The report also look at the possiblilty to implement the count-down system in London.  This measure is expected to help clarify the uncertainty that pedestrian face when the ‘black-out’ period appear .

  • Significant findings of the study included:
    • Overall, around half of all pedestrians cross against the red man signal
    • 60 per cent of pedestrians did not correctly understand the purpose of the blackout period
    • 67 per cent of impaired pedestrians interviewed did not understand the blackout period
    • 90 per cent of conflicts at crossings – pedestrian or vehicle braking or changing direction, or physical contact (of which there were zero during the study) – involved a pedestrian crossing during the red man
  • re-timing of the green man invitation to cross period resulted in an increase in vehicle throughput through the junctions of 6.5 per cent.
