according to your own situation, if you are an old driver, then keep the distance between the seconds between the cars, if you are a new driver, according to the distance of seconds, you can ensure safety.

The driving speed should be determined by the reaction time of the person and the braking distance used when the car slows down to 0 meters and seconds in a certain speed.

A normal person can go from spotting an obstacle in front of him to making a stop or deceleration action in a second.

If the visibility is 100 200 meters, if the car is reduced from 100 km h to 0 the required stopping distance is 100 meters. At this time, the car should be controlled within 80 kilometers and hours, because when driving at 80 kilometers per hour, the reaction time of 100 meters is seconds, and 200 meters is 9 seconds. It is guaranteed to stop and avoid obstacles in time when obstacles are found 100 meters away.

If the visibility is 100 200 meters, if the car is reduced from 100 km h to 0 speed required to stop at 50 meters. At this time, the car should be controlled within 100 kilometers per hour, because when driving at 100 kilometers per hour, the reaction time of 100 meters is seconds, and 200 meters is seconds. It is guaranteed to stop and avoid obstacles in time when obstacles are found 100 meters away.

This means that driving on the road gives you plenty of reaction time, which is the speed and distance between the front and the back. The 200-meter distance sign on the highway is to give drivers a sense of distance on the highway. This distance of 200 meters is also a safe distance for vehicles to travel at high speeds.

300 meters around extra-large and chaotic bridges on expressways, 200 meters around large and medium-sized bridges, and 100 meters above or outside the tunnel opening, no sand digging, quarrying, soil extraction, dumping waste, blasting, underground mining operations and other activities that endanger the safety of the expressway shall be allowed. Within the scope of the preceding paragraph, if it is necessary to build a dam, compress or widen the riverbed due to emergency rescue and flood control, it shall be reported to the provincial transportation department in conjunction with the provincial water conservancy administrative department for approval in advance, and effective measures shall be taken to protect the expressway.

Regulations on the Protection of Highway Safety

Article 11. Local people at or above the county level shall, in accordance with the principle of ensuring the safety of highway operation and saving land and the needs of highway development, organize departments such as transportation and land resources to delineate the scope of highway construction control areas.

The scope of the highway construction control area, the distance from the outer edge of the highway land to the outward is as follows:

1) National highway not less than 20 meters;

2) Provincial roads not less than 15 meters;

c) The county road is less than 10 meters;

4) The village road is not less than 5 meters.

If it belongs to a highway, the scope of the highway construction control area shall not be less than 30 meters from the outer edge of the highway land.

The scope of the building control area on the inside of highway curves, interchanges and level intersections shall be determined according to the requirements of safe sight distance.

The speed of the vehicle shall not exceed 60 kilometers per hour, and the distance between the vehicle in front of the vehicle in the same lane shall be more than 100 meters. 1. According to Article 81 of the Regulations on the Implementation of Road Traffic Safety of the People's Republic of China, motor vehicles shall comply with the following provisions when driving on the highway under low visibility meteorological conditions such as fog, rain, snow, sand and dust, hail:

1. When the visibility is less than 200 meters, turn on the fog lights, low beams, marker lights and front and rear position lights, and the speed shall not exceed 60 kilometers per hour, and keep a distance of more than 100 meters from the front car in the same lane; 2. When the visibility is less than 100 meters, turn on the fog lights, low beams, marker lights, front and rear position lights and hazard warning flashing lights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicles in front of the same lane; 3. When the visibility is less than 50 meters, turn on the fog lights, low beams, marker lights, front and rear position lights and hazard warning flashing lights, and the speed shall not exceed 20 kilometers per hour and leave the highway from the nearest exit.

What is the distance between cars on the highway? Let's find out.

Under normal conditions on the highway, when the speed of the car is 100km h, the safety distance is more than 100m; When the speed is less than 100kmh, the safety distance can be appropriately reduced, but the minimum distance shall not be less than 50m.

Note: When driving on the highway, when encountering low visibility meteorological conditions such as fog, rain, snow, sand, dust, hail, etc., the following regulations shall be observed:

1. When the visibility is less than 200 meters, turn on the fog lights, low beams, marker lights and front and rear position lights, the speed shall not exceed 60 kilometers per hour, and keep a distance of more than 100 meters from the vehicle in front of the same lane;

2. When the visibility is less than 100 meters, turn on the fog lights, low beams, marker lights, front and rear position lights and hazard warning flashing lights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicles in front of the same lane;

3. When the visibility is less than 50 meters, turn on the fog lights, low beam old and missing, marker lights, front and rear position lights and hazard warning flashing lights, the speed shall not exceed 20 kilometers per hour, and leave the highway as soon as possible from the nearest exit.

What is the Highway Distance Confirmation Sign used for?

Highway distance confirmation signs are used to provide a reference for vehicle drivers to maintain a safe driving distance, and are used in conjunction with vehicle distance confirmation signs.

Driving fast on the highway is very fast, and in order to ensure safety, it is important to keep a safe distance between vehicles. However, it is difficult to judge the distance between the car and the car in front when driving, so the highway will set up a distance confirmation sign every other section to help the majority of drivers confirm the distance between themselves and the car in front and adjust the distance.

When the front of the car through the moment of 0 meters, observe the car in front, if the front car tail has passed 50 meters, the distance between the car remains above 50 meters, if the front of the car has passed 100 meters, the distance between the car remains above 100 meters, and so on.

The above is today's sharing, I hope it can help you.

Legal analysis: The distance between vehicles on highways is determined according to the speed of the vehicle, and the distance between the vehicle in front and the vehicle in front should be at least 50 meters.

The regulations for the implementation of the Road Traffic Safety Law of the People's Republic of China stipulate that the following distance is as follows:

1. When the motor vehicle is driving on the highway and the speed exceeds 100 kilometers per hour, it shall keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is less than 100 kilometers per hour, the distance between the vehicle in front of the vehicle and the same lane can be appropriately shortened, but the minimum distance shall not be less than 50 meters;

2. When a motor vehicle is driving on the highway and encounters low visibility meteorological conditions such as fog, rain, snow, dust, hail, etc., when the visibility is less than 200 meters, turn on the fog lights, low beams, marker lights and front and rear position lights, and the speed shall not exceed 60 kilometers per hour, and keep a distance of more than 100 meters from the front car in the same lane;

3. When a motor vehicle is driving on the highway and encounters low visibility meteorological conditions such as fog, rain, snow, sand, hail, etc., when the visibility is less than 100 meters, turn on the fog lights, low beams, marker lights, front and rear position lights and hazard warning flashing lights, and the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the car in front of the same lane;

4. When a motor vehicle is driving on the highway and encounters low visibility meteorological conditions such as fog, rain, snow, dust, hail, etc., when the visibility is less than 50 meters, turn on the fog lights, low beams, marker lights, front and rear position lights and hazard warning flashing lights, and the speed shall not exceed 20 kilometers per hour, and leave the highway as soon as possible from the nearest exit.

Legal basis: Article 80 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China.

When a motor vehicle is driving on the highway at a speed of more than 100 kilometers per hour, it should keep a distance of more than 100 meters from the vehicle in front of the same lane, and when the speed is lower than 100 kilometers per hour, the distance between the vehicle in front of the vehicle in the same lane can be appropriately shortened, but the minimum distance shall not be less than 50 meters.

The speed of the car is 80-120 kilometers per hour, the novice on the road in the middle lane, the leftmost side is the overtaking lane, the rightmost is the emergency lane, the emergency lane is generally not allowed to drive, the emergency lane is the slow lane, and then the normal driving lane. On the highway, the speed of the car is from left to right, from fast to slow. Novices on the road speed is generally kept at 80-100, do not change lanes at will, pay attention to the trial of turn signals.

Try not to stop on the highway again, and try to keep the emergency lane as much as possible, and park in the nearest service area.

The maximum speed shall not exceed 120 kilometers per hour, the minimum speed shall not be less than 60 kilometers per hour, and the distance between the two vehicles shall be more than 100 meters. The first time you drive on the highway, keep your distance, hold the steering wheel tightly, and look straight ahead. gogo
