Abstract

This research is on the Jalan Raya Cengkeh that is one of 4/2 D type and have a purpose to know percent correlation analysis of heavy vehicles, streams and vehicles velocity toward noise level in 4/2 street on the road of Cengkeh. So, this research hoping became some consider for the people in chart to solving traffic noise level problem. From the preliminary survey known that the middle point is the best point to doing the research in next survey. From the survey result known that noise level pressure value (Lp)= 56,4 until 100,9 dB(A) and noise equivalent value (Leq)= 70,78 until 95,13 dB(A). In another heavy vehicle percent (P)= 4,76 until 28,57 %, vehicles stream (Q)= 1020 until 2640 vehicle/hour and means vehicles velocity (V)= 33,33 until 46,92 km/hour. Regression Analysis between P with Leq has polinom relation with R2= 0,2995 that mean has a weak correlation, But between Q with Leq has polinom relation with R2= 0,6693 that mean has a strong correlation, and between V with Leq has polinom relation with R2= 0,5123 and also mean has a strong correlation. The choice mathematic model is multilinier logaritmic with two variables are stream vehicles (Q), means velocity vehicles (V), the form is Y = -89,579 + 17,353 Ln (Q) + 12,579 Ln (V), R2 = 0,688, with 1020 < Q < 2640 and 33,33 < V < 46,92 Keywords: Noise level pressure value, equivalent noise level value, streams, vehicles speed
