... Lighting master plans can include lighting curfews and emerging electronic monitoring and control systems. The benefits of a master plan include the following: • Improving safety through maximizing resources, • Improving traffic flow, • Improving driver comfort/confidence, • Reflecting a consistent image of the local culture and tastes, • Identifying the nature of the site (e.g., residential versus restaurant row)

... Lighting control networks can be either wireless or hardwired. Field devices always include controllers, which necessarily consume data to implement some control function according to internal programming and may also include sensors, which Source: California Lighting Technology Center, University of California, Davis.
