COMPARATIVE ANALYSIS OF TRAVEL COSTS ON TOLL ROADS AND NON-TOLL ROADS FOR CITY CENTER ACCESS

Abstract

The Mamminasata Urban Area which is centered in Makassar City has a fivesection crossroads at the north gate of the city, where two of which, the Sutami toll and Perintis Kemerdekaan non-toll road sections lead to the city center while the gate is accessed by 18 districts and all provinces in Sulawesi. As alternative roads, the two is generally described as follows: The distance of the gate to the city by the toll road is 17 km while that of by Jalan Perintis Kemerdekaan is 24 Km or 7 km longer than the toll road. The toll road is smooth during the day while the Perintis Kemerdekaan non-toll road section is congested at the peak hours in the morning, afternoon and evening with the potential resulting in far different costs and travel time. The results of the survey indicate 2: 5 in average ratio suggesting that 5 vehicles enter the city center through Perintis Kemerdekaan Non-Toll Road while 2 vehicles opt for Sutami Toll Road. This study was aimed at (1) comparing the Vehicle Operating Costs (VOC) from and to the city center through toll roads or non-toll roads, and (2) analyzing the tendency of the number of travellers to choose through toll roads and non-toll roads based on their orientation to the unit of cost to incur. The mathematical and statistical analysis process was done by considering all components of fixed and variable costs. The analysis also considers the use of the elemental mode of driving mode, the average speed model and the trans-log and Cobb-Douglas models. The results obtained illustrate that the value of vehicle operating costs derived from the two road sections amount to Rp. 25,462 and Rp. 25,500 suggesting insignificant difference. Despite similar travel cost between the two, the toll road is considered more beneficial in terms of the value of time and energy for motorists travelling to the city center of Makassar.
