Inland Waterway Infrastructure Geoinformatics for Risk Assessment and Hazard Mapping

Abstract

Waterway risk assessment system to identify and analyze the waterway hazards and accident risk is recognized as a significant Vessel Traffic System (VTS) technology that can enhance the navigation efficiencies and can reduce the delays and economic losses. This research aims to develop the waterway risk assessment system by integrating technologies of geoinformatics and Augmented Reality (AR) and taking account of IMO requirements, and other relevant guidelines to identify hazard influencing the waterway risk. To demonstrate technology application, the system is successfully conduct risk analysis of waterway accident during 2017 to 2021 and create risk map as the level of risk along Chao Phraya river accidents that jointly caused by human error and environment due to the hazards external to ship including the accident of loss control and the contact with low clearance or short span bridge, a confluence, other dangers near the pier, hidden dangers beneath such as the wooden post and concrete piers. The system can enhance the effectiveness of accident survey and the presentation as visualization and mathematical analysis. In cases where future construction or operation are planned, this assessment system can analyze the waterway risk and create the visualization as risk map and AR images. The forthcoming observed hazards could foresee and even to mitigate in some extent at early stages
