traffic accident
1. Big trucks: When you come out of Chengdu, you will encounter a large number of dense big trucks on 3 18. This situation will be much better after crossing the mountain. Many large trucks on the road are braking and smoking, and you can feel the heat wave from your experience. There is no special bicycle lane on the national highway, so it is inevitable to grab the lane with big trucks. There are often big trucks passing by, which is quite dangerous from the back of the cyclist. If the driver is careless, such as in the wrong direction, he will hit the cyclist. It's no use being careful, he can only rely on luck.
2. Road safety: crater road, rain road, cliff road, sand road and river road. These problems are not too big on uphill and peaceful roads, which will affect the riding speed, but they are more dangerous when going downhill at high speed, which will easily lead to falling off. If you ride to the edge of the cliff, you will encounter a bad road and fall off the bus, and the risk factor is quite large. When you encounter a bad road downhill, try to ride it slowly. Falling off a car is not fun. Sichuan-Tibet line has limited medical conditions.
3. Long downhill: It is easy to run at a high speed when encountering good roads, such as xinduqiao, where some people are more than 60 kilometers. The consequences of falling more than 30 kilometers should be clear.
4. chasing dogs: going uphill is most afraid of being chased by dogs. Bring something to eat and feed the dog. I can't get off the bike.
5. Chasing children: Try not to give them anything, get into the habit of asking for something, and the rider behind will be dumbfounded. If it really doesn't work, give them some small sweets.
6. Fatigue driving: lack of sleep. I go to bed early at night. Have a chance to rest and sleep for a while during the day. There are plenty of places to sleep on the roadside, but I remember not to catch cold when I sleep. Adequate sleep is not easy to cause judgment problems.
7. Cliff: I ride on the edge of the cliff most of the time, such as Goer Temple and Jueba Mountain. Remember to ride on this side of the mountain. It is hopeless to fall off the cliff. While riding, you should also pay attention to whether there are falling rocks on the mountain. If the road is wide, ride in the middle.
8. sharp turn: downhill to the corner must be slow, and then ride when there is no car. I've seen cars turn and overtake many times. If they ride fast, they will hit directly and there is no way to hide. It will be even more dangerous if you are caught by the big truck in front when you make a detour.
second kind
natural disaster
1. Rockfall: This probability is relatively high. After all, you often ride a horse against the mountain, but if a stone really hits you, the probability is still very low.
2. landslide: this will affect travel, and it is not convenient to ride a bike when repairing roads.
3. Debris flow: 20 1 1, the debris flow interrupted the traffic, and many riders were trapped and unable to move forward.
4. freezing rain: the rain on the plateau is very cold, and the consequences are more serious, which may lead to a bad cold and make it impossible to ride.
5. Heavy rain: Riding in the mountains in heavy rain is lonely and even a little scared.
6. Snow: If there is snow on the road when going downhill, it will be slippery.
7. Hail: Occasionally.
8. Strong wind: Riding against the wind is very tiring. When going downhill, pay attention to the strong wind blowing in the riding direction.
9. Extremely hot and cold: Riding can sometimes experience four seasons in one day. You can prevent heatstroke when it is hot; When it is cold, you can prevent freezing and keep changing clothes. Prevent diseases.
The third category
public health
1. High response: cycling is generally not too serious. It is much better to ensure sleep and maintain physical strength. It is very useful to take some glucose oral liquid to supplement your physical strength. Oral liquid with inosine is also effective. If you don't bring it, you should buy it in Kangding. It's inconvenient to buy it later.
2. Food: Pay attention to hygiene and don't eat bad stomachs. Eat more, meals are generally free.
3. Cold: Take cold medicine. If you get caught in the rain, blow dry with a hair dryer. When you arrive at your destination every night, blow yourself with a hair dryer to prevent colds and be more refreshing.
4. heatstroke: bring some salt, don't let yourself collapse.
5. Water source: Don't drink roadside water, raw water is still very dangerous.
6. Hunger: Remember to bring more dry food at a time, which is easy to overdraw.
7. Physical overdraft: Glucose oral liquid takes effect quickly.
8. Water and salt loss: bring some salt.
9. Muscle strain: Pay attention to riding posture and have a proper rest.
10. Accommodation: The sanitary conditions of accommodation are generally not very good. Wear more clothes when sleeping.
The fourth category
Car safety
1. Brake: There are enough brake bands. Don't expect to borrow it from others on the way. It's hard to be a man. Check the brakes more and wash the car after a bad road.
2. Rear-end collision: Keep the distance between teammates, especially when going downhill.
3. Inverted parallel: If there is a big truck, never ride side by side.
4. Night walk: Sometimes you need to walk at night. Remember to bring flashlights and taillights. It's more dangerous to cross the tunnel without taillights.
