Analisa Perlambatan Kecepatan Kendaraan Di Penghujung Traffic Light Perempatan Jalan Dengan Menggunakan Persamaan Differensial Derajad Satu. (Studi Kasus Ruas Jalan Ir. H. Soekarno–Kertajaya Indah Surabaya)

Abstract

One of the parameters used to monitor the characteristics of the highway is the speed of the vehicle. Vehicle speed factor plays an important role in the description of the dynamics of traffic flow of a highway, where with high vehicle speed can be predicted high traffic flow on the road. The aims of the research is to find a model equation that can describe the speed of the vehicle at one time in the selected arterial road such as the road Ir.H Soekarno which has a high volume of vehicles. The resulting equation model can be utilized for vehicle analysis at stopping point at the zebra cross or intersection with traffic light. The method used in this study based on vehicle speed data input and applied to the calculation with differential equations of degree 1 and obtained a form of mathematical model. The mathematical equations obtained from this research on segment of the Ir.H.Soekarno road are St = 50,92.e ^ (- 0.0684.t) where St is the vehicle speed in km / h and t is the travel time in hours.
