by New Traffic Lights Confuse Drivers in Massachusetts
New pedestrian hybrid traffic lights have appeared on Massachusetts roads, causing confusion among drivers. Research shows that many do not understand how to properly respond to their signals.
Five Phases of Light Signals
These devices have five different operating modes: off state, flashing yellow, steady yellow, steady red, and flashing red. Unlike conventional traffic lights, which have only three colors, such a variety of signals disorients drivers.
Varied Driver Reactions
A study by the University of Massachusetts Amherst revealed alarming statistics: nearly 25% of drivers run a steady red signal, and when it flashes, this figure increases to 65%. On the other hand, 9% of drivers stop when the lights are off, 19% stop for flashing yellow, and 30% stop for steady yellow, even though stopping in such cases is not required.
Impact of Location
Driver reactions depend on the type of road. On four-lane highways, there are fewer unnecessary stops but more red-light running. At crossings near railway trails, the situation is opposite – drivers stop unnecessarily more often, likely due to the expectation of pedestrians and cyclists.
Researchers question the advisability of using such traffic lights in places with a steady flow of pedestrians but believe that over time drivers will get used to the new rules.
The implementation of new technologies is always accompanied by an adaptation period. Similar systems are already used in other states, demonstrating improved safety after drivers mastered their operation. Perhaps to accelerate this process in Massachusetts, it is worth considering information campaigns or temporary installation of additional explanatory signs. The experience of other regions indicates that such problems disappear over time, and safety at crossings significantly improves.
