Beware of the likely trade-off between a decrease in the frequency of right-angle crashes and an increase in the frequency of rear-end crashes when considering installation of red-light-cameras.

Red-light running is a significant safety problem in the United States, resulting in approximately 95,000 crashes and 1,000 fatalities annually. One ITS treatment option is to install red-light…
