Operations Management for Improve Traffic Performance in Bandung City with DMAIC Six Sigma Method

Abstract

Congestion is a common issue in major cities. It causes driver fatigue, vehicle emissions, environmental pollution, and noise. Controlling pollution conditions in the city is very important for urban transport organizations such as the Ministry of Transport of the Republic of Indonesia to make traffic decisions. In this journal, we suggest a technique focused on DMAIC to increase the efficiency of urban traffic. The recommend procedure consists of three steps. In Stage 1, a survey was conducted to collect traffic congestion data in Bandung City. In Step 2, the DMAIC technique is used to evaluate the survey data obtained in Stage 1. Methods employed include the causal or Ishikawa diagram, factor analysis, six sigma control diagrams (individual and multivariate), and Pareto analysis. In Stage 3, we made suggestions to reduce traffic congestion and increase the efficiency of transport services in the region, based on Stage 1 and 2. The proposed work can be applied in practice to handling traffic congestion circumstances in the area application of the potential methodology to the City of Bandung.
