The Cost and Maintenance of Electrifying Intersections

The electrification of an intersection can be expensive. Wiring costs can range from $3 to $100 per foot, depending on the requirements. Rearranging the intersection and dealing with pedestrian push buttons adds to the cost. Maintenance and repair are also necessary. Traffic signal technicians have seen it all, from hurricanes to rats damaging the wiring. One major innovation in traffic lights is the transition from incandescent to LED bulbs, which has reduced electricity bills for many cities. Although LED bulbs are more expensive upfront, they have a longer lifespan. Are there any other downsides to using LED bulbs?
