Borman Expressway Atms Equipment Evaluation, J. V. Krogmeier, Kumares C. Sinha, Michael P. Fitz, Srinivas Peeta, Shimon Y. Nof

JTRP Technical Reports

An Advanced Traffic Management System (ATMS) is under development in northern Indiana by the Indiana Department of Transportation (INDOT) in conjunction with Hughes Transportation Management Systems. The study area comprises a sixteen mile segment of the heavily used Borman Expressway and its associated corridor; beginning at the Indiana/Illinois border and stretching east to the Indiana Toll Road interchange. The most important operational problem on the Borman is non-recurrent congestion, arising primarily through accidents and stalled vehicles. In order to mitigate the significant bottleneck delay problems due to non-recurrent congestion, INDOT is developing an ATMS for real-time incident detection and response …

Use Of Gps To Enhance Mapping By Photogrammetry, Robert D. Feeney, James Samuel Bethel, Boudewijn H. W. Van Gelder, Steve Johnson Jan 1996

Use Of Gps To Enhance Mapping By Photogrammetry, Robert D. Feeney, James Samuel Bethel, Boudewijn H. W. Van Gelder, Steve Johnson

JTRP Technical Reports

This research has sought to demonstrate the benefits of kinematic GPS in conjunction with photogrammetric aerial triangulation for mapping purposes. The work was performed with the existing INDOT aerial camera which is quite old, and while this affected the accuracy of the results, the demonstration of capability with a likely potential for excellent results was achieved. Ground point accuracies from the strip were in the sub-meter range with only a single control point. This is contrasted with full-model control requiring 50-80 control points for such a strip. In order to bring accuracies down to an acceptable level, i.e. sub decimeter, …


Use Of Coal Combustion Residues And Foundry Sands In Flowable Fill, Subnahmanya T. Bhat, C. W. Lovell Jan 1996

Use Of Coal Combustion Residues And Foundry Sands In Flowable Fill, Subnahmanya T. Bhat, C. W. Lovell

JTRP Technical Reports

The purpose of the present study is to investigate the use of waste foundry sand in flowable fill. However, the concepts developed are applicable to flowable fills containing any type of sand. Even though the flowable fill is presently popular as a trench filling material, this study addresses a much broader perspective in order to be able to develop uses of this material in geotechnical applications. In this research, only green sands were taken. The fly ash used was class F type. Flowability, hardening characteristics and 28-day unconfined compressive strength are studied. A rational approach the mix design of flowable …


Using Pyrolized Carbon Black (Pcb) From Waste Tires In Asphalt Pavement (Part 1, Limestone Aggregate), Taesoon Park, C. W. Lovell Jan 1996

Using Pyrolized Carbon Black (Pcb) From Waste Tires In Asphalt Pavement (Part 1, Limestone Aggregate), Taesoon Park, C. W. Lovell

JTRP Technical Reports

This study presents the viability of using PCB as an additive in hot mix asphalt concrete. Different ratios of PCB (5%, 10%, 15%, and 20% by weight of asphalt) were blended with two grades of asphalt (AC-10 and AC-20). The complete behaviors of the PCB modified asphalt concrete were investigated by comprehensive laboratory testing and evaluation. The Marshall method was used to determine the optimum binder content and the mechanical properties and void relationships were investigated by this method. The Gyratory Testing Machine was used to define the stress-strain relationships of the PCB mixtures. The rutting potential of PCB mixtures …


Indot Constructability Multimedia System Working Module, Bob G. Mccullouch Jan 1996

Indot Constructability Multimedia System Working Module, Bob G. Mccullouch

JTRP Technical Reports

Constructability can be defined as incorporating knowledge into the design product or designing so it is easier to construct. Transportation facilities have suffered from this problem, with INDOT no exception. The most important feature of any constructability program is capturing field examples, commonly referred to as “lessons learned,” and archiving and retrieving them into future projects that are either similar or have similar conditions in order to eliminate or prevent the same mistakes from occurring again. A mechanism or tool that can perform this task would be a valuable asset for INDOT. A previous JHRP project title “An INDOT Lessons …


Effective Scheduling Of Road And Bridge Closures: Phase 2, Kumares C. Sinha, Mithilesh K. Jha Jan 1996

Effective Scheduling Of Road And Bridge Closures: Phase 2, Kumares C. Sinha, Mithilesh K. Jha

JTRP Technical Reports

This research provides a study on work zone impact analysis. In case of multiple road closures, the network approach is used to find an effective scheduling such that the total user delay is reduced. A dynamic model for analyzing the work zone impact during the period when network is in transition state is also developed. A salient feature of the dynamic model is drives’ perception updating model, which incorporates availability and the quality of information as perceived by drivers.

In addition, a number in in-situ lysimeter water samples were also tested during and after construction. In each case, water samplers were evaluated in terms of their constitutive organic and metal concentrations, as well as their relative bioassay response using a MicrotoxTM protocol. The geotechnical work included monitoring of ash water content and unit weight during placement, settlement analysis, …


Sources, Measurements, And Effects Of Segregated Hot Mix Asphalt Pavement, Ronald. Christopher Williams, Gary R. Duncan, Thomas D. White Jan 1996

Sources, Measurements, And Effects Of Segregated Hot Mix Asphalt Pavement, Ronald. Christopher Williams, Gary R. Duncan, Thomas D. White

JTRP Technical Reports

There are several factors that lead to segregation. Segregation can occur during stockpiling and handling of aggregate and during mixing, storage, transport and lay down of the asphalt mixture. Sometimes segregation may result from a single source or from a combination of sources. Nondestructive test methods have been examined to determine their effectiveness in detecting segregation. These methods include thermal imaging, air penneability, nuclear moisture (asphalt) and density, and permittivity. Based on the effective of these technologies in a laboratory environment, the standard moisture/density nuclear gauge technology was field tested with a high degree of success. Use of four minute …


A Case Study In Synchronous Parallel Discrete Event Simulation, José Miguel Alonso, José A.B Fortes Dec 1995

A Case Study In Synchronous Parallel Discrete Event Simulation, José Miguel Alonso, José A.B Fortes

Department of Electrical and Computer Engineering Technical Reports

This paper considers the suitability of SPED, a synchronous parallel discrete event simulator, for the study of message passing networks. The simulation algorithm is described, and its potential performance is assessed showing that, under some simplifying assumptions, SPED might offer speedups directly proportional to the number of processors used in the simulation. An implementation of SPED in a distributed memory parallel system is used to study a model of an interconnection network for a multicomputer. Experiments show that SPED performs nearly as expected, as long as the event density imposed on the LPs is above a certain threshold. If this …

An Evaluation Of Implementations Of The Cmb Parallel Simulation Algorithm On Distributed Memory Multicomputers, José Miguel, Agustin Arruabarrena, Ramon Beivide, José A..B. Fortes Dec 1995

An Evaluation Of Implementations Of The Cmb Parallel Simulation Algorithm On Distributed Memory Multicomputers, José Miguel, Agustin Arruabarrena, Ramon Beivide, José A..B. Fortes

Department of Electrical and Computer Engineering Technical Reports

A model of a message-passing network is used to analyze the behavior of three implementations of the Chandy-Misra-Bryant parallel simulation algorithm. The characteristics of the model, the organization of the logical processes that constitute the simulator and the characteristics of the host parallel computer have a definite influence on the achieved performance, measured in terms of speedup. Large, loaded models help CMB to synchronize with a minimum overhead, efficiently exploiting the available parallelism. Mapping several LPs onto each processor achieves a better use of the available processing power, because while a LP is blocked (synchronizing) others can use the CPU. …

A Multistage Approach To The Hopfield Model For Bi-Level Image Restoration, Mona S. Badie, Okan K. Ersoy Sep 1995

A Multistage Approach To The Hopfield Model For Bi-Level Image Restoration, Mona S. Badie, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

It was shown in previous published work that the neural networks Hopfield model cam be an efficient tool in grey level image restoration by reganding the problem as a minimization of a two part cost measure, in which one component measures roughness, and the other measures distance from the original image. In this thesis, a multistage approach to the Hopfield network to restore bi-level images degraded by noise is considered where the problem of error minimization is addressed locally within each partition while the other partition is frozen. The natural choice for partitioning was into two stages, minimizing the odd …
