Performance Assessment Measure That Indicates Geometry Sufficiency of State Highways: Volume I—Project Scoring and Network Screening
Indiana Department of Transportation - Joint Transportation Research Program
The Indiana Department of Transportation (INDOT) selects projects for implementation by taking into account several criteria related to cross-section, alignment and safety to evaluate various geometry improvements to be carried out as a part of projects. The existing practice uses an intuitive point allocation method to score these individual categories. The current study proposes a methodology to evaluate these projects considering the safety and mobility impacts of the improvements which lie…
The Indiana Department of Transportation (INDOT) selects projects for implementation by taking into account several criteria related to cross-section, alignment and safety to evaluate various geometry improvements to be carried out as a part of projects. The existing practice uses an intuitive point allocation method to score these individual categories. The current study proposes a methodology to evaluate these projects considering the safety and mobility impacts of the improvements which lie in the scope of each project. This methodology is also used to screen roads based on existing geometry deficiencies with respect to a desirable design standard. The road screening process and the project evaluation process form two steps that support the asset management process. The road screening process helps in filtering road segments based on geometry deficiencies and identifies the least adequate road segments. Projects may be further developed with estimated improvements to be carried out on such segments using detailed information regarding these improvements.
As part of the study, we have also investigated feasible ways of extracting additional elements from available datasets to support asset management in Indiana. We have looked into available data sources for their suitability. We have combined the use of orthophotos, LiDAR point clouds, digital elevation and surface models to identify remote sensing methods that are capable of extracting the required features efficiently. We propose a framework for determining the paved surface, average grade, embankment slopes, extracting the obstructions near the traveled way like trees and man-made structures.Other authorsSee publication -

The road screening process helps in filtering road segments based on geometry deficiencies and identifies the least adequate road segments. Projects may be further developed with estimated improvements to be carried out on such segments using detailed information regarding these improvements. The asset management components discussed here rely on the evaluation of safety and mobility benefits corresponding to geometry changes. To develop an up-to-date method, the safety performance functions used in this method have been calibrated based on the latest crash data available for 2009-2011. Safety performance functions have been developed for rural two-lane, rural multi-lane, urban two-lane and urban multi-lane roads in the state of Indiana. The crash modification factors derived from these safety performance functions and speed adjustments from earlier studies, supplemented with data available in Highway Capacity Manual are used to calculate the safety and mobility benefits.

Monitoring of River Center Line and Width-A Study on River Brahmaputra
Journal of the Indian Society of Remote Sensing
Monitoring of river width and center-line is one of the most important activities in river engineering. Changes in the width and center line can be attributed to several reasons and monitoring these changes can be conveniently achieved with the aid of remote sensing images. In this study, digital image processing techniques have been implemented using the image processing tool-box available in MATLAB for studying temporal variations of width and center-line of the river Brahmaputra in its 300…
Monitoring of river width and center-line is one of the most important activities in river engineering. Changes in the width and center line can be attributed to several reasons and monitoring these changes can be conveniently achieved with the aid of remote sensing images. In this study, digital image processing techniques have been implemented using the image processing tool-box available in MATLAB for studying temporal variations of width and center-line of the river Brahmaputra in its 300 Km reach in the state of Assam, India. The current study uses relatively high resolution imageries acquired from the LANDSAT series of satellites. Apart from the LANDSAT imageries, the low resolution imageries acquired by MODIS program is also used in order to see the variation in the obtained results. The evaluation of the results shows that the digital image processing technique is very handy and can be applied to obtain the center-line and width of a river. The evaluation also shows that the low resolution image can also be used for obtaining center-line of a river. However, it may give erroneous result when width of the river is narrow or very large.
