When it comes to speed, delay and congestion usually get more attention than the flip-side problem of excessive speed. Under statute, for example, the federal government requires agencies to track speed reliability and delay. There is no similar requirement for tracking excessive speed, even though the data set provided for monitoring slow traffic could be used for fast traffic as well. However, the National Transportation Safety Board’s new 2019-2020 Most Wanted List, which it identifies as its “premier advocacy tool” in advancing transportation safety improvements, includes highway speed management in its Top 10 list.
