The presentation will discuss Q-MOKA, a GIS application developed in collaboration with the Hellenic Ministry of Infrastructure and Transportation to manage and analyze traffic accidents along the Greek Primary and Transeuropean Road Network. Q-MOKA addresses the challenges of the existing Traffic Accident Registry, which lacked geospatial referencing and robust data validation. Built around QGIS and Postgres/PostGIS, Q-MOKA offers several key functionalities: * Network Model: Supports multiple linear referencing systems for accurate accident location representation. * Dual-Carriageway Management: Ensures consistent linear referencing even during network realignments. * Flexible Accident Location: Records accidents by X,Y coordinates or route/offset, maintaining synchronization between the two methods. * Linear and Point Data Management: Allows creation and editing of additional linear and point event data relevant to the Agency (e.g., number of lanes, speed limits). * Geographic Mapping: Provides route-level accident mapping based on the recording service. * Custom QGIS Forms: Facilitates data entry and management through user-friendly forms. The presentation will delve into the technical aspects of Q-MOKA, including its database structure, configuration options, and potential future enhancements. By offering a robust and user-friendly platform for traffic accident management and analysis, Q-MOKA contributes to improved road safety and informed decision-making in Greece.
