📋 Tender Overview
Vietnam Road Administration (Ministry of Construction) has just piloted the installation of a solar reflective stud system on the route, marking another step in applying smart technology to overcome the limitations of the road signaling system and improve traffic safety.

This is a vital route connecting Hanoi with the Northwest provinces with complex operating conditions, many consecutive bends, dense fog, slippery rain and poor visibility. mechanism, potential risk of traffic accidents, especially at night. The route selected for the pilot has a road surface width of 7-9m, a roadbed of about 9m, located on a pass area with many consecutive curves and a vertical slope of 2-5%. This is also an area often affected by adverse weather. During the rainy season, the road surface is slippery and thick fog causes the drivers visibility to be significantly limited. Meanwhile, the traditional signaling system mainly relies on the ability to reflect light from vehicle lights, so the effectiveness of identifying route directions at bends and hidden locations is not really optimal, increasing the risk of traffic accidents. Putting new technology to the test. Starting from this reality, the Vietnam Road Department decided to put new technology to the test to add a visual warning layer, helping drivers clearly recognize road edges, route directions as well as dangerous locations. from a longer distance. Accordingly, the Vietnam Road Administration has allowed Road Management Area I to pilot the installation of a solar reflective stud system on the section Km 176+200 - Km 176+700, National Highway 6, in Van Ho commune, Son La province. During the implementation process, Road Management Area I and related units will closely monitor the site, ensuring the construction fully complies with safety regulations. traffic, does not affect traffic activities on the route. Vietnam Road Administration said that this solution aims to evaluate the effectiveness of smart traffic devices in enhancing the ability to warn and guide vehicles on road sections with difficult operating conditions, especially at night or in adverse weather conditions. Download The solution aims to evaluate the effectiveness of smart traffic devices in enhancing the ability to warn and guide vehicles on roads with difficult operating conditions, especially at night or in adverse weather conditions. Evaluate the effectiveness for consideration of replication. Unlike traditional reflective spikes that only reflect light from vehicle lights, the solar reflective stud system has the ability to actively glow. During the day, the device self-absorbs and stores energy through sensor panels. optical. When it is dark or in low light conditions, the reflective studs will automatically light up in flashing mode, creating a continuous guide strip on the road surface. Thanks to that, vehicle drivers can easily recognize route directions, especially at curved, out-of-sight locations or when traveling in heavy rain and fog - factors that increase the risk of traffic insecurity on mountainous mountain passes. Proposed addition of 5 standard national highways expresswayReviewing the roadmap to upgrade expressway routes with phased investment Pasting reflective paper on foggy roads The application of active lighting technology is expected to contribute to improving visibility, helping drivers handle situations promptly, thereby minimizing the risk of traffic accidents. Mr. Dinh Trung Thanh, Director of Road Management Area I, said that after the end of the pilot period, the unit will coordinate with relevant agencies to organize an assessment. comprehensively evaluate the effectiveness of the system on many criteria such as navigation ability, level of support for traffic participants, equipment durability as well as operational efficiency in real conditions. The evaluation results will be an important basis to consider the possibility of replicating the model on road sections with similar conditions. This is not the first time the Vietnam Road Administration has boldly applied new technological solutions to improve traffic safety. Previously, the unit coordinated with 3M Vietnam Co., Ltd. to pilot the installation of the 3M(tm) Stamark(tm) Tapes 380 AW reflective road marking system on Highway 6. The continuous research and testing of modern traffic equipment and materials shows the innovation orientation in the management and maintenance of road infrastructure of the Vietnam Road Department. Through the application of technology, the management agency hopes to gradually modernize the traffic signaling system, improve the level of safety on national highways, especially in mountainous and steep mountainous areas with a high risk of traffic accidents.
