Evaluasi Geometri Jalan Menggunakan Unmanned Aerial Vehicle (UAV) pada Jalan Lingkar Dramaga Bogor

Abstract

Di Indonesia umumnya evaluasi geometri jalan dilakukan dengan cara konvensional seperti menggunakan theodolite atau total station. Oleh karena itu, penelitian ini bertujuan untuk melakukan evaluasi kondisi eksisting geometri jalan menggunakan UAV serta menganalisis ketelitian fotogrametri. Lokasi yang diambil dalam penelitian ini bertempat di Jalan Lingkar Dramaga. Evaluasi dilakukan terhadap alinyemen horizontal dan alinyemen vertikal jalan. Alinyemen horizontal yang dievaluasi berupa sudut belokan, radius belokan, panjang belokan, dan sisipan antar dua tikungan. Evaluasi alinyemen vertikal berupa panjang lengkung dan kelandaian jalan. Hasil uji akurasi berdasarkan kondisi eksisting jalan sebesar 99.2% untuk orthophoto tanpa koreksi dan 99.6% untuk orthophoto terkoreksi ground control point. Hasil orthophoto termasuk kedalam peta ketelitian horizontal kelas 3. Berdasarkan hasil evaluasi terhadap kondisi eksisting jalan, alinyemen horizontal jalan telah memenuhi SNI T-14-2004 sedangkan pada alinyemen vertikal terdapat nilai kelandaian yang melebihi pada segmen A1-A2 sehingga dilakukan rekomendasi perbaikan berupa penambahan elevasi sebesar 0.50 m pada STA 0+390. Penambahan elevasi dapat berupa penambahan lapisan perkerasan.

in indonesia, road geometry evaluating generally is using a conventional method like theodolite or total station. therefore, in this research purposed to evaluate existing condition of road geometry by using uav and to analyze accuracy from fotogrametri. the location taken in this research on Lingkar Dramaga road Bogor. Evaluate on horizontal alignment and vertical alignment roadway. Horizontal alinyemen evaluated in the form of turn angle, turn radius, turn length, and straight inserts between two bends. The vertical alinyemen evaluated are the curved length and slope of the road. Accuracy test results based on existing road conditions were 99.2% for orthophoto without correction and 99.6% for orthophoto with correction ground control point. The orthophoto results are included in the class 3 horizontal precision map. Based on the results of the evaluation of the condition of existing roads, the horizontal alignment of the road has appropriate with SNI T-14-2004 while on vertical alignment there is a value of the slope that exceeds the on segments A1-A2 that is made recommendations for improvement in the form of the addition of elevation of 0.50 m at STA 0+390. The addition of elevation road can be pavement road.
