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

JTRP Technical Reports

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

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

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

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 …

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 …

Glass Transition Behavior Of Pmma Thin Films, Moses T. Kabomo, Frank D. Blum

Chemistry Faculty Research & Creative Works

In the last decade there has been an increased interest in the study of the properties of supported thin polymer films. This has been prompted by the incorporation of thin films into device applications and many other technologies. Although not without controversy, a large body of experimental work indicates departures from bulk behavior by thin films. Strong evidence from both theoretical and experimental work shows that the interaction of polymer with a substrate alters the polymer conformation and mobility. A variety of techniques has been employed to probe the mobility of thin supported polymer films. Some of these techniques indirectly …

The Geography Of Injustice: Borders And The Continuing Immiseration Of California Agricultural Labor In Era Of "Free Trade", Don M. Mitchell

Richmond Journal of Global Law & Business

Why is it that when the reigning ideology governing the expansion of “free trade” is anti-regulatory”, all agree that the movement of people, or rather laborers, must be carefully regulated? Indeed, why are borders strengthened for people just as states of the Western Hemisphere embark on a thorough reconfiguration, and even a dismantling, or borders for capital and goods.

Permeability Performance Of High-Performance Concrete Subjected To Various Curing Regimes, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Concrete technology has continued to advance throughout the years to meet the demands of designers and innovative structural systems. Traditionally, the most common means to specify durable concrete has been via specifying a maximum water-to-cementitious material ratio or a minimum cement content. With the advent of high-performance concrete (HPC), which often has higher contents of cementitious materials and a variety of admixtures, questions about permeability performance and alternative methods to specify durable concrete have arisen. The study conducted herein comments on the applicability of prescriptive specifications for HPC and investigates the influence of curing regimes and concrete temperature development during …
