Classes in a number of elementary and secondary schools have opened this week, so traffic is beginning to be at bit more unbearable than it already is. Expect it to worsen in the coming weeks once classes resume in different colleges (unless you’re studying in one of those colleges who have recently made a shift in their academic calendar that classes would now begin in July or August…but that’s another story) But there’s something else for the metropolitan commuter to brace for that is certain to make impact on the wallet: a fare hike.
