Haphazard parking of vehicles in the vicinity of schools caused rush-hour traffic jams that almost paralysed the city on Tuesday.
There are 36 schools along the congested main thoroughfares in the city and only a few have adequate space to accommodate vehicles bringing students to school.
On Wednesday, at least 34 school authorities, quoting student safety, did not allow any vehicle, other than their school buses, entry into their grounds.
From 8 a.m., hundreds of vehicles, of parents escorting their wards to school, clogged the roads leading to the institutions. They parked on either side of narrow roads and on footpaths, bringing traffic to a standstill and impeding even pedestrian movement. The police could do little and they were under orders not to play spoilsport by fining parents on school-reopening day.
Traffic enforcers said the city was likely to see a rash of similar traffic holdups on Wednesday, when scores of lower and upper kindergarten schools and crèches reopen for the new academic year.
They have declared the Vanchiyoor-General Hospital road and the Devaswom Board-Christ Nagar School road a one-way between 8 a.m. and 10.30 a.m. on all school days till the traffic situation normalises.
A social organisation is scheduled to hold a march on the arterial M.G. Road at 3 p.m., the time when some schools close for the day. A senior official said the long-term solution to the problem was to stagger school timings so that they would not conflict office timings and business hours.
