Prospect of Rolling Highway System Implementation on Makassar–Parepare Freight Transportation Route Based on Operator Perception

Goods transportation on the Trans Sulawesi road is dominated by truck transportation which causes problems including high operational costs, road damage due to over-dimension overload (ODOL) vehicles, and increased carbon emissions. Therefore, more efficient and sustainable alternative transportation modes are needed, one of which is the Rolling Highway (ROLA) system. This study aims to analyze the potential for ROLA implementation based on truck operators' perceptions of operational costs, travel time, flexibility, security and safety, policy support, ease of loading and unloading, and environmental impacts. The study used perception analysis and multiple linear regression, from truck operators on the Makassar-Parepare route. The results showed that a 20% reduction in operating costs and up to 120 minutes of travel time could increase operators' willingness to shift to the ROLA system. However, flexibility and ease of loading and unloading are still major constraints that need to be addressed. In addition, the implementation of ROLA has the potential to reduce road damage, lower carbon emissions, and improve the efficiency of logistics distribution. To implement this policy, the government needs to develop economic incentives (operational subsidies) and accelerate investment in ROLA -supporting infrastructure.
