E Birch wonders why buses are delayed when there is no obvious cause within sight of his bus stop (Letters, August 14). Sadly, there is no cure for a bus held up by unpredictable traffic delays on one part of its cross-city journey that will make it instantly recover its scheduled timing just beyond the blockage.

Our joint investment with Brighton and Hove City Council in a vehicle-tracking system currently being implemented is giving us a better picture of the consequences of such delays so we can take appropriate action that minimises inconvenience.

The new signs being introduced at many bus stops will enable us to provide up-to-the-minute information to waiting passengers.
