This project is concerned with exploitation and maintenance of geoinformation inventories for storing elements of traffic infrastructure. The main motivation for developing such systems is to provide a direct and comprehensive insight into the prescribed state of the road. This capability is subsequently applied for streamlining various kinds of safety inspections of a public road network in operation. Geoinformation technology for traffic applications is in the long-term focus of the Institute of transport and communications, which jointly funded this project together with the Croatian science foundation. The most important objective of road safety inspections concerns assessing the compliance of traffic control infrastructure. The inspections are designed to detect anomalies such as broken, covered, worn-out or stollen traffic signs, and erased or incorrectly painted road surface markings. Today, this task is typically performed by experts which perform visual inspection of geo-referenced video and compare it with the reference state stored in the corresponding part of a geoinformation inventory.
Short description of the task performed by Croatian partner
The main goal of this project is to streamline the procedures which form the basis for road safety inspection. We attempted to achieve this goal by researching ways to relax the dependencies on trained human experts. In particular we wished to find out whether reliable detection and recognition of different kinds of traffic signs and surface markings could be performed automatically by computer vision techniques. It is fairly obvious that such facility would lower the costs of assessing the roads for which there already exist corresponding geoinformation inventories. However, we also note that this functionality would considerably simplify the mapping of new roads by creating new geoinformation inventories from acquired georeferenced video.
