Expressway Monitoring and Advisory System - History

History

The contract for the construction of EMAS was awarded by the LTA to Singapore Technologies Electronics in December 1996. The first phase, implemented only on the Central Expressway, was launched officially on 21 March 1998 by then Minister of State for Communications, John Chen.

The system was further expanded in its second phase to monitor tunnels of the CTE, as well as Ayer Rajah Expressway, East Coast Parkway and Pan Island Expressway. This was implemented by April 2000.

Famous quotes containing the word history:

    A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.
    Aristotle (384–323 B.C.)

    The custard is setting; meanwhile
    I not only have my own history to worry about
    But am forced to fret over insufficient details related to large
    Unfinished concepts that can never bring themselves to the point
    Of being, with or without my help, if any were forthcoming.
    John Ashbery (b. 1927)

    In history as in human life, regret does not bring back a lost moment and a thousand years will not recover something lost in a single hour.
    Stefan Zweig (18811942)
