Miscalculations on traffic flow were to blame for chronic congestion around Times Square, officials admitted yesterday. Steps would be taken over the next two years to ease the situation, the Transport Department said yesterday. Measures will also be taken to create better access for emergency vehicles. Department senior engineer Chiu Tat-fun said congestion in the area was caused by the miscalculation of expected traffic flow when Times Square opened. 'Since its opening, Times Square has been so successful that it has become one of Hong Kong's shopping landmarks,' he said. 'I believe it is right to say that the traffic volume might have been underestimated from the outset.' The proposed remedies, which will cost about $3 million, involve installing three sets of traffic lights, changing the operation of five others and redirecting traffic. Chief engineer Kwan Chi-fai said: 'The delay time for vehicles travelling from Leighton Road to Canal Road West during peak hours in 2006 will be cut from the current 11.5 minutes to two minutes.' At peak times about 2,000 vehicles an hour travel on both Leighton Road and Morrison Hill Road, according to officials.
