A Real-Time Offset Transitioning Algorithm For Coordinating Traffic Signals, Darcy M. Bullock, Montasir Abbas Jan 2001

A Real-Time Offset Transitioning Algorithm For Coordinating Traffic Signals, Darcy M. Bullock, Montasir Abbas

JTRP Technical Reports

This report introduces an adaptive real-time offset transitioning algorithm that can be viewed as an integrated optimization approach designed to work with traditional coordinated-actuated systems. The Purdue Real-Time Offset Transitioning Algorithm for Coordinating Traffic Signals (PRO-TRACTS) adds to the controllers the ability to adaptively change their offsets in response to changes in traffic pattern, providing an intermediate solution between traditional coordinated-actuated control systems and adaptive control systems. To facilitate implementation, a new National Transportation Communication for ITS Protocol (NTCIP) object for capturing detector actuation at the controller’s level is defined in this report. The unique cycle-based tabulation of volume and …


An Analysis Of Speed Limit Policies For Indiana, Nisar M. Khan, Kumares C. Sinha Jan 2001

An Analysis Of Speed Limit Policies For Indiana, Nisar M. Khan, Kumares C. Sinha

JTRP Technical Reports

The repeal of the National maximum Speed Limit law in 1995 enabled individual states to set their own speed limits. Speed limits are necessary to ensure mobility while preserving highway safety. It is important that states continually monitor and evaluate existing operating speeds in the context of changing patterns of travel, and changing characteristics of highways, vehicles, drivers, and land-use. Any efforts to review existing speed limits should be accompanied by evaluation of policy impacts such as safety and economic productivity. The goal of this research is to develop a set of speed limit policy guidelines for the state. The …


Development And Application Of Linear Scheduling Techniques To Highway Construction Projects, D. J. Harmelink, Rene Antonio Yamin Jan 2001

Development And Application Of Linear Scheduling Techniques To Highway Construction Projects, D. J. Harmelink, Rene Antonio Yamin

JTRP Technical Reports

Crucial to the successful outcome of major highway construction and reconstruction projects today is the ability to accurately plan, predict and control the construction process. Evermore sensitive to budget control, schedule control, resource allocation and impacts on the motoring public, highway constructors today require sophisticated project management tools to achieve project goals. One of the tools recently being used across the country is project scheduling. The use of scheduling techniques on highway projects has grown out of the successful application of these methods to building construction for the past 20 to 30 years. Unfortunately, the effective application of traditional scheduling …


Design Guidelines For Deploying Closed Loop Systems, Andrew P. Nichols, Darcy M. Bullock Jan 2001

Design Guidelines For Deploying Closed Loop Systems, Andrew P. Nichols, Darcy M. Bullock

JTRP Technical Reports

Closed loop systems are becoming the preferred method of operating coordinated traffic signal systems. Some of the benefits of a closed loop system include remote controller access, synchronization of controller time clocks, and orderly transition between coordination plans. With ensured time clock synchronization, the coordination of traffic signals becomes more reliable, which leads to optimal vehicle progression through the system. However, due to the complexity and relative infrequent implementation in more rural districts of closed loop systems, it is very difficult to obtain a successful deployment. This manual provides a step-by-step procedure for designing the parameters, implementing, testing, and field …

Development Of A Procedure To Identify Aggregates For Bituminous Surfaces In Indiana, Terry R. West, Kyu H. Cho Jan 2001

Development Of A Procedure To Identify Aggregates For Bituminous Surfaces In Indiana, Terry R. West, Kyu H. Cho

JTRP Technical Reports

Adequate friction resistance is needed to prevent pavement slipperiness allowing vehicles to stop in a reasonable distance. For stone mastic asphalt surfaces, friction resistance is mainly a function of the interaction between the aggregates exposed at the road surface and vehicle tires. Aggregate performance is reduced with time by wear and polishing as a consequence of vehicular traffic. In this research a method to investigate performance based on physical, chemical and petrographic factors has been evaluated. The objective was to develop a laboratory method to test Indiana dolomite, limestone, sandstone, and gravel aggregates to predict friction resistance in the field …


Development Of Improved Pavement Performance Prediction Models For The Indiana Pavement Management System, Sedat Gulen, Karen Zhu, John Weaver, Jie Shan, William F. Flora Jan 2001

Development Of Improved Pavement Performance Prediction Models For The Indiana Pavement Management System, Sedat Gulen, Karen Zhu, John Weaver, Jie Shan, William F. Flora

JTRP Technical Reports

The Indiana Department of Transportation (INDOT) is increasingly committed to the Pavement Management System. For this reason, updated simple pavement performance prediction models with the least number of explanatory (independent) variables are required to predict the performance of various pavement types for future planning of rehabilitation or replacement. In Indiana, the two main pavement types are jointed concrete pavement (JCP) and bituminous pavement (BIT). 1999 and 2000 year data were used to develop regression models for different pavement types for the Interstate and Non- Interstate Roads systems. The International Roughness Index (IRI), in inches per mile, was mainly used for …

Evaluation Of The Implementation Of Hot Pour Sealants And Equipment For Crack Sealing In Indiana, David R. Ward Jan 2001

Evaluation Of The Implementation Of Hot Pour Sealants And Equipment For Crack Sealing In Indiana, David R. Ward

JTRP Technical Reports

This study was initiated as an implementation effort that would monitor, assist with and report on a new maintenance activity involving the trial use of hot pour crack sealant. Work associated with this new activity was qualitatively assessed over a period of several years. INDOT began by purchasing six oil-jacketed melters that were distributed to various sub-districts. Previous INDOT research indicated using hot pour sealant might save on labor expense because it lasted significantly longer than the current emulsion. Random observations were made of various sub-district crews using hot pour sealant and the results were reported to appropriate personnel. Inspections …

Crime Legends In Old And New Media, Pamela Donovan Jan 2001

Crime Legends In Old And New Media, Pamela Donovan

Dissertations, Theses, and Capstone Projects

This project explores the contemporary meanings and persistence of the "crime legend." A case study approach was used: three crime legends with a considerable history of public debunking were chosen. These cases were: the market in snuff films, the theft of vital organs for black-market transplant, and the abduction of children from theme park restrooms. Current versions circulating in Internet newsgroups and via electronic mail lists were collected. Discussions in Internet newsgroups were examined and twenty regular newsgroup participants were interviewed. The public newsgroup communication environment is such that salience is established by the interlocutors themselves, rather than by the …

Faculty Publications

The cross section and the proton structure function F2 for neutral current deep inelastic e+p scattering have been measured with the ZEUS detector at HERA using an integrated luminosity of 30 pb-1. The data were collected in 1996 and 1997 at a centre-of-mass energy of 300 GeV. They cover the kinematic range 2.7 < Q2 < 30000 GeV2 and 6-10-5 < cursive Greek chi < 0.65. The variation of F2 with cursive Greek chi and Q2 is well described by next-to-leading-order perturbative QCD as implemented in the DGLAP evolution equations.


Government Liability When Cyclists Hit The Road: Same Roads, Same Rights, Different Rules, Emily Hammond Jan 2001

Government Liability When Cyclists Hit The Road: Same Roads, Same Rights, Different Rules, Emily Hammond

Georgia Law Review

Most jurisdictions recognize that negligent construction and maintenance of streets exposes government entities to liability. Thus, motorists, pedestrians, and motorcyclists who are injured due to road defects are usually not barred from bringing suit. Yet when the courts grapple with similar injuries to bicyclists, the results are best described as a tangled wreck. Modern cycling jurisprudence sends unwary riders careening through inconsistent judicial opinions, questionable statutory interpretations, and unsettled policies. This Note examines the legal treatment of cases in which cyclists are injured by road hazards, covering sovereign immunity, the public duty doctrine, nuisance, tort immunity acts, vehicle codes, and …


Real-Time Determination Of Soil Type, Water Content, And Density Using Electromagnetics, Vincent P. Drnevich, Chih-Ping Lin, Quanghee Yi, Janet Elaine Lovell Jan 2001

Real-Time Determination Of Soil Type, Water Content, And Density Using Electromagnetics, Vincent P. Drnevich, Chih-Ping Lin, Quanghee Yi, Janet Elaine Lovell

JTRP Technical Reports

The primary objective of this study was to explore the potential use of electromagnetic characteristics of soils using the Time Domain Reflectometry (TDR) technique to identify physical properties of soils. Three fundamental studies in this exploration are the frequencydependent electromagnetic properties of soils, the wave propagation in a TDR system, and the inverse analyses of TDR waveforms. The three-phase model for soils was extended to a four-phase model so as to account for the interface effect and hence the soil fineness. The physical parameters of the four-phase model are related to the frequency-dependent dielectric permitivity of the soil through a …


Seismic Design Of Deep Foundations, Antonio Bobet, Rodrigo Salgado, Dimitrios Loukidis Jan 2001

Seismic Design Of Deep Foundations, Antonio Bobet, Rodrigo Salgado, Dimitrios Loukidis

JTRP Technical Reports

Detailed investigations of pile foundations affected by earthquakes around the world since the 1960’s indicate that pile foundations are susceptible to damage to such a degree that the serviceability and integrity of the superstructure may be affected. Although numerous cases of seismically damaged piles are reported, the detailed mechanisms causing the damage are not yet fully understood. As a consequence, an effective seismic design of pile foundations has not been yet established in practice. Many road bridge structures supported on piles exist in southern Indiana. This is a region where the risk of occurrence of a dangerous earthquake is high …

The Technologies Of Property Rights: Choice Among Alternative Solutions To Tragedies Of The Commons, Bruce Yandle, Andrew P. Morriss Jan 2001

The Technologies Of Property Rights: Choice Among Alternative Solutions To Tragedies Of The Commons, Bruce Yandle, Andrew P. Morriss

Faculty Scholarship

Garrett Hardin's classic description of the tragedy of the commons tells us that all environmental problems require a property rights solution. The property solution or rule may call for the definition and enforcement of common, public, or private property rights, but any escape from the tragedy requires some rationing mechanism that allocates a form of property rights to some entity. These solutions fall into one of two broad traditions within economics: the Pigouvian, or regulatory tradition, and the Coasean, or market-based tradition. Any proposal for action in either tradition implies some definition of property rights. The difference lies in the …

An Efficient Indirect Branch Predictor, Yul Chu, M. R. Ito Jan 2001

An Efficient Indirect Branch Predictor, Yul Chu, M. R. Ito

Electrical and Computer Engineering Faculty Publications

In this paper, we present a new hybrid branch predictor called the GoStay2, which can effectively reduce indirect misprediction rates. The GoStay2 has two different mechanisms compared to other 2- stage hybrid predictors that use a Branch Target Buffer (BTB) as the first stage predictor: Firstly, to reduce conflict misses in the first stage, a new effective 2-way cache scheme is used instead of a 4-way setassociative. Secondly, to reduce mispredictions caused by an inefficient predict and update rule, a new selection mechanism and update rule are proposed. We have developed a simulation program by using Shade and Spixtools, provided …

Assessment As A Scholarship Of Teaching, Judith K. Litterst, Paula Tompkins Jan 2001

Assessment As A Scholarship Of Teaching, Judith K. Litterst, Paula Tompkins

Journal of the Association for Communication Administration

This article examines the position of academic institutions on the need for continued commitment to assessment and at the same time deals with strong faculty sentiment on the subject. The article proposes to re-conceptualize assessment activity as a scholarly process whose products make a contribution to the broader conversation about teaching and learning in higher education. In making a case for this rightful elevation of assessment activity by members of the academy, it will first show that assessment is not service, but scholarship. Second, it will discuss assessment as a legitimate form of research that meets both the definition and …


Administrative Strategies For Successful Adoption Of Computer Technology, Aitken E. Joan, Leonard J. Shedletsky Jan 2001

Administrative Strategies For Successful Adoption Of Computer Technology, Aitken E. Joan, Leonard J. Shedletsky

Journal of the Association for Communication Administration

The article offers strategies that university administrators may use for successful adoption of computer technology. A 1998 survey showed that two thirds of colleges failed to strategically plan their technological implementation. Administrators will want to seriously participate in strategic planning so that technology fits with other goals and expectations in the college or university. Technology use can be overwhelming, so both students and faculty need strong support for using technology. When equipment or connections fail in the middle of a class session, faculty need backup systems and support staff who can solve the technical problems. For success, administrators will want …

Unique Characteristics Of A Graduate Program In Applied Communication, Stuart M. Schrader, Kim White Mills, Robert Dick Jan 2001

Unique Characteristics Of A Graduate Program In Applied Communication, Stuart M. Schrader, Kim White Mills, Robert Dick

Journal of the Association for Communication Administration

This paper addresses one Communication Department's sojourn in designing, developing, and proposing a unique Master of Arts in Applied Communication. Our discipline has long acknowledged the importance of applied communication scholarship and the marketplace has frequently confirmed the importance of providing applied communication knowledge to produce employees who are competent communicators. We are, however, still without terminal graduate programs that are rooted in the foundation of applied communication. Our department's program is reflexively framing its program using applied communication assumptions.
