The chart below shows numbers of incidents and injuries per 100 million passenger miles travelled (PMT) by transportation type in 2002.

The bar chart compares the number of incidents and injuries for every 100 million passenger miles travelled by five different means of transport in 2002 (this just restates the prompt).

It is clear that (delete) most of the (delete) incidents and injuries for every 100 million passenger miles travelled (delete) happened when people choosing (verb form error) the (delete) demand-response vehicles. By contrast, commuter rail services reported the lowest figure (of incidences and injuries). Overall speaking (delete), the number of (delete) incidents were all higher than the number of injuries (unclear).

Demand response vehicles recorded the highest number of both incidents and injuries per 100 million miles travelled in 2002, which was 225 and 173 respectively. However, the figures for bus only counted around one third of those for demand response.

The other three types of rail services had fewer problems. Among these three types, the commuter rail service was the safest choice of vehicle, which only counted 20 in incidents and 17 in injuries. The heavy rail service had high level of risks, for it had figures of 51 and 35 for incidents injuries respectively. The light rail service contained the highest level of risks among the three types of rail, but was still much safer than the other two kinds of vehicles mentioned above.
