What should technicians consider when installing a new traffic signal?

When installing a new traffic signal, it is crucial to take into account the road width and visibility for drivers. Road width impacts the placement and height of the traffic signal to ensure maximum visibility and effectiveness. Signals need to be positioned where they can easily be seen by all approaching vehicles, which is especially important on wide roads where a driver's line of sight may be obstructed by other vehicles, street furniture, or landscaping.

Moreover, understanding the width of the road assists in determining the appropriate signal type and configuration, such as whether to use multiple signals for different lanes or positions. Proper visibility reinforces the signal's role in managing traffic flow and enhancing safety. This consideration ultimately leads to improved driver response and compliance with traffic regulations.

While aspects like current trends in signal colors, historical data on failures, and costs are relevant to some extent, they do not carry the same immediate impact on the efficacy of the signal installation and the safety of road users as the technical considerations of road width and visibility.
