The Congestion Factors of Container Truck Travel from Tanjung Emas Port to the Hinterland Region

Abstract

Semarang Container Terminal or Terminal Petikemas Semarang (TPKS) at Tanjung Emas Port is one of the container terminals in Indonesia with growing container traffic, recorded in 2020 reached 712.062 TEUs. The interaction of the components of the transportation system between ports, road facilities and container trucks needs to be synergized, for the smooth flow of container traffic and avoiding travel obstacles or road congestion. Container movement congestion is the result of an imbalance between traffic volume and road capacity, especially container trucks, resulting in the level of road service which ultimately results in a decrease in vehicle speed. This research aims to find the clarity about the main factors forming congestion based on the dynamics of environmental change, using an analysis of the variables causing congestion based on the results of a survey in 2013 with 30 samplings of container trucks and 60 samplings of container trucks in 2019 on the road from Tanjung Emas Port, Semarang to the hinterland area around Ungaran, Semarang Regency. The analysis was conducted by using descriptive regression method and model testing with Minitab 18 software. It can be explained that the main factors causing congestion that have an impact on decreasing speed affecting the travel time of container trucks are road geometric such as road gradients, vertical alignments, intersection and activity on shoulder.
