DEEPWATER TURBIDITY CURRENT DYNAMICS: INCEPTION, EROSION AND DEPOSITION

Part 1 Topics of Interest to State DOT Safety Engineers

There are several ways in which road network can be deficient and hence lead to potential safety problems. Highlighting geometric deficiencies is an important exercise because it identifies road sections that are potentially a safety problem, rather than just revealing sections that have previously had safety problem (using traditional crash analysis). We are now able to offer the service, which will help full to identify the accident risk locations and the main reasons for the accident along your highway road network. This study will help to assist effective and efficient network maintenance and management.
