CMVRTC: Speed Camera Use


Project Goal:

Assess the deterrent effect of highly-visible, CMV-only speed cameras in areas that experience regular high congestion. Further, assess whether this technology should be used to directly populate FMCSA carrier risk profile data.


Some areas do not lend themselves to traditional officer-based enforcement due to congestion or gawker effects. Pulling over a vehicle in these areas can actually increase crashes. To more safely enforce speed limits, a study could be conducted on the use of speed cameras (integrated with USDOT#/LPR reading technology) to capture incidence of CMVs speeding in high crash corridors.


Conduct study to examine high congestion areas to understand when the congestion occurs and if there is an increased crash risk. Select a test area to install speed cameras, record incidence of speeding over a test period, and compare these data to an analogous area and the same period.
