Abstract

Abstract The capacity of the road environment is the number of vehicles that can be allowed to pass a road without crossing environmental quality standards. The study discusses the relationship between the environmental capacity of the road in terms of the impact of noise and air pollution caused by vehicles traveling on the road around the school area, namely Jalan T Panglima Nyak Makam in Banda Aceh. Data is collected using a Sound Level Meter measuring instrument brand Norsonic type 131, and for air pollution Data processing and analysis uses a General Motors prediction model with a real-time recording system. The level of noise and air pollution is greatly influenced by the geometric of the road, the volume and, the speed of the vehicle. The traffic volume that passes on this road is relatively the same between morning and afternoon with an average traffic volume of 486.8 pcu/hour/direction and an average speed of 33.19 km/hour. The capacity of this road is 1455.3 pcu/hour. From the research results obtained Leq values ranged from 72.8 dB (A) - 78.2 dB (A), with an average value of 76.00 dB (A). This Leq value indicates a noise level that has an impact on the community that is greater than 70 dB (A), and is still within the maximum noise threshold of 85 dB (A) and has passed the noise standard in the school area of 55 dB (A), then This road section is no longer feasible for school areas if assessed from the noise that occurs, while for air pollution produces data in the form of the calculation of the highest air pollution estimates on each observation day on Wednesday compared to other observation days at 07.00-08.00 WIB for CO pollutants (LV) 1,301 ppm, CO (HV) 0.016 ppm, NOX 0.096 ppm, and HC 0.063 ppm. This shows that the capacity on Jalan T. Panglima Nyak Makam is still feasible because the DS limit for urban roads is 0.85 and classified as this road is still able to accommodate the traffic volume with the estimated air pollution provided.
It can be concluded that the road section in this school area from noise has passed the threshold but is still acceptable in terms of air pollution.
