By most forecasts, the U.S. population is projected to grow by over 100 million by 2050. As demand for transportation increases and our methods of transportation change and evolve, so too will transportation-related noise. The Bureau of Transportation Statistics (BTS) has started a national, multi-modal transportation noise mapping initiative to fa

Transportation construction activities involving in-stream work can mobilize sediment and elevate turbidity, which can affect sensitive aquatic species such as freshwater mussels. Although cofferdams are used to isolate construction areas and limit sediment mobilization, their installation and removal create some degree of sediment release as a res

A large number of types of retaining devices can be used for design, but their limitations, recommendations and guidelines are scattered in the technical literature. A synthesis study has been conducted in which different technologies have been investigated to develop guidelines for the use of the different types of retaining devices. For this purp

The nighttime fatality rate on the Nation’s roadways is three times higher than the daytime rate, and 76 percent of pedestrian fatalities occur at night. Enhancing nighttime visibility where non-motorists mix with traffic during darkness will save lives. The focus is to deploy countermeasures that improve nighttime visibility to safely connect peop

Annual federal apportionments and Indiana state revenues are not sufficient to maintain and improve state highways so innovative approaches in transportation project financing should be sought. There are several available innovative financing techniques associated with the use of federal funds. Although they do not provide new sources of revenue an

The first objective of this study is to quantify the safety effectiveness of WWD countermeasures like CMFs. The second objective of this study is to assess the economic viability of WWD countermeasures.
Innovative financing techniques can complement current methods of financing highway projects in Indiana. Annual federal apportionments and Indiana state revenues are not sufficient to maintain and improve state highways, so innovative approaches in transportation project financing should be sought.

The Federal Highway Administration (FHWA)and the Environmental Protection Agency (EPA)recommend the use of ground count-based programs for the estimation of vehicle-miles traveled. The Highway Performance Monitoring System (HPMS), which is being used by State DOTs, is a program developed by the FHWA for the monitoring of the nation’s highway infras

Procedures developed for the estimation of Vehicle-Miles of Travel (VMT) have been fraught with problems of inaccuracy. Emphasis on environmental issues (air quality), as mandated by current regulations (CAAA, ISTEA-91, and TEA 21), requires State DOTs to accurately estimate travel on their highway infrastructure. The Federal Highway Administration

The concept of using existing INDOT Weigh-In-Motion equipment, a laptop computer, and wireless communication equipment, to develop a virtual weigh station system was proposed for deployment in Indiana in 1998. The Virtual Weigh Station screening tool developed in this project allows officers to read the weights of vehicles crossing WIM scales, in r

Overweight trucks shorten highway life and indirectly increase the costs of maintaining roads. Improved methods for enforcement of commercial vehicle weight laws may increase the number of overweight vehicles caught, thereby prolonging highway life. Improved enforcement may also reduce the number of illegally operating vehicles. This report describ

The purpose of this study was to evaluate if the majority of the signs currently by INDOT will meet the new minimum requirements proposed by the FHWA. In addition, this study provides quantitative data to assess the effectiveness of the current sign replacement program used by the Indiana Department of Transportation (INDOT) and determine if the cu
