Abstract

The growth in the number of motor vehicles and community activities in Yogyakarta City put great pressure on the transportation system, which has an impact on the increasing number of traffic accidents. The high accident rate shows the need to identify vulnerable locations as a basis for the preparation of prevention strategies. This study aims to identify accident-prone locations in the city of Yogyakarta through a spatial approach and formulate handling recommendations based on the results of road safety inspections. The methods used include spatial analysis using the ArcMap software-based Geographic Information System (GIS), with three main approaches, namely spatial autocorrelation analysis (Moran's I), hotspot analysis (Getis-Ord Gi), and density estimation (Kernel Density Estimation). Accident data was obtained from the Yogyakarta City Resort Police and weighted using the Equivalent Accident Number (EAN) method. The results of the analysis identified 16 hotspot points with a 99% confidence level, as well as four priority locations that require immediate handling, namely Jalan Kyai Mojo, Jalan Menteri Supeno, Jalan P. Diponegoro, and Jalan Brigjen Katamso. The results of road safety inspections show that there are problems such as damage to the road surface, markings that are not clearly visible, lack of traffic signs, and misuse of sidewalks. Handling recommendations include repairing road infrastructure, repainting markings, adding signs and crossing facilities, and restoring sidewalk functions for pedestrians. It is hoped that the implementation of this recommendation can reduce the accident rate and significantly improve traffic safety in the city of Yogyakarta.

Abstract

The growth of tourism in Yogyakarta City has led to an increase in the need for tourist terminal facilities that are able to regulate the movement of tourist buses in a more orderly, efficient, and safe manner, especially in the strategic area of Gumaton (Tugu-Malioboro-Kraton) which has the highest rate of visits in the city. This research aims to determine the most ideal location for the development of tourist terminals through spatial analysis approaches, field surveys, SWOT analysis, and Analytic Hierarchy Process (AHP) methods. Primary data was obtained through surveys of bus movements at five main intersections, physical observation of road sections, and distribution of questionnaires to tourists, bus drivers, the community, business actors, and government stakeholders. Meanwhile, secondary data was obtained from the Yogyakarta City RTRW, tourist visit statistics, and transportation regulations. The AHP assessment criteria include accessibility, RTRW suitability, transportation network integration, land availability and technical feasibility, traffic and safety impact, and environmental sustainability. The AHP results showed that the Giwangan Terminal obtained the highest score of 59.75%, followed by the Ngabean crime scene at 27.28%, Jalan Margo Utomo at 7.20%, and Jalan Jenderal Sudirman at 5.78%, with a Consistency Ratio (CR) value of 0.033 which indicates the consistency of a valid matrix. This finding is strengthened by SWOT results which show that Giwangan has significant advantages in terms of land availability, accessibility, and spatial suitability. Thus, Giwangan Terminal is designated as the most feasible location for the development of Yogyakarta City tourist terminals in the short and long term.
