TINGKAT KESELAMATAN PENYEBERANGAN MENGGUNAKAN PEDESTRIAN RISK INDEX (PRI) DI JALAN AH. NASUTION KOTA METRO

Introduction

Tingkat keselamatan penyeberangan menggunakan pedestrian risk index (pri) di jalan ah. Nasution kota metro. Penelitian menganalisis keselamatan penyeberangan pejalan kaki di Jalan AH Nasution, Kota Metro, menggunakan Pedestrian Risk Index (PRI). Temukan risiko tertinggi dan perbandingan keamanan tunggal vs kelompok.

Abstract

Ruas Jalan AH Nasution merupakan salah satu ruas jalan yang berada di kota Metro. Jalan ini memiliki tipe 2/2 UD dan merupakan jalan arteri, penghubung antara Kota Metro dengan Kabupetan Lampung Timur dan Lampung Tengah. Penelitian ini bertujuan untuk menganalisis tingkat keselamatan penyeberangan pejalan kaki di Jalan AH Nasution Kota Metro dengan menggunakan metode Pedestrian Risk Index (PRI). Survei dilakukan secara langsung selama tujuh hari pada pagi, siang dan sore hari untuk memperoleh data primer seperti waktu tempuh kendaraan dan pejalan kaki, jarak konflik serta jenis penyeberangan. Penelitian dilakukan dengan observasi langsung terhadap penyeberangan pejalan kaki dan kendaraan yang melintas, dengan membagi waktu (pagi, siang, sore) dan jenis penyeberangan (tunggal dan kelompok). Pengolahan data dilakukan dengan menghitung nilai TTCv (Time to Collision of Vehicle), TTCp (Time to Collision of Pedestrian), Ts (Time to Stop), dan Vimpact (kecepatan tabrakan) sebagai dasar perhitungan PRI. Hasil penelitian menunjukan bahwa nilai Pedestrian Risk Index (PRI) tertinggi berdasarkan waktu penyeberangan terjadi pada hari Kamis pagi sebesar 1372.49, siang sebesar 960.30 dan sore sebesar 1085.55. Sementara itu, penyeberangan tunggal tertinggi terjadi pada hari Kamis dengan PRI sebesar 2327.35 dan penyeberangan berkelompok tertinggi juga pada hari Kamis dengan PRI sebesar 529.79. Penyeberangan kelompok jauh lebih aman dibandingkan penyeberangan tunggal

Review

This paper presents a focused and timely analysis of pedestrian crossing safety on an arterial road in Metro City, Indonesia, utilizing the Pedestrian Risk Index (PRI) method. The research objective is clear, and the methodology involving direct observation over seven days across various times (morning, noon, afternoon) and categorizing crossing types (single and group) demonstrates a commendable effort in data collection. The systematic application of the PRI method, based on parameters like Time to Collision (TTCv, TTCp), Time to Stop (Ts), and Impact Velocity (Vimpact), establishes a robust approach to quantify risk. The findings effectively highlight specific periods and types of crossings associated with the highest pedestrian risk, particularly noting higher risks on Thursdays and for single crossings, providing valuable data for targeted safety interventions. While the study's methodological approach is sound, the abstract could benefit from a few elaborations. A brief conceptual explanation of the PRI, perhaps outlining what different value ranges signify in terms of safety levels, would enhance its interpretability for readers less familiar with the index. The consistent identification of Thursday as the day with the highest risk across different time slots is a significant finding that warrants further exploration regarding potential underlying factors such as specific traffic volumes, pedestrian activity peaks, or other contextual variables. Similarly, the conclusion that "group crossing is much safer than single crossing" is impactful, but the abstract does not delve into potential reasons for this observation, such as increased visibility, collective decision-making, or driver behavior, which would enrich the discussion. Overall, this research makes a valuable contribution to the understanding of pedestrian safety in urban environments, specifically within the Indonesian context. The systematic application of the PRI method yields actionable insights that can inform urban planning and traffic management strategies in Metro City. The study is well-executed and relevant to current transportation safety concerns. I recommend this paper for publication with *minor revisions* to elaborate on the interpretation of PRI values, discuss potential reasons behind the observed patterns (e.g., Thursday's heightened risk, safety of group crossings), and briefly mention potential policy implications stemming from the findings.
