I took bus 857 to Raffles City on a Sunday morning to meet a friend for breakfast. I took bus 857 back to my home.
I paid attention to the average time taken for each stop, On the way there, the average time was 1.5 minutes per stop as it was a Sunday morning and the traffic was light. On the way back, the average time was 2 minutes per stop.
On both occasions, I ignored the stretch where the bus traveled on the Central Expressway.
I wanted to collect this information to support my concept of changing the bus system to have express and feeder services. The express service stops every 2 km. The intermediate stops can be served by a feeder service. This new structure will reduce the travel time on buses.
