The Computer Aided System For Planning Efficient Routes, J. R. Wright
The Computer Aided System For Planning Efficient Routes, J. R. Wright
JTRP Technical Reports
The Indiana Department of Transportation has sponsored the design and implementation of a decision support system for routing highway maintenance vehicles – the Computer Aided System for Planning Efficient Routes (CASPER). Designed for solving multiobjective route design problems, CASPER has been used by agency personnel to design routes for winter maintenance vehicles with significant results: cost savings of more than $9-million to the State of Indiana through more efficient use of materials, equipment, and personnel, while at the same time significant improvement in overall level of network and public service. CASPER integrates 1: an extensive spatial network database (GIS/CAD), 2) …
Use Of Waste Foundry Sand In Highway Construction : Final Report, Sayeed Javed
Use Of Waste Foundry Sand In Highway Construction : Final Report, Sayeed Javed
JTRP Technical Reports
The promulgation of environmental regulations, both at the federal and state level, have resulted in increased control over both the hazardous and nonhazardous wastes generated in the foundry industry. The increased regulation action has in many cases resulted in foundry wastes being disposed in highly engineered and often times costly land disposal facilities. Beneficial reuse represents an alternative to disposal and the associated problems of diminished landfill capacity and increased tipping fees. This study contains: synthesis of all available information and laboratory results for different beneficial uses of waste foundry sand. Among the different beneficial uses, waste foundry sand as …
Estimating Statewide Vehicle Miles Traveled In Indiana : Draft Final Report, Robert Kwasi Kumapley, Jon D. Fricker
Estimating Statewide Vehicle Miles Traveled In Indiana : Draft Final Report, Robert Kwasi Kumapley, Jon D. Fricker
JTRP Technical Reports
Two cross classification models have been developed in this study for use in the estimation of statewide VMT in Indiana. This is to provide INDOT with an independent source of improved statewide VMT estimates based on driver behavior to supplement the estimates obtained from the traffic count based HPMS method. The models are calibrated to produce VMT estimates for all functional classes in the state network, including combined statewide VMT estimates for functional classes that are not part of the state highway system. The results obtained in the model evaluation process indicate that the models are well calibrated. Model-generated VMT …
Implementation Of The Developed Quality Acceptance System For Steel Bridge Painting Construction, Luh M. Chang, Machine Hsie
Implementation Of The Developed Quality Acceptance System For Steel Bridge Painting Construction, Luh M. Chang, Machine Hsie
JTRP Technical Reports
The purpose of this research is to implement the steel bridge painting quality acceptance system developed in the Joint Highway Research Project HPR-2029-89-27 and to computerize the developed system into inspectors’ daily practice. A training program was conducted. Field experiment of the developed inspection system was initiated immediately right after the inspector training program. The new acceptance system was manually tested. Feedback from INDOT’s inspectors and other personnel were adopted to refine the inspection system. Meanwhile, an interactive computer graphic program was developed to assist the INDOT in designing the double sampling plan and deciding the sample size with controlled …

An Indot Lessons Learned Constructability Program And Integrated Multimedia System, Bob G. Mccullouch, Robert Michael Patty
JTRP Technical Reports
To improve constructability, experienced design and construction engineers often select processes and develop details that require less labor, equipment, or management resources to build. These innovative ideas, enabling circumstances, and their effect on the construction process are not usually recorded in a reusable format. Without such a mechanism, recalling this experience under the appropriate circumstances, or transferring the technology to new management has generally not happened. Further, civil engineers are generally educated to optimize cost by minimizing the material quantity. Through experience gained after graduation, they are expected to pick up options for engineering impact on the labor, equipment, and …
The Components And Benefits Of An Advanced Surface Arterial Traffic Management System, Ted M. Andrews, Kumares C. Sinha
The Components And Benefits Of An Advanced Surface Arterial Traffic Management System, Ted M. Andrews, Kumares C. Sinha
JTRP Technical Reports
Traffic congestion has become an increasing problem on major surface arterial roadways. Demand for accessibility to adjacent land uses yields increased vehicular turning movement activity at driveways and intersections. As turning and cross-road traffic volumes increase, the need for traffic signalization will eventually be warranted. When numerous, independently operating traffic signals are present on a given arterial roadway, adverse effects can result. First, continous movement along the arterials at a desirable speed may not be assured. Second, vehicular delay will increase because of the slower operating speeds and increased number of stops. Third, safety can be threatened as poor traffic …
The Development Of A Prototype Congestion Management System For The State Of Indiana: Phase 1, Nishantha R. Gunawardena, Kumares C. Sinha
The Development Of A Prototype Congestion Management System For The State Of Indiana: Phase 1, Nishantha R. Gunawardena, Kumares C. Sinha
JTRP Technical Reports
This study details a comprehensive set of guidelines and a work-plan that consists of nine elements that need to be developed in implementing a congesion management system. A procedure has been developed by means of which congestion on roadway links can be identified at a macroscopic level using daily volume counts (ADT) after which, links that are identified as being congested will be subjected to a more detailed microscopic study using hourly volume counts to determine extent, duration and severity of congestion.

Landfill Leachate Production And Gas Generation Numerical Model, John Edward Riester Jr.
Landfill Leachate Production And Gas Generation Numerical Model, John Edward Riester Jr.
Civil & Environmental Engineering Theses & Dissertations
Numerous processes occur in landfills which lend themselves to modeling. Many of the processes are mutually interdependent. An unsteady numerical model is developed combining the major processes. The three-dimensional moisture transport equations and boundary conditions are solved using an implicit finite difference scheme. The boundaries are determined through a two-dimensional runoff model for the landfill surface and a one-dimensional leachate liner flow model at the bottom of the landfill. The runoff model accounts for evapotranspiration, runoff, infiltration, and leachate recirculation. Richard's equation is solved for saturated and unsaturated vertical flows and Darcy's Equation is solved for lateral flow between adjacent …
