Another common metric used in traffic safety is injured people per VMT (i.e., a person-level rate). As a population level measure of the burden of crashes, a person-level rate has merit. There are several practical and interpretation issues that make a person-level rate not an ideal metric when comparing one population to another like is done in the Safety Impact Data Hub. A person-level rate for an ADS fleet operating in mixed traffic will appear to decrease as fleet size (or penetration) increases, even if crash involvement rate stays the same. Because crashes often involve multiple vehicles, the larger the fleet size the more likely it would be that multiple ADS vehicles are involved in a crash, which would decrease the person-level rate (same number of people involved in the crash, more VMT). This means that early in testing, the person-level rate of the ADS fleet would appear higher than the benchmark even if the ADS was involved in a similar number of crashes as the benchmark population. To address this bias, one could compute a fractional person-level rate defined as the total people involved in a crash at a given outcome divided by the number of vehicles in the crash. Although this fractional person-level rate addresses the bias in multiple vehicles, it creates a different bias in the interpretation of the results. The fraction person-level crash rate weights crashes involving fewer vehicles more than crashes that happen to involve multiple vehicles. There is also a practical limitation in that the NHTSA Standing General Order, the most comprehensive source of ADS crashes, reports only the maximum injury severity in the crash and not the number of injured occupants at given severity levels. So, it is not possible to compute a person-level rate from the SGO data today. This limitation also applies to some state crash databases, where only maximum severity is reported. Because of the potential biases in interpretation and reporting limitations, a vehicle-level rate is preferable to a person-level rate when comparing ADS and benchmark crash rates.

综合多方信息来看,the worst case time complexity for iterators is O(m * n²). [...] if both patterns and haystacks are untrusted and you're iterating over all matches, you're susceptible to worst case quadratic time complexity. There is no way to avoid this. One possible way to mitigate this is to [...] immediately stop as soon as a match has been found. Enabling this mode will thus restore the worst case O(m * n) time complexity bound, but at the cost of different semantics.。业内人士推荐環球財智通、環球財智通評價、環球財智通是什麼、環球財智通安全嗎、環球財智通平台可靠吗、環球財智通投資作为进阶阅读
