Lights system can hurry fire engines
I refer to the letter from R. E. J. Bunker headlined, 'Override query' (South China Morning Post, January 6) regarding emergency vehicles being delayed by traffic lights. Mr Bunker said that 'in many cities overseas, traffic lights can be overriden from the fire stations to clear a path for fire engines', and he asked if such a measure had been considered in Hong Kong.
Under the Area Traffic Control system, there exist facilities called 'Hurry Call' and 'Green Wave', that can control the traffic signals for emergency vehicles so they can pass through junctions.
The 'Hurry Call' facility controls the traffic signal at the nearest junction to the local fire station and it is activated by the local fire station.
The 'Green Wave' facility can generate a series of green traffic signals for emergency vehicles, so they can get through junctions at pre-determined routes and it is activated by the Fire Services Department's headquarters. According to our records, there are 16 pre-determined routes for Central Fire Station.
