The bar chart represents the figures of how many times accidents and injuries occurred per 100 million PMT in 2002 in terms of the transportation categories.
Overall, it is evident that the frequencies of injuries taking place were considerably lower than that of incidents among all the types. While the demand responses stood out with its predominant high risks, rails remained much lower, among which the commuter rail was the most safety ride.
More than half of the incidents in 2002 involving demand responses, namely 225 times per 100 million PMT. The remaining half of the incidents took place when taking rails and buses. Additionally, travel by light rails and buses shared equally numbers at 76 times a year, following by the heavy rail traffic at approximate 50 times during the seam period. Notably, passengers who chose to take commuter rails were much safety than other types, with merely 20 times incidents recorded.
Conversely, the injuries risky rate was mitigated comparably. Although taking demand responses still represented the dominant position, the frequency of accidents reduced by almost 50 times (173 times). This similar decrease could be seen in other four transportation types. While the injures in light rail systems were
considerably reduced by around 30 times, marginal difference in injury rates of commuter rails could be observed, representing 17 times as the lowest.
