Singapore’s public bus operators have been buying new buses and introducing new bus routes. However, bus commuters are as dissatisfied as ever, going by the latest Customer Satisfaction Index of Singapore (CSISG) report on public transport. Public buses' score languished at 60.6, a good way below the wider Transport and Logistics' sector's improved score of 72.7, and Singapore's 2012 national score of 69.9. Institute of Service Excellence at SMU (ISES) Academic Director Dr Marcus Lee said: "Perception is reality. Perhaps bus commuters have not yet experienced the intended improvements with these investments."
