Will the Typhoon Highway be closed?
During the Typhoon attack, the decision to close the highway is not a “one-stop” decision, but is dynamically adjusted by the police and road administration departments according to live Weather data and road conditions.In general, when the weather department releases a Typhoon yellow, orange or red early warning signal, and is accompanied by heavy rains, heavy winds and other bad weather, temporary traffic control measures may be taken in some sections of the road to ensure traffic safety.
The main factors affecting high-speed passages include visibility, moisture level and wind intensity. If Typhoon's Rainstorm causes low visibility at 50 meters, or the road area is heavy water, the police department will usually implement distribution or closed entrances. In addition, mountain highways also need to be alert to typhoon-induced mountain slopes, mud and other secondary disasters. Therefore, even if there is no direct Landfall, the outer clouds can cause local section of the road to be closed. It is recommended that you inquire about the latest road conditions via navigation software, traffic radio or local police official microblog before travel, do not blindly enter the highway. If you are already in highway control, stay calm, listen to the command of the scene, wait for the nearby department or toGo
How high is the bridge?
The cross-sea bridge is opened by the sea surface, lack of land coverage, its wind force is often larger than the land, and is susceptible to the effect of the "strict tube effect". therefore, the closure standard of the cross-sea bridge is more stringent than the ordinary road, mainly based on instantaneous wind speed rather than average wind speed.
Generally speaking, when the bridge facade measurement wind force reaches a certain level, the bridge management will start the level control plan:
- Speed limitationWhen the wind force is greater but has not yet reached the hazardous threshold (for example, around the wind level 7-8), the bridge may restrict the model, prohibit the passage of high-gravity vehicles such as trucks, buses, etc., and only allow small buses to pass at low speed.
- Totally closedWhen the wind force of the bridge reaches level 9 or above, or the meteorological department issues a typhoon orange or above early warning, and predicts that the wind force will continue to increase, in order to ensure absolute safety, the cross-sea bridge usually implements a double toward closure.
It should be noted that different bridges have different design wind resistance standards and geographical position, the specific bridge wind force thresholds may vary.The local standards may vary, depending on the local government issued.For example, some super-long cross-sea bridges may be closed in advance at wind force.The public should pay close attention to the notice issued by the bridge administration, do not try to force over the bridge when the wind force is strong.
Scientific Defense, Safety First
For Typhoon, the most core principle is “avoid”. China Meteorological Agency divides tropical cyclones into Nameless, Tropical Storm, Severe Tropical Storm, Typhoon, Severe Typhoon and Super Typhoon six levels.
During Typhoon impact, try to minimize unnecessary exits. If you have to travel, avoid advertisements, trees, temporary buildings and other potential sources of danger. for at Drivers, do not get stuck with water in accumulated road sections, so that the vehicle does not get stuck. At the same time, pay attention to the weather warning information released by the official channels, prepare the household for wind and rain, reserve the necessary food and drinking water.
