Monitoring and Advisory System
If you have been
driving towards and along the major expressways,
you would have noticed the electronic signboards
providing traffic information.
Launched on 21 Mar
98 on the Central Expressway (CTE), the
Expressway Monitoring and Advisory System (EMAS)
has been extended to cover most of the major
expressways since then.
EMAS is the mechanism utilised by
the Land Transport Authority to manage traffic on
expressways. It is a state-of-the-art system
incorporated with sophisticated technology to
monitor traffic conditions on the expressways,
providing motorists with up-to-date traffic
information that would help ensure a safe and
stress-free drive along the expressways.
cameras pick up adverse traffic conditions and
transmit the information to the operators manning
the 24-hour Control Centre for further action.
There are two kinds of cameras. The detection
cameras act as traffic sensors to pick up unusual
traffic flow that is caused by accidents,
congestion and vehicle breakdowns and
subsequently sends an automatic alert to the
staff at Control Centre. The operators will then
make use of the surveillance cameras, which act
as remote eyes to zoom in on these conditions.
Motorists are given advance warnings on these
adverse road conditions through electronic
signboards and via radio announcements and TV
In the meantime,
EMAS recovery crew would have been dispatched to
reach the affected areas within 15-minutes, to
tow the stalled vehicles to the nearest
designated car parks and assist in managing
traffic. There are also SOS phones, placed along
the expressways for motorists in distress to get
help from the Control Centre.

the next issue of The Highway, when we tell you
what the various symbols used in EMAS means.
