/PRZWT/Xiamen, April 16, 2024 - On April 10, the 14th China Road Traffic Safety Products Expo and Public Security Traffic Police Equipment Exhibition (referred to as the "Traffic Fair") kicked off in Xiamen. As a leading enterprise in smart transportation, Hisense Network Technology made a major appearance, setting up a scene-based display area with the theme of "intelligent channel and comfortable travel" on the spot, innovatively created intelligent voice interactive experience, newly released road traffic safety risk prevention and control system, as well as leading industry products and solutions such as signal control and command and dispatch, making Hisense once again a star exhibition area of the Trade Fair.
Big model technology blessing to create a new experience of intelligent voice interaction
Driven by new technologies, the integration of large-scale models and intelligent voice interaction has brought unprecedented convenience and possibility to traffic management. Hisense takes cloud brain technology as the core and combines large-scale traffic models to build three core capabilities: big data, video AI, and scene-based, to comprehensively improve the efficiency of traffic operations.
In particular, the application of large-scale model technology has turned traditional system control into natural voice interaction. Hisense engineers demonstrated on the spot that when asked "how the city's traffic operation is", the Hisense leadership cockpit can accurately identify the semantics and give a quick answer, showing the questioner the traffic congestion situation and the police on duty and law enforcement. Not only that, but the Hisense system can also drill layer by layer and close the loop after finding anomalies, upgrading a picture of "static" data into an interactive dynamic cockpit.
Automatic identification of 38 types of safety hazards, closed-loop management to maintain safety red lines
"The road ahead is prone to accidents, please drive with caution." I believe many people have heard such a reminder during driving. The brief words are not only a reminder to drivers to drive safely, but also a microcosm of Hisense's escort for road traffic safety.
In response to the problems of unclear base numbers, unknown hidden dangers, and ineffective rectification in the management of traffic risk hazards, Hisense's road traffic safety risk prevention and control system has achieved a breakthrough. First of all, to achieve the aggregation and management of the full amount of data, from the case, transcripts, etc. to correct and complete nearly 100 basic information, data sorting is accurate and fast. For example, the accuracy rate of accident address relocation has reached more than 95%. In the past, it took 4 people and more than half a year to sort out the data. Now it can be done in 1 person and 1 month.
At the same time, a hidden danger mining technique was developed to automatically identify 38 types of hidden dangers such as high-risk enterprises and high-risk drivers. A closed-loop management system for rectification effect evaluation was established, so that "if there are hidden dangers, there must be countermeasures, if there are countermeasures, there must be implementation, and if there is implementation, there must be results". After being applied in a city, the number of accidents and the number of deaths decreased year-on-year, effectively supporting the accident prevention and control work.
Nine types of scene-based command mode, "Everyone is an excellent commander"
Traffic congestion is a problem in the process of urban development. Hisense starts from traffic control and signal tuning to open up traffic jams and dredge traffic arteries, providing citizens with a smooth travel experience and providing solid support for social and economic development.
In terms of traffic control command, Hisense has created a new model of "scene-based command" to solve the problems of slow incident recognition, slow handling, and strong experience dependence in traditional traffic management. By sorting out more than 100 sub-categories of command scenarios in 9 categories such as morning and evening peaks, large-scale events, and bad weather, experience is solidified, and the command threshold is lowered, so that everyone is an excellent commander.
Taking the marathon guarantee as an example, Hisense innovates "segmented sealing and dynamic solution" to minimize the sealing and control time, and uses the system to automatically monitor the alarm situation to detect the surrounding congestion, accidents and other anomalies in time, and reduce the traffic impact. In the Jinan Marathon guarantee, the sealing and control time is shortened from 9 hours to 5.5 hours, and the abnormal event detection time is shortened to 1 minute.
The first regional green wave automatic tuning, allowing more vehicles to go green all the way
The complex road network and the sharp increase in the number of private cars in China have brought great challenges to travel. The traditional way of manually adjusting the signal lights is slow and the effect is not sustainable. Hisense pioneered the automatic tuning of regional green waves, using the accessed data to automatically find out which line and what time period is suitable for running green waves, and achieved "green wave into a network". The regional efficiency is increased by more than 20%, and the number of stops is reduced from 10 to 2 times, allowing more cars to enjoy the smooth experience of green lights all the way.
Zhangzhou, Fujian is a typical city that applies Hisense signal tuning. By continuously deepening the application of intelligent transportation systems, Zhangzhou has built a total of 321 signal control intersections and 321 networked intersections, with a networking rate of 100%; 54 green wave coordinated sections, 264 coordinated intersections, and a coordination rate of 82%. Under the background that Zhangzhou's car ownership exceeded 1.50 million and increased by 11.5% year-on-year, the average congestion delay index in 2023 was 1.32, a year-on-year decrease of 0.75%.
As a leading enterprise in smart transportation, Hisense will continue to deepen cutting-edge technologies, empower the refined management of urban transportation, create a convenient and safe travel environment for citizens, and lead the future development direction of the industry.
