In recent years, the Hong Kong government has been promoting the application of technology to improve departmental services and efficiency. Among them, the Office of the Government Chief Information Officer (OGCIO) and the Transport Department have developed a traffic forecasting system that uses big data to estimate road conditions in the next 15 to 90 minutes. Hong Kong eMobility" to check the route to avoid traffic jams.
The EPD also uses deep learning to analyze voiceprint and image data to develop illegally modified vehicle detectors at a cost as low as 1% of traditional equipment.
According to the OGCIO, the new-generation government cloud platform can shorten the development time for departments, and has supported 15 big data analysis projects and more than 350 digital government services.
According to Chen Xizhen, Senior Engineer (Smart Mobility Department) of the Transport Department, the traffic data analysis system launched in June this year integrates real-time vehicle speed, road accident information, past traffic records, real-time and forecast weather data, etc. It can also predict the road speed and travel time in the next 15-90 minutes, and can further analyze the impact of traffic accidents and bad weather.
Predict road conditions within 15-90 minutes to help citizens plan routes to avoid traffic jams
In terms of application, the current forecast data has been used for internal traffic management and bus diversion, etc. Citizens can also search for routes in the "HKeMobility" mobile application. After selecting the departure time, the system will automatically predict the corresponding travel time; Published in an open data format for use by developers, the logistics industry, etc.

At present, the Transport Department's intelligent transport system has installed traffic detectors on major arterial roads to collect traffic data. Among them, the Bluetooth function has caused privacy concerns, but the detectors only cover 25% of the road sections in Hong Kong. The Department said at the time that a privacy risk assessment had been conducted , the data will be automatically deleted after calculation.
In addition to using detector data, the newly launched traffic prediction system also uses the arrival time of buses and green minibuses to estimate the speed of road sections, which is sufficient to cover 70% of the road sections in Hong Kong.
"Governments use open data"
Zhao Shanheng, Chief System Manager (Data Analysis) of the OGCIO, said that the government has been actively promoting open data in recent years, and "all the government uses open data". For example, in this project, data on buses and minibuses were used to improve traffic.
He also pointed out that the new-generation government cloud platform can shorten the development time for departments by 3-4 months, and can promote more innovative applications. A total of 15 big data analysis projects and more than 350 digital government services have been supported.

Voiceprint analysis of illegally modified "dead throat" vehicles has an accuracy rate of 90%
Another example is the low-cost illegally modified vehicle detection device developed by the EPA using artificial intelligence technology.
Wu Wenting, system manager (data analysis) of the OGCIO, introduced that the system equipment includes a radio, a high-speed camera that captures road surfaces and license plates, etc., and uses the deep learning function of the government cloud platform to analyze road noise voiceprint data to detect illegal modifications.” "Dead Air" vehicles have an accuracy of 90%, and each cost is only about 10,000 yuan, which is 1% of the traditional equipment.
However, the project is still in the experimental stage and involves law enforcement.
New technology costs only one percent of traditional instruments
Big data analysis can also be applied in the field of urban safety. For example, the Civil Engineering and Development Department uses machine learning to assess the risk of landslides, and cooperate with the professional knowledge of engineers to properly arrange slope maintenance.
Innovative technologies can also improve the efficiency of resource utilization. In recent years, many government departments have launched chatbots, which are integrated by the OGCIO into a shareable basic chatbot system, including a shared natural language processing engine, knowledge base, etc., to reduce development costs.
The Greater Bay Area’s innovation and technology ratio and Hong Kong’s R&D spending as a percentage of GDP are second in the data. Sun Dong: The government has measures to support the transformation of scientific research.
