Determining of Parking Lot Area Policy Using System Dynamic Simulation Approach

摘要

Parking lot is one of the important public facilities for all people because of its function to accommodate the stopping vehicles. However, because of its limited parking area, a lot of vehicle users park their vehicles at side of the road. It resulted in street problems because the road become narrower and this creates stuck traffic jam. Sleman, one of five districts in Yogyakarta Province, has heavy stuck traffic jam due to the narrow road. The problem arises when many people park their vehicles at the side road. One of the dense parking area in Sleman District is Babarsari Road, Gejayan Road, and road in Ambarukmo areas. Stuck traffic jam get worse due to increasing vehicle numbers and limited parking area available. The increased vehicle numbers are influenced by many dynamic variables. Therefore, an approach to formulate and adopt policy for dynamic parking side area is seriously needed. This research was conducted to analyze the existing parking area width. The purpose of this study is to offer accurate recommendations to improve parking area capacity by using system dynamic simulation approach. The research was startedon understanding the real system in formulating causal loop diagram and stock and flow diagram to understand interactive relationship among variables. Following this matter, two scenarios were made to get recommended policy in order to accommodate side road parking area width to reduce stuck traffic jam. From two proposed scenarios, it was found that the second scenario was the best recommendation with the least error score.
