Accessibility and Connectivity of Connecting Road Probolinggo-Lumajang

Abstract

The Probolinggo-Lumajang area is an access road that is one of the development priorities. Therefore, it is necessary to study the connectivity of the road infrastructure. Improvements in connectivity are carried out to facilitate the movement of people who will cross the area and also increase the potential in the area. With the improvement in access, developments in other fields in the region can therefore increase. The main purpose of this study is to analyze the accessibility and connectivity of the road that connects Probolinggo and Lumajang districts. This study used the accessibility index analysis and connectivity index analysis. The results showed that the accessibility index has a medium density category. The medium density category has a minimum accessibility index value of 0.50, so the accessibility index value of the Probolinggo-Lumajang Connecting District is categorized as not appropriate (low) with the existing parameters of 0.02 or less than 0.50. The connectivity index value in each link between the connecting sub-districts has 2 classifications, namely low and high. The results of this study contributed to the Governments of Lumajang Regency and Probolinggo Regency in preparing directions to improve the accessibility of the Lumajang-Probolinggo road section by offering a solution to adding 2 new road alignments, namely Tiris Road to Ranuyoso Road and Kuripan Road, Bantaran Road to Ranuyoso Road with road lengths of 14.08 km and 9.50 km respectively. The addition of a new road alignment was carried out as an alternative for drivers to be able to go directly to the primary collector road by avoiding congestion caused by market activities.
