Trish - As you comment on government policies, this is poor management strategies show only based on election. But they did not consider the fact that effected parties due to tax variance. Specially vehicle importers and sales will be in real trouble due these fluctuations. I have a doubt that this may increase again after the election.
For heavy traffic in city area can be reduce by implement below suggestions,
1. Limit personal vehicle entrance to city- ( Need to make proper car parking around city and luxury/semi luxury public transportation should arrange from park to city- This can be a big earning for government if corruption wasn't there).
2. Increase no.of trains and buses including facilities.
3. Promote private companies (inside the city)to supply transport facility to there employees.
4. Acknowledge drivers to avoid traffic creation due to poor driving styles. specially three wheel drivers
