Abstract

The Lhokseumawe City Bypass Road is one of the national arterial routes that plays a strategic role as an alternative corridor connecting the Medan–Banda Aceh road. The development of activities along this road segment, such as educational areas, shops, restaurants, and religious facilities, has triggered an increase in roadside activities. These conditions generate side frictions in the form of on-street parking, pedestrian crossing activities, and vehicles entering and exiting adjacent areas, which have the potential to reduce traffic performance. This study aims to analyze the effect of side frictions on the capacity and level of service of the Lhokseumawe City Bypass Road. The research method uses a descriptive quantitative approach through field surveys conducted for seven consecutive days during morning to afternoon peak hours. The collected data include road geometric conditions, traffic volume, and the types and frequency of side frictions. The analysis is based on the Indonesian Road Capacity Guidelines (PKJI) 2014 to determine road capacity, degree of saturation, and level of service. The results show that side frictions have a significant effect on road segment performance, indicated by a reduction in capacity of approximately 20–35%. This impact causes the level of service to decline from category B (good) to category C (moderate). These findings emphasize the importance of managing roadside activities through parking management, control of access points, and increased public awareness in using road space in an orderly manner to maintain traffic performance.

Abstract

Flooding is a recurring hydrometeorological disaster in watershed areas characterized by diverse physical environmental conditions, including Bantaeng Regency, South Sulawesi, Indonesia. Variations in topography from upstream to downstream areas, slope gradient, soil type, geological conditions, rainfall, and land use patterns significantly influence flood vulnerability and risk. This study aims to spatially model integrated flood vulnerability and risk based on physical environmental and watershed characteristics in Bantaeng Regency. The research employs a Geographic Information System (GIS)-based approach using weighted overlay analysis of key physical parameters, including rainfall, slope, soil type, geology, elevation, and land use. Flood hazard and vulnerability were analyzed separately and subsequently integrated to produce flood risk maps. The results indicate that high to very high flood risk zones are predominantly concentrated in lowland and downstream watershed areas, particularly in regions with gentle slopes, fine-textured soils, and intensive built-up land use. Furthermore, the spatial analysis reveals that several road networks and public facilities are located within high-risk flood zones, potentially disrupting socio-economic activities. This study contributes to the development of integrated GIS-based flood risk modeling and provides essential insights to support regional planning, watershed management, and flood mitigation strategies at the local scale.
