Analysis Of The Suitability Of C-Band Radar-Based Rainfall Data With Rain Gauge Stations In The Upper Ciliwung Watershed, Indonesia, Daffa Aliyo Ghinannafsi, Evi Anggraheni, Muhammad Rizal, Peter Hartono Halim

CSID Journal of Infrastructure Development

Accurate rainfall estimation is essential for hydrological modelling and flood risk management, particularly in mountainous watersheds where rain gauge coverage is limited. This study evaluated the performance of a calibration correction method for C-Band radar rainfall estimates in the Upper Ciliwung Watershed using data from five rain gauge stations and 100 rainfall events. Data quality was verified through outlier and consistency tests before applying a daily calibration correction factor derived from gauge observations. Radar performance was evaluated using the Nash-Sutcliffe Efficiency (NSE), Percent Bias (PBias), and Root Mean Square Error (RMSE). Before correction, radar estimates substantially overestimated rainfall, with NSE …

Development Of An Adaptive Pelican Crossing Model Using Fuzzy Logic In Mixed Traffic Conditions, Manazil Adam, Andyka Kusuma, R. Jachrizal Sumabrata

Smart City

Traffic management at at-grade pedestrian crossing facilities (pelican crossings) in highly populated areas, such as the Universitas Indonesia Station, faces significant inefficiency challenges. During peak hours, the fixed-time system is frequently disabled and replaced with subjective manual control by security personnel, thereby triggering irregular stop-and-go cycles and a high accumulation of vehicle delays. This study aims to develop a hybrid adaptive control model integrating Computer Vision, Genetic Algorithm (GA), and Fuzzy Logic to optimize intersection performance under mixed traffic conditions. The research methodology begins with the extraction of traffic and pedestrian characteristic data, calculated manually through recorded field observations. This …

Road Safety Assessment For Accident And Non-Accident Cases Supporting Sustainable Development Goals 2030, Brian Nararya Nugraha, Sekar Warangi Nurcahyati, Hizkia Adhikaratma, Martha Leni Siregar

Journal of Environmental Science and Sustainable Development

Halving the number of global deaths and injuries from road traffic accidents is one target of the Sustainable Development Goals 2030, which is still a challenging problem in Indonesia. However, the majority of research on this topic uses accident-based methods, which limits the safety analysis. Two road safety assessment methods are used to close the gap, with the addition of non-accident-based methods such as Road Safety Audits (RSA). The Margonda Raya Road, which is categorised as a traffic accident blackspot, was selected for the case study. For this, a field survey of the road segment is carried out. To minimise …

Analysis Of The Relationship Between Speed Consistency And Traffic Accident Probability (On The Mojokerto-Surabaya Toll Road), Riki Risfiandi, Martha Leni Siregar

Smart City

Vehicle speed consistency plays a crucial role in maintaining traffic safety, with speed limits set to reduce accident fatalities. While the direct impact of speed limits on vehicle speed is minimal, their implementation significantly influences driver behavior, with about 85% of drivers complying with speed limits. However, variables such as traffic volume, weather conditions, and travel urgency often cause drivers to be inconsistent in adhering to these limits, increasing accident risk. On the Mojokerto-Surabaya toll road, data from Traffic Corps and Jasa Marga recorded 193 accidents with 101 fatalities from 2018 to August 2023, mostly caused by driver behavior such …
