More than half the respondents to a survey said videos should be banned in some areas on Kowloon Motor Bus vehicles. Of the 1,173 people interviewed in the Democratic Party study, 52.5 per cent said television and radio broadcasting should be banned from some areas of the buses. The study did not specify the areas. More than 30 per cent said the volume on the programmes broadcast was too loud. The company introduced its 'Roadshow' service to 1,500 buses in December and it is expected to be available in 2,000 vehicles by the end of the year. Democratic Party transport policy spokesman Andrew Cheng Kar-foo said the party had received complaints from residents in the western and northern New Territories that they were being bombarded by noise.
