Architect Arrol Gellner says that traffic engineers use traffic lights far too often when a simple stop sign works better and is much less expensive.
Gellner says that 2-way or 4-way stop signs are "...cheaper, by several magnitudes, than installing a traffic signal, which nowadays costs from $80,000 to $100,000 or more depending on bells and whistles such as crosswalk signals and the like. Add to this the perpetual expense of maintenance and the cost of electricity to power signals 24 hours a day, and you're talking about a serious drain on taxpayer dollars."
