A new freeway traffic forecasting system is set to be introduced next year to provide motorists more precise and real-time information on travel conditions, the National Freeway Bureau said.
The forecasts, which will be incorporated into the newly launched electronic toll system, will be able to analyze quickly the traffic flow on freeways and give drivers a heads-up, bureau Deputy Director-General Wu Mu-fu (吳木富) said.
The freeway forecast will be more accurate than a weather forecast, Wu said.
The new toll collection system, which charges motorists based on the distance traveled instead of tollbooth collection points they pass through, was launched in December last year. The use of tollbooths was replaced with an automated system that scans each vehicle’s electronic toll collection (ETC) tag when it enters and exits Freeway No. 1, No. 3 or No. 5.
With the help of the system, the bureau can quickly process the more than 13 million transactions — or vehicles registered on the freeways — each day to predict traffic conditions on weekdays and weekends, Wu said.
For example, the system will be able to tell the bureau how many vehicles are on which section of the freeways at any given time. It can then relay the information to motorists, Wu said, adding that parts of the project is still under development.
Since vehicles will be examined based on the codes assigned to them — instead of their license plates — motorists need not be concerned about privacy leaks, Wu said.
The original match-up details will be used by the company operating the electronic toll collection system, and the data the bureau receives will be encoded, Wu added.
Any third party trying to access that information needs to apply for it, he said, without elaborating.
Weather conditions across Taiwan are expected to remain stable today, but cloudy to rainy skies are expected from tomorrow onward due to increasing moisture in the atmosphere, according to the Central Weather Administration (CWA). Daytime highs today are expected to hit 25-27°C in western Taiwan and 22-24°C in the eastern counties of Yilan, Hualien, and Taitung, data on the CWA website indicated. After sunset, temperatures could drop to 16-17°C in most parts of Taiwan. For tomorrow, precipitation is likely in northern Taiwan as a cloud system moves in from China. Daytime temperatures are expected to hover around 25°C, the CWA said. Starting Monday, areas
A Taiwanese software developer has created a generative artificial intelligence (AI) model to help people use AI without exposing sensitive data, project head Huang Chung-hsiao (黃崇校) said yesterday. Huang, a 55-year-old coder leading a US-based team, said that concerns over data privacy and security in popular generative AIs such as ChatGPT and DeepSeek motivated him to develop a personal AI assistant named “Mei.” One of the biggest security flaws with cloud-based algorithms is that users are required to hand over personal information to access the service, giving developers the opportunity to mine user data, he said. For this reason, many government agencies and
The National Fire Agency on Thursday said a series of drills simulating a magnitude 8.5 earthquake would be held in September to enhance the government’s emergency response capabilities. Since earthquakes cannot be predicted, only by continuously promoting disaster prevention measures could Taiwan enhance its resilience to earthquakes, agency Director-General Hsiao Huan-chang (蕭煥章) said in a news release. The exercises would be held to mark annual National Disaster Prevention Day on Sept. 21, the aim of which is to test Taiwan’s preparedness and improve its earthquake resilience in case of a major temblor, Hsiao said. As part of those drills, an earthquake alert would
STRICTER ENFORCEMENT: Taipei authorities warned against drunk cycling after a sharp rise in riding under the influence, urging greater public awareness of its illegality Taipei authorities have issued a public warning urging people not to ride bicycles after consuming alcohol, following a sharp rise in riding under the influence (DUI) cases involving bicycles. Five hundred and seven people were charged with DUI last year while riding YouBikes, personal bicycles, or other self-propelled two-wheelers — a fourfold increase from the previous year, data released by the Taipei Police Department’s Traffic Division showed. Of these, 33 cases were considered severe enough to be prosecuted under “offenses against public safety,” the data showed. Under the Road Traffic Management and Penalty Act (道路交通管理處罰條例), bicycles — including YouBikes and other
