Effectiveness and Criticism
EMAS has helped LTA to detect road traffic accidents, vehicle breakdowns, and other incidents. By June 2004, LTA had removed conventional SOS telephones from all Singapore expressways (except the CTE tunnels), citing the effectiveness of EMAS and the widespread use of mobile phones as reasons. LTA reassured motorists without mobile phones that they would not be stranded without help in case of a breakdown, as the expressways are patrolled by EMAS recovery teams in two trucks every two hours.
However, the system has been panned by its critics who denounce it as a waste of money, with messages being couched in "unintelligible" abbreviations. For example, "Please" is shortened to "PLS" in the first picture of this article.

Famous quotes containing the word criticism:
“A bad short story or novel or poem leaves one comparatively calm because it does not exist, unless it gets a fake prestige through being mistaken for good work. It is essentially negative, it is something that has not come through. But over bad criticism one has a sense of real calamity.”
—Rebecca West (1892–1983)
