Network Geographic Information System is a GIS based on Web technical standards and communication protocol of network , a product of Web technology and GIS technology, it is based on Internet / Intranet to provide users with information distributed in space, data sharing, exchange and cooperation. WebGIS make full use of network resources, a large scale to reduce costs and complexity of dealing...

The road pavement condition is a ected by various impacts such as trucks, deicing reagents, base erosion, etc. After some time on the road surface occur defects. Engineers are commonly used to collect pavement surface distress data, during periodic road surveys, but it takes a lot of time and manpower. In this paper, we present our automatic defects detection and classi cation on road pavement ...

Here we establish that equivalent single-axle loads values can be estimated using artificial neural networks without the complex design equality of American Association of State Highway and Transportation Officials (AASHTO). More importantly, we find that the neural network model gives the coefficients to be able to obtain the actual load values using the AASHTO design values. Thus, those desig...

With regard to limits in annual budget for maintenance, inevitably, one must choose prioritized projects to optimize the allocated budget in the network. This paper looks into prioritization based upon models including all effects of important factors such as pavement condition index, road type, traffic volume as well as rehabilitation and maintenance cost. Analytical hierarchy process and fuzz...
