![]() ![]() One of the examples in energy efficiency practice is car-free streets. Energy consumption can be shown by number of vehicles and number of vehicles can be shown by sound level comparison or sound level mapping. Sound level mapping is a graphic representation of the sound level distribution existing in a given region, for a defined period. The higher sound level indicates more vehicle pass through an area. Number of vehicles and limited street capacities create traffic jam frequently. During a traffic jam, vehicle burn fuel but not moving and cause bad effect to environment. Sound level mapping is needed to know how big the effect of sound level to environment quality. Optimizing environment quality can be made by giving suitable recommendation based on sound level mapping. In this research, sound level mapping is conducted using Geographic Information System (GIS). ![]() GIS integrates five key components: hardware, software, data, people and methods. Universitas Gadjah Mada is selected as the research location due to the large amount of vehicles used by students and the areas intersect with public spaces. Data were collected in five areas which have intersections with public spaces such as hospital, shopping center, worship place, food court, and main road. ![]() Measurement points will be given for each area. ![]()
