T total cost of moving goods by truck over a highway system involves two basic compon~nts: -the public costs associated with construction and maintenance of the road network, and the privately financed costs of acquiring, operating, and maintaining a fleet of trucks. These publicly and privately financed costs are directly linked in many ways. For instance, the more trucks there are, the more w...

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 ...

Pavement cracks are important information for evaluating the road condition and conducting the necessary road maintenance. In this paper, we develop CrackTree, a fully-automatic method to detect cracks from pavement images. In practice, crack detection is a very challenging problem because of (1) low contrast between cracks and the surrounding pavement, (2) intensity inhomogeneity along the cra...

—Continued on Pg. 2 The new Preservation Group (PG) experiment will provide answers for cash-strapped state and local agencies that need cost-effective ways to maintain existing asphalt roadways. Budgets are tight, but agencies still have the same task: keeping aging pavements in good condition for the driving public. When applied at the right time, pavement preservation treatments, such as chi...

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction, operation, management and economic efficiency of the Indiana transportation infrastructure.
