Analisis Keselamatan dan Kenyamanan Lalu Lintas terhadap Penggunaan Traffic Light di Simpang Empat Jl. Raden Kusno – Jl. A. Djaelani – Jl. Raden Sujarwo, Kecamatan Mempawah Hilir

Abstract

This research is motivated by the increasing urban activities in Mempawah Hilir District as a Regional Activity Center, which has led to high traffic movement at the intersection of Jl. Raden Kusno – Jl. A. Djaelani – Jl. Raden Sujarwo. The diversity of land use and the meeting of arterial and collector roads create potential traffic conflicts and accident risks. The installation of traffic lights is implemented as a traffic control measure; however, its effectiveness in improving safety and comfort needs further analysis. This study aims to assess traffic safety and comfort conditions after the implementation of traffic lights at the intersection. A quantitative approach was used with primary and secondary data. Primary data were obtained through questionnaires on road users’ perceptions and field observations, while secondary data included traffic accident records from Mempawah Police and spatial development data from Google Earth Pro, Google Maps, Copernicus, and Google Colab. The analysis employed descriptive-comparative, spatial descriptive, and scoring methods. The results show that traffic lights implemented since August 2023 have reduced traffic accidents and improved safety conditions, although not yet optimal compared to the lowest accident rate in 2021. Increased land use activity and traffic volume influence this condition. User perceptions indicate improved comfort internally, but external factors such as road conditions and side obstacles still reduce comfort and safety.
