I am travelling around the city with red bus and I can say that from my experience of travel that it is cheap from any other mean of transport .it is organised by govt. Which is cheap and available in all around the city for different routes and is expanding in other areas also.one can go cash less if he/she make a red bus card from the ISBT which cost different for different categories of people for student it is 350/- for 1st time and an monthly recharge of 300/- for whole the month of 30 days .after recharging the card you can travel anywhere in red bus of 1 month .by making card there is no tension of change(khula paisa) , .the busses are available after every 15 minute of interval at every bus stop in all the routes .
