The provided bar chart illustrates the number of incidents and injuries per 100 million passenger miles travelled on five different types of public transportation in 2002.
Looking from an overall perspective, it is readily apparent that the largest number of incidents and injuries occurred on demand-response vehicles. By contrast, commuter rail services recorded by far the lowest figures.
A total of 225 incidents and 173 injuries per 100 million passenger miles travelled took place on demand-response vehicles. The second highest category, bus services accounted for figures three times lower than demand-response figures. There were 76 incidents and 66 injuries.
The number of incidents on light rail services equalled the figure recorded for busses, but there were fewer injuries, 39. Heavy rail trains saw a lower number of such events than light rail services, with 51 incidents and 35 injuries. Commuter rail trains recorded the fewest problems, with only 20 incidents and 17 injuries.
