A few days ago, the reporter learned from the Yanqing Highway Sub-bureau of the Beijing Municipal Commission of Transportation that Yanqing District has successfully completed the construction of the “smart road” on Songyan Road, which is a high-level hosting of the Winter Olympics and improved emergency response capabilities and traffic service levels in the Yanqing competition area of the Winter Olympics. It has laid a solid foundation for the traffic safety of the competition area.
Songyan Road is one of the important venue links in the Yanqing competition area of the Beijing 2022 Winter Olympics. It is also the only local road that enters and exits the Yanqing Winter Olympics area except for the Yan-Chong Expressway. Since the beginning of the reconstruction of Songyan Road in 2018, Yanqing District has always adhered to the concept of the Science and Technology Winter Olympics. After many on-site surveys, scientific judgments and reasonable planning have been made for the special road conditions of Songyan Road. Songyan Road starts at the G110 intersection and ends at Yanjiaping Village, Chicheng County, Hebei Province, with a total length of 17.7 kilometers. Because it runs through Songshan National Natural Forest Reserve, it is inconvenient to use large-scale construction methods to improve traffic conditions. Yanqing Highway Branch insists on scientific and technological means To support, optimize traffic conditions, fully implement the technology Winter Olympics concept, improve the comprehensive perception of the road network, and provide data support for road traffic safety and efficient traffic.
It is reported that there are 116 sharp “S” and “U” bends on Songyan Road, which pose hidden dangers to driving safety. In response to this problem, the Yanqing Highway Sub-bureau installed 96 sets of early warning systems for blind spots in bends on Songyan Road. At the forefront of each curve, the host of the curve warning system is installed, and then intelligent road piles with different distances and different numbers are installed according to the arc and length of the curve. After the vehicle reaches the monitoring range of the curve warning system, it is detected by infrared rays. The host will display the words “a sharp bend ahead”, and the smart pilings at the back will display arrow shapes in turn, marking a clear curve contour for the driver, and a voice reminder of “going ahead” when meeting cars. At the same time, the speed measurement function is added to the continuous curved road section, and the driver is reminded to slow down.
The scientific and technological power of the curve warning system does not stop there. It can also automatically adjust the light color and flashing state under different low-visibility weather conditions such as night, fog, rain, etc., highlight the road sideline and vehicle distance reminder, which can effectively reduce road traffic The accident happened.
Many bends are just one of the main features of Songyan Road. During the Winter Olympics, it is a severe winter. Songyan Road is located in a mountainous area. There are more than 20 steep and rugged mountain roads that are prone to icing. Once it snows, it is easy to form dark ice. To this end, the Yanqing Highway Branch has installed two ice and snow warning systems on Songyan Road. The high-precision laser and radar sensors of the meteorological monitoring sensors can quickly determine the ground temperature, humidity, and snow and icing information, especially when it snows in winter. The thickness of the snowfall is quickly and accurately measured and transmitted to the information platform in real time to notify relevant departments to deal with it in a timely manner.
In order to ensure the safe travel of pedestrians during the Winter Olympics, Songyan Road also set up a safety flower detection platform in the blind area of the level crossing. When pedestrians enter the detection area, the system will issue a prompt “Pay attention to safety at dangerous intersections ahead”. , The humanoid cursor will also be thrown on the ground to turn on the light warning to remind travelers to avoid. These multi-functional smart terminal devices have now entered the commissioning stage, and the application of the entire “smart highway” will reach its best state during the Winter Olympics.
It is reported that at the end of 2018, Songyan Road has completed the installation of information boards, video surveillance and conventional equipment for laser intermodulation. In addition to the completion of the construction of the “smart highway”, the overall safety factor of Songyan Road has been improved, and the technology Winter Olympics concept has been obtained. Further implementation, these will provide road guarantee for the traffic safety of athletes, referees and spectators during the Winter Olympics.
“The Yanqing Highway Sub-bureau installed 119 sets of highway information collection equipment in the construction of the Songyan Road Smart Highway. After a year of operation and commissioning, it will play an active role in the transportation guarantee for the Winter Olympic Games.” Yanqing Highway Sub-bureau Road Network Management Division works Personnel Fan Anran said, “At the same time, the Yanqing Highway Branch will use the Songyan Road’smart highway’ as a model, and will increase scientific and technological means in future road construction to provide more powerful guarantees for citizens’ safe travel.”
