Iasi through the mountains of high-speed, complex road, tunnels and numerous bridges, "s" curve and the long ramp to a connected one, the traffic police involved in an inquest, if you want to ensure safety, Iasi high-speed can not, as generally high-speed limit speed of 120 km, some dangerous sections of the speed limit may be 80 km or even less.
"That is a called a magnificent road, but it at any time may become a dangerous path." Who participated in the inspection of the traffic police said.
Strict Management of Iasi 240 km, 120 police force
For the forthcoming opening of Iasi high-speed, security, traffic problems caused by the high degree of attention of the Provincial Public Security Bureau Traffic Police Corps. Sichuan high-speed traffic police set up a special four traffic police brigade, the whole jurisdiction of the Iasi high speed. Each brigade will be equipped with at least 30 police officers, the entire 240 km more than 120 police officers, province highway management the most.
Large vehicles mandatory security
For the protection of of Iasi high speed traffic safety, traffic police department will be large vehicles, especially vehicles transporting hazardous chemicals to strict control. Interoperability of high-speed at both ends of Yingjing interoperability and Yi sea, respectively, the establishment of a mandatory safety inspection station, all the major vehicle through pit stop to check.
Important to Remember
Do not Iasi when high-speed
"Please Do not Iasi when high-speed." This is to participate in the the finished Iasi high-speed full inspection of high-speed traffic police, please reporters must remind the drivers of the sentence. Iasi high speed is a highway, but from the point of view of safe driving, traffic police also hope to pilot it as a completely closed the highway, "Simply put, just do not want to run takes a common highway fast. "
Can not be 5 hours to Xichang
The Iasi high speed indeed closer to Chengdu with the the Panxi sun distance, say 5 hours Chengdu to Xichang, by actual inspection, but it is not realistic. Under normal weather conditions, does not appear traffic jams and other high-speed, Iasi full takes about four hours. Coupled with the distance of Chengdu to Ya'an and Lugu to Xichang from Chengdu to Xichang need at least 6 hours. If the winter is extreme bad weather, this time may also extend to many.
Landscape, although the United States to refrain from parking
Through the Iasi high speed, you will experience the feeling of a stroll in a cloud, like riding a dragon through the mountain valley, the scenery along the beautiful. But this does not become the reason you can be on the road parking viewing. The traffic police in Iasi high-speed illegal parking, only two results, either an accident or waiting for a fine of 200 yuan note of the 6 points penalty.
Long ramp
Length of 51 km
Large trucks continuous downhill 30 km, the brake system will reach a critical point of failure
The lowest elevation of 630 m and 2440 m, the highest, and this is the Iasi high-speed and takes across the elevation found, from the mud Alexander phase Ridge drag the Osan Buddha Kong, next to the Dadu River valley, destined to a long ramp is high-speed main theme.
Iasi high-speed, three segments of long continuous ramp must pay special attention to. Are ramp from Yingjing to the mouth of the large relative to the tunnel north for 33 km, 26 km in a row from the tunnel of South Side, to Hanyuan ramp, and the longest for 51 from asbestos to drag the Osan Bodhisattva Kong tunnel km ramp.
The most dangerous section is extremely rare in the domestic highway 51 km long continuous ramp, along the way almost all bridge and tunnel sections, the Iasi high-speed the most striking Ganhaizi, iron stockade double helix tunnel is located this ramp. 51 km of continuous downhill What is the concept? According to traffic police, the department had specifically done the experiment, a large truck in the case of overloading, continuous downhill 30 km, the brake system has reached a critical point of failure.
In addition to long, of Iasi high-speed Shangpo Dao Another feature is the slow, slow people are not easily detectable. The traffic police suggested that the driver in motion and be sure to pay attention to the speed of the table, control the speed.
Security measures: set the parking areas and hedge lane
In order to ensure that the vehicles in continuous long downhill road safety, Iasi high speed in several long ramp set up a special parking area and hedge lane.
The parking area is designed to provide dock downhill on the way to large vehicles, heat cooling to the brake system. Iasi high-speed high-speed Sichuan first set up as many as 12 hedge lane for vehicles in the emergency parking brake failure.
Continuous curve
Even the "s" bend
From large tunnel of Nankou, exit, continuous downhill along a continuous curve
Iasi high-speed known as a "bend" high-speed was not excessive. Length of 240 km away, in addition to the end of a section of the Anning River Plain, the rest almost entirely composed of corners, and even across the Dadu River guanyinyan Bridge from a distance was one of the "s".
Inspection found that the traffic police, Iasi high-speed continuous "s" bend very much, the vast majority of corner turning angle is smaller, but the corners are generally longer, which means that the driver must be a long time the steering wheel to keep at the right turning angle, a little attention to the vehicle deviation.
In all the corners, the southern slope of the 18 most in need of attention is the mud mountain with the "s" bend. Large relative to the tunnel south exit of the exit is 26 km downhill, until the Dadu River Valley Hanyuan. 26 km downhill, along with 18 in a row "s" bend, more than one of the corners of the turn angle over 20 degrees.
Security measures: above the speed limit electron capture speeding
The continuous curve is the safest way is only one word: slow. According to traffic police, high-speed vehicle speed limits in Iasi has not yet finalized, the current speed limit of the province's major highways is 120 km, but the actual inspection of the situation, if you want to ensure safety, Iasi high-speed part of the dangerous sections of the speed limit may be 80 km or even less.
Iasi high-speed electronic capture of the entire system has been basically set up the set of dangerous sections of the electronic eye is more intensive, focusing on capturing speeding violations.
Long tunnel
North-south temperature difference between 10 ℃
Mud mountain watershed of Ya'an damp areas and asbestos dry river valley area
Up to 10 kilometers of mud Alexander relative to the tunnel, is a spectacle on the Iasi high-speed. However, it is also the most difficult sections of the traffic police.
Headache stems from two aspects. First, climate, Daxiangling mud mountain watershed of Ya'an damp areas and asbestos dry river valley area. Mud on the north slope perennial misty, rainy and humid, while the southern slope of the dry hole temperature of the tunnel of north and south of 10 ° C. The vehicle into the south mouth of the sun shining brightly, a north hole, it could be foggy, there is a big security risk.
Second, large relative to the tunnel 10 kilometers long, in the event of accidents, hedging and rescue operations will be challenged. The traffic police reminded, once driving in a tunnel accident, the persons on board must immediately set up warning signs at a safe distance, and as soon as the emergency parking area to the nearby hedge.
Security measures: the tunnel full of video surveillance
Large relative to the tunnel safety issues, construction is already taken into account. In the tunnel, as far as 150 m intervals, every 50 meters there is a surveillance camera, and basically can do no dead space monitoring during the entire tunnel. Inside the tunnel in the event of an accident, do not need to wait until the driver active alarm, traffic police will be able to monitor the first time carried out the rescue.
Dark ice latent
Winter hidden
Yingjing to drag Osan the Bodhisattva Kong about 180 km sections focus observation
Although high-speed Iasi success through the mud mountain, drag Osan two mountains, but the shadow of the winter ice has not yet dispersed. And appear dark on the highway of ice, I am afraid that will bring greater security risks.
According to the information provided by the Iasi highway, in December of each year to next March, on the north slope of mud and drag the height of the Osan northern slope of a certain elevation on the frozen snow cover. Hanyuan to asbestos on the way across the Dadu River and Pubugou Reservoir, several bridges, winter knot of dark ice.
At present, the traffic police department from Yingjing to drag Osan the Bodhisattva Kong about 180 km road sections are listed as the key observation section of the winter ice.
Security measures:
The proposed three management and control plan
May be frozen for the high-speed winter of Iasi, high-speed traffic police intends to develop a special set of three control plan.
Slight icing on the road, the traffic police will take the vehicle grouping by Results team. Moderate icing occurs, the traffic police, in addition to vehicle classification grouping, will send a police car with the Road. When the road surface to severe icing, the traffic police will immediately implement temporary traffic control, temporary closure of the ice sections.
The whole experience
Ya - Ying by 26 km
From Chengdu to go into the elegant high-speed, the next station arrived in Ya'an without conversion, can be directly on the Iasi high speed. The whole to a level road and downhill from Ya'an to Yingjing more on the way corners, but the speed can be basically maintained at about 100 km journey takes about 20 minutes.
Yingjing - Hanyuan 59 km
From Yingjing Hanyuan road is one of the Iasi high-speed full of the most scenic sections. Shortly after departure from the Yingjing to enter a continuous uphill section to go through during Asia's first pier, 200 meters Laba pounds Bridge, across the Long Cang Ling virgin forest, up to 10 km large relative to the tunnel.
The road at full speed is best controlled at about 80 kilometers per hour, travel about 40 minutes.
Hanyuan - Asbestos 31 km
Hanyuan to asbestos is the the Iasi high-speed, relatively flat section of the whole walk through along the Dadu River valley winds. The way across the reservoir of the Dadu and Pubugou three times, nearly half of the journey are in the bridge and tunnel traffic, and still more corners, but most of the relatively slow. The speed can be maintained at about 100 kilometers per hour, the journey takes about 20 minutes.
Asbestos - the Mianning 95 km
This journey need to climb to drag Osan whole Iasi high-speed on the most dangerous sections. Starting from asbestos, after the tunnel Jigongshan began the 51 km long uphill on the way to go through a number of bridge and tunnel sections. The most spectacular than the dry Hai Zi, iron stockade double helix tunnel. The whole average speed is best controlled at less than 100 kilometers per hour and the journey takes about 1 hour 20 minutes.
Mianning - Lugu 29 km
This is the last paragraph of Iasi speed is best to go for some, the whole trip traveling in the Anning River Plain. Speed can reach 100 kilometers per hour, travel about 15 minutes. Lugu is a high-speed end of Iasi, to Xichang, and should continue along the Lu yellow high speed of about 55 km. Source: WCC
