PUBLIC TRANSPORT TIMING: CAUSES OF DELAY ARISING DURING BUS JOURNEYS

Bus movement times were studied on three routes. An attempt was made to analyse delays at traffic-light-controlled intersections in the city centre along these routes. In the study it was concluded that: delay times are seldom more than 20 per cent of the mean travel time and on average vary from 4 to 10 per cent of the mean travel time; about 80 per cent of the delays are caused by traffic-light-controlled intersections; delays due to congestion caused by other vehicles are a substantial minor factor; boarding time per passenger on one-man-operated buses is twice that on two-man operations; the timetable allowance for inbound journeys is not realistic compared with the time allowed for outbound journeys; in this case, very little time would be saved by rerouteing of the services; the average running speeds of the buses varied between 25 and 50 km per hour, depending on the route, the average travel speeds being higher than the scheduled speeds; there was very little variation in mean travel time between that on average weekdays and on Saturdays. /TRRL/
