This research evaluates public street lighting with case studies on Jalan Dr. Setiabudhi Bandung, 4,980 kilometers (km) from the start of the Lembang direction to the Cihampelas direction. Tests have been carried out by measuring illuminance values (lux) on 114 light points on the road. Most lights are assumed to use typical SOX with 135 watts of power, voltage range of 220-240 volts (v), frequency of 50-60 hertz (Hz). Measurements and calculations was done with result the height from the base of the pole to the lamp varies from 7.04 meters (m) to 10.51 m with an average of 9.8 m. Observations and measurements along the road also recorded as many as 29 lights were off, 15 lights were slightly covered by trees, and 23 lights that were not blocked directly illuminated the road. There are a total of 51 of 114 lighting poles whose luminance values are below the Standar Nasional Indonesia (SNI). The total 63 points of the luminaires that meet SNI, as many as 50 points of luminance value are greater than 15 lux. The shortest distance between light poles is 22.8 m, the longest is 273 m with a mean of 40.9 m. Evaluation shows both in terms of illuminance, distance between poles and power and the type of lamp used still has the opportunity to be redesigned to be more efficient. Redesign is done using dialux evo more efficiently. Opportunity optimization by implementing the Particle Swarm Optimization (PSO) algorithm was proposed in this research.
