Abstract

Even though special bicycle lanes have been provided, there are still many obstacles that make the provision of these lanes ineffective. Problem parking vehicles in bicycle lanes, as well as the lack of awareness of motorists who use special bicycle lanes, can threaten the safety of their users. Based on the results of the analysis using the IPA (Importance Performance Analysis) method, it is known that the highest service suitability level includes attractive bicycle path designs, harmonious land use and vegetation, and green or white colors on the bicycle lane symbol. The IPA method is divided into four quadrants where quadrant one has low satisfaction while the level of importance is high. There are signs for cyclists, command and prohibition signs, street lighting, backrests that allow bicycles to be locked, cyclists are prioritized over motorists, and height and pavement materials are safe for cyclists, therefore improvements need to be made to create special lanes a bicycle that can bring a sense of security and comfort to the user.

Abstract

Zona Selamat Sekolah (ZoSS) diatur pemerintah untuk menciptakan area aman bagi penyeberang jalan, terutama anak-anak. Pemasangan pita penggaduh (rumble strips) bertujuan meningkatkan kewaspadaan pengemudi dan menurunkan kecepatan kendaraan. Penelitian ini mengevaluasi efektivitas pita penggaduh dalam mengurangi kecepatan kendaraan di SDN Blimbing 04 Malang. Penelitian ini berfokus pada analisis kecepatan kendaraan sebelum dan saat melewati pita penggaduh. Pengumpulan data  menggunakan Speed gun pada tiga hari berbeda yaitu Senin, Rabu, dan Jumat, selama jam masuk sekolah (06.00–08.00 WIB), jam belajar-mengajar (08.00-11.00 WIB) dan jam pulang sekolah (11.00–14.00 WIB). Data diperoleh dari pengukuran kecepatan kendaraan pada jarak 50 meter sebelum dan 50 meter saat melewati pita penggaduh. Analisis data dilakukan dengan menghitung rata-rata kecepatan kendaraan sebelum dan sesudah melewati pita penggaduh. Hasil dari analisis menunjukkan penurunan kecepatan signifikan setelah melewati pita penggaduh yaitu berkisar di antara 12-22% untuk kendaraan bermotor, 7-25% untuk kendaraan ringan, dan 7-19% untuk kendaraan berat. Kesimpulannya, pemasangan pita penggaduh di ZoSS efektif menurunkan kecepatan kendaraan dan meningkatkan keselamatan siswa.
