The data collected from eTags — an electronic device used to pay toll fees on the nation’s freeways — has helped the freeway authority forecast the travel times and regulate traffic using more effective measures, according to the National Freeway Bureau.
The electronic toll collection system for all freeways was launched on Dec. 30, 2013.
There are 319 toll fee-collecting gantries on freeways and more than 8.9 billion transactions were recorded as of last month, Bureau Deputy Director-General Wu Mu-fu (吳木富) said.
Wu said that this data has helped the bureau map patterns of freeway users, adding that it can be further analyzed and calculated to enhance the efficiency of freeway traffic management and research for better techniques to regulate it.
By analyzing the routes of drivers, the bureau knows which freeway ramps should be closed when there is traffic congestion, Wu said, adding that the data can also help the bureau determine toll fees for the launch of the differential toll fee scheme. The scheme is to charge peak-hour toll fees on certain freeway sections, Wu said.
Based on the information collected, the bureau can also forecast traffic situations at a specific time, Wu said.
The bureau tried using the data to forecast the travel time between Taipei and Kaohsiung, as well as between Nangang (南港) and Suao (蘇澳), at different hours of day on some of the nation’s major holidays, including the Dragon Boat Festival, Moon Festival and Double Ten National Day, Wu said.
The proposed use of eTags, operated by Far Eastern Electronic Toll Collection Co, to pay for parking fees, still needs to secure the approval of lawmakers, Wu said.
“Legislators fear the use of eTags for parking would lead to job losses for those tending parking lots, just as freeway toll fee collectors lost their jobs when the government launched the electronic toll collection system,” Wu said.
“They want us to study the business potential and the problems of producing invoices if people are able to pay their parking fees using eTags,” Wu added.
To allay lawmakers’ doubts, Wu said that allowing people to pay parking fees using eTags would not cause job losses, but only make toll collectors’ jobs easier, as staff could scan the bar code on the eTags, rather than having to key in license-plate numbers.
The company would also be able to provide invoices for transactions paid by eTag, Wu said.
Alain Robert, known as the "French Spider-Man," praised Alex Honnold as exceptionally well-prepared after the US climber completed a free solo ascent of Taipei 101 yesterday. Robert said Honnold's ascent of the 508m-tall skyscraper in just more than one-and-a-half hours without using safety ropes or equipment was a remarkable achievement. "This is my life," he said in an interview conducted in French, adding that he liked the feeling of being "on the edge of danger." The 63-year-old Frenchman climbed Taipei 101 using ropes in December 2004, taking about four hours to reach the top. On a one-to-10 scale of difficulty, Robert said Taipei 101
Taiwanese and US defense groups are collaborating to introduce deployable, semi-autonomous manufacturing systems for drones and components in a boost to the nation’s supply chain resilience. Taiwan’s G-Tech Optroelectronics Corp subsidiary GTOC and the US’ Aerkomm Inc on Friday announced an agreement with fellow US-based Firestorm Lab to adopt the latter’s xCell, a technology featuring 3D printers fitted in 6.1m container units. The systems enable aerial platforms and parts to be produced in high volumes from dispersed nodes capable of rapid redeployment, to minimize the risk of enemy strikes and to meet field requirements, they said. Firestorm chief technology officer Ian Muceus said
MORE FALL: An investigation into one of Xi’s key cronies, part of a broader ‘anti-corruption’ drive, indicates that he might have a deep distrust in the military, an expert said China’s latest military purge underscores systemic risks in its shift from collective leadership to sole rule under Chinese President Xi Jinping (習近平), and could disrupt its chain of command and military capabilities, a national security official said yesterday. If decisionmaking within the Chinese Communist Party has become “irrational” under one-man rule, the Taiwan Strait and the regional situation must be approached with extreme caution, given unforeseen risks, they added. The anonymous official made the remarks as China’s Central Military Commission Vice Chairman Zhang Youxia (張又俠) and Joint Staff Department Chief of Staff Liu Zhenli (劉振立) were reportedly being investigated for suspected “serious
American climber Alex Honnold is to attempt a free climb of Taipei 101 today at 9am, with traffic closures around the skyscraper. To accommodate the climb attempt and filming, the Taipei Department of Transportation said traffic controls would be enforced around the Taipei 101 area. If weather conditions delay the climb, the restrictions would be pushed back to tomorrow. Traffic controls would be in place today from 7am to 11am around the Taipei 101 area, the department said. Songzhi Road would be fully closed in both directions between Songlian Road and Xinyi Road Sec 5, it said, adding that bidirectional traffic controls would
