Raster maps are widely available in the everyday life, and can contain a huge amount of information of any kind using labels, pictograms, or color code e.g. But due to those overlapping features, it’s not an easy task to extract roads from those maps. Many methods use user input to achieve this goal. In this paper we focus on an automated method to extract roads by using color segmentation and ...

In vision navigation tasks, the road segmentation is a useful method. Usually, roads can be detected using image segmentation and related image process methods. However such methods always rely on specific road prior knowledge, and they are difficult to be realized in different environments. In this paper the learning classification is proposed. In the learning process the roads of different en...

The ability to follow ill-structured roads, such as footpaths, dirt tracks and corridors, is important for mobile robot navigation. This paper presents a panoramic colour vision based road following system for ill-structured roads. Roads are modeled with rapidly adapting 3D colour histograms and a simple yet generic geometric model. The computational complexity of the geometric model fitting st...

Road extraction from satellite imagery has become a heated research subjects in recent years. It is especially used in the city planning, cartography and to update previously detected roads in Geographic Information Systems (GIS) environment.In this study automated road extraction technique is applied to four different satellite images (SPOT, IKONOS, QUICKBIRD, ASTER) with different resolutions...

Arc routing problems arise, for example, when roads require treatment or customers must be served who are located along roads. So practical examples include the routing of people or vehicles for postal deliveries, meter reading and winter gritting, where the roads need to be treated with salt or some other agent to prevent the surface becoming icy. An arc routing problem is represented by a gra...

More than 60% of accidents in Iran occur within 30 kilometers of cities entrance roads. Therefore the number of accidents per kilometer in these regions, in contrast to the other parts of roads is very considerable. The city of Tehran, as the capital of Iran, is the cross point of major arterials of passenger and freight transportation. Thus the evaluation of road safety, entering and exiting t...
