Impact Of Camera And Lighting Position On Video Detection Precision, Avery Rhodes, Kristofer Jennings, Darcy M. Bullock

JTRP Technical Reports

On well-illuminated approaches, vehicle headlight reflections on the pavement were observed to cause video detection units to activate early. This early activation results in a dramatic increase in the length of the effective vehicle detection zone. This observed variation in the effective length of the vehicle detection zone that varies by ambient lighting condition and camera placement presents a very serious impediment for traffic engineers to design vehicle extension intervals that operate correctly during day, night and transition periods. Furthermore, the stochastic variation in the length of the vehicle detection zone length has the potential to create driver expectancy issues. …

Remediation Of Aromatic Hydrocarbons In Low Permeability Soils: Updating The Remediation Decision Tree (Synthesis Study), Inez Hua, Andy Hopf

JTRP Technical Reports

Because of the large number of technologies for in situ remediation, the very different types of contaminants to which these technologies are applicable, and the wide range of field conditions, it can be difficult to choose an optimal technology for a specific site. Sorting and prioritizing the various factors which contribute to the success of a particular clean-up can be daunting. Furthermore, non-technical factors, such as those in the legal, political, or financial realm, may also influence which technology is ultimately chosen. Most in situ treatment methods are effective in permeable soil. However, much of Indiana soil is low-permeability, so …

Family Of Compaction Curves For Chemically Modified Soils, Radha Krishna Daita, Vincent P. Drnevich, Daehyeon Kim

JTRP Technical Reports

Lime and Lime Kiln Dust (LKD) are widely used for modifying/stabilizing pavement subgrades. The addition of lime or LKD involves chemical processes that are dependent on many parameters. For natural subgrades, quality control is based on moisture and unit weight requirements using manual interpolations of one-point test data on a family of curves. For modified soils, moisture and unit weight measurements are insufficient for quality control and other tests must be considered. Various possible quality control methods for LKD-modified subgrades were evaluated. This research produced an Excel-based program to automate the generation of a family of curves and one-point data …

Frictional Resistance Of Aggregates For Hot-Mix Asphalt Pavements, Joan Patricia O'Brien, John E. Haddock

JTRP Technical Reports

In 1997 the Indiana Department of Transportation adopted the Superpave mixture design method and attendant specifications for hot-mix asphalt pavements. Prior to Superpave, the Indiana Department of Transportation aggregate frictional requirements were based on average daily traffic volumes and were divided into low, medium, and high volume categories. With the implementation of Superpave in Indiana, aggregate frictional requirements were reassigned to categories based on equivalent single axle load values. The purpose of the research is to determine whether average daily traffic or equivalent single axle load has a greater effect on the frictional resistance of a hot-mix asphalt pavement, to …

A Highway Travel Information System: Forecasting And Publicizing Delays In The Indiana State Highway Network, Shu-Ling Yu, Jon D. Fricker

JTRP Technical Reports

The Highway Travel Information System (HTIS) is a long-term pre-trip information system providing information about expected events, such as road construction. The HTIS can be beneficial to both highway travelers and roadway project schedulers. Project schedulers can use the HTIS to check the forecasted traffic impacts of a proposed construction project schedule. If the schedule would cause unacceptable delays, a scheduler can try new schedules to reduce the delay. Travelers who have flexible schedules and would like to do pre-trip planning can obtain knowledge of traffic conditions in the near future from HTIS to avoid unnecessary delays. An approach called …

An Analysis Of Seismic Hazards In Indiana, Jennifer Haase, Robert Nowack, Chi Hyun Park, Alison Hunyar, John Hill, Michael Hamburger

JTRP Technical Reports

Current USGS probabilistic seismic hazard estimates (Frankel et al., 2002) show a higher seismic hazard in southwestern Indiana than for the rest of the state. This is expected based on past work documenting large pre-historic events in the Wabash Valley, and also based on isoseismal levels of shaking from the New Madrid 1811-1812 earthquakes. When assessing the hazard on a county by county basis, the local soil conditions produce amplification of shaking in regions with soft or unconsolidated sediments relative to firm-rock sites. We have reproduced the probabilistic seismic hazard calculation following the USGS methodology for the state of Indiana …
