The Service Level of the National Road Section from Mamuju to Tampa Padang Airport, West Sulawesi

Abstract

The road section connecting Mamuju City with Tampa Padang Airport is a vital transportation route in West Sulawesi Province. This section becomes a logistics route for goods and passengers when the national road from Majene is blocked by landslides, as well as connecting Mamuju City with Tampa Padang Airport and Belangbelang Harbor. In line with economic growth, this road section is suspected of experiencing excess capacity. Moreover, West Sulawesi is a buffer zone for the National Capital (IKN) of the Archipelago in East Kalimantan. This research aims to analyze traffic density so that it influences the level of road service. This type of research is descriptive with a qualitative approach using the 1997 Indonesian Road Capacity Manual Method (MKJI). The results of the research state that the capacity and service level index (ITP) at the three monitoring points vary. Point 1 and point 2 with road type 2/2 UD have a capacity of 2,970 pcu/hour, while point 3 with type 4/2 D has a capacity of 3,069 pcu/hour. Volume Capacity Ratio (VCR) at sampling point 1 with an average VCR value of 0.30 (VCR < 1) at level of service 'B'. This means that traffic flow conditions are stable, operating speed is starting to be limited by other vehicles and obstacles are starting to be felt by surrounding vehicles. The average VCR value at sampling point 2 is 0.18 at level of service 'A' (VCR < 1), meaning that in free flow conditions at high speed, the driver can choose the desired speed without obstacles. The average VCR value at sampling point 3 with a two-way divided road type (4/2 D) has a value of 0.07 at level 'A' (VCR < 1), meaning that in free flow conditions at high speed, the driver can choose the appropriate speed. desired without any obstacles
