Simulation modelling of traffic flows in the central business district using PTV vissim in Pekanbaru, Indonesia

Abstract

The state of art simulation modelling in managing traffic flow within a busy central business district (CBD) is demonstrated in this article. The objectives of this article were to; identify the existing condition of the street V/C ratios within the CBD area, and to develop various simulations modelling. The development of microscopic traffic simulations encompassing 5 streets within the CBD area in Pekanbaru, Indonesia using the PTV Vissim application was performed as a case study. The existing conditions of these 5 streets were very busy (Level of Service C and D) with on-street parking and on-street traders (vendors) along the streets. Several simulations model based on 4 traffic management approaches were applied; (i) controlling on street traders (vendors) activity, (ii) controlling parking lots, and (iii) changing the on-street parking angle and (iv) combination of these approaches. The simulation results have indicated that the optimum simulation modelling in managing CBD traffic flow within these 5 streets was conducted by managing the on-street parking angle at the position of 300 as well as controlling on street traders activity. Hence, by conducting simulations using this application improved the streets Level of services (LOS) within this CBD area from D (0,75 < 0.74).
