How can ATSPMs be better?
They’re hardware dependent, so the data they’re using isn't accurate.
We worked with UDOT to do one of the largest studies of detector data ever, and found their detectors are only 27.6% accurate
. In the same study, we found their ATSPMs missed 82.8%
of split failures,
and were more likely
to do so as control delay rose.
They only show operations metrics, and only at a phase level. ATSPMs don’t aggregate their phase metrics to show you what’s happening at the intersection or network level. And they don’t show you how these operations issues are impacting safety, mobility, equity, and the environment. Instead of solving problems, you’re analyzing your data for these answers.
