NDOT engineer cites ~8 mph average reduction after speed cushions in program data
Summary
NDOT staff presented follow-up data from 38 projects showing average speeds fell from about 32.7 mph to 24.4 mph after vertical measures; higher-percentile drivers showed even bigger drops, the presenter said.
Chase Fuqua, an engineer with Findlayhorn working on behalf of NDOT, highlighted empirical results from follow-up monitoring of prior traffic-calming projects.
"So that 32.7 average before going to a 24.4 after," Fuqua said when summarizing averages across about 38 sites where cushions or speed tables had been installed, adding that the 95th-percentile speeds fell from 42.3 to 32.5 in the same comparison. Fuqua used the data to argue the program's vertical measures produce measurable speed reductions.
Fuqua framed those results as part of a data-driven prioritization process used to pick West Town Drive for the spring 2026 round; he said the program combines speed and volume measures with walkability and crash history when scoring applications.
