The routes of some buses will be changed from 15^th August by shortening their routes. This will solve some issues, for example: a number of buses, traveling in the same direction will be eliminated; bus racing, and also traffic jams will decrease. In other words, people who go to the suburbs will need to change buses. In this connection, the organizers are planning to fix the bus- passing as if for one single journey. Last year, a ten-day day trial period was conducted to study the feasibility.
