Lornie Road [Towards Upper Thomson]
Posted on Mon, 30 Oct 2017
I was analysing my data when I saw something peculiar; throughout the first 3 weeks of October 2017, there was only 4 instances of traffic congestion and 1 of them, on 18 Oct 9:30am, lasted pretty long at 80 mins as shown below.
I did a search and discovered this article [Source: Channel News Asia].
"The Singapore Civil Defence Force (SCDF) said it received a call for assistance along Lornie Road, towards Upper Thomson, at about 9.18am."
That explains the chart!
