Highway
The urban highway serves high-speed traffic, continuous traffic, long-distance traffic, and large traffic capacity. Routes are characterized by the width of the heart of the road (6–10 lanes), so street lighting ensures navigability, helping the driver quickly and accurately handle situations on the road.
City Highway
The main axis, covered by the urban area, serves high-speed traffic (up to 80 km/h) with urban significance. Connecting large residential centers, large industrial parks, and urban buildings, street lighting ensures navigability, ensures safety for traffic participants, and beautifies the urban landscape at night.
Area level line
Area-level streets are transportation-sensitive areas such as large residential areas and districts. Thus, lighting ensures safety for traffic participants while also beautifying the urban landscape at night.
Internal level line
Internal streets are connections between branches, residential units, industrial parks, and public or commercial sites. Thus, lighting ensures safety for traffic participants while also beautifying the urban landscape at night.
