The Metropolitan Police Department (MDP) traffic safety experts have made decisions on the 6 dozen locations based on "...incidents of speeding-related fatalities and crashes, proximity to school zones and other places where children or other vulnerable populations may be present, and known sites of chronic speeding". I'm starting to notice these all around town and am thankful I'm not a driver.
If you are a city or community making the decision to install a solar speed signs, here are four solar energy considerations:
- Latitude (sun exposure)
- Traffic volume
- Access to grid energy
- Size of sign/number of LEDs
