9. Delays to bus and rail journeys ( Tables 12 and 13)
9.1
Table 12 provides estimates of delays to bus and rail journeys. From April 2003, for each bus or rail journey made, the interviewer asked "was this part of your trip delayed?" and, for those who said that it was, the interviewer asked "why was your journey delayed?" and "how much time do you think was lost because of this?" Approximately 8% of bus journeys and 7% of rail journeys between April and December 2003 were said to be delayed. 4% of bus or rail journeys were delayed by about 5 or 10 minutes, and 3% for about 15 minutes or longer. Most of the figures in
Tables 12 and
13 are based on only a small number of journeys, so are subject to large sampling errors.
9.2 11% of bus or rail journeys which started between 7:00 and 9:30 a.m. on a weekday suffered delays, as did 15% of such journeys started between 4:30 and 6:29 p.m. A slightly higher proportion of journeys appeared to suffer delays on Fridays and Sundays, but these figures are based on small samples, so could be subject to large errors.
9.3
Table 13 shows that 46% of delays to bus journeys were said to be caused by congestion on the roads, and 28% by the bus arriving late. No other named reason accounted for more than 5% of delays.
