Pavement Evaluation and Pavement Maintenance

IN T R O D U C T IO N T he In d iana D epartm ent of Highways has em barked upon es­ tab lish ing a Pavem ent M anagem ent System (PMS). As a p a rt of this, the Jo in t H ighway R esearch Project has had an on-going research p ro ­ ject for the past several years dealing with m ethods of m easuring pave­ m ent condition in Ind iana .

Neural Networks in Stereo Vision Evaluation of Road Pavement Condition

This study presents the method for the measurement of road pavement condition based on a stereo vision method of surface representation. The road is represented as a set of points in 3D space. Problems of stereo vision analysis regarding the ambiguity of matching points images, discontinuity depth for neighboring objects registered on the images, etc. were redacted by used neural networks. The ...

Motorists’ Evaluation of Road Maintenance Management

The road network is extremely valuable. Road Administrations are expected to invest maintenance funding in a way that returns maximum benefit to road users. Cost-benefit analysis is one method to ensure that an adequate return in terms of benefits results from committing expenditure. Today, cost-benefit calculations are frequently used as a base for decision making of investments. The surges fo...

Scenario-Based Modeling in Industrial Information Systems

This manuscript addresses the creation of scenario-based models to reason about the behavior of existing industrial information systems. In our approach the system behavior is modeled in two steps that gradually introduce detail and formality. This manuscript addresses the first step, where text-based descriptions, in the form of structured rules, are used to specify how the system is or should...
